| 摘 要： | 设计了一个用于PC环境下的实时眼动跟踪系统，该系统通过对摄像机所采集的视频图像进行实时的图像处理，来判断用户当前对虚拟环境中对象的注视焦点。在瞳孔一角膜反光点向量法（PCCR）的基础上，提出了高效的基于最佳线性逼近预测的实时眼动跟踪算法。实验结果证明，该方法很好地解决了眼动跟踪的实时性问题。

| Abstract: | Eye-tracking as a new method of HCI has the merits of immediacy,high speed and naturalness.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(PCCR),the authors improved and realized a high efficient linear prediction algorithm for the real-time image-processing.Experiment proved that this algorithm can well support real-time eye-tracking as an ... |
