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, and an LED lighting system coupled to a light transmissive illumination system of the optical assembly. An optical imperfection of the illumination system 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.

Claims

1. A system, comprising:

an interactive head-mounted eyepiece worn by a user, wherein the eyepiece includes an optical assembly through which the user views a surrounding environment combined with displayed content, an integrated processor for handling content for display to the user, and an integrated image source for introducing the content to the optical assembly, and

an LED lighting system coupled to a light transmissive illumination system of the optical assembly;

wherein an optical imperfection of the illumination system 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.

2. The system of claim 1, wherein the imperfection is a groove.

3. The system of claim 1, wherein the imperfection is a dot.
