2. What is Eye-Tracking Technology in Wearables? (Eye-Tracking best Smart Wearables)
How does eye-tracking work?
Eye-tracking in wearables is achieved through a combination of sensors, infrared cameras, and AI-driven software that capture and analyze eye movements. There are three main methods used in eye-tracking technology:
Infrared-based eye tracking
Uses infrared cameras and light sensors to track the reflection of light on the cornea and pupil.
Captures real-time gaze direction and movement patterns with high precision.
Commonly found in VR headsets, AR smartglasses, and high-end assistive devices.
Electroculography (EOG) sensors
Measure the electrical activity of the eye muscles to detect movement.
Often used in medical and accessibility-focused wearables.
Effective even when eyes are closed (e.g., detecting sleep stages).
AI and machine learning-based gaze tracking
Uses AI algorithms to interpret eye movement patterns and cognitive responses.
Enables gesture-based interactions, where looking at a specific point triggers an action.
Used in gaming, neuromarketing, and user experience research.
Main functions of eye-tracking wearables
Gaze-based navigation – Hands-free control of the device by looking at icons or menus.
