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 photochromic layer and a heater layer disposed on a see-through lens of the optical assembly, wherein the photochromic layer is heated by the heater layer to accelerate its transition from dark to clear.

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,

wherein the optical assembly comprises a photochromic layer and a heater layer disposed on a see-through lens of the optical assembly,

wherein the photochromic layer is heated by the heater layer to accelerate its transition from dark to clear.

2. The system of claim 1, further comprising a camera to capture at least one of a hand gesture, a body movement, and an external cue that is processed by the processor to provide a command to the heater layer.

3. The system of claim 1, further comprising an accelerometer to capture a head movement that is processed by the processor to provide a command to the heater layer.

4. The system of claim 1, further comprising a microphone to capture audio that is processed by the processor to provide a command to the heater layer.

5. The system of claim 1, further comprising an ambient light sensor to capture an ambient light level that is processed by the processor to provide a command to the heater layer.
