Hereinafter, a temporary operation method and a terminal of an operation target according to a touch pressure and a touch area according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a view showing a terminal according to an embodiment of the present invention, FIGS. 2A and 2B are diagrams for explaining a change amount of capacitance due to an area, and FIGS. 3A and 3B show a change amount of capacitance due to pressure 4A and 4B illustrate a single touch and multiple touches, respectively.

1 to 4, the terminal 1 according to an embodiment of the present invention includes a touch panel 10, a control unit 20, and a processor 30.

When the terminal 1 touches at least one object 50 on the surface of the touch panel 10, the terminal 1 analyzes the touch position of the object 50, the size of the touch pressure of the object 50, and/or the touch area Operation control corresponding to the touch may be performed. Here, the object 50 may correspond to a part of the human body, or may correspond to a stylus pen.

Therefore, the user can operate the terminal 1 by touching (touching) the surface of the touch panel 10 with the object 50.

The touch panel 10 may be a touch screen. Further, the touch panel 10 may be a transparent panel including a touch-sensitive surface attached to the front surface of a display panel (not shown).

The touch panel 10 may include two electrodes, and when the touch of the touch panel 10 occurs, the two electrodes may change mutual capacitance and/or self capacitance. Also, the touch panel 10 may further include a separate electrode capable of detecting touch pressure.

The processor 30 may detect the size and/or touch area of the touch pressure input to the touch panel 10 and the touch position (or coordinate) of the object 50 touched on the touch panel 10.

The processor 30 may detect the touch position by the touch of the object 50, the size of the touch pressure, and/or the touch area. In addition, the processor 30 may store the digitized information in the storage means 40 of the terminal 1 by digitizing the detected touch position, the size of the touch pressure, and/or the touch area.

Specifically, the processor 30 may calculate a touch area for the touch panel 10 according to the detected amount of change in capacitance. More specifically, as the touch area of the object 50 touched on the touch panel 10 increases, the sum of the capacitance change amount may also increase. For example, as shown in FIG. 2A, the sum of the amount of change in capacitance when the area of the object 50 touched on the touch panel 10 is a is 90 (=50+10+10+10+10). to be. At this time, as shown in FIG. 2B, when the area of the object 50 that is touched on the touch panel 10 is increased from a to b (b>a), the sum of the amount of change in capacitance is 310 (=50+45+). 45+45+45+20+20+20+20). That is, the processor 30 may calculate the touch area using the amount of change in capacitance measured by the control unit 20.

In addition, the processor 30 may calculate the size of the touch pressure on the touch panel 10 according to the detected change in capacitance. More specifically, as the size of the touch pressure of the object 50 touched on the touch panel 10 increases, the sum of the capacitance change amount may also increase. For example, as shown in FIG. 3A, when the object 50 is touched to the touch panel 10 without pressure (simple contact), the sum of the amount of change in capacitance is 90 (=50+10+10+10+) 10). At this time, as shown in FIG. 3B, when the object 50 is touched to the touch panel 10 by applying a predetermined pressure, the sum of the amount of change in the capacitance is 570 (=90+70+70+70+70+50+) 50+50+50). Here, the area of the object 50 touched on the touch panel 10 in FIGS. 3A and 3B is the same as the area (a) of the object 50 touched on the touch panel 10 in FIG. 2A.

That is, the processor 30 may calculate the size of the touch pressure using the detected amount of change in capacitance.

The control unit 20 may perform the operation control of the operation target by using the touch position and the size of the touch pressure and/or the touch area information received from the processor 30.

The control unit 20 performs a first operation corresponding to the size and/or touch area of the touch pressure detected by the processor 30.

Specifically, the control unit 20 may perform an operation corresponding to the size and/or touch area of the touch pressure detected by the processor 30. For example, when the size and/or touch area of the touch pressure detected by the processor 30 is increased, the controller 20 may change the first state of the first operation to the second state of the first operation. Also, when the touch input to the touch panel 10 is released, the control unit 20 may return to the first state of the first operation from the second state of the first operation.

