在某些工业检查过程中，出于效率或卫生原因，要求多工序处理工人在不使用手的情况下输入目视检查测试的结果。我们已经开发了一个免提视觉检测系统，通过使用扫视潜伏期，扫视眼球运动的时间特性。所提出的系统没有迈达斯触摸问题（即，由于难以区分有意的眨眼和注视与自然的眨眼和注视，开发眼睛打字界面的困难）。为了验证该系统，进行了一项实验，其中10名受试者进行视觉检查任务。平均缺陷检测率为99.4%，未观察到Midas触摸相关错误。误差分析结果表明，重新设计系统接口可以进一步提高系统性能。(c)2011 Wiley Periodicals，Inc.
In some industrial inspection processes, multiprocess-handling workers are required to enter the results of visual inspection tests without using their hands because of efficiency or hygiene reasons. We have developed a hands-free visual inspection system by using saccadic latency, a temporal characteristic of saccadic eye movements. The proposed system is free from the Midas touch problem (i.e., the difficulty in developing an eye-typing interface owing to the difficulty in differentiating between intentional blinks and gazes and natural ones). For verifying the system, an experiment was conducted in which ten subjects performed a visual inspection task. The average defect detection rates were 99.4%, and no Midas touchrelated errors were observed. Results of the error analysis showed that redesigning the system interface would lead to a further enhancement of the system performance. (c) 2011 Wiley Periodicals, Inc.
