Patent number: 11941172Abstract: A method for training an eye tracking model is disclosed, as well as a corresponding system and storage medium. The eye tracking model is adapted to predict eye tracking data based on sensor data from a first eye tracking sensor. The method comprises receiving sensor data obtained by the first eye tracking sensor at a time instance and receiving reference eye tracking data for the time instance generated by an eye tracking system comprising a second eye tracking sensor. The reference eye tracking data is generated by the eye tracking system based on sensor data obtained by the second eye tracking sensor at the time instance. The method comprises training the eye tracking model based on the sensor data obtained by the first eye tracking sensor at the time instance and the generated reference eye tracking data.Type: GrantFiled: July 6, 2022Date of Patent: March 26, 2024Assignee: Tobii ABInventors: Carl Asplund, Patrik Barkman, Anders Dahl, Oscar Danielsson, Tommaso Martini, Mårten Nilsson

Patent number: 11675428Abstract: A system and a method for determining a gaze direction of a user viewing a scene is provided. The system comprises a camera for obtaining an image of at least one of the user's eyes, a depth information detection device for obtaining depth data related to the image, and a processing unit. The processing unit is configured to define a surface at a predetermined position relative to the user's eye based on the depth data, obtain a normalized image by projecting the image onto the surface and determine a normalized gaze direction based on the normalized image. The processing unit is further configured to determine a gaze direction based on the normalized gaze direction and the depth data.Type: GrantFiled: March 29, 2018Date of Patent: June 13, 2023Assignee: Tobii ABInventors: Oscar Danielsson, Daniel Johansson Torneus
