Toes are expected to perform various tasks by bending and stretching movements. However, to our knowledge, few studies have examined toe movement for operation. In particular, the characteristics of toe movements when used for operation have not been clarified. To investigate these characteristics, we proposed a new experimental evaluation system using wire displacement sensors. In this system, operators can move a marker shown on a PC screen by toe flexion and extension movements. In the experiment, 16 different operation patterns were considered, and the time required to finish the operation with one or two toes was measured and evaluated based on the average operation time. A comparison between toe flexors and extensors in operation time indicated that toe movements with a large angle were easier than those with a small angle if only one toe was used, but became more difficult if two toes were used. These results suggest that the ease or difficulty of toe movements differed depending on whether one or two toes are used. These results were then compared with those of additional evaluation experiments we conducted using fingers. The results indicated that toe operation requires 3.51 times more time than finger operation if two toes or fingers are used.

期望脚趾通过弯曲和伸展运动来执行各种任务。然而，据我们所知，很少有研究检查脚趾运动的操作。尤其是，脚趾运动用于操作时的特征尚未弄清。为了研究这些特性，我们提出了一种使用线位移传感器的新型实验评估系统。在该系统中，操作员可以通过脚趾的屈伸运动来移动PC屏幕上显示的标记。在实验中，考虑了16种不同的操作模式，并基于平均操作时间来测量和评估完成一两个脚趾操作所需的时间。脚趾屈肌和伸肌在操作时间上的比较表明，如果只使用一个脚趾，则大角度的脚趾运动比小角度的脚趾运动容易，但如果使用两个脚趾，脚趾屈伸运动则变得更加困难。这些结果表明，脚趾运动的难易程度取决于是使用一个还是两个脚趾。然后将这些结果与我们使用手指进行的其他评估实验的结果进行比较。结果表明，如果使用两个脚趾或手指，脚趾操作所需时间比手指操作多3.51倍。然后将这些结果与我们使用手指进行的其他评估实验的结果进行比较。结果表明，如果使用两个脚趾或手指，脚趾操作所需时间比手指操作多3.51倍。然后将这些结果与我们使用手指进行的其他评估实验的结果进行比较。结果表明，如果使用两个脚趾或手指，脚趾操作所需时间比手指操作多3.51倍。
