标准缅甸辅音字符的位置，用户熟悉，让新手用户视觉搜索时间，可以优化提出了软键盘的布局。本文的以下部分安排如下：相关相关工作是在第2节中描述第3节为背景的地方和案例研究为缅甸语言软键盘在第4节解释实验结果，是专门在第5。本文的结论在第6。2相关工作至少自1980年，研究人员在HCI已经意识到Qwerty键盘的缺点作为一个软键盘的布局和设计了多种优化的软键盘布局与越来越复杂和更严格的优化方法。晓军碧14可见准Qwery软键盘通过采取用户熟悉自然与Qwerty键盘，具有准Qwerty键盘优化布局的想法可能显著减少新手用户视觉搜索时间。约翰Himberg1也利用2矢量量化算法，以产生一种自适应键盘与视觉在线反馈。对于非拉丁字符，PhavyOUK6attemped发展非QWERTY按键布局安排，并基于单词的预测文本输入方法为高棉语发音者拼字法和分组辅音和元音。牛建伟4试图生产中国输入法的触摸屏手机，它利用中国文字的象形性，使中国文字在手机上更快，更容易输入。对于语音的脚本语言（也称为复杂文本语言）在东南亚，缅甸的语言只有几个研究工作在键盘设计。对于多抽头电话，叶觉星期四9采用了基于缅甸语言字符书写的小型计算设备，如移动电话，PDA和电子词典等。然而，缅甸软键盘上的触摸屏手机位置的键映射的想法手15机还没有被设计从技术上看至今。在本文中，提出了软键盘是试图避免对键盘布局的开关，并加强缅甸的文字输入速度上的手机触摸屏。3背景在软键盘的按键布局的组织取决于各种因素，如关键的地方，那的人需要找到当前的关键和未来更喜欢密钥（也称为移动时间），大小的关键的关键，距离所需的时间和文本输入速度在每分钟字，如图1。3.1文字录入速度在文本输入速度也被称为字每分钟（WPM），可以通过取平均值呈时间（MT）的倒数，由每分钟60秒相乘并通过字符的平均数在一个字中分割计算方程1。3.2平均运动时间（MT）平均运动时间计算过，如公式2所示的所有可能的有向图。凡Pij是二元语法选择的概率Keyi时Keyj被选中，它可以由式（3）在数学上的估计。3.3动作时间（MT）为了计算运动时间，菲茨定律是制定数学上根据公式4。MT是从移动到另一个给定的距离和，如图所示的密钥大小的时候Greece第一次奥运会a和b是经验确定的系数。163.4搜索时间用于搜索的时间计算，希克-海曼定律可以用数学假设用户选择其中的候选键计算平均反应时间（RT）根据式（5），其中n是键在键盘的数量，是给定n个关键常数，其值是根据经验确定的。4，缅甸软键盘：案例研究缅甸脚本是一个非字母的脚本。相反，像其他婆罗米脚本，它是元音或辅音和元音符号的其中一个组成音节脚本。有34个辅音（，等），一个比拉马或devowelizer号（），11依赖元音符号（，等。），7个独立的元音（，等），4内侧的迹象（，），2音调符号标志（，），10个数字（0,1，2,3等），4种不同的标志（，）和在基本缅甸字符2标点符号（，）7。在Android平台上的拉丁软键盘只有26那些被设置为输入字符设备，如图3键。4.1在触摸屏目前的缅甸软键盘在缅甸的语言，需要75个字符的小型手持设备设置。传统的目前使用的缅甸软键盘是由排名频繁使用的字符为基础的拉丁软键盘。最频繁使用的字符（辅音字符）被放置于布局的顶部，而其余的字符与一些控制键的使用。大多数情况下，三个键盘布局都需要输入缅甸文字。在第一个布局，常用的辅音被放置在优先级。其余的依赖元音，17devowelizer标志，内侧体征和音调符号的符号是在第二布置与第三布置为缅甸位数，各种符号和标点符号如在图4中说明。目前使用的缅甸软键盘的关键问题是它的过度需求上的控制键来切换键盘布局。分析缅甸的句子后，从布局1和布局2一些字符必须特别是在总决赛情况下经常结合起来，如，等。此外，要在缅甸语言一个音节，辅音在布局结合某些键2，它可以加载过多的版式切换时间。例如，要输入缅甸短句“”嗨朋友，你在做什么？，15开关时间是需要输入9个音节。此外，类型的作家缅甸键盘布局是软键盘的触摸屏设备上的另一种尝试，如图5。传统型作家根据缅甸键盘布局是在个人计算机上正式使用，取得了理想的打字性能。移植类型的作家的键盘布局，手机，某些字符仍然留下的布局和用户后面不能容易地与单个手指或小型手持设备两个拇指输入文本。4.2提出了软键盘布局的实现因此，提出的系统尝试开发缅甸软键盘输入文字缅甸与新用户的学习时间短，以减少键盘布局切换时间。有高效率的投入，频繁的单字组频率使用辅音和元音是需要知道有一个布局放置有效率的方式。分析现实生活中的采访从Unicode标准的收集132174句子之后跟着缅甸网站，缅甸字符单字组的频率是不同的，如图6，7和8。在语料库的建设，访谈的主题选取20个不同的类别，以避免语料库在一个域中的偏见。18通过取所述解析缅甸字符单字组频率和字符结合使用模式，软键盘的布局设计。软键盘的设计包含三种布局。在第一布局中，最频繁使用的辅音字符（高于阈值的虚线描绘了在图6和7）的交错依赖元音字符来减少手势动作时间根据从算法1中的文本输入速度的实验结果，作为在算法中所示，n是关键的软键盘的按键数为29，A，B和b用经验系数为0.5。WIJ假定为软键盘的触摸屏手机的像素长度。dij为可依和keyj之间的长度。对于每一个随机产生的密钥布局，分析文字输入速度和打印输出到日志19文件。Algorithm-1:TextEntrySpeedAssumingtheinputsaren,Dij,Wij,Pij,a,bandbbeginif(diagonal)Dij:=(len12+len22);elseDij:=Wij*len;Pij:=Bigram(keyi,keyj);endifRT:=b*log2(n+1);repeatgenerate_random_layout();MTij=a+b*log2(Dij/Wij+1);Calculate_MT();Analyze_Entry_Speed();Print_to_File();until(nn)end从日志文件输出，选择最好的10的布局，并
