Abstract
Abstract A head mounted display for presentation of video information includes a virtual raster display unit, an attachment mechanism for attaching the display unit to the head of the user, a support member connected to the attachment mechanism for supporting the display unit within the user's field of vision, and a remote signal source for providing power, timing, control signals and display information to the display system. The head attachment mechanism can be symmetrically designed to allow positioning of the display unit in front of either of the viewer's eyes, or the attachment mechanism may be eliminated completely and the support member and display unit attached directly to a conventional helmet or the user's eyeglasses.
