Abstract

The present invention relates to controlling a presentation device coupled to the presentation system using a user interface generated by a computing system, the user interface including one or more regions which vary in size based on whether the user interface is being displayed, the user interface accepting input from a pointing device to control the presentation device.

Claims

1. A user interface for use in controlling a presentation generated by a presentation system, the presentation system comprising a computing system and a projection device, the projection device is capable of receiving input from a plurality of input sources including the computing system, the user interface comprising:

at least one control region of the user interface, at least one presentation control operation being associated with the control region,

wherein the user interface is modified based on a determination of which one of the plurality of input sources is providing an input signal to the projection device.

2. A user interface according to claim 1, wherein the control region is enlarged if it is determined that the one of the plurality of input sources is other than the computing system.

3. A user interface according to claim 1, wherein the control region is moved if it is determined that the one of the plurality of input sources is other than the computing system.

4. A user interface according to claim 3, wherein the control region is moved to one or more corners of the user interface.

5. A user interface according to claim 3, wherein the control region is moved to at least one of a top region and a bottom region of the user interface.

6. A user interface according to claim 1, wherein other regions of the user interface are disabled in the user interface if it is determined that the one of the plurality of input sources is other than the computing system.

7. A user interface according to claim 1, wherein the user interface includes at least one region other than the control region, the control region and the at least one other region are buttons of a toolbar, wherein the control region button is enlarged and the other buttons are disabled if it is determined that the one of the plurality of input sources is other than the computing system.

8. A user interface according to claim 1, wherein the at least one presentation control operation is changed based at least in part on which one of the plurality of input sources is providing an input signal to the projection device.

9. A user interface according to claim 1, wherein the control region corresponds to a presentation control operation that causes the computing system to be used as the input source.

10. A user interface according to claim 1, wherein the input sources to the projection device further comprise at least one of video cassette recorder, television broadcast, digital video disk player, digital camera, removable storage media reader, scanner, TV-phone, another computing system.

11. A user interface according to claim 1, wherein mirroring cursor movement is suspended while an input source other than the computing system is providing input to the projection device.

12. A user interface according to claim 1, wherein the input source is other than the computing system, and wherein the presentation control command commands the projection device to control the input source.

13. A user interface according to claim 12, wherein the presentation control command causes the projection device to advance a presentation.

14. A user interface according to claim 13, wherein the presentation comprises still images, wherein the presentation control command causes the projection device to advance the presentation by one or more image frames.

15. A user interface according to claim 13, wherein the presentation comprises animations, and wherein the presentation control command causes the projection device to start an animation.

16. A user interface according to claim 12, wherein the presentation control command causes the projection device to reverse a presentation by one or more image frames.

17. A user interface according to claim 12, wherein the presentation control command causes the projection device to pause a presentation.

19. A method according to claim 18, wherein the control region is enlarged if it is determined that the one of the plurality of input sources is other than the computing system.

20. A method according to claim 18, wherein the control region is moved if it is determined that the one of the plurality of input sources is other than the computing system.

21. A method according to claim 20, wherein the control region is moved to one or more corners of the user interface.

22. A method according to claim 20, wherein the control region is moved to at least one of a top region and a bottom region of the user interface.

23. A method according to claim 18, wherein other regions of the user interface are disabled in the user interface if it is determined that the one of the plurality of input sources is other than the computing system.

24. A method according to claim 18, wherein the user interface includes at least one region other than the control region, the control region and the at least one other input region are buttons of a toolbar, wherein the control region button is enlarged and the other buttons are disabled if it is determined that the one of the plurality of input sources is other than the computing system.

25. A method according to claim 18, wherein the at least one presentation control operation is changed based at least in part on which one of the plurality of input sources is providing an input signal to the projection device.

26. A method according to claim 18, wherein the control region corresponds to a presentation control operation that causes the computing system to be used as the input source.

27. A method according to claim 18, wherein the input sources to the projection device further comprise at least one of video cassette recorder, television broadcast, digital video disk player, digital camera, removable storage media reader, scanner, TV-phone, another computing system.

28. A method according to claim 18, wherein mirroring cursor movement is suspended while an input source other than the computing system is providing input to the projection device.

29. A method according to claim 18, wherein the input source is other than the computing system, and wherein the presentation control command commands the projection device to control the input source.

30. A method according to claim 29, wherein the presentation control command causes the projection device to advance a presentation.

31. A method according to claim 30, wherein the presentation comprises still images, wherein the presentation control command causes the projection device to advance the presentation by one or more image frames.

32. A method according to claim 30, wherein the presentation comprises animations, and wherein the presentation control command causes the projection device to start an animation.

33. A method according to claim 29, wherein the presentation control command causes the projection device to reverse a presentation by one or more image frames.

34. A method according to claim 29, wherein the presentation control command causes the projection device to pause a presentation.

18. A method for use in a computing system for providing a user interface of a presentation system that includes the computing system and a projection device, the projection device capable of receiving video input from a plurality of input sources including the computing system, the method comprising:

defining a user interface having at least one control region;

determining which one of the plurality of input sources is providing an input signal to the projection device; and

modifying the user interface based on the result of the determining step.

35. An apparatus for providing a user interface of a presentation system, the presentation system including the apparatus and a projection device, the projection device capable of receiving video input from a plurality of input sources including the apparatus which comprises:

a program memory for storing process steps executable to perform a method according to any of claims 18 to 34; and

a processor for executing the process steps stored in said program memory.

36. Computer-executable process steps stored on a computer readable medium, said computer-executable process steps for providing a user interface of a presentation system, the presentation system including a computing system and a projection device, the projection device capable of receiving video input from a plurality of input sources including the computing system, said computer-executable process steps comprising process steps executable to perform a method according to any of claims 18 to 34.
