👁️ Eye-Tracking Technology What is Eye-Tracking? Eye-tracking technology measures where and how long a person looks at different areas of a visual interface, screen, or environment. It records eye movements , gaze points , and fixations , often in real-time. This technology provides insights into user attention, intent, and cognitive load — and serves both interaction and analysis purposes. 🔧 How It Works Eye-tracking systems typically use: Infrared or Near-Infrared Light: Illuminates the eye to detect reflections. Cameras/Sensors: Capture the position of the pupil and corneal reflection. Processing Software: Calculates gaze direction, fixation duration, saccades (quick movements), and blink rate. There are three main types of eye-tracking setups: Remote Eye-Trackers: Mounted below screens or integrated into monitors. Wearable Eye-Trackers: Glasses or headsets for mobile use. Embedded Systems: Built into VR/AR headsets or specialized devices. ...
