TWISTER III: A panoramic autostereo display for motion pictures

TWISTER (Telexistence Wide-angle Immersive STEReoscope) is a panoramic autostereo display designed for face-to-face telecommunications. This device works as a cylindrical display by rotating multiple display units around an observer and by presenting time-varying patterns. Panoramic autostereo vision is achieved by using a "rotating parallax barrier" method, the effectiveness of which was already reported. To date, we have succeeded in presenting panoramic stereo motion pictures using the third prototype TWISTER III. Its design, implementation, and evaluation are reported, and past and present problems are enumerated. The discussion includes psychophysical experiments conducted to evaluate the display performance. Issues on constructing panoramic stereo images are also described.
