Eye Gaze

The direction and focus of a person's eyes during visual attention, used both as a communication signal and as a measurable indicator of cognitive processing. In sign language communication, eye gaze serves critical linguistic functions including marking grammatical relationships, regulating turn-taking, and conveying pronominal references. In accessibility and HCI research, eye gaze patterns are studied through eye-tracking technology to understand how users interact with interfaces and to develop gaze-based input methods for people with motor impairments.
