Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image). A top-down method of arranging a left image and a right image in one frame according to a method in which a left image and a right image are combined into a three-dimensional stereoscopic image, A checker board system in which pieces of a left image and a right image are arranged in a tile form, a left-to-right (right-side) Or an interlaced method in which rows are alternately arranged, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

The sound output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output unit 152 also outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The audio output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 153 may be vibration. The intensity and pattern of the vibration generated in the haptic module 153 can be controlled by the user's selection or the setting of the control unit.

Therefore, the processing unit 520 shown in Fig. 5B can be preferably implemented with a circuit of the type shown in Fig. 5E.

6A and 6B illustrate a structure of a smart shoe according to an embodiment of the present invention.

The smart shoe 200 according to an embodiment of the present invention includes the right shoe 200A and the left shoe 200B and can be classified into a midsole type and a buried type according to the manner in which the load cell module 400 is attached.

FIG. 6A shows a midsole type smart shoe 200. The midsole type smart shoe 200 may include a right shoe 200A and a left shoe 200B. Each of the right shoe 200A and the left shoe 200B may include an insole 223 for body weight measurement. The load cell module 400 may be attached to the lower end of the insole 223 which contacts the inner bottom of the right shoe 200A and the left shoe 200B. Two load cell modules 400 are provided at the lower ends of the insole 223 included in the right shoe 200A and the left shoe 200B so that the right shoe 200A and the left shoe 200B can include two, .

Metal protrusions 601 may be formed on the side surfaces of the right shoe 200A and the left shoe 200B, respectively.

The metal protrusions 601 may be made of a metal material through which electric current can pass, thereby performing the role of an electrode.

The metal protrusion 601 may protrude from the surface of the sole 220. The metal protrusions 601 are arranged on the right side of the shoe so that the right shoe 200A and the left shoe 200B can be connected to each other through the metal protrusion 601 when the user wears both feet while the smart shoe 200 is worn 200A and the left shoes 200B may be formed to correspond to each other in the opposite directions. Specifically, metal protrusions 601 may be formed on the left side surface of the right shoe 200A, and metal protrusions 601 may be formed on the right side surface of the left shoe 200B. Thereby, the metal protrusions 601 are formed at positions opposite to each other between the right shoe 200A and the left shoe 200B.

The metal protrusions 601 may be formed at three sides of each of the right shoe 200A and the left shoe 200B. Thus, when the right shoe 200A and the left shoe 200B are connected to each other through the metal protrusion 601, the metal protrusion 601 acts as an electrode to pass an electric current, whereby the four load cells 301 are connected So that a Wheatstone bridge circuit can be formed.

Referring to FIG. 6A, the metal protrusions 601 are formed at three positions in which the right shoe 200A and the left shoe 200B face each other, that is, positions corresponding to the inside of the foot. In this case, the metal protrusion 601 is not formed at the position opposite to the inside of the foot, that is, the outside of the foot.

The metal protrusions 601 allow the strain gage circuits included in the load cell module 400 to be interconnected to transmit the measured strain and electrical signals. For this, the metal protrusion 601 may be connected to the load cell module 400 attached to the insole 223.

The control module 500 may be attached to the side 602 or the bottom 603 corresponding to the heel inside the smart shoe 200. Depending on the function performed by the smart shoe 200, the control module 500 may be attached only to the right shoe 200A or the left shoe 200B, or to both shoes 200A and 200B. In Fig. 6A, the control module 500 is attached only to the right shoe 200A.

Fig. 6b shows the flush-mounted smart shoe 200. Fig. The flip-type smart shoe 200 may be composed of a right shoe 200A and a left shoe 200B. The load cell module 400 may be embedded in the sole 220 of each of the right shoe 200A and the left shoe 200B. Two load cell modules 400 may be respectively installed in the sole 220 of the right shoe 200A and the left shoe 200B so that the right shoe 200A and the left shoe 200B can include two .

Metal protrusions 601 may be formed on the side surfaces of the right shoe 200A and the left shoe 200B, respectively. The structure, function, and role of the metal protrusion 601 have already been described with reference to FIG. 6A, and a detailed description thereof will be omitted.

