为了便于分辨双键和弦键位，在上下两层双键和弦键位标识之间，设置键位指示图形，利用该图形斜边指向与单键标识相差最远的行的双键和弦键位标识及另一列参与该组合双键和弦键位的单键键位标识，具体地说，在按键2(222)与5(225)、按键5(225)与8(228)的单键键位标识之间，分别设置一个跨过上下两层分隔线并与所述单键键位标识垂直对齐的键位指示图形(222A和228A)，其上方的2个斜边分别指向按键7、9的单键键位标识，其下方的2个斜边分别指向按键1、3的单键键位标识，用于指示中列按键与边列按键之间的双键和弦键位差别最大的上下组合,如图5所示，处在顶层中列按键o(222)与中层中列按键h(225)之间的键位指示图形(222A)，其非水平方向的四个斜边分别指向所述键盘四角的按键t(221)、r(223)、a(227)、n(229)，其中，处在分隔线(2225)之上的两个上斜边由按键o(222)分别指向a(227)、n(229)，分别指示按键o(222)与其双键组合j(2227)、q(2229)的和弦键位，如斜边(222A9)用于指示q(2229)的和弦键位是由按键o(222)与n(229)组合而成的，处在按键h(225)与按键i(228)之间的键位指示图形(228A)，其非水平方向的四个斜边分别指向所述键盘四角的按键t(221)、r(223)、a(227)、n(229)，其中，处在分隔线(2225)之上的两个上斜边由按键i(225)分别指向a(227)、n(229)，分别指示按键i(222)与其双键组合j(2257)、k(2259)的和弦键位，如斜边(228A9)用于指示k(2259)的和弦键位是由按键h(225)与n(229)组合而成的,如此，以分隔线(2225)和(2258)为界，两个键位指示图形222A的上半部分和228A的下半部分的斜边分别用于指示中列按键o(222)和i(228)与左右列按键组合的双键和弦键位，键位指示图形222A的下半部分和228A的上半部分的斜边用于指示中列按键h(225)与左右列按键组合的双键和弦键位, 更确切地说，用于指示差距最大的层之间的单键组合的双键和弦键位标识的位置；在按键1与3、按键3与7的单键键位标识之间的右侧，分别设置一个键位指示图形(221A和227A)，其上方的斜边指向按键9的单键键位标识，其下方的斜边指向按键3的单键键位标识，用于指示边列按键之间的双键和弦键位差别最大的上下组合，如此，以分隔线(2225)和(2258)为界，两个键位指示图形221A的上半部分和227A的下半部分的斜边分别用于指示左列按键t(221)和a(227)与右列按键组合的双键和弦键位，两个键位指示图形221A的下半部分和227A的上半部分的斜边用于指示左列按键e(224)与右列按键组合的双键和弦键位,更确切地说，用于指示差距最大的层之间的单键组合的双键和弦键位标识的位置,如斜边(221A9)用于指示删除键(2219)的和弦键位是由按键t(221)与n(229)组合而成的,斜边(227A9)用于指示Ins键(2249)的和弦键位是由按键e(224)与n(229)组合而成的。此法给出差距最大的层双键和弦键位的方向，由此，配合同层单键的双键和弦键位与两个同层单键键位标识水平对齐，提示了各组双键和弦键位的指法，以便于操作。
