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:
- an eye portion configured to face an eye of a user wearing the head mounted device,
- wherein the eye portion includes a display;
- at least one light emitter configured to emit light for illuminating at least a portion of a nose of the user;
- and
- 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.
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 configured to capture an image of at least a portion of the nose of the user;
- a memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors configured to:
- determine a shift or a rotation of the head mounted device relative to the user based at least in part on the image.
A method, comprising:
- obtaining, from an image sensor of a head mounted device, a first image of at least a portion of a nose of a user wearing the head mounted device;
- obtaining, from the image sensor of the head mounted device, a second image of at least a 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 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.
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, at least a portion of a nose of a user wearing the head mounted device;
- 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 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.
