Meanwhile, the sensing unit 140 senses at least one of information within the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a sensing signal corresponding thereto. Based on these sensing signals, the controller 180 may control driving or operation of the mobile terminal 100 or may process data related to applications installed in the mobile terminal 100, perform functions or operations. 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 or absence of an object approaching a predetermined detection surface or an object existing nearby without mechanical contact by using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner area of the mobile terminal covered by the touch screen described above or in the vicinity of 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 capacitance type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. If the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of a conductive object as a change in electric field according to the proximity of the object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, an action of approaching a touch screen without contacting an object to recognize that the object is located on the touch screen is referred to as a "proximity touch", and the touch An act of actually touching an object on a screen is called a "contact touch". The location at which an object is proximity-touched on the touch screen means a location at which the object corresponds vertically to the touch screen when the object is proximity-touched. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) there is. Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and proximity touch pattern detected through the proximity sensor 141, and furthermore, visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) depending on whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor detects a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. detect

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or capacitance generated in a specific part into an electrical input signal. The touch sensor may be configured to detect a location, area, pressure upon touch, capacitance upon touch, and the like, at which a touch object that applies a touch to the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

As such, 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 then transmits corresponding data to the controller 180. Thus, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or the same control according to the type of the touch object that touches the touch screen (or a touch key provided other than the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to an operating state of the mobile terminal 100 or an application program currently being executed.

On the other hand, the touch sensor and proximity sensor described above are independently or combined, short (or tap) touch, long touch, multi-touch, drag touch on the touch screen ), flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. Touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generating source through information detected by the optical sensor and the plurality of ultrasonic sensors. The position of the wave generating source can be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the location of the wave generating source may be calculated by using light as a reference signal and a time difference between the arrival time of ultrasonic waves.

Meanwhile, looking at the configuration of the input unit 120, the camera 121 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. A photo sensor may be stacked on a display device, and the photo sensor is configured to scan a motion of a sensing target close to the touch screen. More specifically, the photo sensor scans the content placed on the photo sensor by mounting photo diodes and transistors (TRs) in rows/columns and using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing object according to the change in light, and through this, the location information of the sensing object can be obtained.

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 in the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to such execution screen information. .

Also, the display unit 151 may be configured as a 3D display unit that displays a 3D image.

A 3D display method such as a stereoscopic method (glasses method), an auto stereoscopic method (non-glasses method), or a projection method (holographic method) may be applied to the 3D display unit.

In general, a 3D stereoscopic image is composed of a left image (image for the left eye) and a right image (image for the right eye). According to the method of combining the left and right images into a 3D stereoscopic image, top-down method in which the left and right images are arranged up and down in one frame, left and right images in one frame L-to-R (left-to-right, side by side) method for arranging left and right images, checker board method for arranging pieces of left and right images in tile form, and left and right images in units of columns Alternatively, it is divided into an interlaced method that alternately arranges rows, and a time-sequential, frame-by-frame method that alternately displays a left image and a right image by time.

Also, the 3D thumbnail image may be generated as a single image by generating left and right image thumbnails from the left and right images of the original image frame, respectively, and combining them. In general, a thumbnail refers to a reduced image or a reduced still image. The generated left and right image thumbnails are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax between the left and right images, thereby representing a three-dimensional sense of space.

A left image and a right image necessary for implementing a 3D stereoscopic image may be displayed on a stereoscopic display unit by a stereoscopic processing unit. The stereoscopic processing unit receives 3D images (images at a reference point and images at an extended point of view) and sets left and right images therefrom, or receives 2D images and converts them into left and right images.

The audio 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, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like. The sound output unit 152 also outputs sound signals related to functions performed by the mobile terminal 100 (eg, call signal reception sound, message reception sound, etc.). The sound output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that a user can feel. A representative example of the tactile effect generated by the haptic module 153 may be vibration. The strength and pattern of the vibration generated by the haptic module 153 may be controlled by a user's selection or a setting of a controller. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output them.

In addition to vibration, the haptic module 153 responds to stimuli such as an array of pins that move vertically with respect to the contact skin surface, air blowing force or suction force through a nozzle or suction port, rubbing against the skin surface, electrode contact, and electrostatic force. It is possible to generate various tactile effects, such as the effect of heat absorption and the effect of reproducing the feeling of coolness and warmth using an element capable of absorbing heat or generating heat.

The haptic module 153 not only transmits a tactile effect through direct contact, but also can be implemented so that a user can feel a tactile effect through a muscle sense such as a finger or an arm. Two or more haptic modules 153 may be provided according to the configuration of the mobile terminal 100 .