完成双键和弦键位标识设置后，再设置所述屏幕图像显示中三键和弦键位标识，按位置在所述九宫格键盘的中列按键与右列按键各选一键，用连线将选中两个按键位置所在的点连为一体，形成一个图形符号，再用所述图形符号与左列按键147进行组合，依据各按键在所述九宫格键盘的位置，在所述图形符号的左侧对应的左列按键的位置自上而下放置所述组合的三键和弦键位功能标识名称，从而形成一组三键和弦键位标识；按照三键和弦键位标识中的中列按键所在的上下位置将各组三键和弦键位标识设置在用两条分隔线分隔为三层的一个矩形图框内，每层具有中列按键与右列三个按键组合而成的图形符号下的三组三键和弦键位标识。如图6所示，按键2分别与右列按键369组成的所述3个图形符号(2323)、(2326)、(2329)，是按键2分别与右列按键3、按键6、按键9连接而成的图形符号，每个所述图形符号左边自上而下排列的3个和弦键位功能标识名称，分别表示该键位是所述图形符号所代表的双键和弦键位与左列按键147组合而成的键位，如三键和弦键位Ctrl(23234)，是按键2与按键3组成的所述图形符号(2323)与按键4的组合键位，因此三键和弦键位Ctrl(23234)就是按键2、按键3与按键4三个按键组合而成的和弦键位；同样，中层是按键5分别与右列按键639 的所述3个图形符号(2356)、(2353)、(2359)，左边添加代表左列按键147组合的3个和弦键位功能标识名称，下层是按键8分别与右列按键963的所述3个图形符号(2380)、(2386)、(2383)，左边添加代表与左列按键147组合的3个和弦键位功能标识名称，如三键和弦键位-聊天(23864)是图形符号(2386)与按键4的组合键位，因此三键和弦键位聊天(23864)就是按键8、按键6与按键4三个按键组合而成的和弦键位；用两条分隔线(232C和235C)将上下各层隔开。
进一步地，所述标明中列按键与右列按键方位的图形符号中，代表中列按键的部分尺寸较大，代表右列按键的部分尺寸较小。如图7B的下部是放大的23图像所示，所述上层图形符号(2323)(2326)(2329)左部代表中列按键2的部分尺寸较大，右部代表右列按键369的部分尺寸较小，同样地，中层图形符号(2353)(2356)(2359)，下层图形符号(2389)(2386)(2383)左部对应中列按键5、8的部分尺寸较大，右部代表右列按键369的部分尺寸较小；如此突出显示所述图形符号中中列按键的位置，更加方便分辨各个键位。
将所述具有单键和双键和弦键位标识的显示图像与所述具有三键和弦键位标识的显示图像横向或纵向排列在一起，上方添加一条信息栏，显示在所述屏幕上。合并为一个包含单键、双键和弦与三键和弦键位标识的完整显示图像体系。如图7所示，是手机的屏幕2上所显示的和弦键位标识的显示图像，如图7A所示，手机的屏幕2下部横向排列显示所述图像，其中，左下部为单键和双键和弦键位标识的显示图像22，右下部为三键和弦键位标识的显示图像23，两者上方的横条为信息栏21，信息栏21中文字en表明所述图像处在英文输入状态；如图7B所示，手机的屏幕2左部纵向排列显示所述图像，其中，中间位置为单键和双键和弦键位标识的显示图像22，其上方的横条为信息栏21，其下方为三键和弦键位标识的显示图像23，信息栏21中文字en-A表明所述图像处在大写英文字母输入状态。
这样，所述显示图像对应包含了所述键盘三键并击以内所有的键位：显示图像22中的9个单键标识，27个双键和弦键位标识和显示图像23中的27个三键和弦键位标识，合计9+27+27＝63个键位，加之按压按键0时可更换此63个键位的赋值，就可实现多达63X2＝126个键位，就是由仅为信用卡大小、10个按键的 所述键盘通过多键并击的操作实现的，而且完全不用背记这些键位，只需短时间学会键位规则，然后通过观察动态显示在屏幕上的键位操作指法提示，单键、双键和弦键位标识和三键和弦键位标识分别对应所述键盘的单键或双键、三键并击，或者按压按键0时九宫格内的按键单键或双键、三键并击，盲打此和弦键盘即可操作。
