The CAT's autostereoscopic display presents a different image to the user's left and right eyes. This produces a 3D image to the user without the necessity of special glasses. In order for the device to seamlessly track a user's head movement we are developing an entirely electronic light shutter, which avoids the otherwise unavoidable reliance on slow-moving mechanical devices to manipulate the display lights. The following demonstrates an

Entirely Electronic Autostereoscopic Display:

Instructions:
Adjust the character's head by dragging your mouse, click on the left turn and right turn labels, or click on STEP or CYCLE.

Notice how the shutter lines get thinner as the user's head moves further away from the screen. Also notice how the shutter line spacing varies as the user turns his head to the side. You can learn about the principle behind this HERE.

The autostereoscopic display was developed by Ken Perlin, Chris Poultney, Joel S Kollin, Salvatore Paxia, and Nathan Wardrip-Fruin.
