摘要
目的研究三种按键特征因素(即按键大小、间距和形状)对触摸屏输入可用性的影响。方法本研究结合人因实验和分析,采用5按键大小×3间距×3形状的组内设计,对触摸屏输入可用性(即输入绩效和使用偏好)进行实验测试,被试为15位在校大学生,采用重复测量的方差分析处理数据。结果按键大小、间距和形状对输入绩效均有显著影响;按键大小和间距、按键大小和形状之间存在显著交互作用;用户偏好可能产生较优绩效的按键设计方式。结论三种按键特征因素的不同设计方式对触摸屏输入的可用性有显著影响。
Objective To examine the effects of three button characteristics （i. e. , button size, space and shape） on the usability of touch screen devices. Methods A 5 button size X 3 space X 3 shape within subjects de- sign was employed to examine the usability （ i. e. , input performance and use preference） of input tasks with touch screen devices in a human factors experiment. Fifteen undergraduate students participated in the study. Repeated measures analyses of variance （ANOVAs） were used for data analysis. Results Button size, space and shape had significant effects on task completion time and accuracy. In addition, there were significant interaction effects between button size and space, and between button size and shape. The users generally preferred button characteristics that could result in optimal input performance. Conclusion All the three button characteristics had significant effects on the usability of touch screen devices.
