3D Interaction With and From Handheld Computers

3D user interfaces (3DUI) aim to enhance the user performance of 3D interactive tasks. In this paper we focus on the bridges between 3DUIs and handheld computers, following two directions. First, 3DUIs must be developed for efficient interaction with embedded 3D applications. Second, handheld computers can be useful for distant interaction with large displays in collaborative 3D applications. We propose a new 3 DOF interface for interaction with 3D environments for these two directions. This interface is based on the analysis of the video stream coming from the embedded cameras for bimanual interaction with and from handheld computers.
