Abstract

Aspects of the present invention relate to methods and systems for a head-worn computer with a content display where the head-worn computer can be changed from an augmented reality system where there is relatively high see-through transmission through the display to a virtual reality system where the is no or relatively little see-through transmission through the display.

Claims

1. A stray light suppression system, comprising:

a shroud mechanically adapted to be removably and replacably mounted to a see-through display system adapted to be worn on the head of a user;

the shroud further adapted to, when mounted on the see-through display system, suppress light emitted from the see-through display system and suppress surrounding environment light from entering sides of the see-through display system

wherein the system further comprises a peripheral light effects system adapted to effect peripheral light effects in coordination with content presented in a field of view.

2. The system of claim 1, wherein the lighting effects are colored lighting effects.

3. The system of claim 1, wherein the peripheral lighting effects system-comprises a light source substantially surrounding the inside cavity for controlled placement of the effect lighting direction.

4. The system of claim 1, wherein the peripheral light effects system produces lighting effects with LEDs or OLEDs.

5. The system of claim 1, wherein the shroud has a dedicated power system.