In addition, the control unit 20 may detect whether the touch input on the touch panel 10 is a single touch or multiple touches, whether it is a single touch, the size of the touch position and the touch pressure received from the processor 30, and / Or, using the touch area information, it is possible to perform motion control of the operation target.

Here, the single touch is an object 50 is touched once within a predetermined time on the touch panel 10 as shown in FIG. 4A, and the multi-touch is at least one object as shown in FIG. 4B ( 50) is touched on the touch panel 10 twice or more within a predetermined time. Specifically, the multi-touch may include a first touch and a second touch. At this time, the first touch may have a smaller touch pressure than the second touch, or a small touch area, and may have both a small touch pressure and a touch area. In addition, a time for the object 50 to release contact with the touch panel 20 may be included between the first touch and the second touch.

When a single touch is detected, the controller 20 performs a first operation corresponding to the magnitude and/or touch area of the touch pressure detected by the processor 30. On the other hand, when multiple touches are detected by the control unit 20, the second operation corresponding to the size and/or touch area of the touch pressure detected by the processor 30 may be performed.

In addition, the control unit 20 may perform an operation corresponding to the size and/or touch area of the touch pressure detected by the processor 30. For example, when the touch input on the touch panel 10 is a single touch, when the size and/or touch area of the touch pressure detected by the processor 30 is increased, the control unit 20 first state of the first operation Can be changed to the second state of the first operation. Also, when the touch input to the touch panel 10 is released, the control unit 20 may return to the first state of the first operation from the second state of the first operation.

When the touch input on the touch panel 10 is a multi-touch, when the size and/or touch area of the touch pressure detected by the processor 30 becomes large, the control unit 20 sets the first state of the second operation to the second It can be changed to the second state of operation. Also, when the touch input to the touch panel 10 is released, the control unit 20 may return to the first state of the second operation from the second state of the second operation.

Specifically, it will be described in the following embodiments.

5 is a diagram illustrating application examples of motion control of an operation target.

Referring to FIG. 5, the motion control of an operation target according to an embodiment of the present invention is up/down of a volume, zooming in/out of a screen, fast/slow playback speed, adjusting an object moving direction, scrolling ( scroll) may include adjusting the moving direction, adjusting the contrast and adjusting the saturation. Here, the second operation may be an operation opposite to the first operation.

Specifically, if the first operation is up of the volume, the second operation may be down of the volume, and if the first operation is enlargement of the screen, the second operation may be reduction of the screen, and the first operation may speed up the playback speed. The second operation may be a slowing of the playback speed. If the first operation is a movement of the object downward, the second operation may be a movement of the object upward, and the second movement may be a movement of the object downward. It may be scrolling upward, and if the first operation is bright, the second operation may be dark, and if the first operation is dark, the second operation may be light.

Here, when the touch panel 10 included in the terminal 1 according to an embodiment of the present invention is attached to a display panel (not shown), the items displayed on the display panel can be confirmed through a screen. The screen may be a touch screen, and a touch on the touch panel 10 may be performed by a user touching the touch screen. Alternatively, the touch panel 10 in which the touch by the screen and the object is performed may be implemented separately.

When the application example is described in more detail, the enlargement/reduction of the screen indicates a case in which the size of all or part of the screen displayed on the screen is enlarged or reduced. For example, when a character is displayed on the screen, a part of the character displayed on the screen may be temporarily enlarged or reduced to a desired magnification. Alternatively, the zoom size of a specific object displayed on the screen may be adjusted. For example, only an image such as a picture displayed on the screen may be temporarily enlarged/reduced, and a map displayed on the screen may be temporarily enlarged/reduced.

Up/down of the volume represents a case where the device having the terminal 1 according to an embodiment of the present invention temporarily increases or decreases the sound volume of a corresponding file when playing a video or audio file.

When the playback speed is fast/slow, when the device equipped with the terminal 1 according to the embodiment of the present invention plays a video, it indicates that the playback speed is temporarily fast or slow.

Adjusting the movement direction of the object may temporarily adjust the movement direction for selecting a specific object among a plurality of objects, or vertically, horizontally, or left and right movement of the specific object displayed on the screen. For example, a plurality of pictures displayed on the screen may be'flip forward' or'flip backward'.

