Superiority of a Handheld Perspective-Coupled Display in Isomorphic Docking Performances
summary
A controlled study with 20 participants and 8,000 dockings compares four isomorphic setups (Phantom Omni, tangible prop, SDK2 HMD, and a handheld perspective‑coupled display rendered with stereoscopic projection and OptiTrack tracking) using a 15 cm sphere input and five target IDs. Results show HPCD 17% faster than HMD, HPCD yields about +1 byte/s throughput, prop beats Phantom by ~20%, and HMD beats prop by ~12%. The work also introduces a 6 DOF index of difficulty (ET) combining translational and rotational tolerance.
