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 system comprising:
one or more processors;
a light source;
a see-through display configured to present a view of an environment of a user of a wearable head device;
an eyeglasses frame coupled to the see-through display; and
an eye cover configured to removably couple to the eyeglasses frame, wherein:
the eye cover comprises a magnetic attachment element and an opening,
the eye cover is removable from the eyeglasses frame by disengaging the magnetic attachment element from the eyeglasses frame, and
the see-through display is configured to present the view of the environment via the opening of the eye cover,

wherein the wearable head device is configured to communicate with the one or more processors, wherein the one or more processors are configured to perform a method comprising:
determining whether the eye cover is physically coupled to the eyeglasses frame;
in accordance with a determination that the eye cover is physically coupled to the eyeglasses frame, presenting light, via the light source, to the user via the see-through display in a first display mode; and
in accordance with a determination that the eye cover is not physically coupled to the eyeglasses frame, presenting light, via the light source, to the user via the see-through display in a second display mode different from the first display mode.

2. The system of claim 1 , wherein the eye cover is further configured to contact the user of the wearable head device.

3. The system of claim 1 , wherein the eye cover is further configured to encapsulate an eye of the user of the wearable head device.

4. The system of claim 1 , wherein the first display mode comprises a low-light display mode.

5. The system of claim 1 , wherein the eye cover comprises a flexible material.

6. The system of claim 1 , wherein the eye cover comprises a bellows.

7. The system of claim 1 , further comprising a front lens and a light shield, wherein:
the light source is configured to transmit light toward an exterior of the wearable head device via the front lens, and
the light shield is configured to suppress the light transmitted toward the exterior of the wearable head device via the front lens.

8. The system of claim 7 , wherein the light transmitted toward the exterior of the wearable head device via the front lens has a first polarization, and the light shield is configured to suppress light having the first polarization.

9. The system of claim 1 , wherein the view of the environment comprises a night vision view of the environment.

10. The system of claim 1 , wherein the light is presented to the user via the see-through display in the first display mode further in accordance with a determination that a light level of the environment is below a threshold light level.

11. The system of claim 1 , wherein the presenting the light in the first display mode comprises presenting monochrome light.

12. The system of claim 1 , wherein the presenting the light in the second display mode comprises presenting color light.

13. A method comprising:
determining whether an eye cover of a wearable head device comprising a light source and a see-through display is physically coupled to an eyeglasses frame of the wearable head device, wherein the see-through display is configured to present a view of an environment of a user of the wearable head device;
in accordance with a determination that the eye cover is physically coupled to the eyeglasses frame, presenting light, via the light source, to the user via the see-through display in a first display mode; and
in accordance with a determination that the eye cover is not physically coupled to the eyeglasses frame, presenting light, via the light source, to the user via the see-through display in a second display mode different from the first display mode, wherein:
the eyeglasses frame is coupled to the see-through display,
the eye cover is configured to removably couple to the eyeglasses frame,
the eye cover comprises a magnetic attachment element and an opening,
the eye cover is removable from the eyeglasses frame by disengaging the magnetic attachment element from the eyeglasses frame, and
the see-through display is configured to present the view of the environment via the opening of the eye cover.

14. The method of claim 13 , wherein the eye cover is further configured to contact the user of the wearable head device.

15. The method of claim 13 , wherein the first display mode comprises a low-light display mode.

16. The method of claim 13 , wherein the eye cover comprises a flexible material.

17. The method of claim 13 , wherein the view of the environment comprises a night vision view of the environment.

18. The method of claim 13 , wherein the light is presented to the user via the see-through display in the first display mode further in accordance with a determination that a light level of the environment is below a threshold light level.

19. The method of claim 13 , wherein the presenting the light in the first display mode comprises presenting monochrome light.

20. The method of claim 13 , wherein the presenting the light in the second display mode comprises presenting color light.
