触屏手机输入法状态切换键的可用性研究

Usability Study on Status Switch Key of Input Methods in Touch- screen Mobile Phones

目的为优化触屏手机输入法状态切换键的使用。方法本研究采用实验室研究的方法,研究用户对不同切换按键图符的主观偏好以及不同位置布局的用户操作特点。结果 (1)中文、英文、数字、符号状态切换按键的最优图符分别为"中/英"、"abc"、"123"、"";(2)位置布局的操作绩效结果表明左靠中位置操作绩效最佳;(3)根据前两个结果改进的优化输入界面原型操作绩效要优于原始输入界面。结论对于状态切换键设计的改进确实能提高输入法的状态切换效率。

Objective The research aimed to optimize the usability of status switch of input methods in touch - screen mobile phone. Methods The experiment employed performance test to analyze the individual preferences for the status switch icon and the influence of the position layout on the users＇operation. Results （ 1 ） the optimal key icon of switching between Chinese, English, Number, and Symbols is,＂ 中/英＂, ＂abc＂,＂ 123＂, ＂ ds＂ ; （ 2 ） the result of position layout experiment shows that the optimal position is left close to the middle. （3） the optimization interface based on those experiments above is superior to the previous one. Conclusion It reveals that the efficiency of status switch can be improved by redesigning the position and icon of status switch key.
