摘　　要：针对现有舱外航天服人机交互方式较为单一的问题,提出了一种利用头戴式增强现实显示技术与头戴式眼动仪相结合的眼动交互方法。使用目前已成熟的瞳孔角膜反射法实现了视线跟踪;设计了基于注视停留时间触发和长眼跳触发的眼动交互模式,实现了在增强现实显示界面的眼动人机交互。可用性评估结果表明该技术能够实现人眼注视方向的准确估计,具有对测试者侵扰程度低、眼控触发灵敏高效的优点,可有效提高航天员出舱活动任务的工作效率。Targeting the lack of effective human-computer interaction mode in existing extravehicular spacesuit,an eye movement interaction method combining head mounted augmented reality display technology with head mounted eye tracking device was proposed.The mature pupil-corneal reflex method was used for the eye tracking,and the eye movement human-computer interaction on the augmented reality display interface was realized by stay-time trigger mode and long eye-jump trigger mode.The system availability evaluation showed that accurate estimation of the gaze direction was realized with this method,and it had the advantages of little interference to the wearers and the robustness of the eye-control method.This approach could effectively improve the working efficiency of the astronaut’s extravehicular activity.
