Selection using eye gaze evaluation over time

A data-holding device, comprising an eye tracking system, holding instructions executable by a logic device to:

• sample eye gaze samples via the eye tracking system;
• store the eye gaze samples;
• detect a selection input made via a user input mechanism other than the eye tracking system, at a time when an eye gaze location intersects a first user interface object;
• upon receipt of the selection input, evaluate a plurality of the eye gaze samples at different eye gaze locations and at different times within a time window selected based on the time at which the selection input is detected to determine a combined location of the plurality of the eye gaze samples;
• when the combined location of the plurality of the eye gaze samples is closer to a second user interface object than the first user interface object, then select the second user interface object as a result of the selection input and based on the second user interface object having a highest weighting according to a selection rule;
• evaluate a different plurality of the eye gaze samples in the time window to determine a combined location of the different plurality of the eye gaze samples;
• and
• confirm the selecting of the second user interface object or select a different user interface object as a result of the selection input based upon the combined location of the different plurality of gaze samples.

A head-mounted display device, comprising:

• a display configured to display a graphical user interface including one or more user interface objects;
• an eye tracking system configured to detect a location at which an eye gaze of a wearer of the head-mounted display device intersects with the display;
• a logic device;
• and
• a data-holding device holding instructions executable by the logic device to:
• sample eye gaze samples via the eye tracking system;
• store the eye gaze samples;
• detect a selection input made via a user input mechanism other than the eye tracking system, at a time when an eye gaze location intersects a first user interface object,
• upon receipt of the selection input, evaluate a plurality of the eye gaze samples at different eye gaze locations and at different times within a time window selected based on the time at which the selection input is detected to determine a combined location of the plurality of the eye gaze samples, and
• when the combined location of the plurality of the eye gaze samples is closer to a second user interface object than the first user interface object, then select the second user interface object as a result of the selection input;
• evaluate a different plurality of the eye gaze samples in the designated time window to determine a combined location of the different plurality of the eye gaze samples;
• and
• confirm the selecting of the second user interface object or select a different user interface object as a result of the selection input based upon the combined location of the different plurality of eye gaze samples.
