Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen. It is an image that makes you feel the same as reality space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means the parallax caused by the positions of the two separated eyes.

The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. 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.

If 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.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal 100 or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 measures the presence or absence of an object approaching a predetermined sensing surface It refers to a sensor that uses infrared rays to detect without mechanical contact.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like).

The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object 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 light change, thereby acquiring position information of the object to be sensed.

3C is a conceptual diagram for explaining the mobile terminal 100 controlled by the controller.

Referring to FIG. 3C, the input device 400 may correspond to a stylus pen which is detachable from the main body of the mobile terminal 100 and is capable of applying a control command to the mobile terminal. The stylus pen is an apparatus for converting graphic data into data that can be input to a computer storage device. Generally, one end of the stylus pen is formed into a pen shape that touches the display unit 151 and inputs a signal.

The input device 400 may be inserted into the inner space of the mobile terminal body. However, the external appearance of the input device 400 may be formed in a shape other than a pen shape.

3C, a current value flowing through the display unit 151 is changed by a stylus pen that is in contact with the display unit 151, and a specific image can be generated on the display unit 151. FIG.

According to the present invention, different control signals are applied to the mobile terminal using the input device (400). Hereinafter, a specific structure of the input device 400 and a method of controlling the mobile terminal using the input device 400 will be described.

4 is a cross-sectional view of an input device according to the present invention. 4, the input device 400 includes a body part 400 extending in one direction, an input part 420, a battery 450, vibration parts 440 and 441 (see FIGS. 6A and 6B) A motion sensor unit 470 and a control unit 430, a wireless communication unit (not shown), and a pressing unit 460.

The signal generated by the input unit 420 is transmitted to the mobile terminal through the wireless communication module (not shown).

FIGS. 5A and 5B are partial cross-sectional views illustrating the structure of the input unit 420. FIG.

4 and 5A, the input unit 420 includes a contact unit 421, a support bar 422, an elastic unit 423, and a sensing unit 424. The contact portion 421 is exposed to the outside of the body 410. The contact portion 421 is formed of a conductive material. Therefore, when the display unit 151 contacts the display unit 151, the current value of the display unit 151 changes, and a signal is input to the area where the contact unit 421 contacts the display unit 151.

The contact portion 421 is preferably made of a rubber material having elasticity for a more natural feel to the user. Accordingly, even when the display unit 151 is in contact with the display unit 151, damage to the display unit 151 can be prevented.

Here, the pressure applied to the contact portion 421 is formed by the pressure applied to the body portion 410 by the user in a state where the contact portion 421 is in contact with the display portion 151 or a specific object .

The contact portion 421 is formed at one end of a support rod 422 mounted inside the body portion 410. The support bar 422 is formed in one direction and is formed to be movable along the one direction by the pressure applied to the contact portion 421.

The sensing part 424 is formed at the other end of the support rod 422. The sensing part 424 according to the present embodiment is implemented as a pressure sensing sensor. The pressure sensor is formed with a switch, and the other end of the support rod 422 is supported.

That is, the support bar 422 moves along one direction by the pressure applied to the contact portion 421. Accordingly, since the switch of the pressure sensor is pressed, the pressure sensor can sense the pressure applied to the contact portion 421. Also, the sensing unit 424 may sense the degree of physical pressure applied to the contact unit 421. That is, the pressure sensor is formed such that the resistance value is changed by the pressure.

The elastic portion 422 may be formed in a spring shape. The elastic portion 423 is formed between the support bars 422 and the support frames including the holes so that the support bar 422 can pass therethrough. The elastic portion 423 is formed to move the support rod 422 moved by the pressure back into place. Accordingly, the contact portion 421 moved into the body 410 by the user moves to be exposed to the outside by the elastic portion 423 when the pressure is released.

In addition, the elastic portion 423 can apply pressure to the contact portion 421 in a stepwise manner.

A battery 450 is mounted inside the body 410 to provide power to the sensing unit 424 and the control unit 430.

The control unit 430 may further include a circuit board and a storage unit. The circuit board is electrically connected to each component and transmits an input signal, and the storage unit stores information transmitted from the mobile terminal.

The control unit 430 controls the control unit 430 to generate a control signal for controlling the mobile terminal, based on the pressure value sensed by the sensing unit 424.

For example, the control unit 430 may convert the analog signal value sensed by the sensing unit 424 into a digital signal for transmission to the mobile terminal. That is, the control unit 430 may include an analog-to-digital converter (ADC).

The control unit 430 controls the radio communication unit to transmit the control signal to the mobile terminal. For example, the wireless communication unit can be implemented by Bluetooth. That is, when the mobile terminal body and the input device 400 are disposed closely to each other, the mobile terminal can be transmitted using the input device 400.

