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.
