The operation signal can be generated by adding.

Structurally, the first body 101a and the second body 101b may be fused to each other to form a one body that is indistinguishable in appearance. In this case, the second body 101b may be rigidly coupled to the first body 101a while rigid enough to deform the second body 101b with respect to the pressure applied to the second body 101b. have.

Alternatively, the first body 101a and the second body 101b may be formed in a form separated from each other by a physical gap.

In order to arrange the first sensor group 201 and the second sensor group 202, the second body 101b includes a first protrusion 205 and a second protrusion 206 protruding in an inner direction of the first body 101a. And a first accommodation groove 203 and a second accommodation groove 204 for accommodating the first protrusion 205 and the second protrusion 206, respectively, are formed in the second body 101b. have. 3 shows that the protrusions 205 and 206 and the receiving grooves 203 and 204 are formed in a 'mushroom' shape. However, when the first protrusion 205, the second protrusion 206, the first accommodation groove 203, and the second accommodation groove 204 are applied to the second body 101 b by the force, the first protrusion 205 is provided. And the second protrusion 206 may be formed in any other shape capable of transmitting pressure to the inner walls of the first accommodation groove 203 and the second accommodation groove 204.

The first sensor group 201 and the second sensor group 202 include first to fourth sensors 210a, 210b, 210c, and 210d (211a, 211b, 211c and 211d). 3 and 4, the first sensors 210a and 211a are positioned in front of the first protrusion 205 and the second protrusion 206, respectively, and the second sensors 210b and 211b are the first protrusion 205. And third sensors 210c and 211c are respectively positioned on the rear surface of the second protrusion 206, and third sensors 210c and 211c are positioned on the top surfaces of the first protrusion 205 and the second protrusion 206, respectively. ) Are positioned on the lower surfaces of the first protrusion 205 and the second protrusion 206, respectively. Each sensor of the first sensor group 201 and the second sensor group 202 may be a known pressure sensing component or element.

The portable terminal 100 includes a three-dimensional touch controller to control a user interface to be output to the display unit 151 through the pressure sensed by the first sensor group 201 and the second sensor group 202. It is provided.

The three-dimensional touch controller may have a torsional force on the first body 101a of the second body 101b generated by the deviation of the pressure sensed by the first sensor group 201 and the second sensor group 202. Adjust the user interface to be displayed on the display unit 151 according to the size and direction of the). In the present disclosure, 'stereoscopic touch' has been named to describe touch by torsion, compression, or tension in various directions, and hereinafter, such terms will be used according to circumstances.

When a specific force is applied to the second body 101b, one of the first sensor group 201 and the second sensor group 202 among the sensors of the first sensor group 201 and the second sensor group 202 may be applied. One of them prevails over the other sensors. The three-dimensional touch controller according to the present invention is applied to the second body 101b by using the pressure of the sensor predominantly detected in the first sensor group 201 and the pressure of the sensor predominantly detected in the second sensor group 202. Determine the nature of the force.

5 is a flowchart illustrating a process of adjusting a user interface by a stereoscopic touch controller as an example related to the present invention. This process may be provided in some of a plurality of modes of the portable terminal.

First, when a force is applied to the second body 101b by the user, the first sensor group 201 and the second sensor group 202 sense pressure through the sensors (S10).

The three-dimensional touch controller specifies a sensor for which pressure prevailing compared to other sensors is detected for each of the first sensor group 201 and the second sensor group 202 (S20). For example, if the detected pressure of the second sensor 210b of the first sensor group 201 is greater than that of the first, third, and fourth sensors 210a, 210c, and 210d, the second sensor 210b is specified. By the same method, if the first sensor 211a of the second sensor group 202 is larger than the second, third, and fourth sensors 211b, 211c, and 211d, the detected pressure is greater than that of the first sensor 211a. Is specified.

Even if the dominant sensors of the first sensor group 201 and the second sensor group 202 are specified, if each pressure is less than the reference pressure, nothing is considered to be involuntary operation (or malfunction) of the user. That is, the three-dimensional touch controller determines whether the pressure sensed by the first sensor group 201 and the second sensor group 202 is greater than the reference pressure (S30).

Next, it is determined whether the combination of the specified sensors of the first sensor group 201 and the second sensor group 202 is within a predetermined set combination (S40).

In Table 1, as an example related to the present invention, the first sensor group 201, the second sensor group 202 and the corresponding force are described as a series (set of) cases that can be input (or manipulated) through the mobile terminal. It is shown by the property of (torsion).