The scroll movement direction may be temporarily moved up or down or left and right, for example, when the scroll bar is explicitly or implicitly displayed on the screen.

Contrast/saturation adjustment may indicate temporarily adjusting a screen brightness or saturation size value.

6 illustrates an operation according to an embodiment of the present invention.

Referring to FIG. 6, an operation according to an embodiment of the present invention includes a process of touching an object 50 on the touch panel 10, applying pressure, and releasing the pressure again.

7A and 7B show an embodiment of the first operation according to the operation illustrated in FIG. 6.

Referring to FIGS. 7A and 7B, the first operation may include an operation of expanding a region to be enlarged by a user from a first state to a second state, and then returning from the second state to the first state. At this time, the enlarged area or enlarged magnification may be changed by the size of the touch pressure and/or the touch area. Here, the first operation may be an operation of reducing the area to be reduced by the user from the first state to the second state, and then returning from the second state to the first state, but the second state is expanded below. For example, explain.

Specifically, as shown in FIG. 7A, a screen in a first state is displayed on the touch screen before a touch is input to the touch panel 10. Thereafter, when a touch is input to the touch panel 10, a magnifier is displayed at a touch position, and when the input touch is a single touch, the size of the touch pressure and/or the character included in the magnifier area as the touch area increases. Although the magnification is kept constant, it can be seen that the magnifier area becomes the second state that is enlarged than the first state. Thereafter, as the size and/or touch area of the touch pressure decreases, the magnifier area in the second state gradually decreases, and when the touch input to the touch panel 10 is completely released (release), the first touch screen is displayed again. The status screen is displayed.

In addition, as illustrated in FIG. 7B, as the size and/or touch area of the touch pressure increases, the magnifier area is kept constant, and it can be seen that the character included in the magnifier area becomes a second state that is enlarged. Thereafter, as the size and/or touch area of the touch pressure decreases, the characters in the second state are gradually reduced, and when the touch input to the touch panel 10 is completely released (release), the first state is again displayed on the touch screen. The screen of is displayed.

Here, the magnification area of the magnifier and the magnification of the characters included in the magnifier area may be simultaneously adjusted according to the size and/or touch area of the touch pressure.

If the size of the touch pressure and/or the touch area is rapidly increased, the magnification speed of the characters included in the corresponding magnification area and/or the magnification area may increase, and the size and/or touch area of the touch pressure may quickly decrease. If it is, the reduction speed of the corresponding character can be increased.

In addition, by adjusting the size and/or touch area of the touch pressure input to the touch panel 10 in the second state, the characters included in the magnifier area can be enlarged to a desired magnification.

In addition, by sliding the object 50 touched on the touch panel 10 in the second state, the desired area can be enlarged by moving the magnifier area.

Here, in order not to cover the magnifier with a touch object such as a finger, the magnifier area may be displayed at a position offset from the touch position by a predetermined distance.

Specifically, the offset between the center of the magnifier area and the touch position may be changed according to the size and/or touch area of the touch pressure. As shown in FIG. 7A, the magnification of the characters included in the magnifier area is kept constant, but when the magnifier area is enlarged, the touch position and the center of the magnifier area are determined according to the size and/or touch area of the touch pressure. The offset can be changed. More specifically, when the size and/or touch area of the touch pressure is increased, the offset between the touch position and the center of the magnifier area is increased, and when the size and/or touch area of the touch pressure is small, the center of the touch position and the magnifier area is increased. By reducing the offset of, it is possible to always display the border of the magnifier area at approximately the touch position.

In addition, as shown in FIG. 7B, the magnifier area is kept constant, but when the characters included in the magnifier area are enlarged, the touch position and the center of the magnifier area are independent of the size and/or touch area of the touch pressure. The offset can be set constant. More specifically, the offset between the touch position and the center of the magnifier area may be set to have a radius value of the magnifier area, so that the border of the magnifier area is always displayed approximately at the touch position.

