Abstract: A system and techniques for calibrating an eye tracking system are described. The system can update the calibration of personal calibration parameters continuously based on a user's gaze on a user interface, following user interface stimulus events. The system improves continuous calibration techniques by determining an association between the user's eye sequences and the stimulus events, and updates the personal calibration parameters accordingly. A record indicative of a user gaze, including eye sequences, such as eye movements or eye fixations, is maintained over a time period. A user interface stimulus event associated with the user interface and occurring within the time period is detected. An association is determined between the eye sequence and the user interface stimulus event. An interaction observation that includes the eye sequence and a location of the stimulus event is generated. Personal calibration parameters are updated based on the interaction observation.

Abstract: Computer-generated image data is presented on first and second displays of a binocular headset presuming that a user's left and right eyes are located at first and second positions relative to the first and second displays respectively. At least one updated version of the image data is presented, which is rendered presuming that at least one of the user's left and right eyes is located at a position different from the first and second positions respectively in at least one spatial dimension. In response thereto, a user-generated feedback signal is received expressing either: a quality measure of the updated version of the computer-generated image data relative to computer-generated image data presented previously; or a confirmation command. The steps of presenting the updated version of the computer-generated image data and receiving the user-generated feedback signal are repeated until the confirmation command is received. The first and second positions are defined based on the user-generated feedback signal.

Abstract: There is disclosed a computer implemented eye tracking system and corresponding method and computer readable storage medium, for detecting three dimensional, 3D, gaze, by obtaining at least one head pose parameter using a head pose prediction algorithm, the head pose parameter(s) comprising one or more of a head position, pitch, yaw, or roll; and to input the at least one head pose parameter along with at least one image of a user's eye, generated from a 2D image captured using an image sensor associated with the eye tracking system, into a neural network configured to generate 3D gaze information based on the at least one head pose parameter and the at least one eye image.
