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, wherein the optical assembly comprises a partially reflective, partially transmitting optical element that reflects a portion of image light from the image source and transmits scene light from a see-through view of the surrounding environment, so that a combined image comprised of portions of the reflected image light and the transmitted scene light is provided to a user'"'"'s eye.

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 and 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,

wherein the optical assembly comprises a partially reflective, partially transmitting optical element that reflects a portion of image light from the image source and transmits scene light from a see-through view of the surrounding environment, so that a combined image comprised of portions of the reflected image light and the transmitted scene light is provided to a user'"'"'s eye.

2. The system of claim 1, wherein the partially reflective, partially transmitting optical element is an optically flat film, disposed at an angle in front of a user'"'"'s eye.

3. The system of claim 1, wherein the partially reflective, partially transmitting optical element is a curved partially reflecting mirror.

4. The system of claim 1, wherein the integrated image source comprises a light source that directs light to a curved polarizing film of the optical assembly that reflects a portion of the light to illuminate a reflective image display of the optical assembly that reflects the illuminating light to provide image light.

5. The system of claim 1, wherein the image source comprises an auto-brightness control that controls the brightness of the displayed content based on the brightness in the environment.