At this time, regardless of the direction in which the touch panel 10 is placed, the position where the magnifier area is offset may be positioned in a predetermined direction of the touch position based on the screen direction displayed on the touch panel 10. Specifically, using a sensor such as a gyroscope or a gravity sensor, regardless of the direction in which the touch panel 10 is placed, such as in the horizontal or vertical direction, the magnifier area is based on the screen direction displayed on the touch panel 10. Since the display can be offset so as to be offset in the direction set by the user, for example, above the touch position, even if the touch panel 10 is rotated from the horizontal direction to the vertical direction, or from the vertical direction to the horizontal direction, the magnifier area may become It is not obscured by the touch object, and can be offset in a constant direction at all times.

8 illustrates an embodiment of the second operation according to the operation illustrated in FIG. 6.

Here, the second operation is an operation opposite to the first operation, and is an operation to reduce the pressure according to the size and/or touch area of the touch pressure.

Referring to FIG. 8, the second operation may include an operation of reducing an area to be reduced by the user from a first state to a second state, and then returning from the second state to the first state. At this time, the reduced area or reduced magnification may be changed by the size of the touch pressure and/or the touch area.

Specifically, as illustrated in FIG. 8, a screen in a first state is displayed on the touch screen before a touch is input to the touch panel 10. Thereafter, when a touch is input to the touch panel 10, a magnifier is displayed at a touch position, and when the input touch is multiple touches, the magnifier area is kept constant as the size and/or touch area of the touch pressure increases. , It can be seen that the characters included in the magnifier area become the reduced second state than the first state. Thereafter, as the size and/or the touch area of the touch pressure decreases, the characters in the second state are gradually enlarged, and when the touch input to the touch panel 10 is completely released (release), the first state is again displayed on the touch screen. The screen of is displayed.

In this way, a user may temporarily enlarge or reduce a portion of the displayed screen desired to enlarge or reduce with a simple touch input to display the enlarged or reduced region, and then confirm the enlarged or reduced region, and then release the input touch. , It is possible to display the original screen again.

FIG. 9 shows another embodiment of the first operation according to the operation illustrated in FIG. 6, and FIG. 10 shows another embodiment of the second operation according to the operation illustrated in FIG. 6. Here, the descriptions of FIGS. 9 and 10 are similar to those of FIGS. 7A, 7B, and 8. Therefore, a description will be made focusing on different points.

9 and 10, the first operation may include an operation of expanding a map desired by a user from a first state to a second state, and then reducing the map from the second state to the first state. The second operation may include an operation of reducing the map to be viewed by the user from the first state to the second state, and then expanding the map from the second state to the first state.

Specifically, as illustrated in FIG. 9, a map of the first state is displayed on the touch screen before a touch is input to the touch panel 10. Then, when a touch is input to the touch panel 10, when the input touch is a single touch, it is seen that the map becomes a second state enlarged from the first state as the size and/or touch area of the touch pressure increases. Can be. Thereafter, as the size and/or touch area of the touch pressure decreases, the map of the second state is gradually reduced, and when the touch input to the touch panel 10 is completely released (release), the first state is again displayed on the touch screen. The map of is displayed.

In addition, as illustrated in FIG. 10, a map of the first state is displayed on the touch screen before a touch is input to the touch panel 10. Thereafter, when a touch is input to the touch panel 10, when the input touch is a multi-touch, it is seen that the map becomes a reduced second state than the first state as the size and/or touch area of the touch pressure increases. Can be. Thereafter, as the size and/or touch area of the touch pressure decreases, the map of the second state is gradually enlarged, and when the touch input to the touch panel 10 is completely released (release), the first state is displayed on the touch screen again. The map of is displayed.

Here, the speed of changing the state of the map is as described in FIGS. 7A and 7B.

In addition, by adjusting the size and/or touch area of the touch pressure input to the touch panel 10 in the second state, the map can be enlarged or reduced to a desired magnification.

Here, the map may be enlarged or reduced around the touch location, or may be enlarged or reduced around the center of the screen regardless of the touch location,

In this way, the map that the user wants to zoom in or out with a simple touch input is temporarily enlarged or reduced to a desired magnification and displayed to check the enlarged or reduced map, and then releases the input touch, thereby returning the original state. You can have the map displayed.

Also, although not shown in FIGS. 7A, 7B, and 8 to 10, the operations described above are the same for other operation targets (volume, playback speed, object movement direction adjustment, scroll movement direction adjustment, and contrast/saturation adjustment). Can be applied.

