Abstract

A control apparatus to control a page displayed in an electronic device is disclosed. The apparatus includes a motion sensor for detecting the motion of the electronic device to send a plurality of motion parameter of detected points, a processor for receiving the motion parameter to determine tilting angles and a tilting speeds of the electronic device based on the motion parameters and to determine an average tilting speeds by averaging the previous predetermined number tilting speeds, wherein the average tilting speeds are compared with a predetermined speed to determine a content-movement speed.

Claims

1. A control apparatus installed in an electronic device to control a page displayed by the electronic device, the apparatus comprising:

a motion sensor for detecting the motion of the electronic device in respect to a special position to send at least one motion parameter of detected points sequentially;

a processor for receiving the motion parameter to determine a tilting angle and a tilting speed of the electronic device based on the motion parameter and to determine an average tilting speed by averaging the previous predetermined tilting speeds, wherein the average tilting speed is compared with a predetermined speed to determine a content-movement speed; and

a controller to move the page based on the content-movement speed.

2. The apparatus of claim 1, wherein the motion sensor is a 2-axle accelerator, a 3-axle accelerator, a compass sensor or an inclinometer.

3. The apparatus of claim 1, wherein the motion sensor detects the motion of the electronic device once every 1 ms.

4. The apparatus of claim 1, further comprising a stop moving page predetermined speed, wherein when the average tilting speed is less than the stop moving page predetermined speed, the page stops moving.

5. The apparatus of claim 1, wherein when the average tilting speed is larger than the predetermined speed, the page is moved in a second content-movement speed, and when the average tilting speed is less than the predetermined speed, the page is moved in a first content-movement speed, wherein the second content-movement speed is larger than the first content-movement speed.

6. The apparatus of claim 1, wherein the tilting speed is an absolute of a difference between the tilting angles of two adjacent detected points.

7. The apparatus of claim 6, wherein when the difference is a positive value, the page is moved toward a first direction, and when the difference is a negative value, the page is moved toward a second direction.

8. The apparatus of claim 1, wherein the tilting speed is a difference between the tilting angles of two adjacent detected points.

9. The apparatus of claim 8, wherein, when the average titling speed is a positive value, the page is moved toward a first direction, and when the average titling speed is a negative value, the page is moved toward a second direction.

10. The apparatus of claim 1, further comprising a user interface to define the predetermined number and the predetermined speed.

11. A control method to control a page displayed by an electronic device, the method comprising:

detecting the motion of the electronic device in respect to a special position to send at least one motion parameter of detected points sequentially;

receiving the motion parameter to determine a tilting angle and a tilting speed of the electronic device based on the motion parameter;

determining an average tilting speed by averaging the previous predetermined tilting speeds;

comparing the average tilting speed with a predetermined speed to determine a content-movement speed; and

moving the page based on the content-movement speed.

12. The method of claim 11, wherein the motion sensor is a 2-axle accelerator, a 3-axle accelerator, a compass sensor or an inclinometer.

13. The method of claim 11, wherein detecting the motion of the electronic device is performed once every 1 ms.

14. The method of claim 11, further comprising to set a stop moving page predetermined speed, wherein when the average tilting speed is less than the stop moving page predetermined speed, the page stops moving.

15. The method of claim 11, wherein when the average tilting speed is larger than the predetermined speed, the page is moved in a second content-movement speed, and when the average tilting speed is less than the predetermined speed, the page is moved in a first content-movement speed, wherein the second content-movement speed is large than the first content-movement speed.

16. The method of claim 11, wherein further comprising to set another predetermined speeds to define a plurality of speed segment corresponding to a plurality of content-movement speed, wherein the content-movement speeds are equal to the corresponding predetermined speeds.

17. The method of claim 16, wherein the content-movement speeds are proportional to the average tilting speed.

18. The method of claim 11, wherein the tilting speed is an absolute of a difference between the tilting angles of two adjacent detected points.

19. The method of claim 18, wherein when the difference is a positive value, the page is moved toward a first direction, and when the difference is a negative value, the page is moved toward a second direction.

20. The method of claim 11, wherein the tilting speed is a difference between the tilting angles of two adjacent detected points.

21. The method of claim 20, wherein when the average tilting speed is a positive value, the page is moved toward a first direction, and when the average tilting speed is a negative value, the page is moved toward a second direction.

22. The method of claim 11, further comprising to define the predetermined number and the predetermined speed.