The control module 500 may be attached to the side 602 or the bottom 603 corresponding to the heel inside the smart shoe 200. Depending on the function performed by the smart shoe 200, the control module 500 may be attached to only the right shoe 200A or the left shoe 200B, or to both shoe 200A and 200B. In Fig. 6B, the control module 500 is attached only to the right shoe 200A.

7 is a view illustrating a process of measuring a weight by smart shoes according to an embodiment of the present invention.

When the user is on the scale 300, the scale 300 measures the weight of the user. In a similar principle, when the user wears the smart shoes 200 and climbs the sole 220, the smart shoes 200 can measure the weight of the user.

An external pressure is applied to the smart shoe 200 (S701).

Specifically, when the user wears the smart shoes 200, external pressure corresponding to the weight of the user is applied to the smart shoes 200. The external pressure may be applied in a direction perpendicular to the smart shoe 200.

The load cell module 400 included in the smart shoe 200 is deformed (S702).

The load cell module 400 includes an elastic body. Therefore, when a force or a load is applied from the outside, the load cell module 400 can be deformed.

The resistance of the strain gage circuit included in the load cell module 400 changes (S703).

The load cell module 400 is connected to form a Wheatstone bridge circuit (S704).

Specifically, when the right shoe 200A and the left shoe 200B constituting the smart shoe 200 are connected to each other, a current flows through the metal protrusion formed on the side surface of the smart shoe 200, The four load cell modules 400 may be connected to each other to form a Wheatstone bridge circuit.

The control module 500 performs resistance value amplification and A / D conversion (S705).

The Wheatstone bridge circuit includes two fixed resistors and two variable resistors. The control module 500 amplifies and converts the resistance value obtained from the Wheatstone bridge circuit, that is, the change amount of the variable resistor, into digital data, and from this, the weight of the user can be grasped.

The smart shoe 200 outputs the measured load data (S706), and the load data becomes the weight of the user.

Previously, it was impossible to measure a user's weight through a wearable device. In other words, weight measurement was performed through a separate weight measuring device. To perform weight-based health management on a wearable device, the user had to measure the weight separately and directly input measurement data to the wearable device. Therefore, although weight is the most important health indicator for consumers and physicians, there are limitations on weight measurement by time and place.

According to the present invention, the smart shoes 200 as a wearable device can measure the weight regardless of time and place, and perform various health care functions based on the measured weight.

Furthermore, by measuring the weight through smart shoes, which is an essential wearable device device, it is possible to provide a wearable device of a new type capable of weight measurement capable of obtaining a user's liking without giving a sense of resistance to the user.

8A to 8D are diagrams for explaining a Wheatstone bridge circuit formed by connecting load cells included in a smart shoe according to an embodiment of the present invention.

In order to measure an accurate body weight, a Wheatstone bridge circuit is required which is constructed by electrically connecting the four load cells 301 with the four load cells 301.

8A is a view for explaining three wires included in the load cell 301 and the resistance generated thereby. The load cell 301 includes a first wire (White), a second wire (Red), and a third wire (Black). Here, the first wire (White) and the second wire (Red) are connected to each other to generate a fixed resistance. In this case, the generated fixed resistance is smaller than 880 ohms (ohms) and has a relatively fixed value.

The second wire (Red) and the third wire (Black) are connected to each other to generate a variable resistor. In this case, the resulting variable resistance is less than 880 ohms (ohms) but varies with the mechanical pressure exerted by body weight.

Thus, each of the four load cells 301 can include a fixed resistor and a variable resistor.

Fig. 8B shows a circuit composed of four load cells 301. Fig. The circuit in which the four load cells 301 are connected may comprise two fixed resistors 810 and 840 and two variable resistors 820 and 830.

Referring to FIG. 8B, each of the four load cells 301 includes fixed resistors R1A, R2A, R3A, and R4A and variable resistors R1B, R2B, R3B, and R4B. In this case, the fixed resistors R1A, R2A, R3A, and R4A included in the respective load cells 301 are connected to the fixed resistors R1A, R2A, R3A, and R4A of the adjacent load cells 301, R2B, R3B, and R4B are connected to the variable resistors R1B, R2B, R3B, and R4B of the adjacent load cells 301, respectively. As a result, the circuit composed of the four load cells 301 includes two fixed resistors 810 and 840 and two variable resistors 820 and 830.

