For example, if En1 and Shift are marked as pressed by the keyboard firmware (in this case, En1, Shift and other side keys are pressed), then if En2 is operated, the keyboard firmware will be pressed at the mark En2. At the same time, the markers En1 and Shift are released (although the fingers of En1 and Shift are not released). For another example, if only En1 is marked as pressed, if Shift is operated next, the keyboard firmware only marks Shift, so that the side key combination En1+Shift can be implemented.

Description

一种实现多个位置动态被动确定按键之方法 技术领域
本发明涉及一种在多点触控板/触摸屏上实现多个位置动态被动确定按键的方法。
背景技术
公布号为WO 2014/023118 A1的PCT申请，披露了触控板可以用作手持数字设备键盘的侧键，但没有详细披露具体的实现方法。
发明内容
当用户的一只或者两只手的若干手指握持或者触按到多点触控板/触摸屏上时会生成若干触按点。在本发明中，通过把触按点当作按键，并把手指通过触按点和按键一一对应起来，把触按点及其坐标因相应手指的操作失而复得或者把触按点的坐标中代表手指压力值的坐标之值因相应手指的操作发生改变当作对对应按键的操作，就可以在多点触控板/触摸屏上实现多个位置动态被动确定的按键。在按键操作结束之后，上述手指依然是握持或者触按在上述触控板/触摸屏上的。
采用多点触控板/触摸屏做若干按键，不仅不需要像操作位置固定的按键那样在操作前先要把各个手指对准各个按键，而且也不用顾忌在操作中会按错按键，因为一个手指会永远按到正确的按键上，原因就在于一个按键的位置是在相应的手指按下后才确定的。在以下的部分叙述中，在多点触控板/触摸屏上设置的侧键就是上述的按键。

具体实施方式
一、图1为一种手机1，2*4阵列的实体键盘2设在其下部，侧键Shift和2Hands设在其左侧面，侧键En1、En2、Num和Punc设在其右侧面多点触控板4上。在手机1的触摸显示屏上设有键盘动态映射区10。根据当前操作的侧键和侧键组合，映射区10动态显示图7到图14的键盘布局，以提示用户在键盘2上操作。映射区10本身也可以是一触摸键盘。侧键指示器6用于指示当前操作的侧键或侧键组合。按钮7用于关闭或打开映射区10。5是映射区10关闭时的情形。
用户左手的5个手指在握持手机1时，左手的拇指握持在Shift键上，左手的食指、中指、无名指和小指握持在触控板 4上，手指在触控板4上的触按点即是侧键，2Hands由左手拇指根部的突起自然靠压。左手握持手机1和侧键并操作侧键，右手操作键盘2。左手的食指对应En1，其它类推。En1和En2用来输入26个英文字母，Num主要用来输入数字，Punc主要用来输入标点符号，Shift键的作用同于PC键盘上的Shift键。
侧键采用先释放与欲按侧键对应的手指，马上再按回去的方法进行操作，当手指重新按回去后，对应的侧键就被按下了。在一个侧键被按下后，键盘固件根据接下来其它侧键的操作决定其是否被“释放”。例如，在En1和Shift被键盘固件标记为按下(此时En1、Shift和其他侧键都是被按着的)的情况下，接下来如果En2被操作，键盘固件将在标记En2按下的同时标记En1和Shift释放(尽管按着En1和Shift的手指并没有释放)。又比如，在只有En1标记为按下的情况下，如果接下来Shift被操作，则键盘固件仅标记Shift按下，这样就可以实现侧键组合En1+Shift。其它类推。
