【摘要】 本文回顾视线跟踪技术的发展历史,从原理上分为为基于光学和非光学的两类进行横向比较。文章重点对现有成熟的5类2D视线跟踪技术进行原理剖析并揭示其内在联系。通过分析2D技术存在的问题,进一步介绍了当今3D视线跟踪技术的原理和分类,并指出无论是基于模型还是非模型的3D技术,其核心思想都是在2D的基础上获得眼动的空间信息。最后给出理想视线跟踪系统的评价标准和未来在人机交互方向的应用发展趋势。更多还原

【Abstract】 A review of eye gaze tracking technology is presentend in this paper.First,from the view of history development,we horizontally categorize eye gaze tracking technologies into Camera-Based and non Camera-Based groups.Then,we further analyses five types of well-developed 2D Camera-Based technology and its inner relationship.For the intrinsic problems of 2D systems,the advanced 3D technology is introduced and discussed.The paper points out,theoretically,any 2D technology can be extended to 3D if only the absolute 3D position of the eye can be determined.Finally,we present the requirements of an ideal eye tracker for expected general computer interface and the future trends of eye gaze tracking technology on HCI.更多还原