That is, since the input device according to the present invention senses the pressure change by the outside, different control commands can be applied according to the pressure. Further, even when the input device 400 is disposed apart from the mobile terminal by the wireless communication module, the control command can be more accurately applied.

Meanwhile, the sensing unit of the input device 400 according to another embodiment of the present invention includes an infrared sensor instead of the pressure sensor. The configuration of the sensing unit according to another embodiment will be discussed with reference to FIG.

The sensing unit 420 according to the present embodiment includes a contact unit 427, a support rod 422, and an infrared sensor 425. One region of the contact portion 427 is exposed to the outside, and can be contacted with the display portion 151 and other objects. The contact portion 427 is moved to the inside of the body portion 410 by the physical pressure applied to the contact portion 427.

The cross section of the contact portion 427 is formed so as to be wider as it goes inside the body portion 410. The contact portion 427 is formed so as to be surrounded by the inner periphery of one end of the body portion 410. The inner circumference of the body part 410 and the inner circumference of the contact part 427 may have a predetermined gap.

The gap between the body 410 and the contact portion 427 is enlarged when the contact portion 427 moves to the inside of the body 410 by the pressure applied to the contact portion 427. [

The infrared sensor 425 includes a discharge unit that emits infrared rays and a detection unit that detects infrared rays that have passed through the contact unit 427. The discharge part and the detection part are mounted inside the body part 410 and are formed with the contact part 427 interposed therebetween.

Accordingly, when the contact portion 427 moves to the inside of the body portion 410 due to the pressure, the width of the contact portion 427 through which the light passes is narrowed. Accordingly, the amount of the infrared ray lost while passing through the contact portion 427 is reduced and reduced.

Accordingly, the detection unit can detect a different amount of infrared ray in accordance with the movement of the contact unit 427, and thereby measure the pressure applied to the contact unit 427. [

The control unit 430 changes the analog signal according to the amount of infrared detected by the infrared sensor to a digital signal and controls the wireless communication module to transmit the analog signal to the mobile terminal.

Since the movement of the contact portion is detected by the infrared sensor, a minute pressure change can be measured and a more accurate control command can be transmitted.

6A and 6B are cross-sectional views for explaining a vibrating part mounted on a body part according to each embodiment.

Referring to FIGS. 4 and 6A, the first vibration unit 440 includes a first vibration unit 440 and a second vibration unit 440. The first vibration unit 440 is disposed on the inner surface of the body 410 to improve the effect of the control unit check vibration transmitted to the user. It is preferable to be formed so as to be in contact with each other. The first vibrating unit may be formed of a coin motor LRA, a cylinder motor ERM, or the like.

The first vibration unit 440 is controlled to vibrate according to a digital signal according to the change of the input unit 420. For example, the first vibration unit 440 may be controlled to vibrate at different intensities by different digital signals at different pressures.

In addition, the first vibration unit 440 may vibrate in different vibration modes by the different digital signals. For example, the first vibration unit 440 may operate at various vibration periods and vibration widths.

The first vibration unit 440 may be formed on one side of the body 410 where the user's hand contacts.

The user can recognize the pressure applied to the body part 410 by the first vibrating part 440 and anticipate the control command applied to the mobile terminal 100 by the pressure.

6B is a view for explaining a second vibration unit 441 according to another embodiment. 6B, the second vibration unit 441 may be formed along the outer circumferential surface of the body 410, and the lid unit 422 may be formed to enclose the second vibration unit 441.

The second vibration unit 441 may be formed of a piezo film. The physical shape of the piezoelectric film is changed according to the current value. The second vibration unit 441 changes the physical shape by the digital signal, and accordingly, the user senses vibration by hand.

In addition, the second vibration unit 441 may vibrate in different vibration modes by the different digital signals. For example, the second vibration portion 441 can operate at various vibration periods and vibration widths.

It is possible to prevent the second vibrating unit 441 from being exposed and separated from the body 410 according to the cover unit 422, thereby improving the beauty of the appearance.

Since the second vibrating unit 441 is formed in the form of a thin film, the internal space of the input device 400 can be secured and the size of the body 410 can be minimized.

The motion sensor unit 470 is formed inside the body 410. The movement of the body 410 is detected by the motion sensor 470 and a control signal for controlling the mobile terminal can be generated based on the motion.

The motion sensor unit 470 may include an acceleration sensor and a gyro sensor.

The acceleration sensor senses the movement of the body 410 in the air as a sensor for measuring the acceleration or impact of the object. That is, the movement of the body part 410 can be sensed from three axes perpendicular to each other.

The gyro sensor is a sensor for sensing rotational inertia. The gyro sensor may sense the rotation of the body 410 with respect to the three axes.

