为了改进现有键盘的字母布局,使之更能适用于汉字拼音输入法,该文根据键盘布局的设计原则、相关的科学原理和基于汉字、拼音字母使用频率的统计数据,设计出一种较为合理的、适用于汉字拼音输入法的键盘布局。该文从静态、动态工作量和左右手交替率三方面,与现有键盘的字母布局进行比较。在工作量方面,对于同一手指新的键盘布局依食指、中指、无名指、小指呈线性递减关系,较好地符合各手指实际可承受负荷量,而其左右手放宽条件下的交替率为0.748 33,分析数据可知新设计出的键盘字母布局在汉字拼音输入法的输入效率方面有着显著的提高。

In order to improve the current keyboard to better support the Chinese Pinyin IME, this paper suggests a new letter layout scheme based on the statistics on the frequencies Chinese Pinyin(phonetic alphabet). The new scheme is compared with the current keyboard layout from three aspectsthe static loading, dynamic loading and the alternate rate of the left and right hand. In terms of workload, there is a linear decline from the forefinger, the middle finger, the ring finger and little finger, which is better coordinating to the practical efficiency of each finger. And the alternate rate of left hand and right hand is 0.74833, which is a more relaxed condition. These statistic figures validate that the new design would significantly enhance the efficiency of the Chinese characters input.
