Gaze Input

An input method that uses eye-tracking technology to detect where a user is looking, enabling interaction with digital interfaces through eye movements such as fixation (dwelling on a target), smooth pursuit (following a moving target), or blinks. Gaze input is a critical alternative input method for people with severe motor impairments who cannot use traditional controllers, keyboards, or mice. In virtual reality, gaze input can trigger selections, navigate menus, and control camera movement, providing accessibility for users who lack the arm or hand mobility required by standard VR controllers.
