Abstract

A head mounted display is provided. The head mounted display includes an optics block having a display screen. The optics block has a forward-facing region, a lower-facing region, a top-facing region, an inside-facing region, and side regions that extend from the forward-facing region toward the inside-facing region. The display screen is viewable from the inside-facing region. A band adjustment unit is located opposite the optics block. A headband has a front portion and an adjustable portion. The adjustable portion of the headband is connected to the band adjustment unit to contract a size of the headband or expand the size of the headband. The front portion of the headband has a connection to the top-facing region of the optics block that is proximate to the inside-facing region. A pad is disposed inside of the front portion of the headband. The pad provides for at least partial support of the optics block when the head mounted display is worn by a user.

Claims

1. A head mounted display, comprising:

an optics block includes a display screen, the optics block having a forward-facing region, a lower-facing region, a top-facing region, an inside-facing region, and side regions that extend from the forward-facing region toward the inside-facing region, the display screen being viewable from the inside-facing region;

a band adjustment unit located opposite the optics block;

a headband having a front portion and an adjustable portion,

the adjustable portion of the headband is connected to the band adjustment unit to contract a size of the headband or expand the size of the headband;

the front portion of the headband having a connection to the top-facing region of the optics block that is proximate to the inside-facing region; and

a pad disposed inside of the front portion of the headband, the pad provides for at least partial support of the optics block when the head mounted display is worn by a user.

2. The head mounted display of claim 1, wherein the band adjustment unit includes a rotary wheel that turns to contract the size or expend the size of the headband.

3. The head mounted display of claim 2, wherein to contract the size of the headband a portion of the headband moves into the band adjustment unit and to expand the size of the headband a portion of the headband moves out of the band adjustment unit.

4. The head mounted display of claim 1, wherein the connection of the front portion of the headband extends and curves from a lower region of the front portion of the headband to secure the headband to the top-facing region of the optics block.

5. The head mounted display of claim 4, wherein the connection is disposed substantially to a center location of the top-facing region of the optics block.

6. The head mounted display of claim 1, wherein the pad has a curved structure, the curved structure providing an inner pad surface for contact with an upper-front-region of a head of the user.

7. The head mounted display of claim 6, wherein the curved structure of the pad has a partial radial surface that partially extends above the front portion of the headband.

8. The head mounted display of claim 1, wherein the adjustable portion of the headband is curved and includes a padded inner surface that faces the pad that is coupled to the inside surface of the front portion of the headband.

9. The head mounted display of claim 6, wherein the upper-front-region of the head of the user is disposed above eyes of the user and includes at least part of an upper forehead of the user.

10. The head mounted display of claim 1, wherein the adjustable portion of the headband is disposed in the band adjustment unit, the band adjustment unit having a curved inner surface to be disposed proximate to a lower rear portion of a head of the user.

11. The head mounted display of claim 1,

wherein the pad has a curved structure, the curved structure providing an inner pad surface for contact with an upper-front-region of a head of the user and the curved structure of the pad extends above the front portion of the headband;

wherein the adjustable portion of the headband is disposed in the band adjustment unit, the band adjustment unit having a curved padded inner surface to be disposed proximate to a lower rear portion of the head of the user.

12. The head mounted display of claim 1, wherein the pad has a curved structure, the curved structure providing an inner pad surface for contact with an upper-front-region of a head of the user, the front portion of the headband being wider than sides of the headband.

13. The head mounted display of claim 1, wherein the pad has a curved structure, the curved structure providing an inner pad surface for contact with an upper-front-region of a head of the user, the front portion of the headband with the pad being wider than sides of the headband.

14. The head mounted display of claim 13, wherein the adjustable portion of the headband is disposed in the band adjustment unit, the band adjustment unit having a partially curved padded inner surface to be disposed proximate to a lower rear portion of the head of the user when worn.

15. The head mounted display of claim 14, wherein the band adjustment unit includes a rotary wheel that turns to contract the size or expend the size of the headband.

16. The head mounted display of claim 1, wherein the band adjustment unit includes one or more of a wheel adjuster, or a belt adjuster, or a notched adjuster, or a pin and hole adjuster, or a snap adjuster, or a Velcro adjuster, or a tape adjuster, or a belt and buckle adjuster, or a rope adjuster, or a link connector adjuster, or an elastic adjuster, or a clip adjuster, or a lock adjuster, or a combination of two or more thereof.

17. The head mounted display of claim 1, wherein the inside-facing region is configured to be disposed in front of eyes of the user when the head mounted display is worn.

18. The head mounted display of claim 1, wherein the forward-facing region is integral with and curves into the side regions of the optics block.

19. The head mounted display of claim 1, wherein the forward-facing region includes one or more cameras.

20. The head mounted display of claim 1, wherein two or more forward-facing cameras are disposed in the forward-facing region.

21. The head mounted display of claim 1, further comprising, an inertial sensor integrated in the optics block for tracking movement of the head mounted display when used by the user.

22. The head mounted display of claim 1, wherein the headband is wider at the front portion and less wide along sides of the headband where the headband connects to the band adjustment unit, and the connector has a curve extending a lower front section of the front portion of the headband, the curve of the connector joining to the top-facing region of the optics block for supporting the optics block with said headband and band adjustment unit.
