Gesture Recognition Development for the Interactive Datawall

Abstract

Hand gestures provide a useful interface for humans to interact with not only other humans but also machines. Especially for a high degree-of-freedom manipulation tasks such as the operation of 3D objects in virtual scenes, the traditional interface composed of a keyboard and mouse is neither intuitive nor easy to operate. In collaborative environments using large screen displays for display of both 3D and 2D information, participants would benefit greatly from an interface that is unencumbered, natural, and effective for communication during discussions. The goal of this project was to investigate the feasibility of implementing an image triangulation technique to track the position of a passive device pointing towards a large screen display.