在英文字母输入场景下，设置单键字母与所述键盘按键编号的对应关系为t-1、o-2、r-3、e-4、h-5、s-6、a-7、i-8、n-9、空格-0，按键0也是Shift键，按压的同时再按压字母键位可输入相应的大写字母；设置双键和弦键位字母及功能为d-21、p-23、c-24、b-26、j-27、q-29、m-51、w-53、u-54、f-56、y-57、k-59、z-83、x-84、v-86、g-87、l-89、(，/.大写时)-81具有中列按键的双键和弦键位；将Enter、Backspace、Delete、Insert等双键和弦功能键位设置在边列双键和弦键位上。如图5所示，按键(编号)与字母键位(编号)的对应关系为按键1(101)-t(221)、按键2(102)-o(222)、按键3(103)-r(223)、按键4(104)-e(224)、按键5(105)-h(225)、按键6(106)-s(226)、按键7(107)-a(227)、按键8(108)-i(228)、按键9(109)-n(229)、按键0(100)-空格(未标注)；按键0也是Shift键，按压的同时再按压字母键位可输入相应的大写字母；将具有中列按键的双键和弦键位设置为字母及符号，其和弦键位(编号)与字母键位(编号)的对应关系为21-d(2221)、23-p(2223)、24-c(2224)、26-b(2226)、27-j(2227)、29-q(2229)、51-m(2251)、53-w(2253)、54-u(2254)、56-f(2256)、57-y(2257)、59-k(2259)、83-z(2283)、84-x(2284)、86-v(2286)、87-g(2287)、89-l(2289)、81-(,/.大写时)(2281)；将Enter、Backspace、Delete、Insert等双键和弦功能键位设置在边列双键和弦键位上，如图5所示，边列双键和弦键位79-Enter(2279)、19-Backspace(2219)、13-Delete(2273)、49-Insert(2249)。
进一步地，在所述九宫格键盘的左右两边均设置一个数字为0的按键，构成兼顾右左单手和弦键盘。如图2所示，在所述九宫格键盘下方左右两边均设置一个数字为0的按键(100B)和(100C)，其中，数字为0的按键(100B)与所述九宫格键盘可构成一个右手和弦键盘，数字为0的按键(100C)与所述九宫格键盘可构成一个左手和弦键盘，从而成为一个兼顾左右单手的和弦键盘。
实施例二，为满足部分用户的操作习惯，在赋值为数字1-9九宫格键盘下方靠近按键0的区域，设置若干辅助功能键，和或，在按键9或7的下方设置一个辅助功能键，这些辅助功能键包括但不限于Shift、符号(Sym)、Ctrl、Alt、Fn、数字等。
如图3所示，九宫格键盘下方靠近按键0的区域，设置若干辅助功能键，分为两种情况，其一，在1A区域内，设置100A位置为一个按键0，再在所述按键0的内测设置设置若干辅助功能键，和或，在按键9的下方1B设置一个辅助功能键；其二，在1A区域内，设置100B位置为一个按键0，再在所述按键0的左右两测设置设置若干辅助功能键，和或，在按键9的下方1B设置一个辅助功能键；
具体的方式为，所述按键0(100)处在所述九宫格键盘左(右)列按键下方，功能辅助键Aa(10A)和123(10B)纵向排列处在所述按键0(100)外侧，辅助功能键Ctrl和Sym纵向排列处在所述按键0(100)内侧，辅助功能键Alt处在功能辅助键Ctrl和Sym的内侧，辅助功能键Fn处在所述九宫格键盘右(左)列按键下方，构成右(左)手单手和弦键盘。如图4所示，所述按键0(100)处在所述九宫格键盘左列按键下方，功能辅助键Aa(10A)和123(10B)纵向排列处在所述按键0(100)外侧，辅助功能键Ctrl和Sym纵向排列处在所述按键0(100)内侧，辅助功能键Alt处在功能辅助键Ctrl和Sym的内侧，辅助功能键Fn(10F)处在所述九宫格键盘右列按键下方。其操作方式与现有键盘相同，按压所述功能辅助键不松开，所述键盘就会提供相应的键位，如功能辅助键Aa(10A)-大写、123(10B)-数字、Ctrl-快捷键和Sym-符号等，按照屏幕键位提示即可输入，然后松开所述功能辅助键，所述键盘返回到原有的状态。
