Autostereo Displays: 3D without Glasses

Neil Dodgson

(University of Cambridge)

3D displays which use glasses have not gained wide acceptance. Autostereo displays provide 3D perception without the need for special glasses or other head gear. I will look briefly at conventional "3D with glasses" systems before introducing the concept of an autostereo display. I will then go on to discuss the types of autostereo display and the mechanisms by which an autostereo display can be implemented.

Three basic technologies exist to make autostereo displays: spatial multiplex, multi-projector and time-sequential. These can be used to make two types of useful device: two-view, head-tracked displays; and multi-view displays. The former tend to be single-viewer systems while the latter can support multiple viewers. The latter tend to require more processing power because they have more views than the former.

Research in the Computer Laboratory and Department of Engineering at Cambridge has produced a time-sequential, multi-view display. This is currently being commercialised by a Cambridge company: Autostereo Systems. I will report on the current state of the "Cambridge Display" and conclude with some discussion of future research directions in both display technology and image rendering.
