Abstract
A wearable device can include an inward-facing imaging system configured to acquire images of a user's periocular region. The wearable device can determine a relative position between the wearable device and the user's face based on the images acquired by the inward-facing imaging system. The relative position may be used to determine whether the user is wearing the wearable device, whether the wearable device fits the user, or whether an adjustment to a rendering location of virtual object should be made to compensate for a deviation of the wearable device from its normal resting position.

1-20. (canceled)
A head-mounted device (HMD) comprising:
- a hardware processor programmed to:
- receive a set of sequentially captured images comprising a first image and a second image;
- determine whether at least one periocular feature of a user of the HMD is in at least one of the set of sequentially captured images;
- and
- in response to a determination that at least one periocular feature of the user is in the first image and not in the second image, provide an indication that the HMD is not properly positioned on the head of the user.
A head-mounted device (HMD) comprising:
- a hardware processor programmed to:
- calculate a measurement of a relative position between the HMD and a head of a user;
- receive a set of sequentially captured images;
- determine the relative position between the HMD and the head of the user based on an appearance of a periocular region of the user in at least one of the set of sequentially captured images;
- and
- determine a rendering location of a virtual object based, at least in part, on the relative position between the HMD and the head of the user.
