Abstract

A touch control device comprises a touchpad, a display unit and a processing unit. The touchpad detects a touch gesture and generates information corresponding to the touch gesture. The processing unit includes a page display module, a gesture processing engine, a gestures determining module and a control module. The gesture processing engine determines whether the information corresponding to the touch gesture includes the information of at least three fingers touch the touchpad. The gestures determining module determines whether the touchpad detects a scrolling gesture made by one of the fingers when the information corresponding to the touch gesture includes the information of at least three fingers touch the touchpad. The control module scrolls the page or image displayed on the display unit according to the scrolling gesture when the touchpad detects the scrolling gesture made by at least one of the fingers.

Claims

1. A touch control device, comprising:

a touchpad detecting a touch gesture and generating information corresponding to the touch gesture;

a display unit; and

a processing unit electrically connected to the touchpad and the display unit, wherein the processing unit includes;

a page display nodule driving the display unit to display a page;

a gesture processing engine determining whether the information corresponding to the touch gesture includes the information of at least three fingers touch the touchpad;

a gestures determining module determining whether the touchpad detects a scrolling gesture made by one of the fingers when the information corresponding to the touch gesture includes the information of at least three fingers touch the touchpad; and

a control module scrolling the page or image displayed on the display unit according to the scrolling gesture when the touchpad detects the scrolling gesture made by at least one of the fingers.

2. The touch control device according to claim 1, wherein the processing unit further includes:

an enabling module determining whether the information corresponding to the touch gesture includes the information that the at least three fingers do not move before the gestures determining module operates,

wherein the gestures determining module is triggered to execute when the information corresponding to the touch gesture includes the information that the at least three fingers do not move.

3. The touch control device according to claim 1, wherein the processing unit further includes:

a moving determining module determining whether only one of the at least three fingers moves on the touchpad;

wherein the gestures determining module is triggered to execute when the moving determining module determines only one of the at least three fingers moves on the touchpad.

4. The ouch control device according to claim 1, wherein the control module further includes:

a track determining unit determining the direction of the sliding track formed by the scrolling gesture, wherein the control module scrolls the page or image displayed on the display unit according to the direction of the sliding track.

5. The touch control device according to claim 4, wherein the direction of the sliding track is upward, downward, leftward or rightward.

6. A touch control processing method, applied to a touch control device, wherein the touch control device comprises a touchpad and a display unit, the touch control processing method comprising:

(a) detecting a touch gesture via the touchpad and generating information corresponding to the touch gesture;

(b) determining whether the information corresponding to the touch gesture includes at least three fingers touch the touchpad;

(c) determining whether the touchpad detects a scrolling gesture made by one of the fingers when the information corresponding to the touch gesture includes the at least three fingers touch the touchpad; and

(d) scrolling the page or image displayed on the display unit according to the scrolling gesture when the touchpad detects the scrolling gesture made by one of the at least three fingers.

7. The touch control processing method according to claim 6, further comprising:

determining whether the information corresponding to the touch gesture includes the information that the at least three fingers do not move before the execution of the step (c); and

triggering step (c) to execute when the information corresponding to the touch gesture includes the information that the at least three fingers do not move.

8. The touch control processing method according to claim 6, further comprising:

determining whether only one of the three fingers moves on the touchpad before the execution of the step (c), and

triggering step (c) to execute when only one of the three fingers moves on the touchpad.

9. The touch control processing method according to claim 6, wherein the step (d) further includes:

determining the direction of the sliding track formed by the scrolling gesture; and

scrolling the page or image displayed on the display unit according to the direction of the sliding track.

10. The touch control processing method according to claim 9, wherein the direction of the sliding track is upward, downward, leftward or rightward.
