In this study, two experiments were conducted to examine spatial stimulus-response compatibility (SRC) effects for a horizontal visual display with hand and foot controls. In experiment 1, the hand and foot controls were in a hands above and feet below vertical plane, such that the display and controls were orthogonal to each other. In experiment 2, the foot pedals were moved forward and placed directly underneath the front row of signals, resulting in an additional horizontal display and control relationship. The results of experiment 1 revealed a strong orthogonal SRC effect, such that the best performance was for the front signals with hand controls and rear signals with foot pedals, which was not altered with the presence of horizontal location mappings in experiment 2. These findings indicate that the front-hand/rear-foot mapping relationship was quite robust with regard to changes in the relative locations of the hand and foot response devices. STATEMENT OF RELEVANCE: The results of this study provide useful ergonomics recommendations for designing control consoles with visual signals presented in a horizontal plane and control devices operated by hands and feet. They are helpful for improving efficiency and overall system performance in person-machine systems.
在这项研究中，进行了两项实验来检验水平视觉显示器与手和脚控制的空间刺激-反应兼容性（SRC）效应。在实验 1 中，手和脚的控制处于手高于脚低于垂直平面的位置，使得显示器和控制彼此正交。在实验 2 中，脚踏板向前移动并直接放在信号的前排下面，从而产生了额外的水平显示和控制关系。实验 1 的结果显示出强烈的正交 SRC 效应，即手控的前信号和脚踏板的后信号表现最佳，而实验 2 中的水平位置映射的存在并没有改变这一结果。这些发现表明，在手和脚反应设备的相对位置发生变化时，前手/后手映射关系非常稳健。
本研究的结果为设计具有水平平面呈现的视觉信号和通过手和脚操作的控制设备的控制台提供了有用的人体工程学建议。它们有助于提高人机系统的效率和整体系统性能。