Hereinafter, a temporary operation method of an operation target according to a touch pressure and a touch area according to an embodiment of the present invention will be described. Hereinafter, FIG. 1 will be referred to together.

11 is a flowchart for explaining a method of temporarily operating an operation target according to a touch pressure and a touch area according to an embodiment of the present invention.

1 and 11, first, an operation target is operated in a first state (S100 ). As an example, as shown in FIG. 7A, a screen in a first state is displayed on a touch screen before a touch is input to the touch panel 10.

The size and/or touch area of the touch pressure is detected (S200). When a touch is input to the touch panel 10, the processor 30 may calculate a touch area for the touch panel 10 according to the detected change in capacitance.

The operation target is operated in a second state according to the detected touch pressure size and/or touch area (S300). Here, the second state of the operation object may be changed by adjusting the size and/or touch area of the touch pressure input to the touch panel 10 in the second state. As an example, as illustrated in FIG. 7A, as the size and/or touch area of the touch pressure increases, the magnifier area becomes a second state enlarged from the first state.

It is checked whether the input touch is released (S400). If the input touch is not released, the process returns to step S200. As an example, as illustrated in FIG. 7A, the size of the touch pressure and/or the area of the magnifying glass in the second state is gradually reduced as the touch area decreases.

On the other hand, when the input touch is released, the operation target is operated in a first state (S500). As an example, as illustrated in FIG. 7A, when the touch input to the touch panel 10 is completely released, the first state screen is displayed again on the touch screen.

12 is a flowchart illustrating a method of temporarily operating an operation target according to a touch pressure and a touch area according to another embodiment of the present invention.

1 and 12, the operation target is operated in a first state (S1000). As an example, as shown in FIG. 7B, a screen in a first state is displayed on a touch screen before a touch is input to the touch panel 10.

It is determined whether the input touch is a single touch or multiple touches (S2000). When a touch is input to the touch panel 10, the control unit 20 detects whether the touch input on the touch panel 10 is a single touch or multiple touches.

When the input touch is a single touch, the size of the touch pressure and/or the touch area is detected (S3000). When a touch is input to the touch panel 10, the processor 30 may calculate a touch area for the touch panel 10 according to the detected change in capacitance.

The operation target is operated in the second state of the first operation according to the detected touch pressure size and/or touch area (S4000). Here, the second state of the operation object may be changed by adjusting the size and/or touch area of the touch pressure input to the touch panel 10 in the second state. As an example, as illustrated in FIG. 7B, as the size and/or touch area of the touch pressure increases, characters included in the magnifier area become a second state enlarged from the first state.

Check whether the input touch is released (S5000). If the input touch is not released, the process returns to step S3000. As an example, as shown in FIG. 7B, as the size and/or touch area of the touch pressure decreases, the characters in the second state are gradually reduced.

When the input touch is a multi-touch, the magnitude of the touch pressure and/or the touch area is detected (S3000'). When a touch is input to the touch panel 10, the processor 30 may calculate a touch area for the touch panel 10 according to the detected change in capacitance.

The operation target is operated in the second state of the second operation according to the detected touch pressure size and/or the touch area (S4000'). Here, the second state of the operation object may be changed by adjusting the size and/or touch area of the touch pressure input to the touch panel 10 in the second state. As an example, as illustrated in FIG. 8, as the size and/or touch area of the touch pressure increases, characters included in the magnifier area become a reduced second state than the first state.

Check whether the input touch is released (S5000'). If the input touch is not released, the process returns to step S3000'. As an example, as illustrated in FIG. 8, as the size of the touch pressure and/or the touch area decreases, characters in the second state are gradually enlarged.

On the other hand, when the input touch is released, the operation target is operated in the first state (S6000). For example, as illustrated in FIG. 7B or 8, when the touch input to the touch panel 10 is completely released (release), the screen of the first state is displayed again on the touch screen.

When a plurality of operation objects are simultaneously displayed on the touch screen, the control unit 20 may identify the operation object according to the touch position. This identification can be made before or after determining whether it is a single touch or multiple touches.
