VizSpace: Interaction in the Positive Parallax Screen Plane

The VizSpace is a physically situated interactive system that combines touch and hand interactions behind the screen to create the effect that users are reaching inside and interacting in a 3D virtual workspace. It extends the conventional touch table interface with hand tracking and 3D visualization to enable interaction in the positive parallax plane, where the binocular focus falls behind the screen so as not to occlude projected images. This paper covers the system design, human factors and ergonomics considerations for an interactive and immersive gesture-based visualization system. Results are presented from a preliminary user study that validates the usability of VizSpace
