Abstract

Aspects of the present disclosure relate to a computer display stray-light suppression system for a head-worn computer comprising an eye cover including a flexible material with a perimeter, wherein the perimeter is formed to substantially encapsulate an eye of a person, and the eye cover including an attachment system adapted to removably and replaceably attach to a perimeter of the head-worn computer to suppress light emitted from a computer display in the head-worn computer.

First claim

We claim:

1. A light suppression system for a wearable head device, the stray light suppression system comprising: an eye cover comprising a flexible material, the eye cover having a perimeter, wherein:
the perimeter is formed to substantially encapsulate an eye of a user of the wearable head device; and
the eye cover further comprises an attachment system adapted to removably and replaceably attach to a perimeter of the wearable head device, wherein the eye cover is configured to suppress light emitted from a computer display of the wearable head device.

2. The light suppression system of claim 1 , wherein the attachment system comprises a magnetic attachment system.

3. The light suppression system of claim 2 , wherein the magnetic attachment system comprises a magnet of a first polarization attached to the eye cover and a magnet of a second polarization attached to the wearable head device.

4. The light suppression system of claim 2 , wherein the magnetic attachment system comprises a magnet attached to the eye cover.

5. The light suppression system of claim 2 , wherein the magnetic attachment system comprises a magnet attached to the wearable head device.

6. The light suppression system of claim 1 , wherein the eye cover is adapted to cover one eye of the user.

7. The light suppression system of claim 1 , wherein the eye cover is adapted to cover both eyes of the user.

8. The light suppression system of claim 1 , further comprising a processor adapted to detect when the eye cover is attached to the wearable head device.

9. The light suppression system of claim 8 , wherein the processor is configured to change a lighting condition of the wearable head device when the eye cover is attached to the wearable head device.

10. The light suppression system of claim 1 , further comprising a front cover adapted to cover a front lens of the wearable head device and further adapted to suppress stray light from escaping the front lens.

11. The light suppression system of claim 10 , wherein the front cover substantially covers one front lens of the wearable head device.