2Hands键被触按将触发键盘固件检测Shift键是否被触按以及是否在触控板4上形成四个触按点。如果是则表明手机1、Shift和触控板4被正确握持，键盘固件参照坐标系8把这四个触按点按x值从大到小(即从上到下)排序，并把排序后的触按点保存为pIndex，pMiddle，pRing和pLittle，然后计算这些排序后的触按点中相邻两个点之间沿x轴间距的平均值avg并保存起来，接着把pIndex，pMiddle，pRing和pLittle分别与左手的食指、中指、无名指和小指以及触控板4上的侧键En1、En2、Num和Punc一一对应起来，并标记左手的食指、中指、无名指和小指为按下。
键盘固件接着激活侧键，并默认当前按下的侧键是En1,即键盘固件标记En1按下，标记其他侧键为释放，尽管此时所有的侧键都被左手的五个手指触按着。
在侧键激活之后，如果触控板4上触按点的个数发生了变化：(a)触按点少于3个多于0个，则说明触控板4上的多个手指同时操作，为简单起见，这种情形不在下面描述；(b)触按点等于0个，则说明触控板4上的手指全部释放，键盘固件去激活侧键，并重新等待侧键激活条件的出现；(c)触按点等于3个，则说明触控板4上只有一个手指释放了，在操作某个侧键。键盘固件把检测到的三个触按点按x值从大到小排序，得到三个点p31，p32，p33。
(一)如果p31.x<＝pMiddle.x+avg*50％(avg也可以用20mm来代替，以克服用户的手指在触控板4上的握持手势过于随意，avg不准的情况。20mm是各种人种成人手指宽度的平均值，是一个经验值。avg还可以在用户初次使用手机时经过校验确定)，则说明左手的食指释放了，食指在触控板4上的触按点及其坐标失去，键盘标记左手食指释放。如果为否，则继续第(二)步。
(二)如果p33.x>pRing.x-avg*50％,则说明左手的小指释放了，小指在触控板4上的触按点及其坐标失去，键盘标记左手小指释放。如果为否，则继续第(三)步。
(三)如果pMiddle.x-avg*50％<p32.x<＝pMiddle.x+avg*50％，说明左手的无名指释放了，键盘固件标记左手无名指释放，否则说明左手中指释放了，键盘固件标记左手中指释放。
如果其后，键盘固件检测到在触控板4上重新生成了四个触按点，则说明刚才释放的手指又按回去了，对应该手指的触按点及其坐标失而复得，键盘固件重新标记该手指按下，同时标记与该手指对应的侧键按下，并同时决定是否对以前标记为按下的侧键重新标记为释放。接着，键盘固件把重新检测到的四个触按点按x值从大到小排序，得到p41，p42，p43和p44，并用它们分别更新pIndex，pMiddle，pRing和pLittle。之后，键盘固件如上述不断循环检测与处理。
由于触控板4上各个侧键的初始位置是由用户的各个手指在触控板4上触按点的初始位置确定的，不是预先就确定的，而且这些侧键的位置在操作过程中还会随着这些触按点位置的不断变化而变化。因此采用多点触控板做若干侧键，不仅不需要像操作位置固定的侧键那样在操作前先要把各个手指对准各个侧键，而且也不用顾忌在操作中会按错侧键，因为这些手指会永远按到正确的侧键上，原因就在于一个侧键的位置是在相应的手指按下后才确定的。
当左手的各个手指双击时，侧键布局如图5和图6所示。其中，Home用作主页键；Recent用于显示最近打开的应用；Back，Forward用于导航；cMenu是context menu的缩写，用于打开和关闭当前应用的菜单(工具栏)。
在触控板4上用左手食指向上滑动根据手机1当前应用的不同或增加音量或者向上翻页，用左手食指向下滑动根据手机1当前应用的不同或减小音量或向下翻页。
图7为手机1侧键En1对应的键盘布局，中间两行键11对应键盘2的两行键，标记②12表示其所在行的每一个键是由键盘2上对应两键同时按下和释放实现。比如，i键是由对应的a和b键同时按下和释放实现。标记④13表示其所在行的每一个键是由键盘2上对应的四个键同时按下和释放实现。如，BS键是由a、b、c和d四个键同时按下和释放实现。其余键和其余键盘布局的情形类推可得。图7到图14键盘布局所对应的侧键或侧键组合标示在各个布局的左上角。
图15也是一种手机14，在其左侧如图16设有侧键cMenu和2Hands，在其右侧如图17和背部中间如图18的多点触控板上设有侧键Back，Forward,Recent和Home。
