The advanced micro projectors create reflection patterns on the eye. Images of the user and the reflection patterns, captured by the sensors, are used to calculate the exact position and gaze direction. We use near-infrared illumination to create reflections on the eyes that can be tracked with high accuracy. By using infrared light that is invisible to humans, the eye tracking system can work without being affected by ambient light conditions. It works in both light and dark environments.
- Avoid strong direct light on the tracker and in your eyes.
