Abstract
This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content. The optical assembly includes a light transmissive wedge-shaped illumination system with angle selective coatings and an LED lighting system coupled to an edge of the wedge. An angled surface of the wedge directs light from the LED lighting system to uniformly irradiate a reflective image display to produce an image that is reflected through the illumination system to provide the displayed content to the user.
