摘　　要：基于自主设计并实现的视线追踪方案,提出一套新的有广泛应用前景的人机交互方法,并构建了一个仿真原型系统。首先,利用机器视觉技术实现了非穿戴式的实时视线追踪,并采用带头动补偿的视线方向计算模型体系,使得视线追踪能适应操作者头部在一定范围内的活动。面向交互,根据眼动心理学的相关理论提出了基于眼动状态的有意眼动命令识别方法。实际测评结果表明,这样既提高了眼动命令输入的有效性,同时也减少了实时眼动输入给操作者带来的困扰,使人机交互的过程更加自然、和谐。A very promising interactive way between human and computer based on gaze tracking was proposed, and a simulation system was created. A scenario of non-contact gaze tracking using machine vision technology was described at first. To allow for the head motion of the user, a gaze-direction calculating model system with head movement compensation was presented Then according to the theory of Eye-movement Psychology, the method of conscious command recognition based on eye movements was brought in to make the interaction more naturally. Experiment results demonstrate, this method can not only promote the effectiveness of the input command, but also lessen the user＇s burden caused by gaze input.
