BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a system and method for providing a walking path guidance service based on measurement of a motion of a user, and more specifically, to a system and method for providing a walking path guidance service based on measurement of a motion of a user, which measures a motion and position information of the user using a smart device, calculates an average walking speed using the measured motion and position information, creates a walking path from a starting point to a destination when the destination is input, and calculates a time of arrival at the destination by the average walking speed of the walking path.

Background of the Related Art

A wearable devices is literally a device that can be worn on a human body, and there are various kinds of wearable devices according to wearing portions, such as glasses, a watch, shoes, a ring, a belt, a band, a necklace, a headset, clothes and the like. Such wearable devices are currently in a rapidly distributed stage, and among them, wearable glasses, wearable watches and wearable bands closely related to human life and, at the same time, easy to wear form largest product groups.

On the other hand, the wearable device is also referred to as a smart device in other words. It is since that although initiation of operation by an input of a user is needed, if once the operation is initiated, various additional information can be automatically created and provided to the user thereafter. For example, if a user wearing a wearable watch desires to measure his or her heart rate, the wearable watch measures the heart rate of the user as soon as the user presses a heart rate measurement input button and creates and provides various information to the user based on the measured heart rate. Meanwhile, a lot of wearable devices which do not need initiation of operation by an input of a user also appear recently. For example, a wearable band may continuously measure a heart rate of a user although there is no initiation of operation by an input of a user, and it is highly probable that wearable devices of the future will be developed in a direction that does not need initiation of operation by an input of a user. It is since that convenience of operating a device will be increased as the input of a user is not needed.

The source of various additional information provided by the wearable device to a user is information measured from the user. Accordingly, the wearable device should necessarily install sensors for measuring various information from the user, and the more the kinds of installed sensors, the more information can be measured from the user. Accordingly, recent wearable devices tend to necessarily install a heart rate measurement sensor, a global positioning system (GPS) sensor and a walking count measurement sensor, and studies for installing various kinds of sensors in the limited inner space of the device are continued.

After measuring the information from the user through the installed sensors, the wearable device may create various additional information based on the information and provide the user with the information. For example, the wearable device may measure the current position of the user and provide information on nearby stores or products related to the interest of the user. Although the additional information can be provided through a function of the wearable device itself, since all the additional information needed for different users cannot be provided through one wearable device, applications installed in the wearable device are developed together recently. Here, an application can be regarded as a kind of application program and may perform a function of creating and providing various additional information based on the information measured through a function of the wearable device itself. In the above example, all the information about nearby stores or products related to the interest of the user can be provided by the application. That is, whenever a new application is developed, additional information that can be provided to the user through the wearable device is diversified, and thus development of applications can be regarded as a companion to go forward together with development of the wearable device itself.

Meanwhile, construction of a system capable of making a payment through a wearable device emerges as a main issue in the related industries recently. For example, although a user does not to take out his or her wallet and make a payment, the user may make a payment through a wearable device by installing a near field communication (NFC) function in the wearable device itself and registering a credit card of the user in an application. That is, the wearable device may perform a mobile wallet function on behalf of conventional wallets. However, since there are a lot of problems related to security, such as personal information of a user, approval of card payment and the like, there are a lot of technical problems to be solved.

In addition, a service system for measuring a motion of a user using a wearable device and providing a walking pattern using information on the measured motion has already been constructed. However, a service for providing an estimated time of arrival at a destination according to an average walking speed of a user is not provided yet in the prior art.

FIG. 1 is a block diagram schematically showing the configuration of a device for providing a walking path guidance service based on measurement of a motion of a user according to an embodiment of the present invention. In the embodiment, the device for providing a walking path guidance service may be a smart phone. Hereinafter, although a case of using a smart device as a device for providing a walking path guidance service is described as an example, the device for providing a walking path guidance service according to the present invention is not limited to the smart device.

Referring to FIG. 1, a smart device 100 for providing a walking path guidance service based on measurement of a motion of a user may include a sensor unit 110, a reference information creation unit 120, a walking path guidance unit 130, a storage unit 150 and a control unit 160. In an embodiment, the smart device 100 may further include a personalized service unit 140.

The sensor unit 110 is installed in the smart device 100 and measures a motion or biometric information of a user. Here, the biometric information may include a pulse rate, a blood pressure, blood sugar, blood oxygen saturation (SpO2) and the like.

The sensor unit 110 is a configuration for measuring a motion according to walking of a user and may be a motion sensing sensor. The motion sensing sensor is a sensor for measuring a motion of the feet of a user and may include, for example, an acceleration sensor and the like. The acceleration sensor may sense a motion of a user using a three-axis acceleration sensor axis. The acceleration sensor measures magnitude of acceleration according to a motion of the user. The acceleration sensor measures a degree of acceleration using a physical displacement of a mechanical device configured inside thereof and outputs the degree of acceleration as a frequency or a voltage. For example, the acceleration sensor may follow one of the methods including an inertial type, a gyro type and a silicon type.

The sensor unit 110 may measure biometric information of a user. In this case, the sensor unit 110 senses and converts basic physical properties such as current, voltage, resistance and the like containing biometric measurement information into a data of a desired form. The sensor unit 110 includes corresponding measurement sensors according to the types of measurement objects desired to be measured, such as a pulse rate sensor, a blood pressure sensor, a blood sugar sensor and the like. Since the sensor unit 110 periodically or continuously senses the measured biometric information and transmits an electrical signal corresponding thereto to the control unit in the main body, the user may confirm a result through the smart device 100 or a user terminal or the like connected to the smart device 100, and, in an emergency situation, the user terminal connected to the smart device 100 may directly inform the result to the outside on behalf of the user.

In addition, the sensor unit 110 measures position information, in addition to motion and biometric information of the user. A position sensing sensor is a sensor for measuring the current position of a user and may include, for example, a GPS sensor or the like.

The reference information creation unit 120 calculates an average walking speed using the motion and position information measured by the sensor unit 110. Since the current position of the smart device 100 can be grasped in real-time, the average walking speed can be easily grasped by calculating the moving time and moving distance or through various other methods.

The reference information creation unit 120 calculates an average walking speed of the user using the motion and position information measured by the sensor unit 110. That is, the reference information creation unit 120 detects steps using a motion measurement value of the sensor unit 110. At this point, the reference information creation unit 120 may use a peak value detection method, a preset section detection method, a zero-cross detection method or the like to detect the steps. If the zero-cross detection method is used, the smart device 100 recognizes a moment when a signal passes through a zero point as a step after signal-processing a raw signal of an accelerometer using sliding window summing and signal difference.

