Title:
- Spheree: A 3D Perspective-Corrected Interactive Spherical Scalable Display

Abstract:
We constructed a personal, spherical, multi-projector perspective-corrected display called Spheree. Spheree uses multiple calibrated pico-projectors illuminating a spherical screen with perspective-corrected 3D content. The pico-projectors are mounted inside the spherical display surface, creating a seamless backprojected display. Spheree uses optical tracking to support head-coupled rendering to provide motion parallax-based 3D depth cues. Spheree is relatively compact and supports direct interaction techniques. For example, existing models can be modified via a 3D interaction interface on the sphere, providing a 3D sculpture experience, and the final models can be exported or printed on a 3D printer.
Other related 3D displays include: 1. pCubee [Stavness et al. ], a cubic fish-tank VR device with interaction based on physical motion; it does not use touch, is not scalable, and has bezels cause disruptive scene occlusion; 2. SnowGlobe [Bolton et al. 2011], a spherical display with a single stereo 3D projector and a hemispherical mirror; it has non-uniform resolution and a blind spot from the mirror; 3. Other projection spheres1 that use a single projector with a fish-eye lens, but do not scale to high-resolution.
