Precise eye and gaze tracking

Precise eye gaze tracking technology can be used in several sectors such as advance HMI. Vicomtech-IK4 is working on a complete solution for high precision eye tracking and gaze estimation using Pupil Centre Corneal Reflection technique (PCCR). A light source is used to cause reflection patterns on the cornea and pupil of the tested person. A camera is then used to capture an image of the eye. The direction of the gaze is then calculated using the angles and distances.
