Abstract

An attachment for a projected head mounted display redirects images designed to be projected on retroreflective screens directly back into the eyes of a user. This permits, for example, the head mounted display to be switched from an augmented reality mode to a virtual reality mode. The attachment can be engaged or disengaged from the head mounted display. The attachment includes a freeform prism.
