Abstract

A system and method for managing a user interface resource. Various aspects of the present invention comprise establishing a wireless communication link between a user interface resource and a first system. The user interface resource may, for example, be utilized to communicate user interface information with the first system. An inter-system communication link may be established between the first system and a second system. The user interface resource, or alternative source, may communicate a predetermined signal to the first system. The first system may, for example after receiving the predetermined signal, communicate a hand-off signal to the second system over the inter-system communication link. The hand-off signal may indicate that the user interface resource is to be used with the second system. The second system may establish a wireless communication link with the user interface resource, and the user interface resource may be utilized with the second system.

30. The method of claim 1, wherein the computer user interface device is a video display device with which a personal computer system outputs video information to a user.

31. The method of claim 1, wherein the computer user interface device is an audio speaker device with which a personal computer system outputs audio information to a user.

8. In a first personal computer system, a method for managing a computer user interface device, the method comprising:

establishing a wireless communication link with the computer user interface device;

utilizing the computer user interface device to provide a user interface between the first personal computer system and a user of the first personal computer system;

establishing a second communication link with a second system;

receiving a predetermined signal from the computer user interface device over the wireless communication link; and

in response to receiving the predetermined signal from the computer user interface device, communicating a hand-off signal to the second system over the second communication link, the hand-off signal indicating to the second system that the computer user interface device is to be used to provide a user interface between the second system and a user of the second system instead of to provide a user interface between the first personal computer system and a user of the first personal computer system.

9. The method of claim 8, further comprising, prior to receiving the predetermined signal from the computer user interface device, communicating user interface information with the computer user interface device over the wireless communication link, and wherein the predetermined signal is embedded in the user interface information communicated in a data channel.

10. The method of claim 8, wherein the hand-off signal indicates that the computer user interface device and a second computer user interface device are to be used to provide a user interface between the second system and a user of the second system.

11. The method of claim 8, comprising, prior to receiving the predetermined signal from the computer user interface device, providing a human-perceivable indication that the computer user interface device is being used with the first personal computer system.

12. The method of claim 8, comprising, in response to receiving the predetermined signal from the computer user interface device, providing a human-perceivable indication that the computer user interface device is being used with the second system.
