DETERMINATION OF POSITION OF A HEAD-MOUNTED DEVICE ON A USER
First Claim
1. ) A method for determining if a head-mounted device for extended reality (XR) is correctly positioned on a user, the method comprising:
- performing eye tracking, using processing circuitry, by estimating, based on a first image of a first eye of the user, the position of the pupil of the first eye in two dimensions;
determining, using the processing circuitry, if the head-mounted device is correctly positioned on the user, by;
determining whether the estimated position of the pupil of the first eye is within a predetermined allowable area in the first image; and
(i) if the determined position of the pupil of the first eye is inside the predetermined allowable area of the first image;
concluding that the head-mounted device is correctly positioned on the user, or(ii) if the determined position of the pupil of the first eye is outside the predetermined allowable area of the first image;
concluding that the head-mounted device is incorrectly positioned on the user.

Abstract
There is provided a method and system for determining if a head-mounted device for extended reality (XR) is correctly positioned on a user, and optionally performing a position correction procedure if the head-mounted device is determined to be incorrectly positioned on the user. Embodiments include: performing eye tracking by estimating, based on a first image of a first eye of the user, a position of a pupil in two dimensions; determining whether the estimated position of the pupil of the first eye is within a predetermined allowable area in the first image; and, if the determined position of the pupil of the first eye is inside the predetermined allowable area, concluding that the head-mounted device is correctly positioned on the user; or, if the determined position of the pupil of the first eye is outside the predetermined allowable area, concluding that the head-mounted device is incorrectly positioned on the user.