First Sensor Group 2nd sensor group Nature of force (torsion) Case 1 First sensor First sensor Left torsion Case 2 Second sensor Second sensor Right twist Case 3 First sensor Second sensor Upper torsion Case 4 Second sensor First sensor Downward torsion Case 5 3rd sensor 3rd sensor Left compression Case 6 4th sensor 4th sensor Right seal

That is, if the specified combination of the sensors of the first sensor group 201 and the second sensor group 202 is not within a predetermined set of combinations, a visual or audible signal is generated that guides that nothing is executed or cannot be executed. Can be output (S60).

When the combination of the specified sensors of the first sensor group 201 and the second sensor group 202 is within a preset combination, the stereoscopic touch control unit outputs a user interface through the display unit 151 (S50). .

6A and 6B are front and side views illustrating an example in which the second body receives right twist. The illustrated hand is 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.

6A and 6B, the second body 101b is forced to rotate to the right about the y-y axis. 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. In this case, in the present disclosure, the right twist is defined, and as shown in Table 1 above, the first sensor 210a of the first sensor group 201 and the first sensor 211a of the second sensor group 202 predominate. If you are under pressure. In FIG. 6A, the first sensor 210a of the first sensor group 201 and the first sensor 211a of the second sensor group 202 are indicated by a dark small square. And, in the following description, each sensor specified in each case will likewise be indicated by a dark small square.

6C to 6D are diagrams illustrating operating states of user interfaces displayed through the display unit 151 in the case of FIG. 6A.

6C shows the pointer or cursor moving leftward. That is, in a specific mode in which the pointer or the cursor is set to move, the pointer or the cursor can be moved only by applying force as shown in FIG. 6A.

6D shows that the size is reduced by moving the pointer placed on the volume or time axis to the left.

This output effect is consistent with the feeling that the cursor or pointer is pushed to the left in the direction of the force applied to the second body 101b in 6C and 6D.

In addition, the right twist may be set to mean that the display unit 151 returns to the previous screen.

7A and 7B are front and side views illustrating an example in which the second body is left twisted.

In FIGS. 7A and 67, the second body 101b is forced to rotate to the left about the y-y axis.

9C shows that the pointer or cursor moves in the right direction. That is, in a specific mode in which the pointer or the cursor is set to move, the pointer or the cursor may be moved only by applying force as shown in FIG. 7A.

7D shows that the size is reduced by moving the pointer placed on the volume or time axis to the left.

This output effect is consistent with the feeling of 7C and FIG. 7D as if the cursor or pointer is dragging right when viewed in the direction of the force applied to the second body 101b.

In addition, the left twist may be set to mean that the display unit 151 moves to the next screen.

8A and 8B are front and side views illustrating an exemplary case where the second body is subjected to upward twisting, respectively.

The second body 101b is subjected to a force that is twisted upward about the x-x axis. In this case, in the present disclosure, it is defined as 'upward torsion', and as shown in Table 1 above, the second sensor 210b of the first sensor group 201 and the first sensor 211a of the second sensor group 202 predominate. If you are under pressure.

8C to 8D are diagrams illustrating operating states of user interfaces displayed through the display unit 151 in the case of FIG. 8A.

8C shows scrolling up a pointer on any list. When viewed in the direction of the force applied to the second body (101b) corresponds to the feeling of dragging the pointer in the upward direction. In this case, the three-dimensional touch controller may change the size of the scroll according to the amount of torsional force. For example, it is possible to have the scroll amount move by one unit when one torsional force is applied, the scrolling continues when the torsional force is applied for a certain time, and the scroll amount increases when the torsional force is further increased. .

8D shows increasing the level of any state quantity. That is, it can be seen that the amount that can be adjusted, for example, volume, brightness, etc., can be increased only by applying force as shown in FIG. 8A.

8E shows moving the pointer or cursor upwards. This output effect is also consistent with the feeling that the cursor or pointer is dragging upward when viewed in the direction of the force applied to the second body 101b.

9A and 9B are front and side views illustrating an example in which the second body is subjected to the downward twist.

The second body 101b is subjected to a force that is twisted upward about the x-x axis. In this case, in the present disclosure, it is defined as a 'downward twist', and as shown in Table 1 above, the first sensor 210a of the first sensor group 201 and the second sensor 211b of the second sensor group 202 predominate. If you are under pressure.

