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.

Meanwhile, in another embodiment, the magnetic sensor 310 may check whether the difference between the currently measured magnetic signal and the previously measured magnetic signal exceeds a predetermined threshold.
If it is determined in step 1130 that the measured magnetic signal does not exceed the threshold value, the magnetic sensor 310 does not transmit the measured magnetic signal to the controller 280, and proceeds to step 1120 to continuously measure the magnetic signal .
If it is determined in step 1130 that the measured magnetic signal exceeds the threshold value, the magnetic sensor 310 transmits an interrupt signal to the controller 280 in step S1140. Thereafter, the magnetic sensor 310 transmits the measured magnetic signal to the controller 280 (S1160).
Upon receiving the interrupt signal, the control unit 280 switches the operation mode from the sleep mode to the active mode, and then receives the measurement data related to the magnetic signal from the magnetic sensor 310 (S1150, S1160).
That is, by waking up the control unit 280 through the interrupt signal only when the specific condition is satisfied, battery consumption caused by the control unit 280 always awake can be saved.
The control unit 280 senses a change in the position of the permanent magnet based on the magnetic signal measured through the magnetic sensor 310 (S1170). That is, when the user changes the position of the permanent magnet through the slide operation, the wheel operation, or the flip operation, the controller 280 can sense a change in the position of the permanent magnet based on a change in the magnetic signal.
The control unit 280 performs a predetermined control function corresponding to the detected change of the permanent magnet (S1180). The predetermined control function includes a drag function, a scroll function, a navigation function, a selection function, an execution function, an enlargement / reduction function, a screen switching function, a mode switching function, a volume up / down function, , But is not limited thereto.
In this manner, the magnet control system through the slide operation, the wheel operation, or the flip operation not only allows the user to conveniently operate the smart watch even in the water, but also allows the smart watch to be convenient So that it can be operated.
As described above, according to another embodiment of the present invention, the operation of the smart watch can be easily controlled by utilizing the magnetic sensor mounted on the main body and the permanent magnet mounted on the band.
12 is a diagram illustrating a hardware structure for low power driving in a smart watch according to the present invention.
Referring to FIG. 12 (a), the smart watch 200 may include a controller 280 and a magnetic sensor 1210. The magnetic sensor 1210 may include a control module 1211 and a sensing module 1213.
The sensing module 1213 measures the intensity and direction of the magnetic field generated by the permanent magnet.
The control module 1211 may transmit an interrupt signal to the control unit 280 when the magnetic signal measured through the sensing module 1213 exceeds a threshold value (i.e., a specific condition occurs). The control module 1211 transmits the magnetic signal measured through the sensing module 1213 to the controller 280. [
Upon receiving the interrupt signal, the control unit 280 switches the operation mode from the sleep mode to the active mode, and then receives the magnetic signal from the control module 1211. The control unit 280 can sense whether the smart watch 200 is worn or control the operation of the smart watch 200 based on the received magnetic signal.
As described above, the control unit 280 is woken up through the interrupt signal only when the specific condition is satisfied, so that the battery consumption caused by the control unit 280 always awake can be saved.
12 (b), the smart watch 200 includes a control unit 280, a sensor hub 1220, a magnetic sensor 1230, an acceleration sensor 1240, a gyro sensor 1250, And the like. The sensor hub 1220 may include a control module 1225 for controlling various sensors.
The magnetic sensor 1230 measures the intensity and direction of the magnetic field generated in the permanent magnet.
The control module 1225 can transmit an interrupt signal to the control unit 280 when the magnetic signal measured through the magnetic sensor 1230 exceeds a threshold value (i.e., a specific condition occurs). Then, the control module 1225 transmits the magnetic signal measured through the magnetic sensor 1230 to the control unit 280.
Upon receiving the interrupt signal, the control unit 280 switches the operation mode from the sleep mode to the active mode, and then receives the magnetic signal from the control module 1211. The control unit 280 can sense whether the smart watch 200 is worn or control the operation of the smart watch 200 based on the received magnetic signal.
Similarly, by waking up the control unit 280 through the interrupt signal only when the specific condition is satisfied, the consumption of the battery caused by the control unit 280 always awake can be saved.