The motion sensor unit 470 senses motion of the body 410 and transmits the motion signal to the control unit 430. [ The motion signal corresponds to an analog signal, and the control unit 430 controls the wireless communication unit to convert the motion signal into a control signal of the mobile terminal, which is a digital signal, and transmit the control signal to the mobile terminal.

The pressing part 460 is formed on the outer surface of the body part 410 and is formed to be pressed by the pressure of the user. A control signal different from the control signal can be generated by the pressure applied to the latch room 460.

As described above, a control signal can be generated according to the pressure applied to the input unit 420, the pressure applied to the pressing unit 460, and the movement of the body 410. The control signal controls the mobile terminal by the wireless communication module.

Hereinafter, the control method of the mobile terminal will be described based on each control signal.

FIGS. 7A and 7B are conceptual diagrams for explaining a control method of a mobile terminal when an input unit is contacted to the display unit 151. FIG.

4 and 7A, the controller controls the wireless communication unit 110 to receive a control signal of the input device 400, which is in contact with the display unit 151 and is applied with predetermined pressure. The control unit 180 controls the display unit 151 to display an image based on the control signal.

For example, the image may be formed along the path of the touch input applied to the display unit 151 by the input device 400.

The control unit 180 controls the display unit 151 to display images of different sizes (different widths) based on different control signals generated according to different pressures applied to the input unit 420.

For example, when a larger pressure is applied to the body part by the user and a pressure value applied to the input part 420 increases, the size of the image applied to the display part 151 may be larger .

Accordingly, when the user desires to form an image on the display unit 151, the user can change the shape of the image by adjusting the pressure applied to the body part. Therefore, it is possible to control the display unit 151 to output more various images without setting the size of the image output to the display unit 151 separately.

Referring to FIGS. 4 and 7B, the display unit 151 outputs screen information 510. The control unit 180 controls the wireless communication unit 110 to receive a control signal of the input device 400 which is in contact with the display unit 151 and to which a predetermined pressure is applied. The control unit 180 controls the display unit 151 to enlarge or reduce the screen information based on the control signal.

For example, when an increased pressure applied to the input device 400 is applied in a state of being in contact with a specific point on the display unit 151, a control signal based on the pressure value is generated, Controls the wireless communication unit 110 to receive the control signal.

The control unit 180 controls the display unit 151 to enlarge and output the screen information based on the specific point on the basis of the control signal.

The controller 180 controls the display unit 151 to reduce the screen information by another control signal based on the pressure value when a pressure lower than the pressure inputted to the input device 400 is applied. .

That is, the controller 180 may change the aspect ratio of the screen information based on different control signals according to the pressure values.

Meanwhile, the controller 180 adjusts the screen ratio of the screen information according to a control signal based on a pressure greater than the reference pressure on the basis of a predetermined reference pressure, It is possible to control the display unit 151 to output images of different sizes.

However, the present invention is not limited to controlling the enlargement or reduction of the screen information, and it is possible to control switching of the screen information, erection of the display unit 151, and the like.

According to the present embodiment, a user can more easily control the screen information without applying a separate control command.

8A and 8B are conceptual diagrams for explaining a control method of a mobile terminal when an input unit is in contact with another object.

Here, the other object means an object other than the display unit 151. For example, the display unit 151 may be in contact with a table adjacent to the display unit 151. The region to which the input device 400 contacts, specifically, the contact portion 421 is contacted preferably includes a substantially flat surface.

The object and the display unit 151 may be spaced apart from each other within a predetermined distance. The predetermined distance corresponds to a distance at which the input device 400 and the mobile terminal can transmit or receive control signals with each other. And may be variously set by the wireless communication unit 110 and the wireless device included in the wireless communication module.

When the object and the contact portion 421 are in contact with each other, pressure is applied to the contact portion 421 in the same manner as the contact with the display portion 151. Accordingly, a control signal corresponding to the pressure value is generated, and the mobile terminal receives the control signal and controls the mobile terminal.

It is apparent that the touch input applied to the display unit 151 by the contact unit 421 is limited.

4 and 8A, when the input device 400 is contacted to the object and a pressure is applied to the contact portion 421, the controller 180 controls the display (151). The pointer 502 may be formed in one area of the display unit 151, but is preferably displayed at the center of the display unit 151.

According to the output of the pointer 502, the user can check the state controlled by the input device 400.

Referring to FIG. 8A, the control unit 180 outputs a first image 502 'corresponding to the movement of the input device 400, based on a control signal of the input device 400 moved on the object And controls the display unit 151.

Also, based on another control signal received from the input device when a larger pressure is applied to the input device 400, the control unit 180 controls the second image 502 '' having a larger size (width) And controls the display unit 151 to output the output signal.
