The terminal body 101 includes a case (casing, housing, cover, etc.) forming an external appearance. The case may be classified into a front case (see 102 of FIG. 3) and a rear case (see 103 of FIG. 3). Various electronic components are built in the space formed between the front case 102 and the rear case 103. At least one intermediate case may be additionally disposed between the front case 102 and the rear case 103. The cases may be formed by injecting a synthetic resin or made of a metal material such as stainless steel (STS) or titanium (Ti). It may be formed to have the same metal material.

In addition, the display unit 151 may include a touch sensing means to be input by a touch method. Therefore, if there is a touch on any part of the display unit 151, the content corresponding to the touched position is input. The content input by the touch method may be letters or numbers or menu items that can be indicated or designated in various modes. The touch sensing means is formed to be translucent so that the display unit 151 can be seen, and may include a structure for increasing the visibility of the touch screen in a bright place. Referring to FIG. 1, the display unit 151 occupies most of the front surface of the front case 102.

The side key 132 may be employed in any manner as long as the user is tactile in a tactile manner. The contents input by the side key 132 may be variously set. For example, the side keys 132 may be used to control commands of the image input unit 125, adjust the volume of sounds output from the sound output units 152 and 154, or switch the display unit 151 to the touch recognition mode. Can be input.

The sound input unit 122 may be implemented in the form of a microphone, for example, to receive a user's voice, other sounds, and the like.

The interface unit 170 may be disposed on the side of the terminal body 101. The interface unit 170 serves as a passage for allowing the mobile terminal 100 according to the present invention to exchange data with an external device. For example, the interface unit 170 is wired or wirelessly, a connection terminal for connecting with the earphone, a port for short-range communication (for example, an infrared port (IrDA Port), a Bluetooth port (Bluetooth Port), a wireless LAN port ( Wireless LAN Port) and the like, or at least one of power supply terminals for supplying power to the mobile terminal 100. The interface unit 170 may be implemented in the form of a socket for receiving an external card, such as a subscriber identification module (SIM) or a user identity module (UIM), a memory card for storing information.

FIG. 2 is a rear perspective view of the portable terminal shown in FIG. 1.

Referring to FIG. 2, a second image input unit 125 may be additionally mounted on the rear surface of the terminal body 101. The second image input unit 125 has a photographing direction substantially opposite to that of the first image input unit 121 disposed on the front of the terminal body 101, and is a camera having different pixels from the first image input unit 121. Can be.

For example, the first image input unit 121 has a low pixel so that the user's face is photographed and transmitted to the counterpart in case of a video call, and the second image input unit 125 immediately photographs a general subject. It is preferable to have a high pixel because it is not transmitted in many cases. The image input unit 125 may be installed in the terminal body 101 to be rotatable or pop-up.

The flash 127 and the mirror 126 are further disposed adjacent to the second image input unit 125. The flash 127 shines light toward the subject when the subject is photographed by the camera 126. The mirror 126 allows the user to see his / her own face or the like when photographing (self-photographing) the user by using the second image input unit 125.

The second sound output unit 154 may be further disposed on the rear surface of the terminal body 101. The second sound output unit 154 may implement a stereo function together with the first sound output unit 152 disposed on the front surface of the terminal body 101, and may be used to implement a speakerphone mode during a call.

The rear of the terminal body 101 is mounted with a power supply unit 190 for supplying power to the portable terminal (100). The power supply unit 190 may be built in the terminal body 101 or may be directly detachable from the outside of the terminal body 101.

1 and 2, the terminal body 101 is composed of a first portion 101a and a second portion 101b. The front of the first portion 101a is provided with a display unit 151, a first sound output unit 152, and the second portion 101b, the first sensor 201 and the second sensor for the torsion touch 202 is included.

Structurally, the first portion 101a and the second portion 101b may be fused with each other to be integrally formed without being distinguished in appearance. In this case, the second portion 101b may be rigidly formed so that the deformation degree of the second portion 101b is insignificant with respect to the pressure applied to the second portion 101b.

Alternatively, the first portion 101a and the second portion 101b may be formed to be separated from each other by a physical gap. In this case, the second portion 101b may be formed to be twisted by a small angle with respect to the first portion 101a, for example, an angle between 0 degrees and 10 degrees.

