Abstract: Methods to trigger eye enrollment without requiring good gaze interaction are described that allow a guest user of a device to initiate partial or full eye enrollment even though their eye model is not known and thus conventional gaze-based interactions do not work well. A gaze tracking system collects gaze data in the background. At any time (or within an interval after a user puts on the device), an eye enrollment can be triggered by detecting some gaze gesture, for example rolling the eyes in a large circle, or moving the eyes randomly for a time that exceeds a threshold. Depending on the coverage of the gaze/cornea data collected in the background, a full eye enrollment or only a visual axis enrollment may be performed in response to the gesture.

Abstract: A system for detecting a proximate object includes one or more cameras and one or more illuminators. The proximate object is detected by obtaining image data captured by the one or more cameras, where the image data is captured when at least one of the one or more illuminators are illuminated, determining brightness statistics from the image data, and determining whether the brightness statistics satisfies a predetermined threshold. The proximate object is determined to be detected in accordance with a determination that the brightness statistics satisfies the predetermined threshold.

Abstract: The invention relates to an eye tracking system (10) and a method for operating an eye tracking system (10) for determining if one of a left and a right eye of a user is dominant, wherein at least one image of the left and the right eye of the user is captured (S30), based on the at least one image and according to a predefined accuracy function a left accuracy score for the left eye (S34a) and a right accuracy score for the right eye (S34c) is determined and it is determined if one of the left and the right eye of the user is dominant in dependency of at least the left and the right accuracy score (S36). Thereby user-specific properties relating to his eyes can be provided and considered when performing eye tracking so that the robustness and accuracy of eye tracking can be enhanced.
