STATE-BASED APPROACH TO GESTURE IDENTIFICATION

摘要

A method and apparatus for identifying user gesture includes a touch sensor (500) for determining contact information (750) that describes locations at which a user contacts a touch sensitive surface corresponding to a display (2500). The touch sensor (500) provides the contact information to a gesture identification module (1000) which uses state information to identify a user gesture and, responsive thereto issues an associated display command (1500) to a display control module. The display control module (2000) updates the display (2500) based on display commands received from the gesture identification module (1000).
