Eye-tracking technology brings a different human-computer interaction experience to users because of its intuitive, natural, and hands-free operation characteristics. Avoiding the Midas touch problem and improving the accuracy of interaction are among the main goals of the research and development of eye-control systems. This study reviews the methods and limitations of research on avoiding the Midas touch problem. For typical control clicking operations with low fault tolerance, such as mode switching and state selection in an eye-control system, this study proposes Magilock, a more reliable control triggering method with a high success rate in multi-channel eye-control systems. Magilock adds a control pre-locked mechanism between the two interactive steps of eye-control channel positioning control and other interactive channel triggering controls in the multi-channel eye-control system. This effectively avoids incorrect control triggering caused by multi-channel coordination disorder and gaze-point drift. This study also conducted ergonomic experiments to explore the lock and unlock times of the control pre-locked mechanism in Magilock. Taking into account the experimental data and subjective evaluation of the participants, we recommend setting the lock time and the unlock time of Magilock to 200 ms.

Magilock：多通道眼控系统中可靠的控制触发方法

眼动追踪技术因其直观、自然、免提的操作特点，给用户带来了不一样的人机交互体验。避免点石成金问题并提高交互的准确性是眼控系统研发的主要目标之一。本研究回顾了避免点石成金问题的研究方法和局限性。针对典型的低容错控制点击操作，例如眼控系统中的模式切换和状态选择，本研究提出了Magilock，这是一种在多通道眼控系统中具有较高成功率、更可靠的控制触发方法。 Magilock在多通道眼控系统中的眼控通道定位控制和其他交互通道触发控制的两个交互步骤之间增加了控制预锁定机制。这有效避免了多通道协调紊乱和注视点漂移导致的误控制触发。本研究还进行了人体工程学实验，探索 Magilock 控制预锁定机构的锁定和解锁时间。考虑到实验数据和参与者的主观评价，我们建议将 Magilock 的锁定时间和解锁时间设置为 200 ms。
