Description

连续字母键盘 技术领域
本发明涉及输入设备技术领域，具体涉及一种连续字母键盘。
背景技术
键盘作为计算机设备中一个十分重要的部件，主要承担着向计算机发出命令或输入数据等功能。传统的“QWERTY键盘”(柯蒂键盘)的输入结构，为了避免打字过程中出现卡顿的问题，通常将26个字母分散设置以减少机械故障发生的概率。
QWERTY键盘的字母排列杂乱无序，连续字母很少，输入英文速度较慢。地球上用汉语的人超过15亿。其中大多数人使用拼音输入法。现有键盘的字母布局没有针对汉语拼音进行优化。
针对QWERTY布局的缺点，有许多新的键盘布局，比如1936年专利US2040248的Dvorak布局、1974年专利US3847263的X布局、2003年专利CN0221635的敏捷型布局、2006年专利US7137749的XPeRT布局。这些新布局的英文打字速度比QWERTY布局，提高约10至20％。缺点是英文打字速度提高有限，连续字母很少，尤其是不适合汉语拼音输入。
专利US7137749提供了英文字母频率表。

发明内容
基于此，提出了一种连续字母键盘，用于输入字母的按键排列有序，输入汉语拼音和英文速度快，能够适应信息时代使用需求。
其技术理论是：
1、高频辅音字母全部设在左侧键区，元音字母全部设在右侧键区。
2、常用字母对设在同行1列-4列、同行7列-10列。
3、高频字母设在最易击打的键位，以及次易击打的键位。
4、最难击打的键位设为低频字母或符号。
5、连续字母尽量放在同一行或同一列。
其技术方案如下：
一方面，提供了一种连续字母键盘，所述连续字母键盘的字母键区包括3行10列共30个键位；从左至右，第1列至第5列为左侧键区，第6列至第10列为右侧键区；从左至右，第1行依次为第1键位至第10键位，第2行依次为第11键位至第20键位，第3行依次为第21键位至第30键位；其中，第2键位、第3键位、第4键位依次用于输入字母R、S、T或T、S、R或R、T、S，第12键位、第13键位、第14键位依次用于输入字母H、N、G或G、N、H或G、H、N，第17键位、第18键位、第19键位依次用于输入字母E、I、A或I、E、A或A、I、E，第7键位、第8键位用于输入字母U、O。
上述实施例的连续字母键盘，高频辅音字母全部设在左侧键区，元音字母全部设在右侧键区，便于使用。
下面进一步对技术方案进行说明：
在其中一个实施例中，第9键位、第10键位用于输入字母Z、符号“；：”或字母P、Q，第20键位用于输入字母D。第6键位、第16键位用于输入字母K、J，第26键位、第27键位用于输入字母P、Q或字母Z、符号“；：”。第1键位、第11键位用于输入字母B、C，第5键位、第15键位用于输入字母X、Y，第21键位、第22键位用于输入字母V、W。第23键位、第24键位、第25键位依次用于输入字母M、F、L。
附图说明
图1为一个实施例的连续字母键盘的字母键区的键位的结构示意图；
图2为最佳实施例所示的连续字母键盘的键位的结构示意图；
图3为图2所示的连续字母键盘另一个实施例的键位的结构示意图；
图4为图2所示的连续字母键盘再一个实施例的键位的结构示意图。
具体实施方式
为使本发明的目的、技术方案及优点更加清楚，以下结合附图及具体实施方式，对本发明进行进一步的详细说明。本文所使用的术语“垂直的”、“水平的”、“左侧”、“右侧”、“上侧”、“下侧”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
