ABSTRACT:
A head-mounted projection display system featuring a beam splitter displays a simulated environment to an observer using a light-weight, low-cost, head-mounted projector and a retro-reflective screen. The display system optically co-locates the projector with the observer's eyes for effective use of either curved or flat retro-reflective screens. High screen gain achieved by the head-mounted projection display system makes inexpensive projector sources such as a cathode ray tube feasible. An alternative head-mounted display system also incorporating beam splitters produces an unlimited horizontal field of view, but with limited binocular overlap, while using multiple head-mounted image sources for each eye. A method of providing the head-mounted display system also is disclosed.
