Abstract
A method for tracking eye movement is provided. One embodiment of the method includes receiving a first measurement from a first sensor configured to detect a gaze location, determining an initial gaze location based at least on the first measurement, receiving at least one of eye motion amplitude and eye motion direction measurement from a second sensor, and determining an estimated gaze location based at least on the initial gaze location and the at least one of eye motion amplitude and eye motion direction. Systems perform similar steps, and non-transitory computer readable storage mediums each store one or more computer programs.
Claims35
A method comprising:
- receiving a first measurement from a first sensor configured to detect a gaze location;
- determining an initial gaze location based at least on the first measurement;
- receiving a second measurement from a second sensor;
- and
- determining an estimated gaze location by combining at least the initial gaze location and a value related to eye motion that is based on the second measurement received from the second sensor.
A system comprising:
- a first sensor configured to detect a gaze location;
- a second sensor;
- and
- a processor communicatively coupled to the first sensor and the second sensor, the processor being configured to:
- receive a first measurement from the first sensor;
- determine an initial gaze location based on the first measurement;
- receive a second measurement from the second sensor;
- and
- determine an estimated gaze location by combining at least the initial gaze location and a value related to eye motion that is based on the second measurement received from the second sensor.
A system comprising:
- a first sensor configured to detect a gaze location;
- a second sensor;
- and
- a processor communicatively coupled to the first sensor and the second sensor and configured to determine an estimated gaze location during a data reporting interval of the first sensor by combining at least an initial gaze location and a value related to eye motion that is based on a measurement made by the second sensor.
A non-transitory computer readable storage medium storing one or more computer programs configured to cause a processor based system to execute steps comprising:
- receiving a first measurement from a first sensor configured to detect a gaze location;
- determining an initial gaze location based at least on the first measurement;
- receiving a second measurement from a second sensor;
- and
- determining an estimated gaze location by combining at least the initial gaze location and a value related to eye motion that is based on the second measurement received from the second sensor.
