veBall (patent pending) - The goal of this project is to develop a proof-of-concept 3D input device for manipulating virtual objects in 3D applications. The proposed device (veBall) is intended for use by the non-dominant hand of the user in a desktop-based 3D modeling environment with conventional, large format projection, or immersive displays. The dominant hand of the user is free to operate a conventional 2D pointing device such as a mouse or a stylus.
The veBall will allow the user to control the orientation, view panning and zooming of the 3D model with the non-dominant hand; at the same time, the dominant hand is free to perform more accurate tasks such as selection, translation, and fine rotation. This interaction model takes advantage of the bi-manual input technique, which has been shown by other researchers to improve user performance and better utilize a user's physical manipulation skills.