Fig. 8C shows a Wheatstone bridge circuit obtained from the circuit of Fig. 8B. In Fig. 8B, R1 810 and R4 840 are fixed resistors that are independent of weight. R2 (820) and R3 (830) are variable resistors that vary with body weight. If such a circuit is constituted by a Wheatstone bridge circuit, which is an equivalent circuit, the variation amount of the variable resistors R2 and R3 can be analyzed through the Wheatstone bridge circuit, and the weight of the user can be grasped based on this variation.

Fig. 8D shows an example in which the load cell 301 is disposed in the smart shoe 200. Fig. Two load cells 301 are arranged in the right shoe 200A and the left shoe 200B, respectively, so that a wheatstone bridge circuit can be formed when a pair of shoes constituting the smart shoe 200 are connected . In this case, the right shoe 200A and the left shoe 200B may include the fixed resistors R1 and R4 and the variable resistors R2 and R3, respectively.

Thus, when the user attaches two feet, the right shoe 200A and the left shoe 200B are electrically connected through metal protrusions 601 formed on the respective side surfaces, and the smart shoe 200 is connected to the whitestone The user's weight is measured through the bridge circuit.

9A and 9B are views for explaining a waterproof structure of an electrode included in a smart shoe according to an embodiment of the present invention.

An electrode may be formed on the side surface of the smart shoe 200 so that the load cells 301 may be connected to each other to form a Wheatstone bridge circuit. According to one embodiment, the electrode may be a metal protrusion structure. However, the present invention is not limited thereto, and the electrodes can be implemented in various types of structures as long as current can flow.

9A shows a metal protrusion 601 formed on the surface of the smart shoe 200. Fig. Electrodes are connected through metal protrusions 601 formed on the side surface of the smart shoe 200 by the action of attaching the feet so that the four load cell modules 400 are connected to form a Wheatstone bridge circuit. Accordingly, the metal protrusion 601 must be formed in a protruding structure on the surface of the smart shoe 200, as shown in Fig. 9A. Due to this characteristic, the metal protrusion 601 can be corroded by external moisture.

The smart shoe 200 includes a load cell module 400 and a control module 500. The load cell module 400 and the control module 500 are electrically connected to the metal protrusion 601. Therefore, moisture seeping through the metal protrusion 601 can be transmitted.

9B shows the waterproof structure of the metal protrusion.

The metal protrusion 601 is required to have a waterproof function against external moisture such as sweat and rain due to the characteristics of the metal protrusion 601 formed on the surface of the smart shoe 200. To this end, the metal protrusion 601 may have an electrode packaging structure for waterproofing. Specifically, the surface of the metal protrusion 601 can be covered with a thin layer of gold by gold plating, whereby corrosion due to external moisture can be prevented.

The load cell module 400 and the control module 500 must be disconnected from the moisture impregnated through the metal protrusion 601 due to the characteristics of passing current therethrough. To this end, the smart shoe 200 may include a waterproof layer 910. The waterproof layer 910 may be made of an impermeable material such as rubber, which does not transmit moisture. The waterproof layer 910 is inserted between the metal protrusion 601 and the sole 220 to block the sole 220 from external moisture. Thus, the waterproof function of the PCB board 920 with the load cell module 400 mounted in the sole 200 can be performed.

FIGS. 10A to 10D illustrate operations for performing various functions using smart shoes according to an embodiment of the present invention.

The function performed by the smart shoe 200 may vary depending on whether the control module 500 is included in one shoe or both shoe parts constituting the smart shoe 200. [ In addition, the function performed by the smart shoe 200 varies depending on whether the user wearing the smart shoe 200 puts the foot on or off.

10A shows a case where the control module 500 is included in only one of the shoes, and the user does not collect both feet. In Fig. 10A, the control module 500 is included only in the right shoe 200A.

In Fig. 10A, the right shoe 200A and the left shoe 200B are not connected. Therefore, current can not flow through the metal protrusion 601, so that the load cell 301 included in the right shoe 200A and the left shoe 200B is not connected, so that a Wheatstone bridge circuit is not formed.

In this case, the smart shoe 200 can not measure the weight of the user.

However, the right shoe 200A including the control module 500 can measure the pressure magnitude and the pressure change amount applied to the right shoe 200A.

10B shows a case where the control module 500 is included in only one of the shoes, and the user collects both feet. In Fig. 10B, the control module 500 is included only in the right shoe 200A.

