Abstract

Aspects of the present disclosure relate to head worn computing lighting systems and stray light control.

Claims

1. A computer display stray-light suppression system for a head-worn computer, comprising:

a. An eye cover including an elastic material with a perimeter, wherein the perimeter is formed to substantially encapsulate an eye of a person; and

b. The eye cover including a magnetic 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.

2. The computer display stray-light suppression system for a head-worn computer of claim 1, wherein the magnetic attachment system includes a magnet of a first polarization attached to the eye cover and a magnet of a second polarization attached to the head-worn computer.

3. The computer display stray-light suppression system for a head-worn computer of claim 1, wherein the magnetic attachment system includes a magnet attached to the eye cover.

4. The computer display stray-light suppression system for a head-worn computer of claim 1, wherein the magnetic attachment system includes a magnet attached to the head-worn computer.

5. The computer display stray-light suppression system for a head-worn computer of claim 1, wherein the eye cover is adapted to cover one eye of the person.

6. The computer display stray-light suppression system for a head-worn computer of claim 1, wherein the eye cover is adapted to cover both eyes of the person.

7. The computer display stray-light suppression system for a head-worn computer of claim 1, further comprising a processor in the head-worn computer adapted to detect when the eye cover is attached to the head-worn computer.

8. The computer display stray-light suppression system for a head-worn computer of claim 7, wherein the processor changes a lighting condition of the head-worn computer when the eye cover is attached to the head-worn computer.

9. The computer display stray-light suppression system for a head-worn computer of claim 1, further comprising a front cover adapted to cover a front lens of the head-worn computer to suppress stray light from escaping the front lens.

10. The computer display stray-light suppression system for a head-worn computer of claim 9, wherein the front cover substantially covers one front lens of the head-worn computer.
