Gigapixel virtual reality employing live superzoom cameras

We present a live gigapixel virtual reality system employing a 360° camera, a superzoom camera with a pan-tilt robotic head, and a head-mounted display (HMD). The system is capable of showing on-demand gigapixel-level subregions of 360° videos. Similar systems could be used to have live feed for foveated rendering HMDs.