Then, the reference information creation unit 120 calculates a moving distance of the user using the position information measured by the sensor unit 110 and analyzes an average number of steps according to the moving distance as a walking pattern. Then, the reference information creation unit 120 obtains an average walking speed by dividing the moving distance by the moving time (average walking speed=moving distance/moving time). At this point, if it is set to measure the speed every few steps, the moving distance is a sum of the strides corresponding to the number of steps, and the moving time a total time taken to complete the walk. If it is set to measure the speed every few seconds, the moving distance is a sum of strides corresponding to the number of steps made within the time, and the set time is the moving time. Then, the moving speed is obtained by dividing the moving distance obtained by the sum of the values of strides as many as the set number of steps by the time taken to move as many as the set number of steps, or if it is set to measure the speed by the time, not the number of steps, the moving speed is obtained by dividing the moving distance obtained as a sum of the values of strides corresponding to the number of steps made as much as the set time by the set time.

The walking path guidance unit 130 creates a walking path from a starting point to a destination and calculates a time of arrival at the destination by the average walking speed of the walking path.

That is, the walking path guidance unit 130 receives a starting point and a destination form the user. If the current position is known by the sensor unit 110, the walking path guidance unit 130 searches for a walking path using the current position as a starting point instead of receiving the starting point. At this point, the searched walking path may be a shortest walking path from the starting point to the destination.

Hereinafter, a method of creating a walking path by the walking path guidance unit 130 will be described. As a first method, the walking path guidance unit 130 receives a starting point and a destination and creates a walking path, and if there is a reduced path passing through the inside of a building among the paths created between the starting point and the destination, the walking path guidance unit 130 may create the corresponding reduced path as a walking path. At this point, the walking path guidance unit 130 stores and manages even the indoor moving path inside the building together with road information. The walking path guidance unit 130 may search for coordinate information of the starting point and the destination, map image information of corresponding coordinates and scale information from the map information stored in the storage unit 150 and create a walking path mainly focused on roads. That is, the walking path guidance unit 130 creates path information mainly focused on roads according to the starting point and the destination and determines whether or not a building which stores an indoor moving path is included in the created path. If there is an indoor moving path as a result of the determination, the walking path guidance unit 130 creates path information including the indoor moving path. Like this, the walking path guidance unit 130 creates at least one or more pieces of path information including the walking path mainly focused on roads and the indoor moving path.

As a second method, the walking path guidance unit 130 creates an optimum walking path considering the number of waiting sections in the walking path and the moving distance between the starting point and the destination. The walking path guidance unit 130 may grasp at least one or more walking paths between the starting point and the destination and create, among the grasped walking paths, a walking path consuming the shortest time as an optimum walking path based on the moving distance and the number of waiting sections including crosswalks.

If a walking path from the starting point to the destination is created in a method as described above, the walking path guidance unit 130 calculates a time required to move to the destination, i.e., an arrival time, of each walking path according to the average walking speed created by the reference information creation unit 120. Then, the walking path guidance unit 130 outputs walking path information including a walking path and an arrival time.

Therefore, the user may be provided with the path information focused on the road, the indoor moving path, the shortest distance moving path and the like and provided with information on a time required, a moving distance, information on entrances and exits of a building to drop in and the like of each path to pass through by confirming the walking path information, walking information and the like through the smart device 100.

The walking path guidance unit 130 displays the walking path from the starting point to the destination on an electronic map. The walking path displayed on the electronic map may be displayed as a shortest walking path among the walking paths from the starting point to the destination. At this point, when the user moves along the walking path, the walking path guidance unit 130 starts to move an identifier, indicating movement of the user on the walking path of the electronic map, at a preset speed. Like this, since an identifier indicating movement of the user is moved on the walking path of the electronic map, the user may approximately confirm a point where the user is currently positioned even while walking.

In addition, the walking path guidance unit 130 may compare the average walking speed created by the reference information creation unit 120 with the current walking speed of the user and output a difference between the average walking speed and the current walking speed through a visual or aural means. If the walking speed of the user is lower than the average walking speed, the walking path guidance unit 130 informs the user that the walking speed of the user is lower than the average walking speed, and in an opposite case, it informs that the walking speed of the user is higher than the average walking speed. At this point, the walking path guidance unit 130 may use a method of an alarm sound, vibration or the like as a method of informing the user of the low or high walking speed, and, for example, the alarm sound or a vibration type of a case when the user should walk slowly is different from the alarm sound or a vibration type of a case when the user should walk fast so that the user may recognize without separately confirming them. If the user adjusts the walking speed to correspond to the average walking speed, the alarm sound or the vibration is stopped so that the user may know that the current speed is a recommended speed.

Since the user is within a range of the average walking speed, the walking path guidance unit 130 may display the current speed together with a message informing to maintain the current speed. That is, if the walking speed of the user is higher than the average walking speed, the walking path guidance unit 130 displays the current walking speed together with a message informing to reduce the walking speed. In addition, the walking path guidance unit 130 also displays the average walking speed. If the walking speed of the user is lower than the average walking speed, the walking path guidance unit 130 displays the current walking speed together with a message informing to increase the walking speed. In addition, the walking path guidance unit 130 also displays the average walking speed.

When a movement according to the walking path of the user is sensed, the personalized service unit 140 calculates a moving speed using the movement measured by the sensor unit 110 and recommends a taxi call service if the calculated moving speed is lower than a preset threshold speed. If the user desires to use the taxi call service, the personalized service unit 140 may search for an unoccupied taxi in the nearest distance from the current position measured by the sensor unit 110 and provide taxi reservation information including the license plate number, an estimated arrival time and the like of the searched unoccupied taxi.

In addition, if the moving speed calculated by using a movement measured by the sensor unit 110 is lower than the preset threshold speed, the personalized service unit 140 determines whether or not the user is in a normal condition by comparing the biometric information of the user measured by the sensor unit 110 with previously stored reference biometric information and outputs abnormal information if the user is in an abnormal condition. At this point, the personalized service unit 140 determines whether or not the user is in a dangerous situation and informs the dangerous situation by way of preset contact information, an emergency contact network or the like if the user is in a dangerous situation.

