Abstract
In some aspects, a head mounted device may include an eye portion configured to face an eye of a user wearing the head mounted device, where the eye portion includes a display. The head mounted device may include at least one light emitter configured to emit light for illuminating at least a portion of a nose of the user. The head mounted device may include at least one image sensor configured to capture an image of at least a portion of the nose of the user for use in determining a shift or a rotation of the head mounted device relative to the user. Numerous other aspects are provided.
Claims30
A head mounted device, comprising:
- a first eye portion configured to face a first eye of a user wearing the head mounted device,
- wherein the first eye portion includes a display;
- a second eye portion configured to face a second eye of the user;
- at least one light emitter configured to emit light for illuminating at least a portion of a nose of the user;
- a bridge portion that is:
- between the first eye portion and the second eye portion, and
- above a bottom of the first eye portion and above a bottom of the second eye portion;
- at least one image sensor positioned:
- at a nose-facing side of the bridge portion, and
- closer to the second eye portion than the first eye portions;
- and
- one or more light guides that:
- one or more of extend along a nose-facing side of the bridge portion, extend parallel to or follow a path of the bridge portion, or are embedded within the bridge portion, and
- are between the first eye portion and the at least one image sensor,
- wherein the at least one image sensor is configured to capture an image of at least the portion of the nose of the user for use in determining a shift or a rotation of the head mounted device relative to the nose of the user.
12 more elements
A system, comprising:
- a light emitter configured to emit light for illuminating at least a portion of a nose of a user wearing a head mounted device;
- an image sensor positioned at a bottom side of a bridge portion of the head mounted device and configured to capture an image of at least the portion of the nose of the user,
- the bridge portion being between:
- a first eye portion, of the head mounted device, configured to face a first eye of the user, and
- a second eye portion, of the head mounted device, configured to face a second eye of the user,
- the bridge portion being above a bottom of the first eye portion and above a bottom of the second eye portion, and
- the image sensor being further positioned closer to the second eye portion than the first eye portion;
- one or more light guides that:
- one or more of extend along the bridge portion, extend parallel to or follow a path of the bridge portion, or are embedded within the bridge portion, and
- are between the first eye portion and the image sensor;
- and
- one or more processors configured to:
- determine a shift or a rotation of the head mounted device relative to the nose of the user based at least in part on the image.
10 more elements
A method, comprising:
- obtaining, from an image sensor that is positioned at a bottom side of a bridge portion of a head mounted device, a first image of at least a portion of a nose of a user wearing the head mounted device,
- the bridge portion being between:
- a first eye portion, of the head mounted device, configured to face a first eye of the user, and
- a second eye portion, of the head mounted device, configured to face a second eye of the user,
- the bridge portion being above one or more light guides,
- the one or more light guides being:
- above a bottom of the first eye portion,
- above a bottom of the second eye portion, and
- between the first eye portion and the image sensor, and
- the image sensor being further positioned closer to the second eye portion than the first eye portion;
- obtaining, from the image sensor, a second image of at least the portion of the nose of the user;
- determining, based at least in part on the first image and the second image, a shift or a rotation of the head mounted device relative to the nose of the user;
- and
- adjusting a calibration used for eye tracking of the user based at least in part on the shift or the rotation of the head mounted device.
11 more elements
A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a head mounted device, cause the head mounted device to:
- monitor, using an image sensor that is positioned at a bottom side of a bridge portion of the head mounted device, at least a portion of a nose of a user wearing the head mounted device,
- the bridge portion being between:
- a first eye portion, of the head mounted device, configured to face a first eye of the user, and
- a second eye portion, of the head mounted device, configured to face a second eye of the user,
- the bridge portion being above one or more light guides,
- the one or more light guides being:
- above a bottom of the first eye portion,
- above a bottom of the second eye portion, and
- between the first eye portion and the image sensor, and
- the image sensor being further positioned closer to the second eye portion than the first eye portion;
- determine, based at least in part on monitoring the nose of the user, a shift or a rotation of the head mounted device relative to the nose of the user;
- and
- adjust a calibration used for eye tracking of the user based at least in part on the shift or the rotation of the head mounted device.
