The Research Of Mobile Phone Intelligence Inputting Method Based On Windows Mobile Platform

At present, with the rapid popularization of mobile devices such as PDAs, mobile phones, more and more applications and services are included in mobile devices, such as short message, send and receive E-mail and the handling of some files etc, the people are getting more and more strong demand for mobile devices which has a fast and efficient Chinese character input method. The paper has conducted the research on handset intelligence input method based on Windows Mobile platform, makes the input method can successfully run on the platform.Firstly, the feature of Windows Mobile system was introduced in this paper, and compared it with the PC Windows system, and gives the environment which the handset input method the development based on Windows Mobile the platform. For coding scheme of Input method system, the traditional mobile text input coding scheme are discussed and improved. Then discussion input method system design thought, including the input method system structure, working principle and realization process in the platform.It is an important component of the input method system that conversion user input digital keyboard string to Chinese code. This paper first discusses the design criterion of input based on mobile platform, then according to the characteristics of input text on cell phones, film subtitles as a source of thesaurus file and carries on screening and optimized processing to it in this paper. For the conversion of the input method outside code to code, this paper used the index trees to storage Chinese characters outside the code and code. In order to save the handset memory space, this paper carries on optimized processing to the traditional index tree, the index tree node merge, Constitute non-fixed-length structure to store the tree node. Due to the strokes is too many for Chinese, proposed one kind of fuzzy input concept and has given the corresponding algorithm for reduce the average code length of Chinese characters, realizes the incomplete inputs method for Chinese character input code.A statistical language model is given for the input method system of scheduling problem with the word dictionary, and designs a stroke code transformation process for the model. In order to meet users' requirements, this input method systematically increased self-learning modules and intelligent word input method based on N element language model. In the process of using, this method is more and more adaptable for user input habitIn the implementation of Mobile intelligent input method, because the IMM-IME structure is one of the core components of multi-language support for Windows Mobile system, for the realization of the input interface provides support. This paper discusses the basic principle of Chinese input method based on Windows Mobile system, then, detailed analysis of the structure of handset input method based on the IMM-IME, the work process and some key issues which involves in realization, it has provided the good technical support for input method realization. Then, we discuss some of the technical issues involved in the implementation process, and intelligence input operation process and eventually achieving results are given.In this paper, the characteristics of the mobile intelligent input method can achieve the input of phrase and sentence, which advantages of this method are the following, such as easy operation, relaxed learning and using, and giving users high efficient input way. Meanwhile, this method adds the self-learning modules, and automatically learns the phrases and sentences which are usually inputted by users, and improve Chinese character input speed and intelligent degree. In order to further reduce the user choices and the average code length of date keyboard inputting, in the environment of using binary group, it can realize the intelligent word input based on previous inputting Chinese, which reduces users' choices and increase the Chinese inputting efficiency. Finally, the research showed that these modules are used in mobile phones intelligent input method based on Windows Mobile platform, which has important practical significance.