Meanwhile, the reference information creation unit 120, the walking path guidance unit 130 and the personalized service unit 140 can be implemented by a processor or the like needed to execute a computer program on a computing device. Like this, each of the reference information creation unit 120, the walking path guidance unit 130 and the personalized service unit 140 can be implemented by a physically independent individual configuration or implemented as a form functionally separated within a processor.

The storage unit 150 is a configuration for storing data related to operation of the smart device 100. Here, the storage unit 150 may use a publicized storage medium and may use one or more of publicized storage media such as ROM, PROM, EPROM, EEPROM, RAM and the like.

Particularly, the biometric information measured by the sensor unit 110, a health state related to the biometric information, the average walking speed calculated by the reference information creation unit 120, the walking path created by the walking path guidance unit 130 and the like are stored in the storage unit 150. In addition, map information including map image information, scale information, coordinate information and the like is stored in the storage unit 150. Here, the map information may include indoor moving paths or the like which move from a road to a road.

In addition, a walking path guidance program for providing a walking path guidance service provided by the smart device 100 is stored in the storage unit 150. Electronic map data related to the map information of each area is stored in the storage unit 150. Any file format is allowed as far as the electronic map may display a walking path.

Therefore, the control unit 160 may provide the walking path guidance service provided by the smart device 100 by executing the walking path guidance program stored in the storage unit 150 according to selection of a user.

In addition, an application (or an applet) or the like capable of calculating an average walking speed according to a motion of a user and performing walking path guidance can be stored in the storage unit 150, and the stored information can be selected by the control unit 160 as needed.

The control unit 160 may store an application (or an applet) capable of calculating an average walking speed according to a motion of a user and performing walking path guidance in the storage unit 150 and control to output a walking path by driving the application.

The control unit 160 is a configuration for controlling operation of various constitutional components of the smart device 100, including the sensor unit 110, the reference information creation unit 120, the walking path guidance unit 130, the personalized service unit 140 and the storage unit 150.

The control unit 160 may include at least one arithmetic unit, and, here, the arithmetic unit may be a general-purpose central processing unit (CPU), a programmable device element (CPLD or FPGA) implemented to be suitable for a specific purpose, an application specific integrated circuit (ASIC) or a microcontroller chip.

The smart device 100 according to the present invention may further includes an input unit 170 for receiving information from a user. The input unit 170 can be utilized to receive, particularly, a starting point, a destination and the like. Meanwhile, the input unit 170 can be implemented as an input device such as a keypad, a touch panel or the like and also can be implemented as various input devices other than these input devices. In addition, the input unit 170 can be implemented in the form of a touch screen integrated with a display unit 180.

In addition, the smart device 100 according to the present invention may further include the display unit 180 for displaying various information related to the operation of the smart device 100. Particularly, the display unit 180 may display various kinds of information such as the biometric information measured by the sensor unit 110, a health state related to the biometric information, a walking path, a time of arrival at the destination and the like. The display unit 180 can be implemented through various display devices including an LCD, an LED and the like.

In addition, the smart device 100 according to the present invention may further include a power supply unit (not shown) for supplying power. In addition, the smart device 100 of the present invention may further include a short-range communication unit (not shown) for performing short-range wireless communication with a user terminal possessed by a user. The short-range communication unit may operate according to various specifications such as Wi-Fi, Bluetooth communication, Zigbee communication, infrared communication (IrDA), Radio Frequency (RF) communication including Ultra High Frequency (UHF) communication and Very High Frequency (VHF) communication, Ultra Wide Band (UWB) communication and the like.

A service application according to the present invention can be installed in the smart device 100 to provide a walking path guidance service according to the present invention. The service application installed in the smart device 100 implements the walking path service through the control unit 160. The service application may be installed when the smart device 100 is released or may be downloaded through a communication network. Alternatively, the service application can be recorded in a separate memory device in the form of a program file and transferred to the smart device 100 by connecting the memory device to the smart device 100.

The smart device 100 implemented as described above means a device that can be worn on a human body, and there are various kinds of wearable devices according to wearing portions, such as glasses, a watch, shoes, a ring, a belt, a band, a necklace, a headset, clothes and the like.

FIG. 2 is a flowchart illustrating a method of providing a walking path guidance service based on measurement of a motion of a user by a smart device according to the present invention.

Referring to FIG. 2, the smart device measures a motion of a user (step S202) and calculates an average walking speed of the user using the measured motion (step S204). That is, the smart device detects steps using a motion measurement value of the sensor unit, calculates a moving distance of the user using position information, and analyzes an average number of steps according to the moving distance as a walking pattern. Then, the smart device obtains an average walking speed by dividing the moving distance by the moving time (average walking speed=moving distance/moving time).

Thereafter, if a destination is input (step S206), the smart device creates a walking path from a starting point to the destination (step S208). At this point, the smart device receives a starting point and a destination and creates a walking path, and if there is a reduced path passing through the inside of a building among the paths created between the starting point and the destination, the smart device may create the corresponding reduced path as a walking path. In addition, the smart device may create an optimum walking path considering the number of waiting sections in the walking path and the moving distance between the starting point and the destination.

The smart device calculates a time of arrival at the destination of the walking path according to an average walking speed (step S210) and displays the calculated time of arrival at the destination (step S212). At this point, the smart device may display the walking path together with the time of arrival at the destination.

Then, if movement of the user according to the walking path is sensed (step S214), the smart device calculates a moving speed by measuring a motion of the user according to the movement (step S216).

Then, the smart device determines whether or not the calculated moving speed is lower than a preset threshold speed (step S218) and recommends a taxi call service if the calculated moving speed is lower than a preset threshold speed (step S220). If the user desires to use the taxi call service, the smart device may search for an unoccupied taxi in the nearest distance from the current position measured by the sensor unit and provide taxi reservation information including the license plate number, an estimated arrival time and the like of the searched unoccupied taxi.

FIG. 3 is a flowchart illustrating a method of providing a walking path guidance service based on measurement of a motion by a smart device according to the present invention.

Referring to FIG. 3, the smart device measures a motion of a user (step S302) and calculates an average walking speed of the user using the measured motion (step S304).

Thereafter, if a destination is input (step S306), the smart device creates a walking path from a starting point to the destination (step S308).

The smart device calculates a time of arrival at the destination of the walking path according to the average walking speed (step S310) and displays the calculated time of arrival at the destination (step S312). At this point, the smart device may display the walking path together with the time of arrival at the destination.

