摘要

眼动跟踪技术作为一种新兴的交互手段

具有自然、高效和易于意图理解等优点.我们设计实现了一个桌面眼动跟踪系统作为虚拟装配系统的一个通道

通过摄像机实时采集视频并经过实时的图像处理判断用户对虚拟环境中对象的注视焦点.系统利用了瞳孔-角膜反射向量法理论

设计和实现了一个高效的实时眼动跟踪算法

即线性逼近预测算法.实验证明这一方法很好的解决了眼动通道的实时性问题.

Abstract

Eye-tracking as a new method of human computer interaction has the merits of naturalness

efficiency and easy intent under standing.The authors have designed a Desktop Eye-Tracking System which used the technique of image processing to obtain the user's gaze focus in virtual environment scene.Based on the theory of pupil center corneal reflection

the authors improved and realized a highly efficient linear prediction algorithm for real-time eye gaze image processing.Experiments proved that this algorithm can well support real-time eye-tracking as an interaction modality for desktop virtual environment.
