方块苗文键盘输入音形编码的优化
|
摘要
针对由"首构件音码+末构件音码+末笔画形码+结构类型形码"构成输入编码序列的方块苗文音形输入编码基本方法存在的键位码元负荷分布不均及连续击键速度较慢方面的不足,以键位码元负荷和键位相关速度当量分析为基础,对基本方法中的形码设计及其映射方式进行调整优化。对比分析结果表明:优化后方法合理均衡了键位码元负荷,将方块苗文输入时两种连续击键情况下的键位相关速度当量均值分别降低了8.6000%和7.8500%。输入测试实验证实:优化后方法在保持较高输入正确率的同时显著提高了方块苗文的有效输入速度。
A typical keyboard input method of square Hmong characters can be realized by an input encoding sequence as "first component phonetic code+last component phonetic code+last stroke shape code+structure type shape code".However,there exist two main drawbacks in this method,which are uneven key code-element load and slow keyboard successive character input speed.Focused on these bottlenecks,an optimized phonetic-shape encoding strategy is presented after modifying the design of shape code and related mapping method of square Hmong characters rooted in code-element load analysis and speed equivalence analysis of the relative-key keywords.Comparative analysis results and input test experiments demonstrate that the proposed method possesses several advantages.First,the key code-element load is balanced.Second,the average speed equivalences of the relative-key keywords in two different continuous strike cases in the process of square Hmong characters input are cut down by 8.6000%and 7.8500%respectively.Finally,the optimized method improves the effective input speed significantly while maintaining high accuracy.