如图1所示，在一个实施例中，提供了一种连续字母键盘。使用该连续字母键盘时，左手的食指、中指、无名指、小指分别放在第14、第13、第12、第11键位，右手的食指、中指、无名指、小指分别放在第17、第18、第19、第20键位。其中，左手的食指击打第4列、第5列键位，中指击打第3列键位，无名指击打第2列键位，小指击打第1列键位。右手的食指击打第7列、第6列键位，中指击打第8列键位，无名指击打第9列键位，小指击打第10列键位。
由于手指的伸展比收缩容易，所以按照击键的难易程度，依次为第2行、第1行、第3行。
左手和右手中，中指、食指、无名指击键的速度依次降低，击键的难度也依次提高。小指击键的速度远远低于中指、食指和无名指，小指击键的难度高于中指、食指和无名指。因此按照击键难易程度，第2行中最易击打的键位中，左侧键区依次为第13、第14、第12键位；右侧键区依次为第18、第17、第19键位。按照击键难易程度，第1行中次易击打的键位中，左侧键区依次为第3、第4、第2键位；右侧键区依次为第8、第7、第9键位。
小指最细最短，伸展及收缩最慢，所以第1列的第21、第1键位、第10列的第30、第10键位最难击打。食指较短，从第14键位伸展到第5键位、从第17键位伸展到第6键位的距离较远，所以较难击打的键位为第5、第6键位。
手指击键特点：打字时，双手协调交替击键和单手换指同行击键速度最快， 单手换指换行次之，单手同指最慢。单手换指同行，即击打同侧同行不同列(第1列-第4列或第7列-第10列)的键位时，手掌不动手指交替击打。
第11键位适合设为能够和第12、第13、第14键位形成常用字母对的字母。第20键位适合设为能够和第17、第18、第19键位形成常用字母对的字母。第11、20键位在第2行，小指无需伸缩就可以击打，是易击打的键位。

第一步，设置高频字母的键位。辅音设在左侧键区，元音设在右侧键区。
6个高频辅音字母中，连续字母为RST，单个字母为G、H、N。G在汉语拼音中是高频字母，和N形成韵母ang、eng、ing、ong；在英文中和N形成常用字母对ng，所以G和N应该设在同一行。R、S、T形成连续字母RST，所以R、S、T应该设在同一行。R、S、T在汉语拼音中是中频字母，适合设在次易击打的键位。因此将G、H、N设在左侧键区最易击打的第2行，将R、S、T设在左侧键区次易击打的第1行。
5个元音中，ou在英文中是常用字母对，在汉语拼音中是韵母，所以O和U应该设在同一行。U在英文中是中频字母，适合设在次易击打的键位。所以将元音字母A、E、I设在右侧键区最易击打的第2行，将O、U设在右侧键区次易击打的第1行。
汉语拼音和英文高频字母表
类别 辅音 元音
英文 H N R S T A E I O
汉语拼音 G H N A E I O U
根据汉语拼音和英文的频率及常用字母对特点，如图2至图4所示，在最佳实施例中，将最易击打的第12、第13、第14键位设为H、N、G；次易击打 的第2、第3、第4键位设为R、S、T。将最易击打的第17、第18、第19键位设为E、I、A；将次易击打的第7、第8键位设为U、O。
第2、第3、第4键位形成连续字母RST，符合一般人从左至右的阅读习惯。
汉语拼音和英文的高频字母频率表
字母 英文 汉语拼音 合计 字母 英文 汉语拼音 合计
n 6.0％ 13.0％ 19.0％ i 7.6％ 13.5％ 21.1％
h 6.0％ 7.5％ 13.5％ e 12.2％ 6.3％ 18.5％
t 9.8％ 1.1％ 10.9％ a 7.5％ 9.8％ 17.3％
g 2.3％ 8.4％ 10.7％ o 7.9％ 5.7％ 13.6％
s 6.7％ 2.4％ 9.1％ u 2.8％ 8.1％ 10.9％
r 6.7％ 0.8％ 7.5％        
N的合计频率在辅音中最高，设在最易击打的第13键位。在汉语拼音中sh是常用声母，在英文中th是常用字母对。为了避免单手同指连续击打sh或th，H不能和S、T设在同一列。将第12键位设为H，第14键位设为G。
