该文通过对现有智能手机上的输入方式进行分析,把输入法分解为中文、英文和数字三种不同的输入状态,再结合GOF一书中的状态设计模式,给出了一个基于有限状态机的智能手机输入模型,这种输入模型可以用于Windows mobile系统, Symbian的S60系统等多种智能手机系统上的输入法开发。这样不但能简化智能手机上输入法的开发工作,而且也为多种智能平台上的输入法维护和升级提供了方便。

The paper analyzes state-of-the-art IME models for intelligent mobile and then decomposes input state into three different states of inputting Chinese, English and numerals respectively. Based on the state design pattern given by GOF, the paper proposes an automata based IME model for the intelligent mobiles, which is compatible with many intelligent mobile system such as Windows Mobile Symbian S60 etc. The model can not only simplify development effort but also provide much convenience in maintenance and update of intelligent mobile IME.
