The Design And Implementation Of Cross-platform Stroke Input Method Engine

In recent years, as the growth of the number of smartphone users explosive,mobile phones have become the important tool of information processing. Chineseinput requirements appear in all aspects of mobile phone use, thus improve theuser’s input speed and the comfort level become urgent needs. Stroke input methodcurrently on the market have some mature application can give users a goodexperience, but on the radical input units and fault-tolerant still not that good.This paper summarizes results of previous studies, study many features of currentphone platforms, presents a cross-platform stroke input method engine with radicalinput, and the engine was validated and tested.This article first analyzed the mobile phone input method’s present developmentsituation at home and abroad, and compared the mainstream of the advantages anddisadvantages of two input method on the market, determine the stroke inputmethod described in this article need to be improved at phonetic prompt and strokefault tolerance. Then give a series of solutions to engine implementation of the codeacross platforms, memory management, and operation speed and a series of issues.Then detailed introduces the structure design of the whole system and the client, theengine parts manager, stroke engine adapter part, stroke engine kernel part,imagination engine adapter part, imagination engine kernel part. presents thedesign and implementation process of these parts in detail. Especially for the mostcomplex thesaurus structure and thesaurus search strategy section has carried on thedetailed narration. Finally, paper combine white-box testing method with black-boxtesting method test system by labor and automated test procedures, confirm thesystem achieved the expected requirements. Provides a new idea for other inputmethods employed for a further stroke input method optimization and improvement.
