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.

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.

Accordingly, the mobile terminal according to the present invention may include some or all of the configurations described in FIG. 1A, and may further include a tactile output unit 156 as a configuration of the output unit 150 for outputting tactile feedback.
2 is a simplified block diagram illustrating a mobile terminal according to the present invention.
The mobile terminal may include a wireless communication unit 110, an input unit 120, an output unit 150, a memory 170, and a control unit 180.
The wireless communication unit 110 may communicate with the mobile terminal 100 and the wireless communication system or between the mobile terminal 100 and another mobile terminal 100 or between the mobile terminal 100 and the external server, Modules.
The output unit 150 may generate an output related to visual, auditory, tactile, or the like. The output unit 150 may include a touch screen 151 formed integrally with the display unit and the touch sensor in a layer structure or a tactile output unit 156 outputting a tactile sensation.
The touch screen 151 may function as a user input unit 123 for providing an input interface between the mobile terminal 100 and a user and may provide an output interface between the mobile terminal 100 and a user.
The touch output unit 156 outputs various tactile sensations when the touch screen 151 is contacted under the control of the control unit 180. [ The tactile output unit 156 can generate tactile feel such as slippery or rough feeling by generating electric vibration friction on the surface or generating ultrasonic vibration to change the friction coefficient of the surface of the touch screen 151. [ In addition, the tactile output unit 156 outputs a tactile sensation including a substance whose physical shape is deformed according to the driving voltage, for example, Lead Lanthanum Zirconate Titanate (PLZT), or transmits a touch using a battery stimulus and a pin protrusion stimulus It is also possible to include a tactile generation plate. The tactile output unit 156 may include at least one configuration in which the above-mentioned tactile output function provides a tactile output function in various other ways.
The tactile information output through the tactile output section 156 is stored in the memory. The tactile information may include control settings of the tactile output 156 according to the tactile sensation to be output in various tactile output modes.
Figs. 3 and 4 are diagrams for explaining the principle of operation of the tactile output section 156, illustrating the tactile output principle using ultrasonic vibration. When the ultrasonic vibration is applied to the touch screen 151, the frictional force on the surface of the touch screen 151 can be adjusted according to the intensity of the vibration, and a high-pressure air layer can be formed.
3, when an ultrasonic vibration is applied to a specific area of the touch screen 151 in order to output a slippery touch, a high-pressure air layer is formed between the finger and the touch screen 151 by the vibration of the ultrasonic waves. Thus, the tactile sensation touching the slippery surface can be transmitted to the user who touched the tactile output section 156. [
Referring to FIG. 4, when a rugged or coarse tactile sensation is to be output, a high friction region H and a low friction region L can be repetitively generated at a high speed by ultrasonic vibration. Thus, the user who touched the tactile output unit 156 can transmit a tactile feel as if touching a rugged or rough surface.
As described above, in addition to the technique using ultrasonic vibration, it is possible to generate static electricity or generate vibration on the touch screen 151 to transmit a specific touch. It is also possible to provide a tactile output device whose physical shape changes on the touch screen 151.

For example, information such as an ultrasonic vibration setting for outputting a slippery touch, an ultrasonic vibration setting for outputting a rough touch, and the like can be stored.
Thereafter, the control unit 180 determines whether the tactile output mode is entered (S120). The tactile output mode in which the tactile sensation is output can be set by the user or set at the time of designing the mobile terminal. For example, the tactile output mode can be entered in various cases such as when a video call is being executed, when a telephone receiving window is displayed, when an image such as a gallery or the Internet is output, and the like.
When the user enters the tactile output mode, the controller 180 analyzes the image displayed on the touch screen 151 (S130). When the user touches the touch screen 151, the controller 180 outputs a touch corresponding to the image displayed in the corresponding area (S140).
If the user touch input is a valid input for selecting a menu or performing a specific function, the control unit 180 executes a function for the corresponding touch input (S150).

[ The control unit 180 outputs the tactile information set to the sender to the tactile output area F. [
The tactile information about the caller can be set by the user. For example, the first tactile information may be set for the caller A, and the second tactile information may be set for the caller B. Here, the tactile sensation can be recognized differently depending on the friction coefficient, and as the friction coefficient increases, the tactile sensation is felt. That is, the smaller the friction coefficient is, the more smooth the touch can be transmitted, and when the friction coefficient is high and the low region is repeated, the rough touch can be transmitted. The control unit 180 registers the tactile information for each phone number registered in the address book according to the setting of the user, and then outputs the tactile information set to the caller when the call is received.
