Spheree

Abstract

We constructed a personal, spherical, multi-projector perspective-corrected rear-projected display called Spheree. Spheree uses multiple calibrated pico-projectors inside a spherical display with content rendered from a user-centric viewpoint. Spheree uses optical tracking for head-coupled rendering, providing parallax-based 3D depth cues. Spheree is compact, supporting direct interaction techniques. For example, 3D models can be modified via 3D interactions on the sphere, providing a 3D sculpture experience.
