Patent ID: 7735024

Claim:
A method to provide a handheld pointer-based user interface comprising: encoding, at a wireless pointer component, a first human-computer interaction (HCI) signal with a first code to correspond to a first time associated with a first HCI operation; transmitting via a first communication link the first encoded HCI signal from the wireless pointer component to a base component that is operatively coupled to a screen of a display; encoding, at the wireless pointer component, a second HCI signal with a second code to correspond to a second time associated with the first HCI operation; transmitting via the first communication link the second encoded HCI signal from the wireless pointer component to the base component, wherein the first code and the second code differ to indicate a difference between the first time the second time; generating position information associated with the wireless pointer component based on one of the first and second HCI signals; and transmitting via a second communication link the position information from the base component to a processor configured to generate screen information on the screen of the display.
