Abstract

The technology disclosed relates to providing devices and methods for attaching motion capture devices to head mounted displays (HMDs) using existing features of the HMDS, with no modification to the design of the HMDs. A motion capture device is attached with an adapter to a wearable device that can be a personal HMD having a goggle form factor. The motion capture device is operable to be attached to or detached from an adapter, and the adapter is operable to be attached to or detached from an HMD. The motion capture device is attached to the HMD with an adapter in a fixed position and orientation. In embodiments, the attachment mechanism coupling the adapter to the HMD utilizes existing functional or ornamental elements of an HMD. Functional or ornamental elements of the HMD include; air vents, bosses, grooves, recessed channels, slots formed where two parts connect, openings for head straps etc.

Claims

1. A device for attaching a motion capture device to a head mounted display comprising:

a main body portion including an opening that is configured to removably receive and hold the motion capture device;

a pair of opposing flanged ends on opposite sides of the main body portion; and

at least one retaining clip located on each flanged end configured to be received by detents on surfaces of the head mounted display.

2. The device of claim 1, wherein the detents are air vents on opposite sides of the head mounted display.

3. The device of claim 1, wherein the main body portion comprises a mounting flange configured to create a friction fit with the motion capture device.

4. The device of claim 3, wherein the mounting flange includes a channel that allows for insertion of a power or data cable into the motion capture device.

5. The device of claim 1, wherein the main body portion comprises at least one aperture configured to allow a radiation emitter on a surface of the head mounted display covered by the main body to emit radiation through the main body portion.

6. The device of claim 1, wherein the main body portion is configured to receive adapter plates that attach the motion capture device to the head mounted display.

7. The device of claim 1, wherein the detents are bosses on the head mounted display.

8. The device of claim 1, wherein the detents are grooves on the head mounted display.

9. The device of claim 1, wherein the detents are recessed channels on the head mounted display.

10. The device of claim 1, wherein the detents are slots formed where two parts of the head mounted display connect.

11. The device of claim 1, wherein the detents are openings for head straps of the head mounted display.

12. The device of claim 1, further including attaching the motion capture device to the head mounted display using adhesives.

13. The device of claim 1, further including attaching the motion capture device to the head mounted display using magnets.

14. The device of claim 1, wherein the main body portion is curved.

15. The device of claim 1, wherein the main body portion includes curved surfaces.

16. The device of claim 1, wherein the main body portion includes surface features configured to be complementary to surface features of a surface of the head mounted display.

17. A device for attaching a motion capture device to a head mounted display comprising:

a main body portion including an opening that is configured to removably receive and hold the motion capture device, wherein the main body portion is configured to receive adapter plates that attach the motion capture device to the head mounted display;

a pair of opposing flanged ends on opposite sides of the main body portion; and

at least one retaining clip located on each flanged end configured to be received by detents on surfaces of the head mounted display.

18. A device for attaching a motion capture device to a head mounted display comprising:

a main body portion including an opening that is configured to removably receive and hold the motion capture device;

a pair of opposing flanged ends on opposite sides of the main body portion and at least one retaining clip located on the main body portion; and

at least one adapter plate attached to the head mounted display and configured to receive the flanged ends and the retaining clip.
