    Abstract: Examples relating to calibrating an estimated gaze location are disclosed. One example method comprises monitoring the estimated gaze location of a viewer using gaze tracking data from a gaze tracking system. Image data for display via a display device is received, the image data comprising at least one target visual and target visual metadata that identifies the at least one target visual. The target visual metadata is used to identify a target location of the at least one target visual. The estimated gaze location of the viewer is monitored and a probability that the viewer is gazing at the target location is estimated. The gaze tracking system is calibrated using the probability, the estimated gaze location and the target location to generate an updated estimated gaze location of the viewer.

    Abstract: Embodiments that relate to scaling a visual element displayed via a display device are disclosed. In one embodiment a method includes receiving and using gaze tracking data to determine gaze locations at which a user is gazing on the display device. Depth tracking data is received and used to determine that a user's pointer is at a predetermined location. In response, a locked gaze location on the screen is locked, where the locked gaze location includes at least a portion of the visual element. In response to locking the locked gaze location, the visual element is programmatically scaled by a predetermined amount to an enlarged size. A user input selecting the visual element is then received.

    Abstract: Embodiments that relate to positioning a target indicator via a display system are disclosed. For example, one disclosed embodiment provides a method for positioning a target indicator using gaze tracking data having a coarse accuracy from a gaze tracking system of a computing device. Head pose data having a fine accuracy greater than the coarse accuracy is received from a head tracking system. Using the gaze tracking data, an approximate user gaze region within a display region is determined, and the target indicator is displayed at an initial location within the approximate user gaze region. A reposition input from the user is received. In response, subsequently received head pose data is used to calculate an adjusted location for the target indicator. The target indicator is then displayed at the adjusted location.
