触摸屏具有直观的可操作性，因此近年来这些触摸屏已经在各种设备中流行起来。特别是在小型设备中得到了广泛的应用。手机、音乐播放器、PDA 等。这些小型设备具有可以轻松随身携带的特点。我们还倾向于用一只手操作这些设备。因此，需要指出的是，需要一种适合单手操作的屏幕界面。然而，目前还没有足够的知识用于触摸屏的界面设计。在本研究中，为了定义开关尺寸和形状易于操作的条件，我们评估了开关尺寸和形状对其错误率和指向时间的影响。本实验的受试者为15名健康男性。他们被要求在35种开关条件下对触摸屏进行操作。结果表明，合适的开关尺寸可以提高便携式触摸屏的可用性。此外，发现当开关形状垂直长或水平长时，错误率、指向时间和主观操作容易性变得更差。
The touch-sensitive screens have intuitive operability, thus these touch-sensitive screens have become popular with a variety of devices in late years. In particular, it has come into widespread use in small devices; cellular phones, music players, PDA and so on. These small devices have the feature that it is possible to carry them around easily. There is also tendency that we operate these devices by one hand. Therefore, it is pointed out that the screen interface appropriate to one-handed operation is required. However, there is not knowledge enough to use for interface design of touch-sensitive screen. In this study, for the purpose of defining the condition of switch size and shape is easy to operate, we evaluated influence of switch size and shape on their error rate and pointing time. The subjects of this experiment are 15 healthy male. They were asked to operate on touch-sensitive screen under 35 conditions of switches. The results show that there is an appropriate switch size that improves the usability of portable touch-sensitive screen. Furthermore, it is found that error rate, pointing time and subjective easiness of operation become worse when the switch shape is vertically long or horizontally long.
