OrbeVR is a handheld spherical display based on multi-projection technology. It displays images projected by multiple pico-projectors installed inside the sphere. The infrastructure tracks the positions of the user and the display, and renders head-coupled perspectives with stereoscopic depth cues.

Presenting the design-and-build process of a re-imaged volumetric display that enables mid-air interaction with 3D floating objects. The talk discusses interaction techniques that provide haptic feedback at exterior contours and mitigate occlusion conflicts during direct manipulation based on hand position relative to interior content.
