Abstract

A scrolling control method for a touch device, comprising the steps of: selecting a scrolling region on the touch device; defining at least two sections on the scrolling region; detecting touches of an object on at least two different sections successively, the time span between the touches of the object on the two sections corresponding a displacement; and controlling a scroll bar to scroll the displacement according to the operation of the object on a window of the touch device.

Claims

1. A scrolling control method for a touch device, comprising:

selecting a scrolling region on the touch device;

defining at least two sections on the scrolling region;

detecting touches of an object on at least two different sections successively, the time span between the touches of the object on the two sections corresponding to a displacement; and

controlling a scroll bar to scroll the displacement corresponding to the time span.

2. The method of claim 1, wherein at least two sections are disposed in a horizontal direction.

3. The method of claim 1, wherein at least two sections are disposed in a vertical direction.

4. The method of claim 1, wherein the displacement is in a specific direction, which is determined by the relative location of the at least two sections.

5. The method of claim 4, wherein the specific direction comprises a horizontal direction.

6. The method of claim 4, wherein the specific direction comprises a vertical direction.

7. The method of claim 4, wherein the specific direction is selected from a group consisting of a horizontal direction, a vertical direction, an upper right direction, a bottom right direction, an upper left direction, and a bottom left direction.

8. The method of claim 1 further comprising:

determining whether the time span between the touches on the two sections is greater than a first reference time and less than a second reference time;

if the time span is greater than the first reference time and less than the second reference time, performing the controlling step;

if the time span is not between the first reference time and the second reference time, detecting another touch of the object on the touch device.

9. A scrolling control device comprising a touchpad comprising a scrolling region, wherein a time span between touches of an object on two sections of the scrolling region corresponds to a scrolling displacement when the two sections are touched successively.

10. The device of claim 10, wherein the scrolling displacement is in a specific direction, which is determined by the relative location of the two sections.

11. The device of claim 10, wherein the specific direction comprises a horizontal direction.

12. The device of claim 10, wherein the specific direction comprises a vertical direction.