The second portion 101b may be gripped by the user's hand, and according to how the user grips the user's hand, the second part 101b may be a user interface to be output to the display unit 151 by the torsional touch controller according to the present invention. Can change.

As illustrated in FIG. 1, the first sensor 201 is formed on the first surface S1 of the first portion, and as shown in FIG. 2, the second sensor 202 is formed on the second surface S2 of the second portion. The first surface S1 and the second surface S2 are located opposite to each other with respect to the terminal body 101 so that a torsional force can be easily applied with one hand.

3 is a cross-sectional view taken along the line A-A of FIG. According to FIG. 3, the first sensor 201 and the second sensor 202 are formed in a thin and wide thin film form, and the position and size of the pressure applied can be measured. The first sensor 201 and the second sensor 202 may be used a sheet-like pressure sensing component.

The first sensor 201 detects the first pressure P1 applied to the first surface S1, and the second sensor 202 detects the second pressure P2 applied to the second surface.

The first sensor 201 and the second sensor 202 may be referred to as an example of a user input unit in that various input operations may be performed. For example, in a state in which the second sensor 202 does not operate, the first sensor 201 may be set to a specific mode to operate like a so-called 'touch pad'. That is, when there is a touch on a specific position on the second sensor 202, an input action corresponding to the position is performed. Similarly, a specific mode may be set to operate like the touch pad with the second sensor 202 in a state where the first sensor 201 does not operate.

4 is a conceptual diagram illustrating an operation concept of a sensor according to the present invention. That is, the quadrangular surface refers to the first sensor 201 and the second sensor 202, and the portion indicated by '▲' represents the first position L1 on the first surface S1 to which pressure is applied. The indicated parts mean each of the second positions L2 on the second surface S2 to which pressure is applied. Accordingly, the first position L1 may be set to be positioned horizontally by X and vertically by Y relative to the second position L2. It is assumed that the first pressure and the second pressure applied to the first position L1 and the second position L2 are both perpendicular to the first surface S1 and the second surface S2. Therefore, when the first pressure P1 and the second pressure P2 are applied as shown in FIG. 4, the difference between the position between the action line of the first pressure P1 and the action line of the second pressure P2 and the first pressure ( The direction of the twist received by the second portion 101b is determined by the magnitude of P1) and the second pressure P2.

The portable terminal 100 is provided with a torsion touch control unit for controlling a user interface to be output to the display unit 151 through the pressure sensed by the first sensor 201 and the second sensor 202. .

The torsion touch control unit is adapted to the difference between the first position where the first pressure P1 and the first pressure P1 act, and the second position L2 where the second pressure P2 and the second pressure P2 act. Adjust the user interface to be displayed on the display according to the direction and magnitude of the torsion generated by the torsion. When there are several places of the first pressure P1 applied to the first surface S1, the torsion touch control unit may be set to regard the position where the greatest pressure acts as the first position L1. Similarly, when there are several places of the second pressure P2 applied to the second surface S2, the torsion touch control unit may be set to regard the position where the largest pressure acts as the second position L2.

5 is a conceptual diagram that virtually displays an area that is not executed in order to prevent a malfunction. That is, as shown in Figure 5, whether the operation is determined according to whether the second position is within the set angle range with respect to the first position. If the first position is a value near 45 degrees, 135 degrees, 225 degrees, and 315 degrees with respect to the second position, the first position has no difference between the vertical distance and the horizontal distance with respect to the second position. Do not run anything. 5 shows that the first position is near 45 degrees (hatched area) with respect to the second position.

6 is a flowchart illustrating a process of adjusting a user interface by a torsion touch controller as an example related to the present invention.

First, it is detected whether there is a first pressure P1 and a second pressure P2 greater than the reference pressure on the first and second surfaces, respectively. If both the first pressure P1 and the second pressure P2 are not greater than the reference pressure, the portable terminal does nothing.