而在实施例一中，可将CapsLock、NumLock、符号(Sym)、Ctrl、Alt、Fn、数字等功能转换键位设置在边列双键和弦键位和或三键和弦键位上。按压所述按键0旁边实体功能辅助键不松开进行操作不同，输入和弦键位上的功能转换键位后，所述键盘就一次性提供相应的键位，操作一次后自动返回原态，或者，所述键盘进入转换后的状态进行操作，按压“返回”键位或再次按压原键位后，才能返回原态，此操作与现有键盘的CapsLock、NumLock作用相同；如此，替代直接设置的辅助功能键，仅用10个按键就可实现相应的变换。如图5所示，边列和弦键位Aa(2276)就是转换英文大小写的功能键，如图6所示，功能转换和 弦键位有符号(23231)、Ctrl(23234)、Alt(23264)、数字(23564)、中/en(23897)等三键和弦键位。
实施例三，本实施例采用如图2所示，采用包括所述九宫格键盘及左(右)边外侧偏下位置(100A)的按键0所构成的右(左)手单手和弦键盘，通过无线与手机或PC连接并可向所述设备发送被按压键位的编码。所述键盘可实现根据所述设备的应用场景，动态对所述和弦键盘的键位进行相应的赋值，所述赋值的键位也动态联动地显示在所述屏幕上，所述按键赋值的对象，包括但不限于字母、符号、数字、表情、密码、文件、文件夹、文件传送、搜索、网购、视频、音频、定位、导航、红包、图像、名片、扫码、时间、日程、应用程序、命令菜单、支付、网址、设置、切换等。无论手机、平板电脑、PC等设备，都会频繁地切换其应用程序或场景，本发明的方法突破了原有键盘单一而固定的字母型如文字、快捷键、拼音的输入的束缚，所述键盘的键位与对应屏幕显示的键位标识是动态可变的，即根据所述设备的应用场景，动态对所述和弦键盘的键位进行相应的赋值，所述赋值的键位也动态联动地显示在所述屏幕上，所述按键赋值的对象，包括但不限于字母、符号、数字、表情、密码、数据库、文件、文件夹、文件传送、搜索、网购、视频、音频、定位、导航、红包、图像、名片、扫码、时间、日程、应用程序、命令菜单、支付、网址、设置、切换等，如图5所示，英文字母或中文拼音输入状态，如图8所示，是所述键盘映射手机桌面的和弦键位的状态。
当按压所述键盘的按键使所述设备进入新的场景和或应用程序时，所述键盘按键的赋值及其键位标识显示自动转换相应的功能和或字符和或命令。如图8所示，是手机开机时，所述键盘映射桌面的和弦键位的状态，如相机(222)、视频(224)、聊天(225)等单键标识，地图(2221)、翻译(2224)、天气(2227)、支付(2253)、办公(2256)、绘图(2259)等双键和弦键位；如图9A所示，是所述设备打开Excel时，所述键盘映射Excel命令菜单的和弦键位的状态。
需要补充的是，双键和弦键位标识的显示图像可凭借第n层的单键标识与所在层第n行的双键和弦键位标识水平对齐，其中，n≤3；一个双键和弦键位标识处在参与此双键组合的两个按键的单键标识之间的连线上，不需要权利7中的键位指示图形，也能够给与很好地键位指法提示，如图8所示，显示图像中没有键位指示图形，辅助线221B6由图库(221)穿过和弦键位-中/en(2216)指向日历 (226)，表明一个双键和弦键位标识处在参与此双键组合的两个按键的单键标识之间的连线上，同样的，和弦键位-返回(2219)处在此双键组合的两个按键的单键标识之间图库(221)与更多(229)的连线-辅助线221B6上；再如，和弦键位浏览(2286)和搜索(2283)分别处在由游戏(228)与日历(226)和音乐(223)两个按键的单键标识之间的连线上，即辅助线228B6和228B3。
