Eye Tracking

Technology that detects and follows the movement of a user's eyes, enabling gaze-based interaction, attention monitoring, and foveated rendering. In accessibility contexts, eye tracking serves as an alternative input method for users who cannot use traditional controllers, keyboards, or mice due to motor impairments. In VR, eye tracking integrated into head-mounted displays can enable gaze-based selection, menu navigation, and even locomotion control. Eye tracking also enables foveated rendering (concentrating graphical detail where the user is looking), which can improve VR performance and reduce simulator sickness.
