Science based Design Decision Making for Virtual Reality
summary
Compilation of 2.5 years of weekly interviews distills actionable claims: VR needs ~90 fps and uses asynchronous Time Warp/Space Warp to hide judder; locomotion hacks include redirected walking, walk-in-place, teleportation, cockpit framing, speed streaks and a rendered nose (reducing sickness ~10–20%); display fixes are anti–screen-door panels, Half Dome focal prototypes and foveated rendering (≈50% GPU savings); experimental hardware includes galvanic vestibular stimulation for perceived G‑forces and dual‑screen or light‑field focal solutions.
