Abstract: Various implementations assess user interactions to trigger user interface responses. Some implementations associate user gaze with user interface elements using one or more criteria that enable interpreting the user's gaze in ways that are consistent with user intentions and/or expectations. In some implementations, a user's gaze is associated with a user interface element when the user gazes at the user interface element. When the gaze leaves the user interface element (e.g., intentionally or unintentionally), the association may be maintained or discontinued using one or more criteria to be consistent with user intentions and/or expectations. In some implementations, this involves determining whether to continue associating a user's gaze with a user interface element so that the gaze-to-element association is maintained in certain circumstances (e.g., blinks and saccades) but discontinued in other circumstances (e.g.

Abstract: Various implementations identify user input based on the intended display frame rate and the adjusted user data. For example, an example process may include obtaining user data associated with an activity of a user via a sensor in a physical environment. The process may further include obtaining an intended display frame rate corresponding to one or more portions of a user interface being presented within an extended reality (XR) environment, where the intended display frame rate includes an irregular timing between frames. The process may further include adjusting the user data based on the irregular timing of the intended display frame rate. The process may further include identifying user input to the user interface based on the intended display frame rate and the adjusted user data.

Abstract: Methods, devices, and systems, in some implementations, stabilize user interface element using a stabilization property that is determined based on assessing the user's movement, e.g., assessing a hand movement characteristic and a head movement characteristic. In one example, the stabilization property restricts movement of user interface elements in certain circumstances, e.g., based on based on head movement (e.g., angular speed), hand movement (e.g., pinch centroid angular speed), and/or hand translation (e.g., pinch centroid speed).
