Alert reader on Yahoo Message board found this article. Interesting and looks like Microvision's fingerprints to me.
Today Valve Corp. (Bellevue, Wash.) has a VR headset that is "10 generations ahead anything available today", according to McCauley, by using more accurate head tracking by replacing the camera Oculus uses with a rotating motor driven line-laser. The line laser is essentially a gigantic laser housing a motor spinning a curved mirror mounted on the wall across from the user, that scans across head mounted IR detectors to determine how far away the head is by measuring the time between IR sensor intercepts.
At McCauley Labs they will replace the bulky moving laser mechanism, with a MEMS mirror and a line-laser (or alternatively a 2-axis MEMS mirror and a point laser to raster scan in the manner of a one-mirror pico projector) to perform the same kind of head location geometry and calculation as the Valve System, but micro-miniaturized.
The system will also turn off the backlight for imperceptible periods between frames, to prevent the blurring that otherwise contributes to simulator sickness, making the result VR experience as real as reality itself, or so McCauley claims.
