Abstract
Autostereoscopic displays effectively 'steer' different image-bearing bundles of light rays to the two eyes of the observer(s). Typically, each observer has to find an imaginary point or line in space upon which to place her nose, or an active system tracks a single observer, aiming the imaginary point or line toward her nose via some sort of face tracking scheme. This paper describes a system of the second type that is specifically adapted to accommodate several arbitrarily-located viewers while maintaining good optical isolation of a stereoscopic pair of images, and while registering them so that the consonance of accommodation and convergence occurs at the front surface of the display for maximum comfort during interaction.
