GESTURE RECOGNITION METHOD AND TOUCH SYSTEM INCORPORATING THE SAME
First Claim
Patent Images
1. An event generation method comprising the steps of:
- capturing images using image devices looking generally across a pointer input region;
processing the captured images to detect relative movement of multiple pointers within said pointer input region; and
generating an event when the detected relative pointer movement represents a gesture.

Abstract
A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.
