A Passive Stereo Virtual Reality System Using Circularly Polarized High Resolution LCD Panels
The ImmersaDesk4™ (IDesk4™) is built from 2 Apple 30” 2560 x 1600 LCD panels mounted with quarter-wave plates in front of the LCD panels to achieve circular polarization. The LCD panels are bisected by a half-silvered mirror which reverses the polarization of the top LCD panel. The circular polarization facilitates viewing stereoscopic images even while the head is tilted.
An optional 3D position and orientation tracking system can be attached to allow the computer graphics to project the correct viewer-centered stereoscopic imagery based on the user’s head position and orientation.
