Abstract

AN HMD is disclosed including a pair of temple arms which wrap around a portion of a user'"'"'s head. The temple arms provide long axis (front to back) compression, and compression against sides of the user'"'"'s head. Such a distribution of forces prevents resting of the HMD primarily on the nose, ears or the top of the head, and allows the HMD to be worn in a way that is comfortable and non-intrusive.

Claims

1. A temple arm for a head mounted display, the temple arm including a first end proximal optics for the head mounted display and a second end opposite the first end, the arm comprising:

a band extending at least partially between the first and second ends;

a spring extending at least partially between the first and second ends, the spring and band affixed together at the first and second ends and the spring being longer than the band and flexed away from the band in one of a first direction and a second direction, the band being substantially straight when the spring is flexed into the first direction, and the band bending when the spring is flexed into the second direction.

2. The temple arm of claim 1, the band comprising a first band, the temple arm further comprising a second band affixed to the first band and the spring at the first and second ends of the temple arm, the second band being substantially straight when the spring is flexed into the first direction, and the band bending when the spring is flexed into the second direction.

3. The temple arm of claim 2, wherein the first and second bands are coplanar when the spring is flexed in the first direction, and bent in the same way when the spring is in the second direction.

4. The temple arm of claim 1, wherein the spring is configured to flex from the first direction to the second direction by a force exerted on the spring by a head of a wearer upon the wearer putting on the head mounted display.

5. The temple arm of claim 4, wherein the distal end of the temple arm wraps around a portion of the wearer'"'"'s head when the band bends upon the spring flexing to the second direction.

6. The temple arm of claim 5, wherein a portion of the band that flexes is positioned adjacent the first end of the temple arm so that the spring does not engage the wearer'"'"'s end until the band is in position to wrap around the portion of the wearer'"'"'s head.

7. The temple arm of claim 1, further comprising an interface material extending at least partially between the first and second ends, and at least partially encasing the band and spring, the interface material provided for comfort.

8. The temple arm of claim 1, wherein the optics of the head mounted display are capable of displaying virtual images to the optics to create a virtual or augmented reality environment.

9. A temple arm for a head mounted display, the temple arm including a first end proximal optics for the head mounted display and a second end opposite the first end, the arm comprising:

a plurality of arm sections; and

a plurality of spring joints between and affixing the arm sections, a spring joint including a spring and one or more fasteners for affixing the spring joint between adjacent arm sections of the plurality of arm sections, the spring biasing the adjacent arm sections to fold toward each other, the adjacent arm sections including ends which come together to limit folding of the adjacent arm sections with respect to each other.

10. The temple arm of claim 9, wherein folding of adjacent arm sections in the plurality of arm sections under bias of the springs of the plurality of spring joints wraps the temple arm at least partially around a head of a wearer to support the head mounted display on the head of the wearer.

11. The temple arm of claim 10, wherein forces exerted by different arm sections on different portions of the head of the wearer are controlled by controlling spring constants of the plurality of springs of the spring joints.

12. The temple arm of claim 11, wherein a spring constant for a spring adjacent the second end of the temple arm is larger than a spring constant for a spring positioned closer to the first end of the temple arm.

13. The temple arm of claim 9, wherein the plurality of arm sections comprise at least four arm sections and the plurality of spring joints comprise at least three spring joints.

14. The temple arm of claim 9, wherein at least one of the arm sections has an adjustable length.

15. The temple arm of claim 9, wherein the optics of the head mounted display are capable of displaying virtual images to the optics to create a virtual or augmented reality environment.

16. A method of supporting a head mounted display on a head of a wearer, the head mounted display including optics, the method comprising:

(a) configuring a pair of temple arms affixed to the optics to maintain a first shape enabling the temple arms to be positioned on opposite temples of a wearer;

(b) configuring the pair of temple arms to maintain a second shape where each temple arm includes at least a portion distal from the optics that wrap partially around a head of the wearer; and

(c) providing a mechanism for moving the pair of temple arms from the first shape to the second shape when the head mounted display is worn by the user.

17. The method of claim 16, said step (c) comprising the steps of:

providing first and second layers to each of the temple arms, the first and second layers affixed to each other, and

changing a length of the first layer with respect to the second layer.

18. The method of claim 17, said step of changing a length of the first layer with respect to the second layer comprising the steps of threading a cord through the first layer and shortening a length of the cord.

19. The method of claim 16, said step (c) comprising the step of providing each temple arm with a band and a spring affixed to each other at opposed ends, the spring being longer than the band and flexed away from the band in one of a first direction and a second direction, the band being substantially straight when the spring is flexed into the first direction, and the band bending when the spring is flexed into the second direction.

20. The method of claim 16, said step (c) comprising the step of providing each temple arm with a plurality of arm sections, and a plurality of spring joints between and affixing the arm sections, a spring joint including a spring and one or more fasteners for affixing the spring joint between adjacent arm sections of the plurality of arm sections, the spring biasing the adjacent arm sections to fold toward each other, the wearer holding the arm sections in the first shape and the spring joints moving the arm sections to the second shape around the wearer'"'"'s head when the wearer releases the arm sections.
