Qoom: An Interactive Omnidirectional Ball Display
summary
Qoom is a lightweight, impact‑resistant spherical display that actually works: a physical rubber ball wrapped in retroreflective material houses a central circuit board and transmits touch and rotation data wirelessly while six motion‑capture cameras and multiple external projectors render mapped images with a prediction algorithm. The prototype uses 6 motion‑capture cameras, 32 capacitance panels and a gel posture sensor, supports touch, rotation, bouncing (home), and throwing (pass/reset), runs Pano Ball/Pano Chat/calendar/tree and a face‑matching game, and demos well but depends on room projectors, suffers occlusion and low touch resolution.