Then, if movement of the user according to the walking path is sensed (step S314), the smart device calculates a moving speed by measuring a motion of the user according to the movement (step S316).

Then, the smart device determines whether or not the calculated moving speed is lower than a preset threshold speed (step S318).

If the calculated moving speed is lower than the threshold speed as a result of the determination at step S318, the smart device measures biometric information of the user (step S320), compares the measured biometric information with previously stored reference biometric information (step S322), and determines whether or not the user is in a normal condition (step S324).

If the user is in an abnormal condition as a result of the determination at step S324, the smart device outputs abnormal information (step S326), and if the user is not in an abnormal condition, the smart device recommends a taxi call service (step S328). If the biometric information of the user is abnormal, the smart device determines whether or not the user is in a dangerous situation, and if the user is in a dangerous situation, it may inform the dangerous situation by way of preset contact information, an emergency contact network or the like.

FIG. 4 is a view showing a system for providing a walking path guidance service based on measurement of a motion of a user according to another embodiment of the present invention.

Referring to FIG. 4, the system for providing a walking path guidance service based on measurement of a motion of a user includes a smart device 100 and a service server 200, and these are connected through a communication network.

The smart device 100 calculates an average walking speed by measuring a motion of the user, and if a destination is input, the smart device 100 transmits a walking path information request signal including the average walking speed and the destination to the service server 200 and receives walking path information from the service server 200. That is, the smart device 100 detects steps using a motion measurement value of the sensor unit, calculates a moving distance of the user using the position information measured by the sensor unit and analyzes an average number of steps according to the moving distance as a walking pattern. Then, the smart device 100 obtains an average walking speed by dividing the moving distance by the moving time (average walking speed=moving distance/moving time). If a destination is input, the smart device 100 transmits a walking path information request signal including the average walking speed and the destination to the service server 200.

If movement of the user according to the walking path is sensed, the smart device 100 calculates a moving speed by measuring a motion of the user according to the movement and transmits information on the calculated moving speed to the service server 200. Here, the moving speed information may include a moving speed, smart device identification information and the like.

In addition, if the calculated moving speed is lower than a preset threshold speed, the smart device 100 measures biometric information of the user, determines whether or not the user is in a normal condition by comparing the measured biometric information with previously stored reference biometric information, and outputs abnormal information if the user is in an abnormal condition. At this point, the smart device 100 determines whether or not the user is in a dangerous situation, and if the user is in a dangerous situation, the smart device 100 may inform the dangerous situation by way of preset contact information, an emergency contact network or the like.

The smart device 100 means a device that can be worn on a human body, and there are various kinds of wearable devices according to wearing portions, such as glasses, a watch, shoes, a ring, a belt, a band, a necklace, a headset, clothes and the like.

The smart device 100 used in the present invention is characterized by measuring a motion, a position and biometric information of the user. Here, the biometric information may include a pulse rate, a blood pressure, blood sugar, blood oxygen saturation (SpO2) and the like. At this point, the smart device 100 may measure the biometric information by sensing basic physical properties such as current, voltage, resistance and the like containing biometric measurement information such as a pulse rate, a blood pressure, blood sugar, blood oxygen saturation (SpO2) and the like.

An application (or an applet) capable of calculating a moving speed according to a motion of the user can be stored in the smart device 100, and the smart device 100 may output the walking path information provided by the service server 200 through the application.

A service application according to the present invention can be installed in the smart device 100 in order to provide a walking path guidance service according to the present invention. The service application installed in the smart device 100 implements the walking path service through the control unit 160. The service application may be installed when the smart device 100 is released or may be downloaded through a communication network. Alternatively, the service application can be recorded in a separate memory device in the form of a program file and transferred to the smart device 100 by connecting the memory device to the smart device 100.

If the walking path information request signal is received from the smart device 100, the service server 200 creates a walking path from the starting point to the destination, calculates a time of arrival at the destination by the average walking speed of the walking path, and transmits walking path information including the walking path and the time of arrival at the destination to the smart device 100. Here, the walking path information request signal may include smart device identification information, the starting point, the destination, the average walking speed and the like. The service server receives the starting point and the destination and creates a walking path, and if there is a reduced path passing through the inside of a building among the paths created between the starting point and the destination, the service server may create the corresponding reduced path as a walking path. In addition, the service server may create an optimum walking path considering the number of waiting sections in the walking path and the moving distance between the starting point and the destination. Then, the service server calculates a time of arrival at the destination using the distance and the average walking speed of the walking path.

If the moving speed of the smart device 100 is lower than a preset threshold speed, the service server 200 recommends a taxi call service. If the user desires to use the taxi call service, the service server 200 may search for an unoccupied taxi in the nearest distance from the current position of the user, transmit taxi reservation information including the license plate number, an estimated arrival time and the like of the searched unoccupied taxi to the smart device 100 of the user, and transmit the user's position, user identification information (the phone number, the identification information of the smart device and the like) and the like to the driver of the searched taxi.

Such a service server will be described in detail with reference to FIG. 5.

In the above description, the smart device 100 is provided with a display unit and may display path information, a time of arrival at a destination and the like transmitted from the service server 200. However, the smart device 100 may not be provided with a display unit. In this case, the system for providing a walking path guidance service based on measurement of a motion of a user may further include a user terminal (not shown).

As another embodiment of the present invention, the system for providing a walking path guidance service based on measurement of a motion of a user may further include a user terminal for storing and inputting the biometric information measured by the smart device 100 and the path information, the time of arrival at a destination, the taxi call service and the like received from the service server.

Accordingly, in the present invention, since the user terminal is also connected, as well as the smart device 100 and the service server 200, information on a motion is provided to the user even while the user does not wear the smart device 100, and the user may be provided with a taxi call service from the service server 200.

The smart device 100 may transmit the measured motion information, biometric information and position information to the user terminal (e.g., a smart phone) paired with the smart device 100. For example, the smart device 100 may transmit and receive data using a short-range communication network such as NFC or Bluetooth.

The user terminal includes a Personal Digital Assistant (PDA), a smart phone, a cellular phone, a Personal Communication Service (PCS) phone, a Global System for Mobile (GSM) phone, a Wideband CDMA (W-CDMA) phone, a CDMA-2000 phone, a Mobile Broadband System (MBS) phone and the like which can be applied in a variety of wired and wireless environments. Here, although the user terminal may represent a small portable device, embodiments of the present invention will not be specially limited thereto since the user terminal can be referred to as a mobile communication terminal if the user terminal includes a camcorder, a laptop computer or the like.

