An IRVS Based Human-Machine Interaction System Using Head-and-Eye Coordination Movement

In this paper we introduce an eye-gaze tracking system using the changes of the user's head position. The system presents a new optical structure. In this structure we propose an algorithm based on the projection of the line of sight. With this algorithm, we can say goodbye to complicated arithmetic operations, and improve the system's response time, which indeed, ensures synchronization. We modify the algorithm so the system can match eye features of Asian users. Test of the system shows it has high accuracy and a good real-time response, which makes the users feel more comfortable when they are using this system.
