Icuiti's VR920, which won the 2007 CES "innovations award", creates a feeling of watching a 62-inch screen from nine feet away. The picture displays in 640x480 and it comes with a built in microphone and head tracker.
The technology is a "virtual reality" version of similar headsets that it has designed for watching videos, such as the Icuiti: AV230 which came out in November. The AV230 could only manage looking like a 44" home theatre.
The VR920 certainly is a step up from the nightmare VR specs I tried at a show once, but then again that is not difficult. There is a picture here. ยต