FIG. 5 is a block diagram schematically showing the configuration of a service server according to an embodiment of the present invention.

Referring to FIG. 5, the service server 200 includes a communication unit 210, a database 220, a walking path service unit 230, a recommendation unit 240 and a control unit 250.

The communication unit 210 may receive a walking path information request from a smart device through a communication network and transmit walking path information created by the walking path service unit 230 to the smart device 100. Here, the communication network includes both wired communication and wireless communication, and the smart device and the service server 200 are connected to each other through the communication networks.

Such a data communication unit 210 may include a variety of wired or wireless communication modules and transmit and receive data according to various wireless or wired communication specifications. For example, the data communication unit 210 can be implemented in a form including various standard communication modules of ITU, IEEE, ISO, IEC and the like or in a form including a variety of communication modules other than the standard communication modules.

The database 220 includes a map database and a user database.

Map information including map image information, scale information, coordinate information and the like is stored in the map database. In addition, indoor moving paths which move from a road to a road are stored in the map database. In addition, walking information including information on a building, indoor moving paths penetrating the inside of a facility, locations of entrances and exits, time for using the entrances and exits and the like are stored in the map database.

User information (a name, an address and the like), biometric information, location information and the like are stored in the user database.

These databases 220 can be implemented to meet the objects of the present invention using a relational database management system (RDBMS) such as Oracle, Infomix, Sybase, DB2 or the like or an object-oriented database management system (OODBMS) such as Gemston, Orion, O2 or the like and may include appropriate fields to accomplish their functions.

Although it is shown in the figure that the database 220 is included in the service server 200, the database 220 and the service server 200 may be separately configured according to the needs of those skilled in the art implementing the present invention.

If a walking path information request signal is received through the communication unit 210, the walking path service unit 230 creates a walking path from the starting point to the destination, calculates a time of arrival at the destination by the average walking speed of the created walking path, and transmits walking path information including the walking path and the time of arrival at the destination to the smart device. That is, if a walking path information request signal including the smart device identification information, the average walking speed, the starting point, the destination and the like is received, the walking path service unit 230 creates a walking path from the starting point to the destination using the map information stored in the map database. At this point, the walking path service unit 230 may create a shortest walking path.

That is, the walking path service unit 230 receives a starting point and a destination and creates a walking path, and if there is a reduced path passing through the inside of a building among the paths created between the starting point and the destination, the walking path service unit 230 may create the corresponding reduced path as a walking path. At this point, the walking path service unit 230 may search for coordinate information of the starting point and the destination, map image information of corresponding coordinates and scale information from map information stored in the map information database and create a walking path mainly focused on roads. That is, the walking path service unit 230 creates path information mainly focused on roads according to the starting point and the destination and determines whether or not a building storing an indoor moving path is included in the created path. If there is an indoor moving path as a result of the determination, the walking path service unit 230 creates path information including the indoor moving path. Like this, the walking path service unit 230 creates at least one or more pieces of path information including the walking path mainly focused on roads and the indoor moving path. In addition, the walking path service unit 230 creates an optimum walking path considering the number of waiting sections in the walking path and the moving distance between the starting point and the destination. The walking path service unit 230 may grasp at least one or more walking paths between the starting point and the destination and create, among the grasped walking paths, a walking path consuming the shortest time as an optimum walking path based on the moving distance and the number of waiting sections including crosswalks.

Then, the walking path service unit 230 calculates a time of arrival at the destination by the average walking speed of the walking path and transmits walking path information including the walking path and the time of arrival at the destination to the smart device.

If the moving speed is received from the smart device, the recommendation unit 240 determines whether or not the moving speed is lower than a preset threshold speed and recommends a taxi call service if the moving speed is lower than a preset threshold speed as a result of the determination. If the user desires to use the taxi call service, the recommendation unit 240 may search for an unoccupied taxi in the nearest distance from the current position of the user and provide taxi reservation information including the license plate number, an estimated arrival time and the like of the searched unoccupied taxi.

Meanwhile, the walking path service unit 230 and the recommendation unit 240 can be implemented by a processor or the like needed to execute a program on a computing device. Like this, each of the walking path service unit 230 and the recommendation unit 240 can be implemented by a physically independent configuration or implemented as a functionally separate form in a processor.

The control unit 250 is a configuration for controlling operation of various constitutional components of the service provider device (4 service server) 200 including the communication unit 210, the database 220, the walking path service unit 230 and the recommendation unit 240.

The control unit 250 may include at least one arithmetic unit, and, here, the arithmetic unit may be a general-purpose central processing unit (CPU), a programmable device element (CPLD or FPGA) implemented to be suitable for a specific purpose, an application specific integrated circuit (ASIC) or a microcontroller chip.

FIG. 6 is a sequence chart showing a method of providing a walking path guidance service based on measurement of a motion according to the present invention.

Referring to FIG. 6, the smart device measures a motion of a user (step S602) and calculates an average walking speed of the user using the measured motion (step S604). That is, the smart device detects steps using a motion measurement value of the sensor unit, calculates a moving distance of the user using the position information measured by the sensor unit, and analyzes an average number of steps according to the moving distance as a walking pattern. Then, the smart device obtains an average walking speed by dividing the moving distance by the moving time (average walking speed=moving distance/moving time). If a destination is input, the smart device transmits a walking path information request signal including the average walking speed and the destination to the service server.

Thereafter, if a destination is input (step S606), the smart device transmits a walking path information request signal including the smart device identification information, the average walking speed, the starting point, the destination and the like to the service server (step S608).

The service server creates a walking path from the starting point to the destination (step S610), calculates a time of arrival at the destination of the walking path according to the average walking speed (step S612) and transmits walking path information including the calculated time of arrival at the destination to the smart device (step S614). At this point, the service server may transmit the walking path together with the time of arrival at the destination.

The service server receives a starting point and a destination and creates a walking path, and if there is a reduced path passing through the inside of a building among the paths created between the starting point and the destination, the service server may create the corresponding reduced path as a walking path. In addition, the service server may create an optimum walking path considering the number of waiting sections in the walking path and the moving distance between the starting point and the destination.

Then, the service server may calculate a time of arrival at the destination using the distance and the average walking speed of the walking path and transmit the calculated time of arrival at the destination to the smart device.