Next, when the first pressure P1 and the second pressure P2 are greater than the reference distance, the first position L1 and the second pressure P2 in which the first pressure P1 is detected are detected. It is determined whether the distance between the positions L2 is larger than the reference distance. If the distance between the first position and the second position is less than or equal to the reference distance, the portable terminal may be set to execute nothing or to execute a specific input. Here, the 'specific input' may be 'OK' or 'suspend'.

Even if the distance between the first position L1 and the second position L2 is greater than the reference distance, the portable terminal does nothing if the first position L1 is not within the reference angle range with respect to the second position L2. It may not be. If the first position (L1) is in the vicinity of 45 degrees, 135 degrees, 225 degrees, 315 degrees (hatched area) with respect to the second position (L2), as described in FIG. 5, the first position (L1) ) May not be regarded as dominant in any direction in terms of the horizontal or vertical direction with respect to the second position L2, so that execution may be blocked to prevent malfunction. In the above process, the order of the first decision process to the third decision process may be changed.

7A to 7E are conceptual views illustrating various torsional states sensed by the first sensor and the second sensor. The hands shown in FIGS. 7A-7E are somewhat smaller for the mobile terminal 100. However, it is a matter of course that the portable terminal 100 is smaller than that shown.

The mobile terminal 100 may be used while lying down at 90 degrees to provide a horizontal screen through the display unit 151. This usage state can be used frequently when performing functions related to multimedia. As such an example, it may be an internet, photographing or viewing a picture or video, document viewing or navigation function, or the like.

According to FIG. 7A, the first position L1 on which the first pressure P1 acts is located on the left side than the second position L2 on which the second pressure P2 acts. In this case, the terminal body 101 as a whole is forced to be bent toward the ground direction relative to the edge of the center. Substantially with respect to such a force, the terminal body 101 can only detect torques that involve or are not deformed.

According to FIG. 7B, the first position L1 on which the first pressure P1 acts is located on the right side than the second position L2 on which the second pressure P2 acts. In this case, the terminal body 101 is forced to be bent toward the center of the terminal body in the opposite direction of the ground as compared to the edge as a whole.

According to FIG. 7C, the first position L1 to which the first pressure P1 acts is located above the second position L2 to which the second pressure P2 acts. In this case, the upper end of the second portion 101b is inclined in the direction of the ground, and the lower end of the second portion 101b is inclined in the opposite direction of the ground, that is, the force is applied in the direction of applying the torsion. For such a force, the terminal body 101 can only sense torque with or without deformation.

According to FIG. 7D, in contrast to FIG. 7C, the first position L1 to which the first pressure P1 acts is located below the second position L2 to which the second pressure P2 acts. In this case, the lower end of the second portion 101b is inclined in the direction of the ground, and the upper end of the second portion 101b is subjected to a force in a direction inclined in the opposite direction of the ground.

FIG. 7E shows a case where the position is substantially the same above the first position L1 on which the first pressure P1 acts and the second position L2 on which the second pressure P2 acts. In this case, the second portion 101b does not apply a force in any direction with respect to the first portion 101a.

The case described in FIGS. 7A-7E may be referred to as 'torsional touch' in the present disclosure, hereinafter, such terms will be used according to circumstances.

9E shows that the size is reduced by moving the pointer placed on the volume or time axis to the left.

This output effect corresponds to the feeling of 9D and FIG. 9E as if the cursor or pointer is dragging right when viewed in the direction of the force applied to the second portion 101b.

10A and 10B are front and side views illustrating the directions of moments received by the second part when the force is applied, as in FIG. 7C. That is, the second portion 101b is under a force that is twisted upward about the x-x axis.

The user may apply a force on the second portion 101b to twist to rotate the selected column (FIG. 12B) or to rotate the selected row (FIG. 12C). This manipulation can also be matched with the direction of the force acting to rotate the cube.

13 and 14 are diagrams illustrating an operation state of a user interface output by a torsional touch as an example related to the present invention.

In FIG. 13, a three-dimensional menu formed in a three-dimensional form is output through a mobile terminal and a desired item is selected.

That is, the three-dimensional menu output through the display unit 151 is like a cube. The pointer may be located on the list output on the front side, and the list shown on the front side is rotated by the user's torsion touch method and moved to the other side, while the other list is placed in front.
