Interactive 360-Degree Glasses-Free Tabletop 3D Display
summary
An interactive glasses-free tabletop 3D system reproduces 360° autostereoscopic and horizontal plus vertical motion parallax for multiple users by using linear blending across a sparse projector array — a working prototype uses 60 projectors (about 1/5 previous counts) onto a 1,200 mm screen formed as a spatially imaged iris plane, while a 360-degree camera with OpenPose tracks head height to switch virtual viewpoints; prototype demos succeed but show hotspots, shadows and occasional tracking failures.
