1. A method comprising:
receiving, by processing circuitry and from a gaze tracker, gaze tracker output data that indicates a gaze location on a display at which a user is gazing, the gaze location indicating a pixel of a display;
determining, by the processing circuitry, an expected dwell region to which the user is expected to gaze after the gaze location, the expected dwell region is a range of pixels;
receiving, by the processing circuitry and from the gaze tracker, further gaze tracker output data that indicates a subsequent gaze location on the display at which the user is gazing; and
calibrating, by the processing circuitry and based on the subsequent gaze location and the expected dwell region, a location of a visual gaze indicator on the display resulting in a calibrated visual gaze indicator.
