Gaze-based interaction

Definition

Gaze-based interaction refers to a method of human-computer interaction that utilizes the user's gaze or eye movements to control and navigate digital environments. This technology often employs eye-tracking systems that detect where a user is looking, enabling actions such as selecting objects, scrolling through menus, or triggering responses based on focus. By leveraging natural visual attention, gaze-based interaction enhances user experience and accessibility, particularly in augmented and virtual reality settings.
