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.
