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 an object existing in the vicinity of the detection surface without mechanical contact using an 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. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

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 senses 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, do.

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, etc. of a touch object to be touched on the touch screen 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, which touches 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 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera 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 .

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

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.

For example, the region where the third electrode terminal 230a is formed is divided to form two electrode terminals, or the region where the second and third electrode terminals 220a and 230a are formed is divided to form three electrode terminals .

Hereinafter, a method of using the multi-pole plug 200 according to an embodiment of the present invention will be described.

At least two electrode terminals are added to the multi-pole plug 200, 300, 400 according to an embodiment of the present invention. The two electrode terminals of the multiple electrode terminals may be used as first and second microphone electrode terminals . For example, in the case of a four-pole plug, it is generally composed of an L audio terminal, an R audio terminal, a ground terminal and a communication microphone terminal. In the case of a six-pole plug, two additional microphone terminals can be added.

The first and second microphone electrode terminals may transmit active noise canceling (ANC) information or may transmit first sound information and second sound information, respectively. That is, when the multipolar plug 200 according to the embodiment of the present invention is inserted into the multipolar jack 500, the multipolar plug 200 and the multipolar jack 500 are electrically connected by the connection terminals 471, 472, 473, 474, 475, 476, If the multipolar plug 200 is an earplug used in an earphone, two microphone electrode terminals other than the electrode terminal used in the four-pole plug can be used as the microphone electrode terminal.

The ANC function refers to a function of sensing ambient noise from the first and second microphone electrode terminals and generating a reverse phase signal with respect to ambient noise, thereby canceling ambient noise coming into the ear by a reverse phase signal. As a result, it is possible to listen to music without the influence of noise even in a noisy environment. Two electrode terminals are required for the ANC function.

The first and second microphone electrode terminals may transmit the first acoustic information and the second acoustic information, respectively, thereby recording three-dimensional sounds through the microphone electrode terminals of the left and right channels, respectively. For example, a binaural recording function can be performed.

In addition, two electrode terminals of the plurality of electrode terminals to be added may be electrode terminals for transmitting two kinds of information, that is, heart rate, pulse rate, or body temperature, in order to perform a health care function. At this time, one electrode terminal can transmit information on heart rate, pulse or body temperature, respectively. In order to obtain more accurate body information, at least two pieces of information must be combined. Therefore, in one embodiment of the present invention, information on heart rate, pulse rate, or body temperature is transmitted through two or more electrode terminals.

For example, two electrode terminals may be used to transmit information on heart rate and body temperature to the terminal. If it is connected to a temperature sensor near the user, it monitors the body temperature. If the body temperature is outside the proper temperature, it sends a signal to the warm air system or the cooling system to keep the body temperature at a normal level. A warning message may be sent out to make sure that the wearer has no health problems.

In addition, in one embodiment of the present invention, a remote control function may be performed. To accomplish this, four electrode terminals of the plurality of electrode terminals are connected to the terminals An electrode terminal for transmitting information for stopping reproduction, an electrode terminal for transmitting fast forward information, and an electrode terminal for transmitting rewind information.

The user can conveniently select the playback speed or stop at the time of multimedia device reproduction by such terminals.