In Fig. 10B, the right shoe 200A and the left shoe 200B are connected. Accordingly, a current flows through the metal protrusion 601, whereby the right shoe 200A and the load cell 301 included in the left shoe 200B are connected to form a Wheatstone bridge circuit.

In this case, the smart shoe 200 can accurately measure the weight of the user. In addition, the smart shoe 200 can measure the weight of the object held by the user. Furthermore, the smart shoe 200 can estimate the amount of food and the amount of food ingested based on the measured change in body weight, and determine the dietary and calorie intake based on the predicted amount.

FIG. 10C shows a case where the control module 500 is included in both shoes, and the user does not collect both feet.

In Fig. 10C, the right shoe 200A and the left shoe 200B are not connected. Therefore, current can not flow through the metal protrusion 601, so that the load cell 301 included in the right shoe 200A and the left shoe 200B is not connected, so that a Wheatstone bridge circuit is not formed.

In this case, the smart shoe 200 can analyze the distribution of the force applied to the both sole by measuring the distribution of the force in the load cell 301 included in each shoe. Based on this, the fall prediction, the spinal musculoskeletal disease prediction , Recovery and rehabilitation monitoring, and so on. In addition, the smart shoe 200 can monitor whether daily activities are recorded, or whether a doctor's exercise prescription is performed after surgery or treatment.

However, the smart shoe 200 can not measure the weight of the user.

FIG. 10D shows a case where the control module 500 is included in both shoes, and the user collects both feet.

In Fig. 10D, the right shoe 200A and the left shoe 200B are connected. Accordingly, a current flows through the metal protrusion 601, whereby the right shoe 200A and the load cell 301 included in the left shoe 200B are connected to form a Wheatstone bridge circuit.

In this case, as described with reference to FIG. 10C, the smart shoe 200 can determine the distribution of the force applied to each of the right or left foot, and perform various monitoring and functions based on the distribution.

In addition, the smart shoe 200 can accurately measure the weight of the user.

11 is an example of a weight measurement operation using a smart shoe according to an embodiment of the present invention.

The smart shoe 200 can automatically measure the user's weight and upload it to the mobile terminal 100. [ In this case, the smart shoe 200 can measure the user's body weight at predetermined time intervals or in real time.

The metal protrusions 601 formed on the side surfaces of the shoes 200A and 200B are brought into contact with each other by the operation of attaching the shoes 200A and 200B as shown in Fig. In this case, a current flows through the metal protrusion 601 serving as an electrode, whereby the load cells 301 included in the shoes 200A and 200B are connected to a single circuit. The load cells 301 are connected to form a Wheatstone bridge circuit. Accordingly, the smart shoe 200 measures the weight of the user using the Wheatstone bridge circuit.

When obtaining the body weight measurement value, the smart shoe 200 can perform BLE communication with the mobile terminal 100 to transmit the body weight measurement value.

The mobile terminal 100 may display a weight measurement value on the smart shoe application screen 1100. [

On the other hand, the smart shoe application is a smart shoe application which is a smart shoe application that is linked to the mobile terminal 100 and the smart shoe 200, and that is based on the data measured by the smart shoe 200, And may be an application that performs management.

12 is a view illustrating an example of providing a weight measurement guide in a smart shoe according to an embodiment of the present invention.

The smart shoe 200 can provide an attitude guide for accurate weight measurement. The principle of measuring the weight of the smart shoe 200 is similar to that of the general scale 300, but the specific measuring method is different from the measuring method of the weight scale. That is, in order to measure the weight, the user must attach both feet while wearing the smart shoes 200. Since such a measurement method may not be familiar to the user, the smart shoe 200 may provide a weight measurement guide for informing the user of the measurement method.

The weight measurement guide provided by the smart shoe 200 may be displayed through the mobile terminal 100. To this end, the smart shoe 200 performs pairing by the BLE communication with the user's mobile terminal 100, and performs BLE communication with the paired mobile terminal 100. [

According to an embodiment, the smart shoe 200 may provide a direct weight measurement guide. That is, when the smart shoe 200 includes the display unit 151, the smart shoe 200 may provide a weight measurement guide in the form of a character or an image on the display unit 151. Alternatively, when the smart shoe 200 includes the sound output unit 152, the smart shoe 200 may output the weight measurement guide in a voice form.

