Abstract

In one embodiment, a touch input device includes a touch screen and is configured to perform mutually different operations with respect to a first touch and a second touch on the touch screen. The first touch is maintained during a time period equal to or greater than a first time period, wherein the first touch is maintained at a pressure less than a first pressure within the first time period. The second touch has a time interval having a pressure greater than the first pressure within the first time period. The first pressure is controlled and set by an input to the touch screen.

First claim

What is claimed is:

1. A touch input device comprising:
a touch screen configured to receive a touch;
a controller configured to:
identify the touch as a long touch only when the touch (a) is maintained during a time period equal to or greater than a first time period, and (b) is maintained at a pressure less than a first pressure within the first time period;
identify the touch as a pressure touch only when the touch has a pressure greater than the first pressure within the first time period; and
perform mutually different operations with respect to the long touch and the pressure touch upon the identification of the long touch or the pressure touch.

2. The touch input device according to claim 1 , wherein the controller is further configured to:
identify the touch as a tap touch only when the touch (a) is maintained during a time period less than the first time period and (b) is maintained at a pressure less than the first pressure within the first time period; and
perform an operation different from the operations corresponding to the long touch and the pressure touch upon the identification of the tap touch.

3. The touch input device according to claim 1 , wherein the first pressure is separately controlled and set for each of a plurality of divided screens of the touch screen.

4. A method for distinguishing a touch type in a touch input device comprising a touch screen, the method comprising:
processing, with a programmable processor, a signal from a touch screen, the signal being generated in response to a touch on the touch screen;
distinguishing the touch type based on a pressure magnitude of the touch and a time period of the touch, distinguishing the touch type comprising:
distinguishing the touch as a pressure touch when the touch comprises a time interval during which the touch has a pressure greater than a first pressure within a first time period;
distinguishing the touch as a tap touch when the touch is released within the first time period without comprising a time interval during which the touch has a pressure greater than the first pressure within the first time period; and
distinguishing the touch as a long touch when the touch is not released within the first time period without comprising a time interval during which the touch has a pressure greater than the first pressure within the first time period; and

performing a different operation according to the distinguished touch type;
wherein the first pressure is controlled and set by an input to a setting bar when the setting bar is displayed on the touch screen.

5. The method according to claim 4 , further comprising a pre-process in which a user of the touch input device sets the first pressure.

6. The method according to claim 5 , wherein the pre-process in which a user of the touch input device sets the first pressure comprises a step in which the user sets separate first pressures for a plurality of divided areas of the touch screen.

7. A touch input device capable of distinguishing a touch type, the touch input device comprising:
a touch screen; and
a controller configured to distinguish the touch type based on a pressure magnitude of a touch on the touch screen and a time period of the touch, distinguishing the touch type comprising:
distinguishing the touch as a pressure touch when the touch comprises a time interval during which the touch has a pressure greater than a first pressure within a first time period;
distinguishing the touch as a tap touch when the touch is released within the first time period without comprising a time interval during which the touch has a pressure greater than the first pressure within the first time period; and
distinguishing the touch as a long touch when the touch is not released within the first time period without comprising a time interval during which the touch has a pressure greater than the first pressure within the first time period; and
perform a different operation according to the distinguished touch type;
wherein the first pressure is controlled and set by an input to a setting bar when the setting bar is displayed on the touch screen.

8. The touch input device according to claim 7 , wherein the controller further performs a pre-process in which a user of the touch input device sets the first pressure.

9. The touch input device according to claim 8 , wherein the pre-process in which a user of the touch input device sets the first pressure comprises a step in which the user sets separate first pressures for a plurality of divided areas of the touch screen.

10. The touch input device according to claim 1 , wherein the first pressure is controlled and set by an input to a setting bar when the setting bar is displayed on the touch screen.
