Abstract

Developing more effective and efficient Chinese character input methods has the potential to help Chinese mobile phone users (currently 320 millions) input text messages. iTAP(R) supports input based on the writing structure of Chinese characters. Current keypad graphics include three items: digits (0-9), letters (A-Z), and symbols that represent the minimum writing units of Chinese characters (strokes). Our study revealed the difficulties of mapping these strokes to individual keys using the current symbols. We present a case study illustrating the user-centered redesign of these symbols. The new symbols allow for faster entry speeds and lower error rates as compared to the current commercial solution. Results with our solution were also favorable when compared to Pinyin, a popular crosscultural solution relying on the Roman alphabet. The new design is in the process of being integrated into commercial mobile phones for users who would prefer native input methods for Chinese.
