Implementation of Auto-stereoscopic 3D Display for Tabletop Tasks

Abstract

We propose a novel auto-stereoscopic 3D display of 360° optimized for tabletop tasks. The display employs a cylindrical- or a conical-shaped optical device that has a directional optical characteristic and circularly arranged projectors. Those devices are installed underneath the table not to obstruct the working space. One of the novelties of the proposed method is forming a ring-shaped viewing area above the table. When users look in this area, they can observe individual 3D images from each direction with correct perspective on the table such as a centerpiece.
