Abstract

Methods and apparatus, including computer program products, implementing and using techniques for projecting a source image in a head-mounted display apparatus for a user. A first display projects an image viewable by a first eye of the user. A first peripheral light element is positioned to emit light of one or more colors in close proximity to the periphery of the first display. A receives data representing a source image, processes the data representing the source image to generate a first image for the first display and to generate a first set of peripheral conditioning signals for the first peripheral light element, directs the first image to the first display, and directs the first set of peripheral conditioning signals to the first peripheral light element. As a result, an enhanced viewing experience is created for the user.

Claims

1. A head-mounted display apparatus for a user, comprising:

a first display operable to project a first image viewable only by a first eye of the user;

a first peripheral light element positioned to emit light of one or more colors in close proximity to the periphery of the first display;

a second display operable to project a second image viewable only by a second eye of the user independent of the first image viewed by the first eye of the user;

a second peripheral light element positioned to emit light of one or more colors in close proximity to the periphery of the second display; and

a processor operable to;

receive data representing a source image;

divide the source image into a left image and a right image;

determine periphery colors for the left image and periphery colors for the right image;

combine the left image and the determined periphery colors for the left image by directing the first peripheral light element to display the determined left image periphery colors only in a peripheral region of the first image;

combine the right image and the determined periphery colors for the right image by directing the second peripheral light element to display the determined right image periphery colors only in a peripheral region of the second image; and

project the combined left image only to the first display and the combined right image only to the second display to create an enhanced viewing experience for the user.

2. The head-mounted display apparatus of claim 1, wherein the processor is operable to receive data representing the source image from an external source.

3. The head-mounted display apparatus of claim 2, wherein the external source is a portable source and includes a memory in which the source image is stored.

4. The head-mounted display apparatus of claim 1, further comprising:

a memory in which the data representing the source image is stored, the memory being operatively coupled to the processor.

5. The head-mounted display apparatus of claim 1, wherein the first display has an aspect ratio of 16/9.

6. The head-mounted display apparatus of claim 1, wherein the data representing the source image and the first image are image frames of a movie.

7. The head-mounted display apparatus of claim 1, wherein the first set of peripheral conditioning signals includes instructions for which one or more colors to display with the first peripheral light element.

8. The head-mounted display apparatus of claim 7, wherein the first set of peripheral conditioning signals includes instructions for how long to display the one or more colors.

9. The head-mounted display apparatus of claim 1, wherein the first image includes one or more colors, and the first set of peripheral conditioning signals includes instructions to display colors corresponding to at least some of the colors in the first image.

10. The head-mounted display apparatus of claim 9, wherein the processor is operable to:

divide the first image into a plurality of regions;

determine a dominating color for each region; and

include the dominating colors in the first set of peripheral conditioning signals.

11. The head-mounted display apparatus of claim 1, wherein the peripheral light elements are selected from the group consisting of:

light emitting diodes, electro luminescent displays and organic light emitting diodes.

12. The head-mounted display apparatus of claim 1, wherein the peripheral light elements are located at a distance from the first display and the light from the peripheral light elements are conveyed to the periphery of the display by optical fibers or light pipes.

13. The head-mounted display apparatus of claim 1, further comprising:

a user interface including one or more controls for providing instructions from the user to the processor about how to generate the first set of peripheral conditioning signals.

14. The head-mounted display apparatus of claim 1, further comprising a diffuser located in the light path between the first peripheral light element and the first eye of the user, the diffuser being operable to soften the light emitted by the first peripheral light element before the light reaches the first eye of the user.

15. The head-mounted display apparatus of claim 1, wherein the first and second images are horizontally translated relative to each other.

16. The head-mounted display apparatus of claim 1, wherein the first and second images are the same.

17. A computer-implemented method for projecting a source image in a head-mounted display apparatus for a user, the head-mounted display apparatus having a first display operable to project a first image viewable by a first eye of the user and a first peripheral light element positioned to emit light of one or more colors in close proximity to the periphery of the first display and, the method comprising:

receiving data representing a source image;

dividing the source image into a left image and a right image;

determining periphery colors for the left image and periphery colors for the right image;

combining the left image and the determined periphery colors for the left image by directing the first peripheral light element to display the determined left image periphery colors only in a peripheral region of the first image;

combining the right image and the determined periphery colors for the right image by directing the second peripheral light element to display the determined right image periphery colors only in a peripheral region of the second image; and

projecting the combined left image only to the first display and the combined right image only to the second display to create an enhanced viewing experience for the user.

18. The method of claim 17, wherein the data representing the source image is stored in a memory in the head-mounted display apparatus, the memory being operatively coupled to the processor.

19. The method of claim 17, wherein the first display has an aspect ratio of 16/9.

20. The method of claim 17, wherein the first set of peripheral conditioning signals includes instructions for which one or more colors to display with the first peripheral light element.

21. The method of claim 20, wherein the first set of peripheral conditioning signals includes instructions for how long to display the one or more colors.

22. The method of claim 17, wherein the first image includes one or more colors, and the first set of peripheral conditioning signals includes instructions to display colors corresponding to at least some of the colors in the first image.

23. The method of claim 17, wherein processing includes:

dividing the first image into a plurality of regions;

determining a dominating color for each region; and

including at least one of the dominating colors in the first set of peripheral conditioning signals.

24. The method of claim 17, wherein the peripheral light elements are selected from the group consisting of:

light emitting diodes, electro luminescent displays and organic light emitting diodes.

25. The method of claim 17, further comprising:

diffusing the light emitted by the first peripheral light element before the light reaches the first eye of the user.
