Head-mounted face image capturing devices and systems

1. A head-mounted device comprising:

a) a head-mounted frame component configured to be mounted on the head of a user; and

b) an extending component connected at a first end to said head-mounted frame component and connected to a single camera at or near a second end opposite to said first end, wherein said extending component is moveable between:

a first position in or adjacent to said head-mounted frame component, wherein said first position allows said single camera to capture images of what said user is seeing, and

a second position non-adjacent to said head-mounted frame component, wherein said second position allows said single camera to capture an image not viewable by said user.

2. The device of claim 1 , wherein the second position allows said camera to capture a rear-view image.

3. The device of claim 2 , wherein the extendable component extends from said head-mounted frame component to adopt said second position.

4. The device of claim 3 , wherein the extendable component is extended 0.5-6 inches from the head-mounted frame component to the side of a user wearing said device to adopt said second position.

5. The device of claim 1 , wherein said extending component further comprises a telescoping internal rod that is configured to extend from within said extendable component.

6. The device of claim 1 , wherein extending component is further moveable into a third position that allows said camera to capture an image of said user's face.

7. The device of claim 6 , wherein said extending component is hingedly connected to said head-mounted frame component.

8. The device of claim 7 , wherein the extendable component pivots from said head-mounted frame component to adopt said second position that allows said camera to capture a rear-view image.

9. The device of claim 7 , wherein the extending component pivots from said head-mounted frame component to adopt said third position.

10. The device of claim 1 , wherein the camera resides within a housing and the housing is movable with respect to the extending component via a housing component hinge.

11. The device of claim 10 , wherein said extending component comprises a camera casing recess configured to allow said housing component and camera to pivot therein via said housing component hinge.

12. The device of claim 1 , further comprising at least one lens, wherein said at least one lens is attached to said head-mounted frame component, and is configured to at least partially cover said user's eye when said device is mounted on said user's head.

13. The device of claim 12 , further comprising a projection device configured to project an image onto or into said at least one lens such that it can be seen by said user.

14. The device of claim 13 , wherein said extending component is in said second position and said image is a rear-view image captured by said camera.

15. The device of claim 14 , wherein said rear-view image is a real-time video.

16. The device of claim 1 , further comprising at least one screen, wherein said at least one screen is attached to said head-mounted frame component, and is configured to be viewable by said user when said device is mounted on said user's head.

17. The device of claim 1 , further comprising a communication element, wherein said communication element is configured to wirelessly (i) transmit images or other data and/or (ii) receive data from an outside source.

18. The device of claim 15 , wherein said communication element is configured to transmit and receive data to/from said user's cellular phone or other device.

19. The device of claim 15 , wherein said communication element is configured to transmit and receive data to/from a cellular, 3G, 4G, or other network.

20. The device of claim 1 , further comprising a microphone.