在手机14的背部设置触控板，便于用户单手(左手或右手)握持并操作手机，在这种情形下，缺失的cMenu键，可以通过食指在背部触控板上双击实现。当握持手机14手的手指在背部触控板上操作时，该手的拇指会触按到正面的触摸显示屏上，这种与背部触控板上的操作同时发生的触摸动作应该被忽略。键盘固件在检测到背部触控板上生成四个触按点时，激活触控板上的侧键。
[根据细则91更正 05.03.2016]　
二、图19和图20是一种曲面屏手机16，其曲面屏是一块多点触摸屏。在曲面屏的左边设有侧键Shift和2Hands，在曲面屏的右边设有侧键Rmt、Ctrl、En1、En2、Num、Punc和Alt。手机16和侧键由左手握持并操作，Ctrl和Rmt由左手食指向上位移操作，Alt由左手小指向下位移操作(如果是左撇子使用手机16，则曲面屏左右两侧的侧键布局互换即可)。键盘17为设在曲面屏上的4*4矩阵触摸键盘，其布局会根据当前操作的侧键或侧键组合动态改变。图21到图30为手机16的侧键或侧键组合对应的键盘布局。
当左手握持手机16时，左手拇指握在曲面屏的左侧，左手的其余四指均匀地握在曲面屏的右侧。当手机16检测到在曲面屏的两侧生成6个触按点时，把右侧四个触按点参照坐标系20按x值从大到小排序，并计算这些排序后的触按点中相邻两个点之间沿x轴的间距dist以及这些间距的平均值avg和总和ttl并把它们保存起来。如果每一个dist都在avg*(1±25％)的范围内，且ttl在wdth*3*(1±20％)的范围内(wdth表示用户手指的平均宽度，预定为20mm，可以在用户初次使用手机时经过校验为其确定一个新值)，则手机16接着检测第一个触按点到曲面屏顶边的垂直距离是否大于2.5*avg，第四个触按点到曲面屏底边的垂直距离是否大于1.5*avg。如果是，则手机16激活侧键。
接下来，手机16保存上述排序后的四个触按点为pIndex，pMiddle，pRing和pLittle，并把它们分别与左手的食指、中指、无名指和小指以及曲面屏右侧的En1、En2、Num和Punc一一对应起来，并标记左手的食指、中指、无名指和小指为按下。与此同时，对于曲面屏左侧生成的两个触按点，手机16把上面的触按点与左手拇指和Shift对应起来，把下面的触按点与2Hands对应起来。接着，手机16默认标记En1按下，标记其他侧键释放(2Hands除外)。
对于Shift、En1、En2、Num和Punc采用先释放与欲按侧键对应的手指，马上再按回去的方法进行操作。在侧键激活之后，如果手机16检测到曲面屏右侧只有3个触按点(其它数量触按点的情形参照第一部分的描述)，则说明曲面屏右侧有一个手指释放了，在操作某个侧键。手机16把检测到的三个触按点按x值从大到小排序，得到三个点p31，p32，p33。
(一)如果p31.x<＝pMiddle.x+avg*50％，则说明左手的食指释放了，左手食指在曲面屏右侧的触按点及其坐标失去，手机16标记左手食指释放。如果其后，手机16检测到在曲面屏右侧重新生成了4个触按点，则说明左手的食指又按回去了，左手食指在曲面屏右侧的触按点及其坐标失而复得，手机16重新标记左手食指按下。与此同时，手机16把曲面屏右侧重新生成的四个触按点按x值从大到小排序，得到p41，p42，p43和p44。
如果pMiddle.x+avg*50％<p41.x<＝pMiddle.x+avg*150％，则说明左手食指按在了En1的位置，手机16标记En1按下，标记其他侧键除Alt外为释放。也就是En1被按下后，可能对应的侧键和侧键组合是：En1或者Alt+En1(如果此前Alt已经标记为按下的话)；
如果pMiddle.x+avg*150％<p41.x<＝pMiddle.x+avg*250％，则说明左手食指按在了Ctrl的位置，手机16标记Ctrl和En1按下，标记其他侧键除Alt外为释放。也就是Ctrl被按下后，对应的侧键和侧键组合可能是：Ctrl+En1，Ctrl+Alt+En1(如果此前Alt已经标记为按下的话)。
如果p41.x>pMiddle.x+avg*250％，则说明左手食指按在了Rmt的位置，手机16标记Rmt按下，标记其他侧键释放。
