More Information
Summary:The invention relates to a calibration gaze tracker. A method includes displaying a plurality of visual elements. The method includes determining an expected gaze target based on the respective feature values of the plurality of visual elements, the expected gaze target indicating a first display area where a user of the device intends to gaze while the plurality of visual elements are being displayed. The method includes obtaining an image via an image sensor, the image including a set of pixels corresponding to pupils of a user of the device. The method includes determining, by a gaze tracker, a measured gaze target based on the set of pixels corresponding to the pupil, the measured gaze target indicating a second display area in which the user is measuring gaze. The method includes adjusting a calibration parameter of the gaze tracker based on a difference between the first display area indicated by the expected gaze target and the second display area indicated by the measured gaze target. 本公开涉及"校准凝视跟踪器。"本