The light output unit 154 outputs a signal for notifying occurrence of an event using light from a light source of the mobile terminal 100 . Examples of events occurring in the mobile terminal 100 may include message reception, call signal reception, missed calls, alarms, schedule notifications, e-mail reception, and information reception through applications.

The controller 240 checks the amount of power stored in the battery unit 230 in response to the received power request signal.

If the amount of stored power is too small, it may be more desirable to operate the wearable device 200 itself with the power rather than to transmit the power to the mobile device 100 .

When the amount of power is less than the preset first amount of power, the controller 240 transmits a power transmission impossible message to the mobile device 100 . Here, the first amount of power may be 50% of the total amount of chargeable power of the battery unit. Here, the first amount of power, the second amount of power, and the third amount of power are just examples, and the scope of the present invention is not limited thereto.

When the amount of stored power is equal to or greater than a predetermined power, it is preferable to transmit the excess power to the mobile device 100 . This is because the amount of power of the wearable device 200 is sufficient. However, since power consumption may be high when the power transmission rate is increased, the power transmission rate may be normal.

When the amount of power is equal to or greater than the first amount of power and less than the second amount of power, the controller 240 transmits the excess power to the mobile device 100 at the first transmission rate. Here, the first amount of power may be 50% of the total amount of chargeable power of the battery unit, and the second amount of power may be 70% of the total amount of chargeable power of the battery unit.

Here, the remaining power is the amount of power obtained by subtracting the first amount of power from the total amount of chargeable power. The control unit 240 transmits a power transmission impossible message to the mobile device 100 when the amount of power is equal to or less than the first amount of power. This is because the excess power is zero if the amount of power is equal to or less than the first amount of power.

When the amount of stored power exceeds a predetermined amount and is sufficient, it is preferable to transmit the excess power to the mobile device 100 at a high speed. This is because the amount of power of the wearable device 200 is sufficient. In addition, even if power consumption is high by increasing the power transmission rate, since the amount of power is sufficient, the power transmission rate can be high.

When the amount of power is greater than the second power value and less than or equal to the third power value, the controller 240 transmits the excess power to the mobile device 100 at the second transmission rate. When the amount of power is equal to or greater than the first amount of power and less than the second amount of power, the controller 240 transmits the excess power to the mobile device 100 at the first transmission rate. The second transmission rate is faster than the first transmission rate.

Here, the second amount of power may be 70% of the total amount of chargeable power of the battery unit, and the third amount of power may be 100% of the total amount of chargeable power of the battery unit.

Here, the remaining power is the amount of power obtained by subtracting the first amount of power from the total amount of chargeable power. The control unit 240 transmits a power transmission impossible message to the mobile device 100 when the amount of power is equal to or less than the first amount of power. This is because the excess power is zero if the amount of power is equal to or less than the first amount of power.

According to the present invention, it is possible to check the amount of power stored in the battery unit and transmit excess power of the wearable device differently to the mobile device according to the amount of stored power, so that the power can be efficiently distributed to the mobile device, thereby improving user convenience. there is.

7 is a diagram illustrating generation of triboelectricity in a wearable device by foot impact according to an embodiment of the present invention.

Referring to FIG. 7 , when a user walks or runs while wearing the wearable device 200, triboelectricity is generated, and the generated triboelectricity is transmitted to the battery unit 230 included in the wearable device 200. Saved.

8 is a diagram illustrating a process of storing generated triboelectricity in a battery according to an embodiment of the present invention.

Referring to FIG. 8 , the wearable device 200 includes a transformer 242 , a rectifier 244 , and a capacitance 246 .

The transformer 242 increases or decreases the AC voltage using electromagnetic mutual induction. Transformer 242 lowers the generated triboelectric power to the 5V range.

The rectifier 244 converts alternating current into direct current. Since the triboelectric generated is alternating current, the rectifier 244 converts it into direct current.

Capacitance 246 cancels rectified triboelectric noise. There is a surge part in the triboelectric, and the capacitance 246 removes the surge part, that is, the noise component.

Therefore, the control unit 240 undergoes a transforming process for the generated triboelectric power through the transformer 242, rectifies the triboelectric power that has undergone the transforming process through the rectifier 244, and converts the noise of the rectified triboelectric power to the capacitance 246 and the triboelectricity from which the noise has been removed is stored in the battery unit 230.

9 is a diagram illustrating that an impulse is generated by a step in a wearable device according to an embodiment of the present invention.

