Abstract
Head pose information may be determined using information describing a fixed gaze and image data corresponding to a user's eyes. The head pose information may be determined in a manner that is disregards facial features with the exception of the user's eyes. The head pose information may be useable to interact with a user device.
Claims20
A sensor device, comprising:
- an image sensor;
- a memory configured to store computer-executable instructions;
- and
- a processor in communication with the memory and configured to execute the computer-executable instructions to at least:
- access gaze information corresponding to at least one user eye;
- determine that the at least one user eye is in a gaze state based at least in part on the gaze information;
- in response determining that the at least one eye is in the gaze state, access image data from the image sensor, the image data corresponding to at least an eye region that includes the at least one eye in the gaze state;
- and
- determine head pose information based at least in part on the image data corresponding to the eye region, the head pose information defining at least a position of a user head and an orientation of the user head.
6 more elements
A computer-implemented method, comprising:
- accessing an indication that at least one eye is in a gaze state;
- in response to accessing the indication, accessing image data corresponding to an eye region that includes the at least one eye in the gaze state;
- and
- determining head pose information based at least in part on the image data corresponding to the eye region.
1 more element
One or more non-transitory computer-readable storage devices storing computer-executable instructions that, when executed by one or more computer systems, cause the one or more computer systems to perform operations comprising:
- instructing collection of image data corresponding to an eye region that includes at least one eye of a user;
- inputting the image data into an artificial intelligence model;
- and
- determining at least one of head position or a head orientation based at least in part on output from the artificial intelligence model.
