摘　　要：随着眼动跟踪技术的日益成熟,面向终端用户的视线输入产品问世,视线交互(Gaze-based Interaction)的实用性越来越高。然而,由于眼睛并不是与生俱来的控制器官,用户界面中无论动态或静态的各种视觉反馈,在视线交互过程中都可能干扰用户的眼动,从而影响视线输入(视点坐标)。因此,通过两个视线点击(Eye Pointing)实验,从视点的空间分布特征和视线交互的人机工效两个方面,系统地评估了目标颜色因素对视线交互的影响。结果表明,目标颜色这类静态视觉反馈虽然不影响用户凝视目标时视点坐标的稳定性,但的确会对用户的眼动扫视过程造成显著影响,从而影响视线点击任务的人机工效。特别是在视线移动距离较长的情况下,这种影响更为明显。Because eye tracking technologies become increasingly mature , there have been some gaze input devices for end users in the market, leading to the increasing practicability of gaze-based interactions. However, the eyes are not in- herent control organs, so the visual feedback scan probably interferes the eye movements of users, regardless of dynamic or static forms presented in user interfaces, thereby affecting gaze input. Using two eye pointing task experiments, this paper systematically evaluated the effects of target color on gaze-based interactions according to the spatial features of gaze points and the criteria of human performance. The results indicate that although the factor of target color does not significantly change the spatial features of gaze points during fixations for target acquisition, it can indeed affect the per- formance of users in eye pointing tasks, especially for the targets located at long distances.
