- In case this has not been mentioned yet, the ACM SIGGRAPH Vol. 24, March
- 1990 has many interesting papers on virtual reality. The one I want to
- point out describes a 200 update-per-second helmet tracker that uses
- cameras and LEDs mounted on the ceiling. This is a significant speed up
- over the magnetic based system that is used in currently available VR
- systems. The paper is "A Real-time Optical 3D Tracker for Head-mounted
- Display Systems" by Jih-fang Wang, Vernon Chi and Henry Fuchs of University
- of North Carolina.
-
- I tried out the VPL system at an open house last year and speeding up
- the tracking seems to be very important; the magnetic system has about 5
- updates per second which makes hand-eye coordination difficult.
