Abstract
A gaze tracking system comprising a pupil detection unit operable to detect the location of a pupil in one or more images captured of one or both a user's eyes, a confidence value determination unit operable to determine a confidence value in dependence upon the identified pupil position, the confidence value indicating an expected reliability of the detection of the pupil location, and a processing unit operable to generate, in dependence upon the determined confidence value, one or more outputs to cause the user to modify their pupil location to a location with a higher determined confidence value.

A gaze tracking system comprising:
- a pupil detection unit operable to detect the location of a pupil in one or more images captured of one or both a user's eyes;
- a confidence value determination unit operable to determine a confidence value in dependence upon the identified pupil position, the confidence value indicating an expected reliability of the detection of the pupil location;
- and
- a processing unit operable to generate, in dependence upon the determined confidence value, one or more outputs to cause the user to modify their pupil location to a location with a higher determined confidence value.
A gaze tracking method comprising:
- detecting the location of a pupil in one or more images captured of one or both a user's eyes;
- determining a confidence value in dependence upon the identified pupil position, the confidence value indicating an expected reliability of the detection of the pupil location;
- and
- generating, in dependence upon the determined confidence value, one or more outputs to cause the user to modify their pupil location to a location with a higher determined confidence value.
A non-transitory machine-readable storage medium which stores computer software which, when executed by a computer, causes the computer to perform a gaze tracking method comprising:
- detecting the location of a pupil in one or more images captured of one or both a user's eyes;
- determining a confidence value in dependence upon the identified pupil position, the confidence value indicating an expected reliability of the detection of the pupil location;
- and
- generating, in dependence upon the determined confidence value, one or more outputs to cause the user to modify their pupil location to a location with a higher determined confidence value.
