Abstract

A display system input device includes a touchpad including a touch surface; a direction key divided into a plurality of sections on the touch surface, and a switch installed on a bottom surface of the touchpad. At least one among a drag signal, a tap signal, and a click signal is generated using at least one among the touchpad, the direction key, and the switch.

Claims

1. A display system input device comprising:

a touchpad including a touch surface;

a direction key divided into a plurality of sections on the touch surface; and

a switch installed on a bottom surface of the touchpad,

wherein at least one among a drag signal, a tap signal, and a click signal is generated using at least one among the touchpad, the direction key, and the switch.

2. The display system input device of claim 1, wherein the direction key is divided into an upper section, a lower section, a left section, and a right section to move a pointer in up, down, left, and right directions.

3. The display system input device of claim 1, further comprising a selection key divided from the direction key to generate a selection signal,

wherein, when the selection key is selected, a selection key at coordinates of the pointer displayed on a display unit is actuated.

4. The display system input device of claim 1, wherein, when dragging is performed from a location on the touch surface to another location on the touch surface, the drag signal is generated to move a cursor displayed on a display unit,

when one of the upper, lower, left, and right sections of the direction key is clicked, the click signal is generated to actuate the direction key, and

when a location on the touch surface is tapped, the tap signal is generated to perform scrolling in up and down directions or left and right directions.

5. The display system input device of claim 4, wherein, after the cursor is moved on the display unit by generating the drag signal, the clicking or the tapping is continuously performed to actuate the direction key or perform scrolling.

6. The display system input device of claim 4, wherein, after the direction key is actuated or scrolling is performed, dragging is performed at least once to move the cursor on the display unit.

7. The display system input device of claim 4, wherein, after the direction key is actuated or scrolling is performed, dragging is performed by a predetermined length or more to move the cursor on the display unit.

8. The display system input device of claim 4, wherein whether a set time period passes is determined after the cursor is moved on the display unit,

wherein if the set time period passes, the direction key is actuated when the clicking is performed, and

if the set time period does not pass, a selection key at coordinates of the cursor is actuated when the clicking is performed.

9. The display system input device of claim 4, wherein, after the direction key is actuated, whether a set time period passes is determined,

wherein if the set period time passes, the scrolling is performed when the tapping is performed, and

if the set period time does not pass, a selection key at coordinates of the cursor on the display unit is actuated when the tapping is performed.

10. The display system input device of claim 4, wherein, after the scrolling is performed, the cursor is moved on the display unit when the dragging is performed, and the direction key is actuated when the clicking is performed.

11. The display system input device of claim 1, wherein the switch generates the click signal when an external downward force is applied to the touchpad at a reference level or more.

12. The display system input device of claim 1, further comprising a restoration unit configured to elastically support the bottom surface of the touchpad in an up direction.

13. An input method performed by a display system input device, comprising:

performing a cursor movement operation to move a cursor displayed on a display unit when dragging is performed from a location on a touch surface of a display system input device to another location on the touch surface, wherein the display system input device includes a touchpad including the touch surface, a direction key divided into a plurality of sections on the touch surface, and a switch installed on a bottom surface of the touchpad;

performing a direction key actuation operation to actuate the direction key when one of the plurality of sections of the direction key on the touchpad is clicked; and

performing a scroll actuation operation to perform scrolling in up and down directions or left and right directions when a location on the touch surface of the touchpad is tapped.

14. The input method of claim 13, further comprising performing a selection key actuation operation to actuate a selection key at coordinates of a pointer displayed on the display unit when a selection key additionally formed on the touch surface of the touchpad is selected.

15. The input method of claim 13, wherein, after a cursor movement operation is performed by performing the dragging, the clicking or the tapping is continuously performed to perform the direction key actuation operation or the scroll actuation operation.

16. The input method of claim 13, wherein, after the direction key actuation operation or the scroll actuation operation is performed, touch-dragging is performed at least once to perform the cursor movement operation.

17. The input method of claim 13, wherein, after the direction key actuation operation or the scroll actuation operation is performed, the dragging is performed by a predetermined length or more to perform the cursor movement operation.

18. The input method of claim 13, further comprising performing a set time period determination operation to determine whether a set time period passes, after the cursor movement operation is performed,

wherein if it is determined in the set time period determination operation that the set time period passes, the direction key actuation operation is performed when the clicking is performed, and

if it is determined in the set time period determination operation that the set time period does not pass, a selection key actuation operation is performed to actuate a selection key at coordinates of the cursor displayed on the display unit when the clicking is performed.

19. The input method of claim 13, wherein, after the direction key actuation operation is performed, a set time period determination operation is performed to determine whether a set time period passes,

wherein if it is determined in the set time period determination operation that the set time period passes, the scroll actuation operation is performed when the tapping is performed, and

if it is determined in the set time period determination operation that the set time period does not pass, a selection key actuation operation is performed to actuate a selection key at coordinates of a pointer displayed on the display unit when the tapping is performed.

20. The input method of claim 13, wherein, after the scroll actuation operation is performed, the cursor movement operation is performed when the dragging is performed, and the direction key actuation operation is performed when the clicking is performed.
