Abstract

An integrative image system includes an image display, a first input device, a second input device and a host. When at least one key of the first input device is pressed, the first input device sends a control signal to the host to enable the host to compare a characteristic parameter detected by the second input device with a plurality of predetermined rules and to control the image display to execute a corresponding function according to the predetermined rule that the characteristic parameter matches. The present invention further provides an operating method of an interactive image system.

Claims

1. An operating method of an interactive image system, comprising the steps of:

displaying an image on an image display;

continuously pressing at least one key of a first input device to enable an interactive image system to enter a second mode;

acquiring a characteristic parameter with a second input device;

comparing the characteristic parameter with a plurality of predetermined rules; and

updating an image shown by the image display according to the predetermined rule that the characteristic parameter matches.

2. The operating method as claimed in claim 1, wherein the second input device is a mouse;

the characteristic parameter is a velocity, an acceleration and/or a moving direction of the mouse with respect to a surface.

3. The operating method as claimed in claim 2, wherein the predetermined rule is set as the velocity being larger than a threshold, the acceleration being larger than a threshold and/or the moving direction matching a predetermined direction.

4. The operating method as claimed in claim 1, wherein the second input device is an image sensing device;

the characteristic parameter is a gesture, a velocity, an acceleration and/or a moving direction of a pointer acquired by the image sensing device.

5. The operating method as claimed in claim 4, wherein the predetermined rule is set as the velocity being larger than a threshold, the acceleration being larger than a threshold, the moving direction matching a predetermined direction and/or the gesture matching a predetermined gesture.

6. The operating method as claimed in claim 1, wherein before the step of continuously pressing at least one key of a first input device further comprises:

controlling a cursor shown on the image display to a proper position with the second input device.

7. The operating method as claimed in claim 1, wherein the image shown by the image display is updated to show object rotating, object zooming, window zooming, scrolling or page flipping.

8. An operating method of an interactive image system, comprising the steps of:

controlling the interactive image system to enter a second mode with a first input device;

detecting a velocity, an acceleration and/or a moving direction with a second input device;

identifying a rule of the velocity, the acceleration and/or the moving direction; and

controlling an image display to execute a corresponding function according to the rule.

9. The operating method as claimed in claim 8, wherein the second input device is a mouse;

the velocity, the acceleration and the moving direction are a velocity, an acceleration and a moving direction of the mouse with respect to a surface respectively.

10. The operating method as claimed in claim 9, wherein the step of identifying a rule of the velocity, the acceleration and/or the moving direction is to identify whether the velocity is larger than a threshold, whether the acceleration is larger than a threshold and/or whether the moving direction matches a predetermined direction.

11. The operating method as claimed in claim 8, wherein the second input device is an image sensing device;

the velocity, the acceleration and the moving direction are a velocity, an acceleration and a moving direction of a pointer detected by the image sensing device respectively.

12. The operating method as claimed in claim 11, wherein the step of identifying a rule of the velocity, the acceleration and/or the moving direction is to identify whether the velocity is larger than a threshold, whether the acceleration is larger than a threshold and/or whether the moving direction matches a predetermined direction.

13. The operating method as claimed in claim 11, further comprising:

identifying whether a gesture of the pointer matches a predetermined gesture.

14. The operating method as claimed in claim 8, wherein the corresponding function is set as rotating an object shown by the image display, zooming an object or a window shown by the image display, scrolling or flipping pages.

15. The operating method as claimed in claim 8, wherein before the step of controlling the interactive image system to enter a second mode with a first input device further comprises:

controlling a cursor shown on the image display to a proper position with the second input device.

16. An interactive image system, comprising:

an image display;

a first input device, comprising a plurality of keys for being used to input a control signal;

a second input device, configured to acquire a characteristic parameter; and

a host, controlling the image display according to the control signal and the characteristic parameter, wherein when at least one key of the first input device is pressed, the first input device sends the control signal to the host to enable the host to compare the characteristic parameter acquired by the second input device with a plurality of predetermined rules, and to control the image display to execute a corresponding function according to the predetermined rule that the characteristic parameter matches.

17. The interactive image system as claimed in claim 16, wherein the first input device and second input device are wirelessly or electrically coupled to the host.

18. The interactive image system as claimed in claim 16, wherein the second input device is a mouse or an image sensing device.

19. The interactive image system as claimed in claim 18, wherein when the second input device is the mouse, the characteristic parameter is a velocity, an acceleration and/or a moving direction of the mouse with respect to a surface.

20. The interactive image system as claimed in claim 19, wherein the predetermined rule is set as the velocity being larger than a threshold, the acceleration being larger than a threshold and/or the moving direction matching a predetermined direction.

21. The interactive image system as claimed in claim 18, wherein when the second input device is the image sensing device, the characteristic parameter is a gesture, a velocity, an acceleration and/or a moving direction of a pointer detected by the image sensing device.

22. The interactive image system as claimed in claim 21, wherein the predetermined rule is set as the velocity being larger than a threshold, the acceleration being larger than a threshold, the moving direction matching a predetermined direction and/or the gesture matching a predetermined gesture.

23. The interactive image system as claimed in claim 16, wherein the first input device is a keyboard.

24. The interactive image system as claimed in claim 16, wherein the corresponding function is set as rotating an object shown by the image display, zooming an object or a window shown by the image display, scrolling or flipping pages.

25. The interactive image system as claimed in claim 16, wherein the host is integrated in the image display.
