Abstract

A headset can include a frame; a display assembly supported by the frame; a motion sensor that generates motion data responsive to motion of the frame; and circuitry that generates a frame fit signal via the motion data.

First claim

What is claimed is:

1. A headset comprising:
a frame;
a display assembly supported by the frame;
a motion sensor that generates motion data responsive to motion of the frame; and
circuitry that generates a frame fit signal via the motion data, wherein the circuitry analyzes the motion data for a rebound of the frame after a maximum excursion of the frame and analyzes the motion data using a geometric model for the rebound to determine a metric to characterize looseness of fit.

2. The headset of claim 1 , wherein the circuitry is operatively coupled to the display assembly for rendering a visual indicator based on the frame fit signal.

3. The headset of claim 2 , wherein the visual indicator comprises an instruction for adjusting the frame.

4. The headset of claim 1 , wherein the motion data comprise position data with respect to time.

5. The headset of claim 1 , wherein the circuitry analyzes the motion data with respect to a coordinate system.

6. The headset of claim 5 , wherein the coordinate system is a multidimensional, spatial coordinate system.

7. The headset of claim 1 , wherein the circuitry analyzes the motion data using a maximum travel position of the frame as the maximum excursion and a return travel position of the frame.

8. The headset of claim 7 , wherein a time difference between a time of the maximum travel position and a time of the return travel position is less than two seconds.

9. The headset of claim 1 , wherein the circuitry analyzes the motion data for a loose frame fit artefact.

10. The headset of claim 9 , wherein the loose frame fit artefact degrades visualization of a rendering to the display assembly.

11. The headset of claim 1 , wherein the circuitry analyzes the motion data for a change in sign of acceleration.

12. The headset of claim 1 , wherein the motion sensor comprises an inertial sensor.

13. The headset of claim 1 , comprising a test mode that renders an instruction to the display assembly to instruct a wearer of the headset to perform an action.

14. The headset of claim 13 , wherein the frame fit signal is based on motion data acquired during the performance of the action.

15. The headset of claim 1 , comprising at least one of virtual reality circuitry and augmented reality circuitry.

16. The headset of claim 1 , wherein the frame comprises temples.

17. The headset of claim 1 , wherein the frame comprises a head strap.

18. A method comprising:
acquiring motion data via a motion sensor of a headset:
analyzing, via circuitry, the motion data to detect a rebound of the headset after a maximum excursion of the headset and to determine a metric to characterize looseness of fit using a geometric model for the rebound; and
issuing an instruction responsive to detection of the rebound.

19. The method of claim 18 , comprising rendering a visualization to a display assembly of the headset during the acquiring motion data.
