CLAIMS

What is claimed is:

1. A head-mounted display to be worn by a user, comprising:

a housing;

a component chamber defined in the housing;

electronic components that generate heat, wherein the electronic components are located in the component chamber of the housing; and

a first fan for causing air to flow through the component chamber.

2. The head-mounted display of claim 1, wherein the first fan directs air out of an upper part of the component chamber.

3. The head-mounted display of any of claims 1-2, further comprising:

a second fan that directs air into a lower part of the component chamber.

4. The head-mounted display of any of claims 1-3, further comprising:

an eye chamber defined in the housing; and

a first vent that allows air to pass from the eye chamber into the component chamber.

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

a second vent that allows air to enter the eye chamber from outside of the housing.

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

a second fan that directs air into the component chamber.

7. The head-mounted display of any of claims 1-6, further comprising:

a flow control component that can be moved between first and second positions to vary air flow through the housing.

8. The head-mounted display of any of claims 1 or 7, wherein operation of the first fan is controlled based on a temperature of the electronic components.

9. The head-mounted display of any of claims 1 or 7, wherein operation of the first fan is controlled based on an air temperature in the component chamber.

10. The head-mounted display of any of claims 1 or 7, further comprising:

an eye chamber defined in the housing, wherein operation of the first fan is controlled based on an air temperature in the eye chamber.

11. The head-mounted display of any of claims 1 or 7, further comprising:

an eye chamber defined in the housing, wherein operation of the first fan is controlled based on humidity in the eye chamber.

12. The head-mounted display of any of claims 1 or 7, wherein operation of the first fan is controlled based on a skin temperature of the user.

13. The head-mounted display of any of claims 1 or 7, wherein operation of the first fan is controlled based on perspiration by the user.

14. The head-mounted display of any of claims 1-13, further comprising:

a headband that is connected to the housing and configured to support the housing relative to the user;

display devices that are operable to display content output by the electronic components;

an eye chamber defined by the housing; and

a face seal that extends around the eye chamber.

15. A head-mounted display to be worn by a user, comprising:

a housing;

an eye chamber defined by the housing;

a face seal; and

a fan that causes air to flow through the face seal.

16. The head-mounted display of claim 15, wherein the face seal includes an interior portion that conducts air flow along the length of the face seal and a cover portion.

17. The head-mounted display of claim 16, wherein the interior portion of the face seal is an air-permeable material and the cover portion is an air-impermeable material.

18. The head-mounted display of any of claims 15-17, wherein openings extend through the cover portion to allow air to flow out of the face seal.

19. A head-mounted display to be worn by a user, comprising:

a housing;

an eye chamber defined by the housing;

a display;

electronic components that cause content to be output by the display; and

a fan that causes air to flow through the eye chamber, wherein the fan is controlled by the electronic components based on the content.

20. The head-mounted display of claim 19, wherein the fan is controlled to vary an air flow speed based on the content and the fan is controlled to vary an air flow direction based on the content.