Referring to FIG. 12, unique information of the smart shoe 200 to be paired with the mobile terminal 100 is input to the mobile terminal 100. For example, the unique information may be a unique number of the mobile terminal 100, that is, a serial number assigned when the mobile terminal 100 is manufactured. In FIG. 12, it is assumed that the unique information is a unique number, but the present invention is not limited thereto. The unique information may include various types of information that can identify the mobile terminal 100 such as an IP address assigned to the mobile terminal 100.

The pairing between the smart shoe 200 and the mobile terminal 100 may be performed only at the time of initial connection or at each connection according to the embodiment.

The smart shoe 200 displays the accurate weight measurement method on the paired mobile terminal 100.

Then, when the mobile terminal 100 receives the weight measurement signal, the smart shoe 200 measures the weight of the user and displays the measured weight value on the mobile terminal 100.

Figure 13 shows another example of providing a weight measurement guide in a smart shoe according to an embodiment of the present invention.

The smart shoe 200 can provide a posture correction guide for correct weight measurement. According to the principle of measuring the weight of the smart shoes 200, the smart shoes 200 need to be positioned on a flat surface so that the weight can be accurately measured. Thus, if the smart shoe 200 is not in the correct position, i. E. If there is an imbalance in the force applied to the load cell 310, the smart shoe 200 will move to a flat position and provide a guide to measure, If you do, you can measure your weight again.

Referring to FIG. 13, an attitude guide for accurate body weight measurement is displayed on the screen of the mobile terminal 100 paired with the smart shoe 200. In response to the input signal from the user, the smart shoe 200 starts measuring the weight.

The smart shoe 200 senses the current state of the smart shoe 200 and determines if the smart shoe 200 can perform the correct weight measurement from it.

If it is determined that the correct weight measurement can not be performed, the smart shoe 200 displays information on the smart shoe 200 on the mobile terminal 100, informs the user, and displays the posture correction guide on the screen of the mobile terminal 100. In this case, the smart shoe 200 may display an image representing the user on the screen, and may reflect the current position of the user on the image so that the user can easily recognize the current state of the smart shoe 200 . For example, if it is determined that the smart shoes 200 are currently placed at an angle, an image representing the user is displayed by tilting as shown in FIG.

The smart shoe 200 measures the weight of the user and displays the measured weight on the mobile terminal 100. The smart shoe 200 measures the weight of the user, do.

14 is a view illustrating a screen displayed on a mobile terminal paired with a smart shoe according to an embodiment of the present invention.

When the smart shoes 200 and the mobile terminal 100 are connected to each other by performing pairing, the mobile terminal 100 may execute the smart shoes app based on the data measured by the smart shoes 200. The SmartShows app can provide health management functions including weight management, diet management, exercise management, and posture correction.

When the smart shoes app is executed, the main screen 1410 as shown in Fig. 14 is displayed for the first time.

The main screen 1410 may include user information 1411, a target weight 1412, a current weight 1413, an amount of exercise 1414, an amount of food eaten 1415, and the like.

User information 1411 includes the user's name, age, and gender.

The target weight 1412 is the target weight set by the user.

The current weight 1413 is the current weight of the user measured by the smart shoe 200. The smart shoe 200 can measure the weight of the user at predetermined intervals and update it in real time. Therefore, the last measured value based on the current point of time can be regarded as the current weight of the user 1413.

The amount of exercise 1414 is the amount of exercise performed by the user during a predetermined period. The exercise amount 1414 may include a target exercise amount for a predetermined period and exercise amount data performed for a predetermined period, and may be displayed for a specific exercise type. Here, the predetermined period may be set in units of time, day, month, year, and the like. 14, the momentum 1414 includes a target distance for one day and a distance for a day to walk.

The amount of food 1415 is the weight of the food consumed by the user for a predetermined period. In FIG. 14, the amount of food 1415 consumed can be calculated by dividing the weight of the food consumed by the user during the day into morning, lunch, and evening.

The image 1416 representing the user reflects the current state of the user. The image 1416 may be displayed differently corresponding to the user's current weight 1413 or the amount of food 1415 consumed.