接着，手机16用p41，p42，p43和p44更新pIndex，pMiddle，pRing和pLittle。
(二)如果p33.x>pRing.x-avg*50％，则说明左手的小指释放了，左手小指在曲面屏右侧的触按点及其坐标失去，手机16标记左手小指释放。如果其后，手机16检测到曲面屏右侧重新生成了4个触按点，则说明左手的小指又按回去了，左手小指在曲面屏右侧的触按点及其坐标失而复得，手机16重新标记左手小指按下。与此同时，手机16把曲面屏右侧重新生成的四个触按点按x值从大到小排序，得到p41，p42，p43和p44。
如果pRing.x-avg*150％<p44.x<＝pRing.x-avg*50％，则说明左手小指按在了Punc的位置，手机16标记Punc按下，标记其他侧键除Ctrl外为释放。也就是Punc被按下后，可能对应的侧键和侧键组合是：Punc或者Ctrl+Punc(如果此前Ctrl已经标记为按下的话)；
如果p44.x<＝pRing.x-avg*150％，则说明左手小指按在了Alt的位置，手机16标记Alt和Punc按下，标记其他侧键除Ctrl外释放。也就是Alt被按下后，对应的侧键和侧键组合可能是：Alt+Punc，Ctrl+Alt+Punc(如果此前Ctrl已经标记为按下的话)。
接着，手机16用p41，p42，p43和p44更新pIndex，pMiddle，pRing和pLittle。
(三)如果pMiddle.x-avg*50％<p32.x<＝pMiddle.x+avg*50％，说明左手无名指释放了，手机16标记无名指释放，否则说明左手中指释放了，手机16标记左手中指释放。如果其后，手机16检测到曲面屏右侧重新生成了4个触按点，则说明左手的中指或者无名指又按回去了，左手中指或者无名指在曲面屏右侧的触按点及其坐标失而复得。
如果此前左手中指标记为释放，则手机16在标记左手中指为按下的同时标记En2为按下，标记其他侧键除Ctrl和Alt外为释放。也就是En2被按下后，可能对应的侧键和侧键组合是：En2,Ctrl+En2,Alt+En2或者Ctrl+Alt+En2(如果此前Ctrl和/或Alt已经标记为按下的话)。
如果此前左手无名指标记为释放，则手机16在标记左手无名指为按下的同时标记Num按下，标记其他侧键除Ctrl和Alt外为释放。也就是Num被按下后，可能对应的侧键和侧键组合是：Num,Ctrl+Num,Alt+Num或者Ctrl+Alt+Num(如果此前Ctrl和/或Alt已经标记为按下的话)。
接着，手机16用p41，p42，p43和p44更新pIndex，pMiddle，pRing和pLittle。
三、如果手机16的曲面屏是3D touch屏，则可以采用“先用与欲按侧键对应的手指加力按一下，马上再放松到自然握持状态”的方法操作Shift、En1、En2、Num和Punc。这时，手指在曲面屏上的触按点用(x,y,p)表示，p代表手指在触按点施加的压力值。手指在加力按下又放松后，相应侧键标记为按下，该侧键什么时候“释放”根据后续操作的侧键由手机16决定，具体情况还可以参照上述第一、二部分的描述。手机16在激活侧键之前的步骤参照上述第二部分的描述。
在侧键激活之后，在Rmt、Ctrl和Alt中没有任何一个标记为按下的情况下，如果手机16检测到曲面屏右侧触按点为四个且有触按点的p值发生了变化，被进行了加力按，则对这四个触按点按x值从大到小排序，得到p41，p42，p43和p44。
如果(p41.p-pIndex.p)/pIndex.p>P(大写P是能够正确区分手指的误操作和正确操作的预定义值,还可以在用户初次使用手机时经过校验为其确定一个新值)，或者p41.p>P1*fct，说明左手食指加力按在了En1的位置，标记En1被加力按；
如果(p42.p-pMiddle.p)/pMiddle.p>P，或者p42.p>P2*fct，说明左手中指加力按在了En2的位置，标记En2被加力按；
如果(p43.p-pRing.p)/pRing.p>P，或者p43.p>P3*fct，说明左手无名指加力按在了Num的位置，标记Num被加力按；