9C to 9E are diagrams illustrating operating states of the user interfaces displayed through the display unit 151 in the case of FIG. 9A. The output effects shown in FIGS. 9C through 9E are opposite to those described with reference to FIGS. 8C through 8E, and thus detailed description thereof will be omitted.

10 is a front view exemplarily illustrating a case in which the second body is compressed to the left.

In other words, the second body 101b is pushed to the left. In this case, in the present disclosure, it is defined as 'left compression', and as shown in Table 1 above, the third sensor 210c of the first sensor group 201 and the third sensor 211c of the second sensor group 202 predominate. If you are under pressure.

10 shows that the screen output through the display unit 151 is reduced. When viewed in the direction of the force applied to the second body (101b) also corresponds to the feeling that the display unit 151 is intended to shrink.

11 is a front view exemplarily illustrating a case in which the second body is pulled to the right.

In other words, the second body 101b is being forced to be pulled to the right. In this case, in the present disclosure, the right tension is defined, and as shown in Table 1, the fourth sensor 210d of the first sensor group 201 and the fourth sensor 211d of the second sensor group 202 predominate. If you are under pressure.

11 shows that the screen output through the display unit 151 is enlarged. When viewed in the direction of the force applied to the second body (101b) also corresponds to the feeling of expanding the display unit 151.

12 is an operation state diagram showing a user interface output by a stereoscopic touch as an example related to the present invention.

12 illustrates a cube puzzle through a mobile terminal. That is, the cube output through the display unit 151 simulates the actual one. The user may apply a force to the second body 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 stereoscopic 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 displayed on the front side, and the list shown on the front side is rotated and moved to another side by the user's three-dimensional touch method, while the other list is placed in front.

If a force to rotate the second body upward in the state of FIG. 13 (a) is applied, the three-dimensional menu outputs an image that appears to be rotated (FIG. 13 (b)), and the next list is displayed in front (FIG. 13 (c)). )).

14 shows a process of selecting a submenu of an item on which a pointer is located among a list displayed on the front side.

When a force is applied in the direction of rotating the second body 101b to the left in the state of FIG. 14 (a), the three-dimensional menu is rotated to the left (FIG. 14B) and the submenu list is output to the front (FIG. 14). (c)). Then, a desired item is selected by applying a force in a direction of rotating the second body 101b upward or downward.

However, the arrangement of the upper menu and the arrangement of the sub menu may be set differently from the directions disclosed in FIGS. 13 and 14.

15 shows another user interface showing a process of selecting a submenu of an item on which a pointer is located among a list displayed on the front side.

In a state as shown in FIG. 15A, in which items are listed up and down, a desired item may be selected by applying an upper twist or a lower twist to the second body 101b.

Then, when the right side seal is applied to the second body 101b to view the subitems of the selected item, the upper list is reduced to the left, and the sublist of the selected item is drawn out as shown (Fig. 15 (b)). This effect is natural in that it is consistent with the operation of taking out the paper (sheet) that is actually hidden or shrunk.

The desired sub-item may be selected by applying an upward or downward twist to the list of the selected sub-items (FIG. 15 (c)).

If the second body 101b is compressed to the left while the list of sub items is expanded, the list of sub items disappears as if entering the list of main items, and the list of main items is expanded and output again (FIG. 15 ( d)).

16 is a perspective view of a portable terminal showing a push button mounted on a second body as an example related to the present invention.

By arranging the pushbutton 230 in the second body 101b, a simple and direct input can be facilitated. Pushbutton 230 may be more than shown.

In the case of three-dimensional touch, the push button 230 may be set to indicate confirmation, cancellation, etc. for the selected item.

The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. Thus, proximity sensors have a considerably longer life than contact sensors and their utilization is also quite high. Examples of the proximity sensor include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

In the high frequency oscillation type proximity sensor, the oscillation amplitude of the rear oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface while oscillating the high frequency of the forward wave in the oscillation circuit, and converts this change into an electrical signal to sense the object. The presence or absence of a will be detected. Therefore, even if a non-metallic material comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

Even if the proximity sensor is not mounted, the touch screen may be configured to detect proximity of the pointer by a change in electric field according to proximity of the pointer when the touch screen is capacitive.

Therefore, when the pointer is not in contact but is in close proximity on the touch screen, the position of the pointer and the distance between the pointer and the touch screen may be detected.
