Poster: Toward an Interactive Box-shaped 3D Display: Study of the Requirements for Wide Field of View

We propose a graspable box-shaped 3D display as a communication tool that allows multiple users to share and naturally interact with 3D images in face-to-face collaborative tasks. We envision an auto-stereoscopic 3D display featuring glasses- free and multi-viewpoint operation. Users should be able to view multiple faces in the box-shaped display simultaneously and from any direction. We employ the integral photography (IP) method for this purpose. In this paper, we first analyze the requirements for an IP lens allowing simultaneous multi-face viewing of 3D images in such a display. Consequently, we find that a mininum 120-degree field of view is necessary. Then, we design and prototype an IP lens that provides such a wide field of view. Visual inspection of the generated 3D images confirm the possibility of simultaneous multiple- face viewing with the proposed display.
