System for performing eye detection and/or tracking

A method comprising:

• generating, using a first imaging device having a first field of view, first image data at a first frame rate, the first image data representing a user;
• determining that a portion of the first image data represents a face of the user;
• causing, based at least in part on the portion of the first image data, an actuator associated with a second imaging device having a second field of view smaller than the first field of view, to move from a first position to a second position;
• generating, using the second imaging device, second image data at a second frame rate lower than the first frame rate, the second image data representing at least an eye of the user;
• determining, based at least in part the second image data, an eye position of the user;
• and
• outputting data associated with the eye position of the user.

A system comprising:

• a first imaging device having a first field of view;
• a second imaging device having a second field of view smaller than the first field of view;
• an actuator for positioning the second imaging device;
• one or more processors;
• and
• one or more computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• generating, using the first imaging device, first image data representing a user;
• determining, using the first image data, a location of a face of the user;
• causing, based at least in part on the location, the actuator to move from a first position to a second position;
• generating, using the second imaging device, second image data representing at least an eye of the user, wherein the second image data has at least one of a lower resolution or a lower frame rate than the first image data;
• determining, using the second image data, at least one of an eye position or a gaze direction of the user;
• and
• outputting data representing at least the one of the eye position or the gaze direction of the user.