I的合计频率在元音中最高，设在最易击打的第18键位。E的合计频率在元音中次高，设在最易击打的第17键位。第19键位设为A。
O的合计频率大于U，所以将次易击打的第8键位设为O。第7键位设为U。
在其它实施例中，也可将第12、第13、第14键位设为G、N、H或G、H、N，第2、第3、第4键位设为T、S、R或R、T、S，第17、第18、第19键位设为I、E、A或A、I、E。
第一步布局
Figure PCTCN2020116546-appb-000002
第二步，设置右侧键区的字母。右侧键区共有15个键位，元音字母用了5个，符号预留4个，还有6个空位。需要将6个辅音字母设在右侧键区。
Z在英文中频率最低，没有常用字母对，设在右侧键区不影响英文打字。Z 在汉语拼音中是频率最高的中频字母，和H形成声母zh。声母zh的频率是声母z的约2倍。将Z设在右侧键位便于双手交替击打zh，有利于提高汉语拼音打字速度。符号的使用频率较低，不能设在易击打的键位。在最佳实施例中，将次易击打的第9键位设为Z，难击打的第10键位设为符号“；：”。在其它实施例中，也可将第9、第10键位用于输入字母P、Q。第8、第9、第10键位形成连续字母OPQ。
其中，键位用于输入符号“；：”，是指该键位既可用于输入符号“；”，也可用于输入符号“：”，其切换方式与现有键盘相同。本文其它用于输入符号的键位，使用方法与之类似。
D在汉语拼音和英文中是合计频率最高的中频字母，设在右侧键区有利于增加右侧键区键位的总频率，避免左右侧键位的总频率相差过大。D在英文中有常用字母对nd、da、ed。将易击打的第20键位设为D，便于双手交替击打nd，右手换指击打da、ed。
辅音字母J、K、P、Q在英文中与元音形成的字母对很少。将第6、第16键位设为K、J。K在汉语拼音和英文中是低频字母，设在难击打的第6键位。J在汉语拼音中是中频字母，设在第16键位，和K形成连续字母JK。在最佳实施例中，将第26、第27键位设为P、Q，形成连续字母PQ。在其它实施例中，也可将第26、第27键位设为Z、符号“；：”。
第28、第29、第30键位设为符号“,<”、“.>”、“/？”，与QWERTY键盘兼容。
第二步布局

第三步，设置左侧键区的字母。剩余的字母有BC、F、LM、VW、XY。
C在汉语拼音中和H形成声母ch，在英文中和H、N形成字母对hc、nc，所以C应该和H、N设在同一行。因此将第11键位设为C。B在汉语拼音和英文中为低频字母。将难击打的第1键位设为B，和C形成连续字母BC。
V在汉语拼音和英文中是低频字母，将难击打的第21键位设为V。将第22键位设为W，和V形成连续字母VW。
X在汉语拼音中是中频字母，在英文中是低频字母，将难击打的第5键位设为X。将第15键位设为Y，和X形成连续字母XY。
将第23、第24、第25键位设为M、F、L。M和N形成连续字母MN，F和G形成连续字母FG。
第三步布局
Figure PCTCN2020116546-appb-000004
本发明最佳实施例键盘具有BC、FG、JK、MN、PQ、RST、VW、XY共17个连续字母。右侧键区形成汉语拼音uoz“周(zou)”、英文缩写EIA。整体排列有序，适合汉语拼音和英文快速输入，适应信息时代使用需求。
本发明最佳实施例的左右侧字母频率比，英文为55.7％：44.3％，汉语拼音为45％：55％。经过测试，汉语拼音和英文打字速度，比QWERTY布局提高约50％。另外，还可以提高德语、法语、西班牙等语言的打字速度。
最佳实施例键盘的字母排列，受到汉语拼音和英文的频率、键位击打难易程度、是否连续字母约束，并不能随意设置。调整任何一个字母位置，都可能会降低汉语拼音和英文打字速度，减少连续字母数量，破坏整体布局。