Referring to FIG. 9 , the wearable device 200 further includes a sensor unit 260 that senses the amount of impact generated by triboelectricity.

In FIG. 9 , the x-axis means time, and the y-axis means the amount of impact generated when the user walks.

If the amount of impulse sensed through the sensor unit 260 is greater than or equal to a predetermined value, the control unit 260 determines that the wakeup state is in the wakeup state, and if the amount of impulse sensed is less than or equal to the predetermined value, it is determined that the state is not in the wakeup state.

For example, if the amount of impulse sensed through the sensor unit 260 is greater than or equal to a first reference value, the controller 240 determines that the wearable device is in a wake-up state, and if the amount of impulse sensed is less than the first reference value, the controller 260 determines that the wearable device is in a sleep state.

According to the present invention, when the user is in a stationary state, since the amount of impact is hardly sensed, the controller 240 determines that the user is in a sleep state. When the user starts to walk, the impulse is sensed, and if the sensed impulse is greater than or equal to a first reference value, the controller 240 determines that the wearable device is in a wakeup state. Therefore, since it is possible to determine whether the wearable device is in an on state based on the user's movement, user convenience can be improved.

According to one embodiment of the present invention, it is possible to distinguish whether the user is in a walking state or a running state based on the amount of impulse.

Referring to FIG. 9 , when the user is in a stationary state, almost no impact is generated, and when the user is in a walking state, an impulse greater than or equal to a first reference value is generated. When the user is in a running state, it can be seen that an impulse greater than or equal to the second reference value is generated.

The controller 240 determines a walking state when the sensed impulse is equal to or greater than a first reference value, and determines a running state when the sensed impulse is equal to or greater than a second reference value. Here, the second reference value is greater than the first reference value.

Next, a step count function in which the wearable device counts how many steps a user has taken in a day will be described.

When a user walks, an impact amount over a certain range is transmitted to the wearable device by the user's walking. Therefore, by counting the impulse, you can find out how many steps you have taken in a day.

If the sensed impulse amount is greater than or equal to a predetermined value, the controller counts it and adds the counted number of times to calculate a step count.

According to the prior art, step counting was performed using a pressure sensor. However, according to the present invention, step counting can be performed based on the amount of impact and a pressure sensor is not required, so the effect of eliminating parts is recognized.

Next, sensing the balance of the right foot and the left foot based on the amount of impact will be described.

Referring to FIG. 9 , the upper portion of the x-axis represents the amount of impact generated from the right foot 910, and the lower portion represents the amount of impact generated from the left foot 920.

When a user walks, the balance of pressure applied to the right foot and left foot is important. The ideal case is when the balance between the right foot and the left foot is 50:50, and it is generally considered stable when the balance is 55:45 or 45:55.

In addition, when the pressure range of the right foot is 45 to 55 unit pressure and the pressure range of the left foot is 45 to 55 unit pressure, it is determined to be stable.

However, if it is 70:30, it is judged to be medically abnormal. In this case, since there is a problem in the user's walking habit, the user can recognize that there is a problem in his or her walking habit and take action.

The controller 240 may sense the balance between the right foot and the left foot based on the sensed impulse. The controller 240 calculates the total pressure of the right foot by integrating the impulse sensed by the right foot 910 . In addition, the controller 240 calculates the total pressure of the left foot by integrating the impulse sensed by the left foot 920 . The controller 240 compares the total pressure of the right foot and the total pressure of the left foot, and then calculates the balance between the right foot and the left foot.

According to the prior art, when sensing the balance of the right foot and the left foot, the sensing was performed using a pressure sensor. According to the present invention, since the balance of the foot can be sensed based on the amount of impact and a pressure sensor is not required, the effect of eliminating parts is recognized.

10 is a diagram illustrating states of a right foot and a left foot when a user wearing a wearable device according to an embodiment of the present invention walks.

Referring to FIG. 10 , a gait cycle indicating that a user 10 wearing the wearable device 200 walks at a regular interval is illustrated. In a gait cycle, 0% means that a step is initiated, and 100% means that a step of one cycle has been completed.

The double support 1001 means a state in which both feet touch the ground, and the single support 1002 means a state in which one foot touches the ground and the other foot touches the ground.

In the case of the left foot, the stance 1050 means a state where the left foot touches the ground, and the swing 1040 means a state where the left foot lands on the ground. In the case of the right foot, stance 1010 means a state where the right foot touches the ground, and swing 1020 means a state where the right foot lands on the ground.

