This paper first analyzed the significance and feasibility of applying eye tracking techniques in the study of drivers visual search characteristics of traffic signs.

This paper looks back the study history and puts forward basic concept and metrics definitions of eye tracking technology.

A short survey about eye tracking research work is given.

Application of gaze tracking in human computer interaction;

The application of new ergonomic technology in locomotive′s driving environment design is presented and analyzed from the aspects of anthropometry, human-machine geometry matching, gaze tracking, mental workload measurement and heat environment evaluation.

Implementation and optimization of the eye gaze tracking system based on DM642

In order to provide a straight, natural and bi-directional interaction method for the Augmented Reality (AR) system, a prototype system is proposed by integrating systems of eye gaze tracking and AR.

Infrared Eye-gaze Tracking System Research and Design;

This paper proposes a novel method for computing the eye-gaze direction and position in the eye-gaze tracking system.

An eye-gaze tracking method,which can make this system be automatically adapted to external lighting changes and the user s head movements freely,was put forward to alleviate the restriction on the user s head movements.

Eye-tracking technology has become an increasingly important research in the filed of Human-Computer Nature Interaction (HCNI).
