Abstract
Methods for using a head mounted display (HMD) can detect slippage of the HMD through the use of a comparison between, for example, a calibrated glint reference point and a glint reference point calculated during monitoring of glints during usage of the HMD.
Claims20
A method for using a head mounted display, the method comprising:
- determining a first set of one or more glint reference points derived from one or more glints that were imaged during a calibration of a glint system in a head mounted display (HMD);
- monitoring glints during usage of the HMD after the calibration of the glint system;
- determining, in response to the monitoring of glints, a second set of one or more glint reference points derived from one or more glints that were imaged during the monitoring;
- detecting slippage of the HMD in response to detecting a difference between the first set of one or more glint reference points and the second set of one or more glint reference points.

A method for using a head mounted display, the method comprising:
- determining a first set of one or more glint reference points derived from one or more glints that were imaged while a viewer gazed in a predetermined direction during calibration of a head mounted display (HMD);
- monitoring glints during usage of the HMD after calibration of the glint system;
- determining, during the usage of the HMD, the viewer is gazing in the predetermined direction and in response determining whether to compensate for slippage.