If movement of the user according to the walking path is sensed (step S616), the smart device calculates a moving speed by measuring a motion of the user according to the movement (step S618) and transmits the calculated moving speed to the service server (step S620).

The service server determines whether or not the moving speed transmitted from the smart device is lower than a preset threshold speed (step S622) and recommends a taxi call service if the moving speed is lower than a preset threshold speed (step S624). If the user desires to use the taxi call service, the service server may search for an unoccupied taxi in the nearest distance from the current position measured by the sensor unit, transmit taxi reservation information including the license plate number, an estimated arrival time and the like of the searched unoccupied taxi to the smart device of the user, and transmit the user's position, user identification information (the phone number, the identification information of the smart device and the like) and the like to the driver of the searched taxi.

Since the present invention provides a system and method for providing a walking path guidance service based on measurement of a motion of a user, an estimated time of arrival at a destination according to an average walking speed of the user can be confirmed, and the user may arrive at the destination within the estimated time on foot.

In addition, since a taxi call service is recommended if the moving speed of the user is lower than a predetermined speed or too slow, the user may arrive at the destination within an estimated time.

In addition, if the moving speed of the user is lower than a predetermined speed or too slow, the reasons of delaying the walking can be understood and the health state of the user can be determined by measuring biometric information of the user.

At this point, the wearable device 100â€², a navigation service providing device 200â€², a contents providing server 300â€² and a membership connection device 400â€² are connected through a wired or wireless communication network, and, at this point, the communication network includes a base station controller, a base station transmitter and/or a relay. Here, the base station controller performs a function of relaying signals between the base station transmitter and a switching center. The communication network supports both synchronous and asynchronous types. Accordingly, in the case of the synchronous type, the transmitter of a transmission and reception base station will be a Base Station Transmission System (BTS), and the controller of the transmission and reception base station will be a Base Station Controller (BSC), whereas in the case of the asynchronous type, the transmitter of a transmission and reception base station will be a Radio Tranceiver Subsystem (RTS), and the controller of the transmission and reception base station will be a Radio Network Controller (RNC). It is apparent that the communication network according to an embodiment of the present invention is not limited thereto, and it generally refers to a GSM network, not a CDMA network, and any one that can be used in an access network of a next-generation mobile communication system which will be implemented in the future.

The communication network may further include access points. The access point is a small base station such as a femto or pico base station frequently installed inside a building. Here, the femto or pico base station is categorized by the maximum number of servers and devices based on the classification of small base stations. In addition, the access point includes a short-range communication module for performing short-range communication with a portable terminal, such as Wi-Fi communication or the like. The short-range communication can be performed based on various specifications of Bluetooth communication, Zigbee communication, infrared communication (IrDA), Radio Frequency (RF) communication including Ultra High Frequency (UHF) and Very High Frequency (VHF), Ultra Wide Band (UWB) communication and the like, in addition to the Wi-Fi communication. The access point may extract a position of a data packet, assign a best communication path for the extracted position, and transfer the data packet to a next device, e.g., a wearable device 100â€², along the assigned communication path. The access point may share several circuits in a general network environment.

The access point is largely classified into a fixed access point and a mobile access point. The fixed access point may include a router, a repeater, a relay and the like, and the mobile access point may include a bridge product of a specific manufacturer such as Egg of KT Corporation. Such a mobile access point may read a receiving side address from the transmitting side information and transmit data after assigning a most suitable communication path while guaranteeing free mobility.

In the present invention, each device or server has a transmission and reception unit, and here, the transmission and reception unit includes an RF transmission means for up-converting the frequency of a transmitted signal and amplifying the signal and an RF reception means for low-noise amplifying a received signal and down-converting the frequency of the received signal. The transmission and reception unit may include at least one of a wireless communication module (not shown) and a wired communication module (not shown). In addition, the wireless communication module may include at least one of a wireless network communication module, a Wireless Local Area Network, Wireless Fidelity or Worldwide Interoperability for Microwave Access (WLAN, Wi-Fi or WiMAX) communication module and a Wireless Personal Area Network (WPAN) communication module.

The wireless communication module is a configuration for transmitting and receiving data according to a wireless communication method, and when a device or a server uses wireless communication, it may transmit or receive data for providing payment information using any one of the wireless network communication module, the wireless LAN communication module and the wireless PAN communication module.

FIG. 8 is a view showing an example of providing a navigation service using a wearable device 100â€² according to an embodiment of the present invention.

A system for providing a navigation service using a wearable device 100â€² of the present invention includes the wearable device 100â€², a navigation service providing device 200â€² and a contents providing server 300â€².

More specifically, the navigation service providing system includes a wearable device 100â€² for storing a list of interested products to be purchased, confirming whether a user has entered a store or arrived at a payment location by transmitting and receiving signals to and from a communication device installed in the store, and receiving navigation information data from the navigation service providing device 200â€² and displaying navigation information on the screen if entrance of the user into the store is confirmed; a navigation service providing device 200â€² for receiving the list of interested products from the wearable device 100â€², storing information on in-store products, creating navigation information using the stored information on in-store products and transferring the navigation information to the wearable device 100â€² or a contents providing server 300â€²; and the contents providing server 300â€² for transferring digital contents of interested products recorded in the navigation information received from the navigation service providing device 200â€² to the wearable device 100â€².

At this point, of the term â€˜digital contentsâ€™, the â€˜digitalâ€™ means a method of expressing information, and the contents' generally refers to information, knowledge and database configured in a variety of forms such as a symbol, a character, a sound, a video, a picture, an image and the like, and although the digital contents are contents configured in the form of a character, a sound, a picture, a video and the like distributed using the Internet, they do not mean only information and simple contents, but mean contents of a form containing a transaction and a service as a property for creating an added value using various information techniques. For example, the digital contents include applications related to a service provided by a service provider, which can be transferred to the wearable device 100â€² or a smart terminal device and executed therein, electronic coupons related to a store, electronic coupons related to membership and the like.

In another embodiment of the present invention, the system for providing a navigation service using a wearable device 100â€² may further include a membership connection device 400â€². At this point, the membership connection device 400â€² may perform authentication according to authentication information transferred from the contents providing server 300â€², transfer membership information of a user to the contents providing server 300â€² if it is confirmed that the user is a membership holder as a result of the authentication, and transmit a membership acquisition request message to the contents providing server 300â€² and the wearable device 100â€² if it is confirmed that the user is not a membership holder.

