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. ## Claims ### Claim 1 A method for managing a computer user interface device, the method comprising: establishing a wireless communication link between a computer user interface device and a first personal computer system;
