| Abstract: |
Stereoscopic eyewear (10) enables a viewer to see a three dimensional image from a two dimensional image which is projected or displayed on a screen. The eyewear may be coordinated with the two dimensional image either with a signal transmitted through a cable (40) or with an infrared (IR) transmitter (200, 201) and receiver. The IR transmitter may include two sources of IR light to increase the likelihood of reception by the transmitter. The IR transmitter may have a curved bottom (202) covered with Velcro(TM) material (203) for attachment to another piece of Velcro(TM). The curved bottom in combination with the Velcro(TM) enables control of the orientation of the IR transmitter. When the eyewear is connected via a cable, guide bars (61, 62) or a cable loop (42, 43, 44) can be included to provide strain relieve. The shutter or lens of the eyewear may be made from a liquid crystal cell (11L, 11R). For example, a five sided twisted nematic cell having five sides oriented at 10° cooperating a swept back frame to provide a modern streamline look fore the eyewear.
