Design Chinese Input Method In Embedded System Based On MiniGUI

Chinese input method is a necessary function of mobile phones, but chinese information processing technology,including the right to amend the core module of chinese character processing technology,is mainly controlled by overseas corporations. Within hundreds of millions of mobile phones used in China, more than 90% of them used foreign technology and our country have to pay a huge number of money for chinese input method every year. Chinese input method in embedded system is occupied by T9 of the Tegic telecommunications in America,Motorola's iTAP and EZIT of Zi Corporation in Canada.At present, some domestic mobile phone manufacturers use their own developed input method, but its performance is not satisfactory in many aspects, for example, slow response, difficult to use, weak association function. Many domestic corporations have engaged in development of chinese input method, but these input methods limits in foreign platform, which lead them difficult to generalize in practical application.This design has completed the two main modules of chinese input method: the module for searching chinese character and the module of association. At last, this chinese input method have been successfully integrated into MiniGUI.In the design of the searching module, speed is emphasized here. In view of the disadvantage of searching module in traditional chinese input method,this design have put forward a new method,which can greatly improve the speed of the searching module. This module provided the function to amend the NEIMA table.In the design of the association module, this design can not only improve the speed of association function,but also can limit the memorizer in a small size. Furthermore,this design have fully considered the extension of the new input method,and it very convenient for maintenance and revision.The application of chinese input method need the support of GUI,but design GUI in embedded system is a hard work,and this is the bottleneck for domestic input method to use in practical application. MiniGUI is developed by Beijing Feynman Software Technology Co.,Ltd and it is one of the most famous GUI in the world. MiniGUI is a successful free software in our country and it following the GPL terms. MiniGUI has great advantage in embedded system and it has widely used today. In order to let this input method widely used, this input method completed the MiniGUI's interface function of input method module, and it can convenient used in practical application.This input method has been tested with favorable results. It has rapid speed, better association function.