如果(p44.p-pLittle.p)/pLittle.p>P，或者p44.p>P4*fct(上述大写的P1、P2、P3和P4分别是用户左手食指、中指、无名指和小指自然握持在曲面屏右侧时施加在触按点上的压力值，fct是能够正确区分手指的误操作和正确操作的预定义因子，可以在用户初次使用手机时经过校验为它们指定具体的值)，说明左手小指加力按在了Punc的位置，标记Punc被加力按。
之后，如果手机16检测到曲面屏右侧有触按点的p值发生了变化，四个手指都恢复到了自然握持状态，则取消刚才侧 键的加力按标记，并标记该侧键为按下，并同时决定是否对其它先前标记为按下的侧键标记为释放。接着，手机16把重新检测到的四个触按点按x值从大到小排序，得到p41，p42，p43和p44，并用它们更新pIndex，pMiddle，pRing和pLittle。
在侧键激活之后，如果手机16检测到曲面屏右侧只有3个触按点，则说明曲面屏右侧有一个手指释放了。手机16把检测到的三个触按点按x值从大到小排序，得到三个点p31，p32，p33。
(一)如果p31.x<＝pMiddle.x+avg*50％，则说明左手的食指释放了，手机16标记左手食指释放。如果其后，手机16检测到在曲面屏右侧重新生成了四个触按点，则说明左手的食指又按回去了，手机16标记左手食指按下。然后，手机16把这四个触按点按x值从大到小排序，得到p41，p42，p43和p44。
如果pMiddle.x+avg*50％<p41.x<＝pMiddle.x+avg*150％，则说明左手食指按在了En1所在的位置，标记En1按下。
如果pMiddle.x+avg*150％<p41.x<＝pMiddle.x+avg*250％，则说明左手食指按在了Ctrl所在的位置，标记Ctrl和En1按下。
如果p41.x>pMiddle.x+avg*250％，则说明左手食指按在了Rmt所在的位置，标记Rmt按下。
在上述相应的侧键标记为按下后，还要决定是否对其它先前标记为按下的侧键标记为释放。接着，手机16用p41，p42，p43和p44更新pIndex，pMiddle，pRing和pLittle。
(二)如果p33.x>pRing.x-avg*50％,则说明左手的小指释放了，标记左手小指释放。如果其后，检测到在曲面屏右侧重新生成了四个触按点，则说明左手的小指又按回去了，标记左手小指按下。手机16把这四个触按点按x值从大到小排序，得到p41，p42，p43和p44。
如果pRing.x-avg*150％<p44.x<＝pRing.x-avg*50％，则说明左手小指按在了Punc所在的位置，标记Punc按下。
如果p44.x<＝pRing.x-avg*150％，则说明左手小指按在了Alt所在的位置，标记Alt和Punc按下
在上述相应的侧键标记为按下后，还要决定是否对其它先前标记为按下的侧键标记为释放。接着，手机16用p41，p42，p43和p44更新pIndex，pMiddle，pRing和pLittle。
在上述三部分的说明中，虽然没有描述单个侧键双击、三击和多个侧键被同时操作的情形，但很显然本发明也是可以实现这些操作的。本发明可应用于更多的侧键操作方法,在背景技术中提到的PCT申请文件记载了更多可用的侧键操作方法，可以参考。

五、图39为一款平板24，其底部设有2*6阵列实体键盘，在其左上角的边框上设有Shift，在其左侧面设有2Hands，在其背部左侧设有多点触控板28，在其触摸显示屏上设有键盘动态映射区，其部分侧键和侧键组合对应的键盘布局如图43到图48所示。用户的左手握在平板24的左侧，左手的拇指握在Shift处，2Hands由左手拇指根部的突起自然靠压，左手的食指、中指、无名指和小指握在平板背部左侧的触控板28上，在该触控板上形成的四个触按点分别对应侧键En1、En2、Num和Punc。
[根据细则91更正 05.03.2016]　
图42为一款无边框平板29，其底部设有2*5阵列实体键盘，其触摸显示屏上设有键盘动态映射区。除Shift设在其触摸显示屏的左上角外，其侧键布局与平板24的相同。其部分侧键和侧键组合对应的键盘布局如图49到图52所示。可以把公布号为WO/2014/101519的PCT申请披露的无边框平板的夹点当作该款平板的Shift键，并把夹点处的触按动作当作对Shift键的操作。

