3D POINTING DEVICE WITH UP-DOWN-LEFT-RIGHT MODE SWITCHING AND INTEGRATED SWIPE DETECTOR

摘要

A 3D pointing device for use with a content delivery system is provided. The pointing device can operate in one of at least one of two modes: a first 3D or scrolling mode, and a second non- 30 mode that can also be referred to as an up-down-left-right (UDLR) mode. The pointing device can include one or more directional sensors, to provide orientation and movement information. For either of the at least two modes, an optical finger navigation module is provided that can detect movement of a user's finger or object across its screen, and provides a predetermined threshold that must be exceeded before movement information is generated from the OFN module. The pointing device can generate scroll and UDLR commands based on the information from the orientation and movement sensors, as well as the OFN module, or can provide the information from the orientation and movement sensors to a user interface that can generate the appropriate scrolling or UDLR commands for use by the content delivery system.
