Abstract

The present invention relates to a method and apparatus of view window scrolling applied in a touch-control information apparatus, the touch-control information apparatus utilizing an input device or finger of a user for an input signal. The present invention controls movement of a view window page according to a scrolling signal generated by the input device or the finger moving across a touch panel corresponding to the view window page. No characters or images are highlighted in response to the scrolling signal. After receiving the scrolling signal, the touch-control information apparatus calculates a vertical displacement and a horizontal displacement of a start coordinate value and an end coordinate value, and then moves the view window page in a vertical direction and a horizontal direction according to the calculated vertical displacement and horizontal displacement.

Claims

1. A method of view window scrolling applied in a touch-control information apparatus, the touch-control information apparatus capable of displaying at least one view window page, and the touch-control information apparatus comprising a touch panel for inputting signals into the touch-control information apparatus via an input device or a finger of a user, the method comprising the steps of:

(A) receiving a scrolling signal generated by the inputting device or the finger moving on the touch panel corresponding to a current view window, wherein the scrolling signal stores a start coordinate value and an end coordinate value for the movement of the inputting device or the finger on the touch panel;

(B) calculating a vertical displacement and a horizontal displacement of the start coordinate value and the end coordinate value; and

(C) moving the view window in a horizontal direction according to the horizontal displacement and moving the view window in a vertical direction according to the vertical displacement.

2. The method as claimed in claim 1 further comprising a step before the step (A) of:

starting a transform means to transform the touch-control information apparatus from a preset mode to a mode for receiving the scrolling signal.

3. The method as claimed in claim 2, wherein in the mode for receiving the scrolling signal, when the inputting device or the finger drags on the touch panel no characters or images are highlighted.

4. The method as claimed in claim 1, wherein when the movement of the inputting device or the finger exceeds an edge of the touch panel of the view window page, the end coordinate value is set to a corresponding coordinate value of the inputting device or the finger passing an edge of the view window page.

5. The method as claimed in claim 1, wherein in the step (C), when the horizontal displacement exceeds a moveable horizontal distance of the view window page, the view window page moves in a horizontal direction according to the moveable horizontal distance.

6. The method as claimed in claim 1, wherein in the step (C), when the vertical displacement exceeds a moveable vertical distance of the view window page, the view window page moves in a vertical direction according to the moveable vertical distance.

7. The method as claimed in claim 1, wherein the view window page further comprises a horizontal direction scrollbar or a vertical direction scrollbar, and the inputting device or the finger drags the scrollbar to move the view window page in a horizontal direction or a vertical direction.

8. The method as claimed in claim 1, wherein the touch-control information apparatus is a tablet PC.

9. The method as claimed in claim 1, wherein the inputting device is a pen.

10. The method as claimed in claim 1, wherein the view window page contains webpage content displayed by a browser.

11. The method as claimed in claim 10, wherein when a website indicated by a browser comprises a plurality of frames, webpage content of each frame is a view window page.

12. The method as claimed in claim 1, wherein the view window page contains document content displayed by word processing software.

13. A touch-control information apparatus for displaying at least one view window page, the touch-control information apparatus comprising a touch panel, the touch-control information apparatus capable of inputting a signal by a user via an input device or a finger, and containing the flowing means:

(A) means for receiving a scrolling signal generated by the inputting device or the finger moving on the touch panel corresponding to a current view window, wherein the scrolling signal stores a start coordinate value and an end coordinate value for the movement of the inputting device or the finger on the touch panel;

(B) means for calculating a vertical displacement and a horizontal displacement of the start coordinate value and the end coordinate value; and

(C) means for moving the view window in a horizontal direction according to the horizontal displacement and moving the view window in a vertical direction according to the vertical displacement.

14. The touch-control information apparatus as claimed in claim 13 further comprising a means for starting a transform means to transform the touch-control information apparatus from a preset mode to a mode for receiving the scrolling signal.

15. The touch-control information apparatus as claimed in claim 14, wherein in the mode for receiving the scrolling signal, when the inputting device or the finger drags on the touch panel no characters or images are highlighted.

16. The touch-control information apparatus as claimed in claim 13 wherein the touch-control information apparatus is a tablet PC.

17. The touch-control information apparatus as claimed in claim 13 further comprising a sensitivity transform means for adjusting a moving speed and/or distance of the view window page.