无论绘图、办公等软件或场景，在某些对象被选择后，其所需的命令范围会缩小并具更强的针对性，当所述设备显示界面的某些对象被鼠标或其他方式选择后，对应的命令或功能会调取到所述键盘的键位上。如图10A所示，是所述设备在运行Excel时，用鼠标选中25区域内的若干单元格，图10B所示，针对被选中的单元格的相应的命令就会调取到所述键盘的键位上，替代如图9A所示的Excel的菜单命令，以减少搜索命令的时间而提升效率。
文件管理中的多级目录结构，命令菜单多级命令等，都采用以分支关系定义的层次结构的树形数据，所述键盘的键位可呈现树形数据并进行相应的查找，可将处在单键键位的上一级对象旁边的双键和弦键位设置为其下一级对象。如图11A所示，键位图像中的A(221)、B(222)、C(223)及E、F、G、H等单键标识为具有下级对象的文件夹和或菜单，More(229)可打开更多的同级对象，单键标识A(221)旁边的和弦键位A1(2213)、A2(2216)、A3(2219)则为A(221)的下一级对象，同样，单键标识E(225)旁边的和弦键位E1(2253)、E2(2256)、E3(2259)则为E(225)的下一级对象，可避开上级文件夹而直接选取下一级对象；如图11B所示，是图11A按压B(222)后，进入下一级目录的状态，同样，单键标识B8(225)旁边的和弦键位B81(2253)、B82(2256)、B83(2259)则为B8(225)的下一级对象。又如图9A所示，是Excel命令菜单，其中审阅(221)、开始(222)、公式(223)、视图(224)、插入(225)、数据(226)、帮助(227)、页面布局(228)、格式(229)单键标识为一级菜单命令，中列与右列单键标识左边的双键和弦键位为此单键标识下一级命令，如字体(2221)、对齐(2224)、数字(2227)为开始(222)的下一级命令，样式格式(2283)、字样式(2286)、排列(2289)为格式(229)的下一级命令，新建(2213)、另存(2243)、关闭(2279)等常用命令则设置在边键双键和弦键位上；如图9B所示，是图9A所示的状态按压按键2后所进入的开始(222)命令菜单，其中剪切板(221)、字 体(222)、对齐(223)、数字(225)、样式(226)、单元格(228)、编辑(229)等单键标识为第二级菜单命令，中列与右列单键标识左边的双键和弦键位为此单键标识下一级命令，如字体(2221)、对齐(2224)、数字(2227)为开始(222)的下一级命令，样式格式(2283)、字样式(2286)、排列(2289)等双键和弦键位为格式(229)的下一级命令；所述键盘查找能力十分强悍，以其63个键位为例，3次查找竟可达到25万之多，63X63X63＝250047。
将所述按键0设置为各场景下最必要的功能转换键，包括但不限于字母输入状态下为Shift键，按压后将小写转为大写字母；查找状态下为选定键，按压后将打开对象转为选定对象；汉字输入状态下为数字键，按压后将文字输入转为文字选定，等等。如图7A所示，是英文小写输入状态，而图7B所示,是按压所述按键0后，英文小写转为大写字母的状态；如图11A与B所示，图B是图A状态下按压键位B(222)而打开的下一级文件，此时按压按键0不松再按压B4(221)，则文件夹B4就被选定而不是打开，就会将针对文件夹的命令调取到所述键盘，类似图10B的状态，将复制、剪切、删除、转移、发送、重命名、压缩、共享等针对文件夹操作的命令设置在相应的键位上。
随着所述设备所处的场景或状态不同，所述显示图像22、23和信息栏21及其中的文字或符号的颜色和或底色也不同。如图5与图9A对比，其单键标识的字体和底色都不同，图5的单键标识t(221)、o(222)是白底黑字，而图9A的的单键标识审阅(221)、开始(222)是黑底白字。
虽然已经参照其特定优选实施方式示出和描述了本发明的，但是本领域的普通技术人员应该理解，在不偏离所附权利要求所限定的本发明的精神和范围的情况下，可以在形式和细节上进行各种变化。
