Abstract

A head-mounted display includes a first display portion, a second display portion, and a support portion. The first display portion is capable of presenting an image to an eye of a user. The second display portion is capable of presenting an image to the other eye of the user. The support portion has a band member and a first communication member. The band member connects the first display portion and the second display portion with each other and is curved to be disposed around a head portion of the user. The first communication member is disposed in the band member and electrically connects the first display portion and the second display portion.

Claims

1. A head-mounted display, comprising:

a first display portion capable of presenting an image to an eye of a user;

a second display portion capable of presenting an image to the other eye of the user; and

a support portion comprising a band member and a first communication member, the band member connecting the first display portion and the second display portion with each other and being curved to be disposed around a head portion of the user, the first communication member being disposed in the band member and communicatively connecting the first display portion and the second display portion.

2. The head-mounted display according to claim 1, wherein

the band member comprises a first molded body formed of a first synthetic resin material, and

the first communication member is insert-molded in the first molded body.

3. The head-mounted display according to claim 2, wherein

the band member further comprises a second molded body that is formed of a second synthetic resin material having a higher elasticity than the first synthetic resin material and covers at least an outer circumferential surface of the first molded body.

4. The head-mounted display according to claim 3, wherein

the second molded body comprises a plurality of columnar portions each having a height that reaches the first communication member from the outer circumferential surface of the first molded body.

5. The head-mounted display according to claim 1, wherein

the first communication member is disposed on an outer circumferential side from a neutral plane of the band member.

6. The head-mounted display according to claim 1, wherein

the support portion further comprises an ear-hook portion disposed on an inner circumferential surface of the band member.

7. The head-mounted display according to claim 6, wherein

the ear-hook portion is formed slideably in a circumferential direction of the band member.

8. The head-mounted display according to claim 6, wherein

the ear-hook portion comprises:

an attachment end portion attached to the band member, and

a belt-like portion attached to the attachment end portion and deformable in a radial direction of the band member.

9. The head-mounted display according to claim 1, further comprising:

a controller configured to control the first display portion and the second display portion, wherein

the support portion further comprises a second communication member that is disposed in the band member and communicatively connects the first display portion with the controller.

10. The head-mounted display according to claim 9, wherein

the second communication member is disposed on an inner circumferential side from the first communication member in the band member.

11. The head-mounted display according to claim 9, wherein

the band member has a bottom surface portion where a groove portion on which the second communication member is mounted is formed, and

the support portion further comprises a support body that supports the second communication member and is fixed to the bottom surface portion.

13. The head-mounted display according to claim 1, wherein the first communication member is a conductive member.

14. The head-mounted display according to claim 1, wherein the first communication member is an optical fiber.

15. The head-mounted display according to claim 1, wherein the first communication member is a conductive member that forms an electrical connection.

16. The head-mounted display according to claim 4, wherein the plurality of columnar portions are distributed periodically around the second molded body.

17. The head-mounted display according to claim 1, wherein

the support portion further comprises a second communication member being disposed in the band member.

18. The head-mounted display according to claim 17, wherein

the second communication member communicatively connects the first display portion to a controller.

19. The head-mounted display according to claim 18, further comprising:

a controller configured to output image signals, wherein

the second communication member communicatively connects the first display portion to the controller.

20. The head-mounted display according to claim 18, wherein the second communication member is disposed, at least in part, on an inner circumferential side from a neutral plane of the band member.

12. A head-mounted display, comprising:

a first display portion capable of presenting an image to an eye of a user;

a second display portion capable of presenting an image to the other eye of the user; and

a support portion comprising a band member and an ear-hook portion that is disposed on an inner circumferential surface of the band member, the band member connecting the first display portion and the second display portion with each other and being curved to be disposed around a head portion of the user.

21. A method of making a device, the method comprising:

disposing a first communication member in a first cavity formed from a first mold and a second mold; and

injecting a first synthetic resin into the first cavity to form a first molded body.

22. The method of making a device according to claim 21, wherein

disposing a first communication member in a first cavity comprises holding the first communication member by applying a vacuum to a plurality of hollow holding pieces that are in contact with the first communication member.

23. The method of making a device according to claim 22, wherein

an outer circumferential surface of the first molded body includes a plurality of holes formed by the placement of the plurality of hollow holding pieces during injection of the first synthetic resin.

24. The method of making a device according to claim 23, further comprising:

disposing the first molded body in a second cavity formed from a third mold and a fourth mold; and

injecting a second synthetic resin into the second cavity to form a second molded body such that the plurality of holes are filled with the second synthetic resin.

25. The method of making a device according to claim 24, further comprising:

disposing the first molded body in a second cavity formed from a third mold and a fourth mold.