If the navigation service providing system includes the membership connection device 400â€², there is an effect of persuading a user to acquire a membership related to an affiliated company which provides digital contents and a service provider which provides a navigation service platform.

Meanwhile, such a membership connection device 400â€² is an additional component, and a digital contents providing service added to the navigation service can be directly provided to a user without authenticating the membership acquired through the membership connection device 400â€².

FIG. 9 is a view showing an example of providing a navigation service by a wearable device 100â€² according to an embodiment of the present invention.

Referring to FIG. 9, navigation information is provided while showing the products displayed in a store through a display screen of a wearable device 100â€², e.g., a smart glass, and at the same time, product information and discount information can be provided. Alternatively, the same information can be provided through a wearable device having a display screen, such as a smart band.

FIG. 10 is a block diagram showing the configuration of a wearable device according to an embodiment of the present invention.

The wearable device 100â€² of the present invention includes an interested product storage unit 110â€², a user position confirmation unit 120â€², a data transmission unit 130â€², a data reception unit 140â€² and a display unit 150â€². More specifically, the wearable device 100â€² includes an interested product storage unit 110â€² for storing a list of interested products to be purchased; a user position confirmation unit 120â€² for confirming whether a user has entered a store or arrived at a payment location by transmitting and receiving signals to and from a communication device installed in the store; a data transmission unit 130â€² for transferring current position information of the user and data on the list of interested products stored in the interested product storage unit 110â€² to the navigation service providing device 200â€² if entrance of the user into the store is confirmed by the user position confirmation unit 120â€²; a data reception unit 140â€² for receiving navigation information data of an interested product from the navigation service providing device 200â€²; and a display unit 150â€² for displaying navigation information of the interested product received by the data reception unit 140â€².

The interested product storage unit 110â€² stores a list of interested products to be purchased. On the other hand, the interested product storage unit 110â€² may receive and store information on interested products input from an application installed in another smart terminal paired with the wearable device 100â€².

The user position confirmation unit 120â€² confirms whether a user has entered a store and/or arrived at a payment location by transmitting and receiving signals to and from a communication device installed in the store.

At this point, the communication device installed in the store may use Wi-Fi or a beacon. This is a smart terminal short-range communication technique for finding a position of a user within a range of a 50 to 70 m radius and making message transmission, mobile payment or the like possible. Since the short-range communication has an available distance longer than that of near field communication (NFC), it is suitable for O2O service which connects on-line and off-line spaces. If this technique is used, a guidance service, a mobile coupon and the like can be used at a specific location.

This technique is utilized diversely, for example, if a customer using the service enters a store, the customer may automatically confirm product information, customer evaluation and the like and also receive a discount coupon.

In addition, since the short-range communication operates at a low power, consumption of the smart phone battery is low, and it can trace a location in a room more precisely than a GPS, and since a position of a smart phone user can be correctly grasped, it can be utilized for collection of personal information.

If entrance of the user into the store is confirmed by the user position confirmation unit 120â€², the data transmission unit 130â€² transfers current position information of the user and data on the list of interested products stored in the interested product storage unit 110â€² to the navigation service providing device 200â€².

The data reception unit 140â€² receives navigation information data of an interested product from the navigation service providing device 200â€². At this point, if a store manager changes information on a product recorded in the interested product list stored in the interested product storage unit 110â€² using a store terminal, the data reception unit 140â€² may receive product information data updated and stored in a product information database 220â€² of the navigation service providing device 200â€².

At this point, if it is confirmed by the user position confirmation unit 120â€² that the user has arrived at the payment location, the data reception unit 140â€² may further receive digital contents transferred from the contents providing server 300â€².

Meanwhile, in relation to the time point of receiving the digital contents by the data reception unit 140â€², it can be set to receive the digital contents when the user arrives at the payment location, or it may be set to directly provide the digital contents while the user is shopping. Even in the case of providing digital contents when it is confirmed that the user has arrived at the payment location, information on the type of digital contents can be provided for the interested products while the user is shopping.

The display unit 150â€² displays navigation information of the interested product received by the data reception unit 140â€² on the screen. At this point, the display unit 150â€² displays information on a series of operation states and operation results created while performing a function of the wearable device 100â€². In addition, the display unit 150â€² may display a menu of the wearable device 100â€² and user data or the like input by the user. Here, the display unit 150â€² may be configured of a Liquid Crystal Display (LCD), a Thin Film Transistor LCD (TFT-LCD), Organic Light Emitting Diodes (OLED), LEDs, Active Matrix Organic LEDs (AMOLEDs), a flexible display, a three-dimensional display or the like. At this point, the display unit 150â€² may be configured in the form of a touch screen, and when the display unit 150â€² is configured in the form of a touch screen like this, the display unit 150â€² may perform some or all of the functions of an input unit. Particularly, the display unit 150â€² according to an embodiment of the present invention displays navigation information received from the navigation service providing device 200â€² and digital contents transferred from the contents providing server 300â€².

In addition, navigation information and digital contents provided to another smart terminal, e.g., a smart glass, paired with the wearable device 100â€² may be displayed on an application of a smart phone associated with the smart glass.

On the other hand, when the data reception unit 140â€² further receives the digital contents, the display unit 150â€² may simultaneously display the received digital contents on the screen.

FIG. 11 is a block diagram showing the configuration of a navigation service providing device 200â€² according to an embodiment of the present invention.

The camera module 110â€³ photographs images related to visiting a store while moving to the store, which is the object of the visit. This means a camera module 110â€³ embedded in a wearable device 100â€³, and preferably, a camera module 110â€³ mounted on a smart glass can be used. When a camera module 110â€³ mounted on a smart glass is used, it is advantageous in that since images at a point where the eyes stay can be photographed when the camera module 110â€³ moves toward a destination following the eyeline of the user, images related to the destination can be photographed rapidly and correctly compared with a case of using a camera module 100â€³ embedded in a general terminal device such as a smart phone. For example, when the user moves toward a specific destination, it is highly probable that the point where the eyes of the service user stay on the path moving to the destination is the front side and the eyes will stay at specific landmarks, and thus these can be rapidly and correctly photographed.