图53是一款翻转硬键盘平板35。键盘36采用3*5的阵列，通过束带与平板连接，在不用的时候可以翻转到平板的背部。如果键盘36是透明的，则可以在其下的触摸显示屏上动态显示图33到图38所示的键盘布局以及其它没有示出的键盘布局。平板35的侧键布局与平板24的一样。
[根据细则91更正 05.03.2016]　
图56为一款无边框翻转硬键盘平板40。键盘41采用4*4阵列。平板40的侧键布局与平板29的一样，其侧键和侧键组合对应的键盘布局如图21到图28所示。
上述用作键盘的侧键，在非编辑状态下或者非快捷键模式下可以转用作其他键，或者通过双击甚至三击转用作其他键。正如手机14所示，设置在触控板上的侧键不一定非得用作键盘的侧键。显然，本发明也适用于除手机和平板以外的其他类似手持数字设备。当手持数字设备尺寸较大，左手的食指或/和小指够不到设置在右侧的触控板时，就不可能在触控板上设置至少四个侧键，可以把触控板向手持数字设备的背部适当延伸以便食指或/和小指能够够着。只要把触控板设置在手持数字设备的左侧或背部右侧就可适用于左撇子。
六、对于独立的多点触控板或者多点触摸屏，一样可以实现多个位置动态被动确定的按键。图57到图64为一种触控板鼠标42，多个手指可以在其上同时滑动、握放、旋转等。图57、图58和图59分别是用右手的3/4/5个手指实现3/4/5个鼠标键的情形。图中的R1、R2、R3、R4、R5分别表示右手的拇指、食指、中指、无名指和小指。图64为用户用左手五指在触控板鼠标42上实现五个鼠标键的情形，其中，L1、L2、L3、L4、L5分别表示左手的拇指、食指、中指、无名指和小指。由于所有手指或大部分手指都搁置在鼠标板上，而且手腕不用向上屈曲，因此可以大大缓解手指和手腕的疲劳。
以下以用右手在鼠标板42上实现5个鼠标键的情形进行说明。定义R1、R2、R3、R4和R5分别对应第四鼠标键、鼠标左键、鼠标中键、鼠标右键和第五鼠标键。当右手五个手指触按到鼠标板42上时，生成5个触按点p51、p52、p53、p54和p55。鼠标固件对p51到p55参照坐标系43按x值从小到大排序得到pX1、pX2、pX3、pX4和pX5，按y值从大到小排序得到pY1、pY2、pY3、pY4和pY5，同时标记R1、R2、R3、R4和R5为按下。
如果pY1＝pX3，则说明右手的初始触按手势如图59所示，因此pX1、pX2、pX3、pX4和pX5分别对应R1、R2、R3、R4、R5的触按点。接着，鼠标固件把pX1、pX2、pX3、pX4和pX5保存为pThumb、pIndex、pMiddle、pRing和pLittle，并激活鼠标键。
如果pY1＝pX4，则说明右手的初始触按手势如图60所示，因此pY5、pY4、pX3、pX4和pX5分别对应R1、R2、R3、R4、R5的触按点。接着，鼠标固件把pY5、pY4、pX3、pX4和pX5保存为pThumb、pIndex、pMiddle、pRing和pLittle，并激活鼠标键。
如果pY3＝pX1，则说明右手的初始触按手势如图61所示，因此pY5、pY4、pY3、pY2和pY1分别对应R1、R2、R3、R4、R5的触按点。接着，鼠标固件把pY5、pY4、pY3、pY2和pY1保存为pThumb、pIndex、pMiddle、pRing和pLittle，并激活鼠标键。
如果pY1＝pX2，则说明右手的初始触按手势如图62所示，因此pX1、pX2、pX3、pY4和pY5分别对应R1、R2、R3、R4、R5的触按点。接着，鼠标固件把pX1、pX2、pX3、pY4和pY5保存为pThumb、pIndex、pMiddle、pRing和pLittle，并激活鼠标键。
如果pY3＝pX5，则说明右手的初始触按手势如图63所示，因此pY1、pY2、pY3、pY4和pY5分别对应R1、R2、R3、R4、R5的触按点。接着，鼠标固件把pY1、pY2、pY3、pY4和pY5保存为pThumb、pIndex、pMiddle、pRing和pLittle，并激活鼠标键。
在激活鼠标键之后，随着各个手指在鼠标板42上的移动，鼠标固件不断刷新pThumb、pIndex、pMiddle、pRing和pLittle或者通过上述步骤不断更新pThumb、pIndex、pMiddle、pRing和pLittle。