The smart shoes app configured as described above can present a guide to reach the target weight 1412 to the user. Specifically, when the target weight 1412 is set, the smart shoes app measures the current weight 1413 of the user, analyzes the target weight 1412 and the current weight 1413, and then reaches the target weight 1412 The amount of exercise 1414 is automatically set. For example, Fig. 14 sets Today's target distance, i.e., the target distance the user must walk for a day to reach the target weight 1412. [

When the target weight 1412 or the current weight 1413 is changed, the smart shoe 200 can change the amount of exercise 1414 accordingly.

In addition, in order to achieve the target weight 1412, the amount of food 1415 as well as the amount of exercise 1414 should be considered. Accordingly, the smart shoe 200 may analyze the eaten food quantity 1415 and change the quantity of exercise 1414 in response to the eaten food quantity 1415. [

Hereinafter, various health care functions, applications, and user experiences (UX) that can be measured and provided based on the weight of the smart shoe 200 will be described in detail.

15A to 15C illustrate an example of providing a guide to health care in smart shoes according to an embodiment of the present invention.

The smart shoe 200 may provide a guide to health care differently depending on whether or not the user performed an operation to attach a foot.

The smart shoe 200 can measure the user's weight only when the user wearing the smart shoe 200 collects the two feet and connects the two shoes 200A and 200B. Thus, depending on whether the two shoes 200A, 200B are connected or not, whether or not the smart shoes 200 can obtain weight information is different. Depending on the presence or absence of weight information, the guide to health care provided by the smart shoes 200 may vary.

15A is a main screen of a smart shoe app displayed when there is no action to attach a foot. In this case, the smart shoe 200 can not measure the weight of the user. Accordingly, the smart shoe 200 provides a recommended walking course 1511 instead of the current weight 1413. In this case, the recommended walking course 1511 may be changed corresponding to the amount of exercise 1414. [ In accordance with an embodiment, the smart shoe 200 may predict and display the expected weight instead of the current weight 1413. In this case, the expected body weight can be changed corresponding to the exercise amount 1414. [

On the other hand, in FIG. 15A, when an input signal for selecting the target weight 1412 is sensed, the smart shoes 200 may present a guide for achieving the target weight 1412. [

Figs. 15B and 15C show the guide for achieving the target weight 1412. Fig. The smart shoes 200 may provide a guide for achieving the target weight 1412. As shown in Figs. 15B and 15C, the guide for achieving the target weight 1412 may include items such as a target daily distance, a target weight, an expected achievement date, and the like. These items may be changed corresponding to the input signal from the user. Since each item is interlocked with each other, when one item is changed, another item can be changed correspondingly.

In Fig. 15B, the target distance for one day is changed from 10 Km to 12 Km corresponding to the input signal from the user. As a result, the predicted achievement date of the target weight is expected to be accelerated. The expected date of completion was changed from August 10, 2016 to June 18, 2016.

In Fig. 15C, the smart shoe 200 measures that the distance walked today is 2 Km. In this case, the smart shoe 200 judges that the user has walked less than the target distance per day, and delays the expected achievement date by reflecting this. The expected date of the change was changed from August 10, 2016 to August 12, 2016. In addition, the smart shoe 200 can increase the target distance per day by reflecting the insufficient amount of exercise. In FIG. 15C, the target daily distance is changed from 10 km to 11 km.

As such, the smart shoe 200 measures the user's momentum and provides feedback on the amount of movement that is exceeded or exceeded. Further, it is possible to reset the user-set health care target by reflecting the measured value of the exercise amount, or to provide the user with a guide for achieving the set health care goal.

15A to 15C, the smart shoe 200 can not measure the weight of the user because the user does not put a foot on the foot. In this case, the smart shoe 200 can predict and display the expected weight. Such an expected weight can be changed correspondingly when the set value of another item is changed. For example, if the user increases the target distance per day, the expected weight decreases, and the expected weight is changed correspondingly as the distance walked today is less than or exceeds the daily target distance.

16 illustrates an example of providing a guide for reaching a target weight in a smart shoe according to an embodiment of the present invention.

The smart shoe 200 may provide a guide for reaching a target weight in accordance with the schedule of the user. Specifically, the smart shoe 200 may calculate a momentum to be additionally performed to reach a target weight, and provide a guide to exercise time and exercise method according to a schedule. For this purpose, the smart shoe 200 may interoperate with the schedule management app executed by the mobile terminal 100. [