The history storage unit 120â€³ stores the images photographed by the camera module 110â€³ in relation to visiting the store and information related to the store. At this point, the images related to visiting a store means images of the places photographed every preset time or every preset distance by the camera module 110â€³ while moving to the store, which is the object of the visit. The information related to a store stored in the history storage unit 120â€³ means position information of a place where the camera module 110â€³ photographs images related to visiting a store, path information used to move to the store from the place where the images related to the store are photographed by the camera module 110â€³, information on other stores close to the visited store, and information on the visited store.

Meanwhile, information on the visited store may be information on the location of the store, information on the business type of the store and information on details of using the digital contents at the store.

Meanwhile, it may be set to acquire images every specific time or every specific distance by the service user or the service platform provider. For example, if the moving speed is low, it may be set to acquire an image every two minutes, and if the moving speed is high, it may be set to acquire an image every one minute, and in the case of a complicated area, it may be set to acquire an image at every partitioned road where the service user moves.

The information transmission unit 130â€³ transfers the images related to the store and information related to the store, stored in the history storage unit 120â€³, to the navigation service providing device 200â€³.

The data reception unit 140â€³ receives images related to visiting a store and information related to the store needed to provide a navigation service, from one or more wearable devices 100â€³ of users.

The navigation information database 210â€³ stores the images related to visiting a store and the information related to the store, transferred from the data reception unit 140â€³. At this point, the navigation information database 210â€³ may store images related to visiting a store and information related to the store acquired by a plurality of users using the service.

The navigation information providing module 220â€³ provides navigation information selected using the images related to visiting a store and the information related to the store, transferred from the navigation information database 210â€³.

At this point, referring to FIG. 22, the navigation information providing module 220â€³ may be configured of a distance measurement unit 221â€³, a digital contents provider preference determination unit 222â€³ and a navigation information selection unit 223â€³. More specifically, the navigation information providing module 220â€³ may include a distance measurement unit 221â€³ for measuring a distance to the store, which is the object of the visit, using the information related to the store; a digital contents provider preference determination unit 222â€³ for determining preference, of the digital contents provider providing digital contents, for the navigation service user; and a navigation information selection unit 223â€³ for selecting and providing navigation information according to a preset priority.

The distance measurement unit 221â€³ measures a distance to the store, which is the object of the visit, using the information related to the store. It measures, in real-time, information on the distance the service user has moved from the starting point to arrive at the destination.

The digital contents provider preference determination unit 222â€³ determines preference, of the digital contents provider providing digital contents, for the navigation service user.

Meanwhile, the digital contents provider preference determination unit 222â€³ may determine preference of the digital contents provider for the navigation service user considering at least any one of information among the number of using the digital contents provided by the digital contents provider by the navigation service user, whether or not the navigation service user agrees to provide position information, and a position of the navigation service user according to the provided position information if the navigation service user agrees to provide position information.

The navigation information selection unit 223â€³ selects and provides navigation information according to a preset priority.

At this point, the information on the distance to the store to visit provided by the distance measurement unit 221â€³ and the information on the preference for the navigation service user provided by the digital contents provider preference determination unit 222â€³ can be simultaneously considered. For example, if the distance to the store to visit is within a preset distance, the navigation information selection unit may select navigation information according to the information on the preference for the navigation service user provided by the digital contents provider preference determination unit 222â€³.

On the other hand, the navigation information selection unit may select navigation information by selecting any one of the information on the distance to the store to visit provided by the distance measurement unit 221â€³ and the information on the preference for the navigation service user provided by the digital contents provider preference determination unit 222â€³.

Like this, describing examples of alternatively selecting information, first, if the information on the distance to the store to visit provided by the distance measurement unit 221â€³ is selected, the navigation information providing module may provide shortest distance navigation information for the store to visit, and at this point, shortest distance navigation information for the path actually used by users can be provided based on moved distance, moved time, information on the moving path, images photographed while moving, information related to the photographed images and the like of other users using the navigation service. At this point, if only the GPS information stored in the navigation service provider is utilized, the shortest distance navigation information may not be updated in some cases. For example, if the path is under construction or a real situation is not considered, the shortest path may not be provided. Accordingly, there are occasions in which guidance of road could be wrong although the user travels in a direction actually presented by displaying the navigation information on the display unit, and in this case, the user may select and move along a correct road based on the images photographed by other users while moving to the destination.

Second, if the information on the preference for the navigation service user provided by the digital contents provider preference determination unit 222â€³ is selected, the navigation information providing module may provide navigation information for dropping in nearby stores which can provide digital contents provided by the digital contents provider. For example, although a service of guiding a path to a destination store is provided, this is providing navigation information for dropping in specific stores which can provide the contents provided by a platform company which provides the service or a service provider which provides the digital contents, without considering the shortest distance.

Since the digital contents are provided while a road is guided to drop in a specific store through the guidance service, the service user is persuaded to purchase a product or a service.

Meanwhile, the navigation information providing module 220â€³ may further include an image combination performing unit for combining the navigation information with the images related to visiting a store.

At this point, the image combination performing unit may combine the images photographed by the wearable device 100â€³ of the user in relation to visiting the store and stored in the navigation information database 210â€³ with the images photographed by the wearable devices 100â€³ of other users in relation to visiting the store. At this point, the image combination performing unit may provide images photographed at a place corresponding to the position information currently provided by the navigation information of the user, by utilizing position information contained in the information on the images photographed by other users.

Referring to FIG. 19, an image of a street is displayed in the upper right corner of the display of the wearable device 100â€³ to be separate from the navigation information, and it may doubly confirm through the image whether or not the street corresponds to an area where the user actually passes through. This is conceived to solve the problem that the navigation information provided by a navigation service provider is generally updated after a predetermined period of time is elapsed, from the fact that the images acquired by the navigation service users in real-time can be immediately used. For example, if an image of a road guided by the navigation information corresponds to an image photographed by other users and displayed in the upper right corner, the user moves as is guided by the navigation information, and if the navigation information is information of a previous image, an image acquired while the service user himself or herself or other users move to a corresponding destination is confirmed in the upper right corner of the display unit 150â€³ to be compared in real-time, and, at the same time, a further efficient moving path can be confirmed. At this point, the image may be a form of a picture or a short video.

The data transmission unit 230â€³ transfers the navigation information provided by the navigation information providing module 220â€³ to the wearable device 100â€³. At this point, the data transmission unit 230â€³ may further transfer navigation information provided by the navigation information providing module 220â€³ to the contents providing server 300â€³.
