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. An apparatus, comprising:

a. a platform mechanically adapted to be worn on a head of a user;

b. a see-through image display mounted on the platform and adapted to present image content to an eye of the user, wherein the see-through image display also provides the user a see-through view of an environment proximate the user;

c. a removable and replaceable eye cover adapted to connect to the platform, wherein the eye cover is further adapted to contain light from escaping an internal cavity formed at a facial interface with the user; and

d. a removable and replaceable outer lens mounted on the platform along an optical axis in-line with the user'"'"'s see-through view of the environment.

2. The apparatus of claim 1, wherein the eye cover is adapted to connect to the platform with a magnet.

3. The apparatus of claim 1, wherein the eye cover is adapted to connect to the platform with a mechanical attachment.

4. The apparatus of claim 1, wherein the eye cover is adapted to connect to the platform at least in part by being held in place by arms attached to the platform, where in the arms are adapted to hold the platform on the user'"'"'s head.

5. The apparatus of claim 1, wherein the outer lens has a see-through transparency of between 2% and 5% to create an immersive environment for the user while creating a transparency that maintains a visual connection for the user to the surrounding environment.

6. The apparatus of claim 1, wherein the outer lens has a see-through transparency of between 5% and 10% to create an immersive environment for the user while creating a transparency that maintains a visual connection for the user to the surrounding environment.

7. The apparatus of claim 1, wherein the outer lens has a see-through transparency of between 10% and 20% to create an immersive environment for the user while creating a transparency that maintains a visual connection for the user to the surrounding environment.

8. The apparatus of claim 1, wherein the outer lens has a see-through transparency of greater than 20%.

9. The apparatus of claim 1, wherein the outer lens as an electronically adjustable transparency.

10. The apparatus of claim 9 wherein the electronically adjustable transparency is based on a liquid crystal system.

11. The apparatus of claim 1, wherein the outer lens has a low transparency in an area behind a field of view presented to the eye of the user and a higher transparency outside of the area behind the field of view.

12. The apparatus of claim 1, wherein the outer lens has mechanically adjustable cross polarizers for adjustment of the see-through transparency.

13. The apparatus of claim 1, wherein the eye cover has an area of transparency to provide the user with a perspective of the surrounding environment.

14. The apparatus of claim 13, wherein the transparency is a partial transparency.

15. The apparatus of claim 1 wherein the eye cover further comprises an internal lighting effects system to provide peripheral lighting effects in coordination with content presented in a field of view.

16. The apparatus of claim 15, wherein the internal light effects system produces lighting effects with LEDs or OLEDs.

17. The apparatus of claim 16, wherein the lighting effects are colored lighting effects.

18. The apparatus of claim 15, wherein the internal lighting system includes a light source substantially surrounding the inside cavity for controlled placement of the effect lighting direction.

19. The apparatus of claim 1, wherein the eye cover further includes a tactile effects system adapted to effect tactile effects in coordination with content presented in a field of view.

20. The apparatus of claim 19, wherein the tactile effects system includes a piezo vibratory system

21. The apparatus of claim 20 where in the piezo vibratory system is positioned on a side of the eye cover.

22. The apparatus of claim 20 where in the piezo vibratory system is positioned on top of the eye cover.

23. The apparatus of claim 20 where in the piezo vibratory system is positioned on bottom of the eye cover.

24. The apparatus of claim 1, further comprising a data connection between the eye cover and the platform.

25. The apparatus of claim 24, wherein the data connection is established through an attachment system that mechanically connects the eye cover to the platform.

26. The apparatus of claim 24, wherein the data connection is a wireless data connection.
