Eye gaze correction using pursuit vector

A system comprising a processor and computer executable instructions, that when executed by the processor, cause the system to perform acts comprising:

• identify a reported location from an eye tracking signal;
• take a snapshot of screen content in a region surrounding the reported location such that snapshot remains in its original location on the screen with the reported location within the region;
• animate the snapshot with an animation such that locations within the snapshot move in a predetermined path from the reported location;
• receive a pursuit vector responsive to the animation;
• calculate a correction factor from the pursuit vector;
• and
• apply the correction factor at the reported location to adjust the reported location to an actual location.

A computer storage medium comprising executable instructions that, when executed by a processor of a machine, cause the machine to perform acts comprising:

• determine whether an error rate exceeds a threshold;
• responsive to the error rate exceeding the threshold, performing acts comprising:
• identify a reported location from an eye tracking signal;
• take a snapshot of screen content in a region surrounding the reported location such that snapshot remains in its original location on the screen with the reported location at a center of the region;
• animate the snapshot with an animation such that locations within the snapshot move in a predetermined path from the center of the region;
• receive a pursuit vector responsive to the animation;
• calculate a correction factor from the pursuit vector;
• and
• apply the correction factor at the reported location to adjust the reported location to an actual location.