Referring to FIG. 10 , the controller 240 determines that a walking state is present when there exists a section 1030 in which a stance section 1050 in which the left foot touches the ground and a stance section 1010 in which the right foot touches the ground overlap during the gait cycle. .

Here, the walking state means a state in which the user is walking. Here, the stance section 1030 is a double support state.

That is, the controller 240 determines that the user is in a walking state when the single support 1002 and the double support 1001 exist during the walking cycle.

The controller 240 determines that a running state is present if there is no overlapping section 1030 between the stance section 1050 in which the left foot touches the ground and the stance section 1010 in which the right foot touches the ground during the gait cycle.

If the stance section 1030 in which the feet touch the ground does not exist simultaneously between the left foot and the right foot during the gait cycle, it is determined as a running state. Here, the running state means a state in which the user is running.

That is, the controller 240 determines that the user is in a running state when there is only a single support and no double support during the gait cycle.

According to the present invention, it is possible to easily determine whether a user is in a walking state or a running state based on a stance and a swing state during a gait cycle, thereby improving user convenience.

11 is a diagram illustrating a screen of a mobile device connected to a wearable device according to an embodiment of the present invention.

Referring to FIG. 11 , the total amount of activity, power walking, and slow steps are shown, and the number of steps, moving distance, and calories consumed measured using a specific application from the start time to the present time are output.

The controller 240 generates a control signal for distinguishing between power walking and slow walking based on the sensed impulse, and transmits the generated control signal to the external mobile device 100 .

If the amount of impulse sensed within a predetermined time is greater than or equal to the first reference value and less than the second reference value, the controller 240 determines that walking is slow, and if the amount of impulse sensed within the predetermined time is greater than or equal to the second reference value, the controller 240 determines that walking is power walking. judge by Here, the first reference value is greater than the second reference value.

12 is a diagram illustrating pressure from a user's foot when a user wears a wearable device according to an embodiment of the present invention.

Referring to FIG. 12 , the user's foot may be divided into a forefoot portion 1210 and a rear foot portion 1220 .

The forefoot portion 1210 is a place where the forces of compression, shear, and bending are applied. Here, shear force is explained. When a pair of forces are applied in opposite directions parallel to a certain section of an object, the object slides along that plane and is cut. This is called shear action, and the force exerted by this action is called shear force.

In the case of the forefoot portion 1210, compression force, shear force, and bending force act. In contrast, in the case of the hindfoot portion 1220, only compression is applied. Therefore, in the case of the forefoot ( 1210 ), it is difficult to set an appropriate pressure threshold because individual weights, walking habits, and walking patterns are all different. On the other hand, in the case of the rear foot 1220, since only compression is applied, a suitable pressure threshold may be set.

According to the present invention, the wearable device 200 is installed on the rear foot portion 1220 of the user's foot. In this case, since an appropriate pressure threshold can be set and excessive pressure applied to the charging body can be prevented, user convenience can be improved.

Referring to FIG. 13 , the x-axis illustrates female, male, walking, and running, and the y-axis illustrates the pressure level in each case. The pressure magnitude represents a relative pressure unit. Here, the unit of pressure may be kilopascals.

For women, the change in magnitude of pressure can be between 50 and 90 units of pressure. Here, unit pressure is omitted.

For males, the change in pressure magnitude can be between 90 and 140.

In the case of walking, the magnitude change of the pressure may be 80 to 120.

In the case of running, the change in magnitude of the pressure may be 280 to 320.

According to an embodiment of the present invention, the pressure limit for contacting the first electrified body and the second electrified body may be set to a walking condition of a woman having the lowest weight among several sample values. In the present invention, it may be 50 unit pressure.

In addition, the first member and the second member can be inserted between the front case and the rear case, or an elastic body can be inserted between the front case and the charging body. In this case, when a heavy person wears the wearable device and excessive pressure is transmitted to the wearable device, the pressure is structurally blocked to prevent unnecessary pressure from being transmitted to the wearable device, thereby preventing damage to the charging body. can

According to the present invention, since the O-ring 1410, the battery cover 1420, the coin cell battery 1430, and the battery circuit 1440 can all be eliminated, the number of parts can be reduced. In addition, since the wearable device can be implemented simply by combining the front case 201 and the rear case 202, the product size can be freely adjusted and various designs can be made.

In addition, in order to prevent water from penetrating into a battery cell in the prior art, an O-ring 1410 and a battery cover 1420 are essentially required. However, in the case of the present invention, since the O-ring 1410 and the battery cover 1420 can overcome a waterproof and moisture-proof environment, user convenience can be improved.
