Paper Abstract

Motion parallax and binocular disparity are two compelling visual cues for the viewer which enhance depth perception as well as perceived display real-estate. Very low lag between viewer's movements and display generation is vital. The lack of practical, low-cost viewer position-dependent display generation capability has precluded the application of these cues from use in routine compute graphical user interfaces (GUIs). While modern desktop computer GUIs and their applications demand increasingly more display real estate for effective user multitasking or for simultaneous display of data, conventional display device size and resolutions have increased only gradually, requiring manual manipulation of the desktop interface as the only alternative. The continued rapid decline in memory prices and rise in memory performance has resulted in a new balance. Cost per pixel of the display device significantly outweighs the cost per pixel of the memory device employed in conventional display generation subsystems. This balance suggests another alterative. This paper presents the Parallax Engine, a display generation architecture that facilitates these two cues for monoscopic and stereoscopic displays.
