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.

7, when the multimedia file is being reproduced while the earphone is mounted on the interface unit 160 of the mobile terminal 100 interlocked with the smart watch 200, the mobile terminal 100 determines whether the earphone is connected Information on whether the multimedia file is reproduced or not is transmitted to the smart watch 200.
The smart watch 200 receives information on whether or not the earphone is connected and whether or not the multimedia file is reproduced through the short distance communication module 214. The smart watch 200 enters a sound signal recognition mode for sensing a dangerous signal among various sound signals generated from the outside, when recognizing the fact that the earphone is installed and the multimedia file is reproduced through the received information.
When an external sound signal is generated in the acoustic signal recognition mode, the smart watch 200 inputs the sound signal through the first and second microphones 222a and 222b arranged in the left / right area of the main body 201 in real time The external acoustic signal is analyzed. At this time, the smart watch 200 can analyze the frequency characteristics of the external acoustic signals inputted through the first and second microphones 222a and 222b, and can detect the type, strength, direction, and risk of the corresponding acoustic signal .
If the sound signal input through the first and second microphones is a 'sound signal preset as a danger signal', the smart watch 200 may generate a tactile alarm And outputs a signal.
For example, the smart watch 200 may output vibration through a haptic module (not shown) provided in the main body 201, output an electrical stimulus through the nerve stimulation part 231 provided on the back surface of the main body 201 , A stimulus for tightening the wrist through a band pulling part 232 provided on one side of the main body 201, or a combination of these methods can be output. At this time, the smart watch 200 can adjust the strength of a stimulus applied to the wrist according to the intensity and the risk of the detected sound signal. Accordingly, the user wearing the earphone can intuitively recognize the present dangerous situation based on the tactile alarm information provided in the smart watch 200. [
FIG. 8 is a diagram for explaining the operation of the smart watch for stopping the reproduction of a multimedia file through a simple touch input when receiving a predetermined voice signal.
8, when the earphone is mounted on the interface unit 160 of the mobile terminal 100 interlocked with the smart watch 200 or the multimedia file is being reproduced while the Bluetooth earphone is wirelessly connected, the mobile terminal 100 Transmits information on whether or not the earphone is connected and whether or not the multimedia file is reproduced to the smart watch 200.
The smart watch 200 receives information on whether or not the earphone is connected and whether or not the multimedia file is reproduced through the short distance communication module 214. The smart watch 200 enters a voice recognition mode for sensing a predetermined voice signal among various sound signals generated from the outside.
In addition, the smart watch 200 may display an indicator 820 in an area of the clock screen 810 to indicate that the multimedia file is being received through the earphone.
In this voice recognition mode, when an external acoustic signal is generated, the smart watch 200 is input in real time through the first and second microphones 222a and 222b arranged in the left / right area of the main body 201 Analyze the external acoustic signal. At this time, the smart watch 200 can analyze the frequency characteristics of the external acoustic signals input through the first and second microphones 222a and 222b, and detect the type, strength, direction, meaning, etc. of the corresponding acoustic signal .
When the sound signal input through the first and second microphones is a 'preset sound signal', the smart watch 280 generates a tactile feedback signal to promptly inform the user that an event corresponding to the sound signal is occurring And outputs an alarm signal. Here, it is assumed that the preset audio signal is a voice signal that broadcasts a preset arrival station.
For example, the smart watch 200 may output vibration through a haptic module (not shown) provided in the main body 201, output an electrical stimulus through the nerve stimulation part 231 provided on the back surface of the main body 201 , A stimulus for tightening the wrist through a band pulling part 232 provided on one side of the main body 201, or a combination of these methods can be output. Accordingly, the user wearing the earphone can intuitively recognize the fact that the subway announcement is output based on the tactile alarm information provided in the smart watch 200.
When the subway announcement is detected, the smart watch 200 may display an indicator 830 on the display unit 251 to select whether to stop playback of the multimedia file being executed in the mobile terminal 100.
When the indicator 830 is touched, the smart watch 200 transmits a control signal to the mobile terminal 100 to stop the multimedia file being played through the earphone. That is, when a voice signal for guiding her own arrival station is detected while listening to music through the earphone, a user wearing the earphone can immediately recognize the occurrence of the event through a predetermined alarm signal, It is possible to stop the music currently being played through a simple touch input. As a result, the user wearing the earphone can easily hear the subway broadcasting that guides the next arrival station.