假定鼠标板42是一块3D touch鼠标板，每个触按点的坐标用(x，y，p)表示。
当有一个手指释放，触按点由5个变成4个时，鼠标固件把检测到的4个触按点p41、p42、p43和p44分别与pThumb、pIndex、pMiddle、pRing和pLittle进行循环匹配(即同时比较两个触按点的x和y是否均相等)，得到没有匹配上的触按点，接着根据没有匹配上的触按点确定刚才释放的手指，并标记该手指为释放。比如，如果pIndex没有被匹配上，则说明R2释放了，标记R2为释放。当鼠标固件重新检测到鼠标板42上又生成了5个触按点时，说明刚才释放的R2又按回去了，鼠标固件标记R2按下，同时发出鼠标左击的指令。然后，用新检测到的触按点更新pThumb、pIndex、pMiddle、pRing和 pLittle。
或者当鼠标固件检测到有触按点的p值发生了变化时，通过参照上述第三部分的描述，判断当前操作的手指，并发出相应的鼠标键指令。比如，如果鼠标固件检测到了pRing的p值发生了变化，R4进行了加力按，则说明刚才R4进行了操作；在检测到pRing的p值又发生了变化，R4又自然触按在鼠标板42上后，鼠标固件发出鼠标右击的指令，并同时更新pThumb、pIndex、pMiddle、pRing和pLittle。可见，对于支持3D touch的触控板，可以同时用两种方法来操作按键。
图57、图58和图64的情形一样可以通过上述方法实现。
按照上述办法，还可以在一块支持多点触控功能的触摸显示屏上，用手指模拟鼠标；也可以把一个支持多点触控功能的平板电脑改造成为一个鼠标，对于有些平板电脑，比如支持蓝牙4.0以上的平板，甚至只要编写一个专门的鼠标app把平板触摸屏上的手指操作解释成为鼠标操作就可以了。
七、对于大尺寸的多点触摸屏或者多点触控板，还可以同时用双手的部分或者全部十个手指触按到触摸屏或触控板上，在实现滑动、握放和旋转等操作的同时，实现更多位置动态被动确定的按键。
图65到图68是一种大尺寸的触摸显示设备44。在用户初次使用设备44时，提示用户如图65那样用两只手触按在设备上44上，然后分别根据用户左右手的各5个触按点虚拟出两个圆弧aL0和aR0，然后计算aL0和aR0半径的平均值r0，保存在设备44里。
在用户正常使用设备44之后，当检测到在触摸显示屏上生成10个触按点时，设备44参照坐标系45把10个触按点按x值从小到大排序，得到pL1、pL2、pL3、pL4、pL5和pR1、pR2、pR3、pR4、pR5。接着根据pL1到pL5和pR1到pR5虚拟出两个圆弧aL和aR，然后用aL和aR的半径rL和rR分别与r0进行比较。
如果rL和rR有一个或者两个都与r0差距较大，则说明双手在设备44上的触按手势如图67所示，不正确，提示用户改正。
如果rL和rR两个都与r0接近，但aL的圆心在aL的右侧且aR的圆心在aR的左侧，则说明双手在设备44上的触按手势如图68所示，不正确，提示用户改正。
如果rL和rR两个都与r0接近，且aL和aR的圆心分别在aL和aR的下面，则说明双手在设备44上的触按手势如图65所示，正确。
如果rL和rR两个都与r0接近，且aL的圆心在aL的左侧，aR的圆心在aR的右侧，则说明双手在设备44上的触按手势如图65所示，正确。
在确定用户的触按手势正确后，把pL1、pL2、pL3、pL4、pL5和pR1、pR2、pR3、pR4、pR5分别按照上述第六部分的方法与L1、L2、L3、L4、L5和R1、R2、R3、R4、R5对应起来，并在后续的操作中，随着各个手指的不断移动及时更新各个手指对应触按点的坐标。当有手指进行按键操作时，参照上述第一、二、三和六部分的方法，先确定动作的手指，然后再确定操作的按键。
当不需要在多点触控板/触摸屏上设置和触按点一样多的按键时，可以忽略用不到的按键。比如，图59所示的触控板鼠标，当不需要5个鼠标键时，就可以忽略用不到的鼠标键。正如曲面屏手机16所示，以上关于多点触控板上的描述同样适用于多点触摸屏，反之亦然。
上述在多点触控板或者多点触摸屏上实现按键的方法，不仅实现了按键位置的动态被动确定，而且也做到了以手指定按键，即用户只要记住相应手指代表的按键即可，相应手指的动作就是对相应按键的操作。
