Abstract

A strap system and a method for wearing the strap system are disclosed. The strap system includes a first flexible segment comprising a first stretchable band; a first semi-rigid segment to conform to a portion of the user's head and comprising a first arc portion to extend from above a user's first ear to below the user's occipital lobe; and a first rigid guide segment connected to the first flexible segment and the first semi-rigid segment. The first flexible segment extends beyond a first end of the first rigid guide segment and the first semi-rigid segment extends from a second end of the first rigid guide segment, the first and second ends of the first rigid guide segment being opposite to each other in a lateral dimension. The first flexible segment is stretchable within the first rigid guide segment along the lateral dimension.

First claim

What is claimed is:

1. A strap system for mounting a head-mounted display on a user's head, comprising:
a first flexible segment comprising a first stretchable band;
a first semi-rigid segment to conform to a portion of the user's head, comprising a first arc portion to extend from above a user's first ear to below the user's occipital lobe; and
a first rigid guide segment connected to the first flexible segment and the first semi-rigid segment, wherein:
the first flexible segment extends beyond a first end of the first rigid guide segment and the first semi-rigid segment extends from a second end of the first rigid guide segment, the first and second ends of the first rigid guide segment being opposite to each other in a lateral dimension, and
the first flexible segment is stretchable within the first rigid guide segment along the lateral dimension so as to adjust the strap system in accordance with the user's head.

2. The strap system of claim 1 , further comprising:
a rigid piece, coupled to the first semi-rigid segment, to rest against the back of the user's head.

3. The strap system of claim 2 , further comprising:
a second flexible segment comprising a second stretchable band; and
a second rigid guide segment connected to the second flexible segment, wherein:
the second flexible segment extends beyond a first end of the second rigid guide segment, and
the second flexible segment is stretchable within the second rigid segment along the lateral dimension so as to adjust the strap system in combination with the first flexible segment to fit the head-mounted display on the user's head.

4. The strap system of claim 3 , wherein:
the first semi-rigid segment further comprises a second arc portion to extend from above the user's second ear to below the user's occipital lobe,
the second rigid guide segment is connected to the first semi-rigid segment, and
a first end of the first semi-rigid segment extends from the second end of the first rigid guide segment, and a second end of the first semi-rigid segment extends from a second end of the second rigid guide segment, the first and second ends of the second rigid guide segment being opposite to each other in the lateral dimension.

5. The strap system of claim 3 , wherein:
the second rigid guide segment is connected to the first semi-rigid segment; and
the first semi-rigid segment passes through grooves in the rigid piece.

6. The strap system of claim 3 , further comprising a second semi-rigid segment comprising a second arc portion to extend from above a user's second ear to below the user's occipital lobe, the second semi-rigid segment being connected to the second rigid guide segment, wherein:
the first semi-rigid segment extends from the second end of the first rigid guide segment to the rigid piece, and
the second semi-rigid segment extends from a second end of the second rigid guide segment to the rigid piece, the first and second ends of the second rigid guide segment being opposite to each other in the lateral dimension.

7. The strap system of claim 2 , further comprising a top strap having a first end connected to the rigid piece and a second end to adjustably fit the head-mounted display on the user's head, the top strap to conform to the top of the user's head from the rigid piece to the head-mounted display.

8. The strap system of claim 2 , further comprising a plurality of Infrared (IR) LED lights coupled to the rigid piece for tracking motions of the user's head.

9. The strap system of claim 8 , further comprising flat flexible circuits attached to the first semi-rigid segment and the rigid piece to provide power to the plurality of IR LED lights.

10. The strap system of claim 1 , wherein:
the first flexible segment further comprises a first flexible non-stretchable band connected to the first stretchable band;
a first end of the first stretchable band is connected to the first rigid guide segment, and
the first flexible non-stretchable band has a first end connected to a second end of the first stretchable band, and a free second end to slide through the head-mounted display to adjustably fit the head-mounted display on the user's head.

11. The strap system of claim 10 , wherein the first flexible non-stretchable band of the first flexible segment comprises bendable, non-elastic material.

12. The strap system of claim 1 , further comprising a mounting device connected to the first rigid guide segment and connectable to the head-mounted display,
wherein the mounting device includes a rotation pivot point, the mounting device being rotatable relative to the rotation pivot point so as to provide rotation of the first rigid guide segment with respect to the head-mounted display.

13. The strap system of claim 1 , wherein the first stretchable band of the first flexible segment comprises an elastic material.

14. The strap system of claim 1 , wherein the first semi-rigid segment comprises a semi-rigid plastic material.

15. The strap system of claim 1 , wherein:
the first rigid guide segment comprises rigid plastic material, and
the first rigid guide segment includes a channel within which to stretch the first stretchable band of the first flexible segment along the lateral dimension.
