Description

输入装置及键位划分方法 技术领域
本发明属于终端信息交互设备领域，尤其涉及一种高效的智能输入装置。
背景技术
以计算机和手机为代表的终端设备发展到今天，已经越来越迅速的在向小型化、便携化发展，人类与这些终端设备之间的信息交互，也从单一的文字输入逐渐向语音、眼睛、体感等全方位展开。但目前最主流的信息输入方式，还仅局限于键盘和鼠标两种传统装置。键盘的使用是平摊开的，有一定宽度，使用者在使用键盘时，需要用手去寻找键盘上面的定位键“通常为F和J键”，以此为定位基础并展开到其余键位，所有键位共同组成键盘的输入区域；而对于鼠标，虽然自由度更大，但由于键位太少，又不适合文字输入等一系列的复杂输入操作。二者因为自身明显的优点和不足，既不能相互替代，就只能互相交叉使用。
交叉使用所带来的不足之处，在于每次使用者的手离开键盘去操作鼠标后，双手回到键盘再次进行输入时都必须先去寻找两个定位键，否则无法正确输入。为此大多数笔记本采用触摸区域想要来代替鼠标输入，最大程度上想要保持使用者在鼠标和键盘间切换时不用抬起双手，避免每次的重复定位动作，但触摸区域自身的输入便捷性与鼠标相比仍有一些差距，同时又因为离键盘太近，在使用者进行键盘输入时经常出现误操作。很多厂商在设置触摸区域的同时还对其设置了开关键，由用户自行选择是否接受这一出错率较高的便捷方式。
可以说，至今仍没有一种设备既可以实现键位的精准输入，又能同时顺畅 的进行方向操作。
发明内容
本发明目的在于提供一种高效的输入装置及键位的划分方法，并提供以下技术方案：
一种输入装置，包括握持部和按键区，所述按键区包括第一键区和第二键区，所述第一键区位于所述握持部和所述第二键区之间，所述第一键区和所述握持部在第一方向上依次分布，所述第二键区在第二方向上延伸，所述第一方向垂直于所述第二方向，所述第一键区和所述第二键区均设有至少一个键位，用于输入指令。
本发明还涉及一种在输入装置上划分键位的方法，所述输入装置包含按键区、压力传感器、数据处理器；所述压力传感器设置于所述按键区内，所述数据处理器电连接所述压力传感器，所述按键区包括第一键区和第二键区；所述压力传感器感应操作者手指的触碰信息，并将所述触碰信息传递给所述数据处理器；当所述触碰信息的数量多于一个时，所述数据处理器根据所述触碰信息的位置，在每两个相邻触碰信息之间划分出一条分界线，所述第一键区远离所述第二键区的边界为第一边界，所述第二键区远离所述第一键区的边界为第二边界，每条所述分界线均分别朝向所述第一边界和所述第二边界延伸，所述第一键区和所述第二键区之间设有分割线，以使所述多条分界线与所述分割线、所述第一边界及所述第二边界相交，将所述按键区划分为多个键位，每个所述键位对应不同的输入指令。
运用本发明的输入装置，通过将握持部和按键区集成在同一设备上，并将按键区延伸到握持部和按键区的结合部，形成第一键区，第一键区与第二键区 分开设置，且按键延伸方向相互垂直，两个按键区相对于握持部的直线距离都控制在一定范围内。握持部与第一键区的组合在结构上类似于手柄，可实现本输入装置的方向指令输入。人手掌置于握持部，能够方便的同时在第一键区和第二键区进行输入，键位输入和鼠标输入都可以集成在一个装置上，以此解决鼠标和键盘的结合问题。
采用本发明方法对输入装置进行多键位的划分，可以将输入装置进行进一步的逻辑优化，在操作者双手不需要移动的情况下，只通过手指的按压，实现多键位的指令输入，结合本装置的结构或逻辑设定，可以实现高效的输入操作。
附图说明
为了更清楚地说明本发明的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明一种实施方式中输入装置的示意图；
图2是本发明一种实施方式中输入装置键位划分的示意图；
图3是本发明一种实施方式中输入装置键位划分平面示意图；
图4是本发明一种实施方式中输入装置鼠标模式的示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
如图1所示的输入装置，包括握持部100和按键区200，在本实施例中，输入装置是一个中心对称的结构，握持部100为本装置顶部的球形结构，握持 部包括冠顶101和连接部102。按键区200包括第二键区220和位于所述连接部102和所述第二键区220之间的第一键区210。一种实施方式中，第二键区220呈圆盘状，第一键区210呈圆锥状。所述第一键区210靠近所述第二键区220一端半径大于靠近所述连接部102的一端的半径。图1中可以明显得出，所述第一键区210和所述握持部100在第一方向001上依次分布，所述第二键区220在第二方向002上延伸，所述第一方向001竖直向上，垂直于所述水平设置的第二方向002。所述第一键区210和所述第二键区220均设有至少一个键位，用于输入指令。此时，所述第一键区210与所述第二键区220相对于所述握持部100的距离满足如下条件：当操作者的手掌放置于所述握持部100的所述冠顶101上时，手指自然下垂就可以触摸到所述第二键区220，手指弯曲时可以触摸到所述第一键区210，此时所述操作者可以分别实现两个键位的输入动作。
在本实施例中，所述第一键区210与所述第二键区220是连通的，在另一些实施例中所述第一键区210与所述第二键区220中间也可以设置隔离带，不作连通设计，只要相互的位置关系依照本发明限定的布置即可。
进一步的，鉴于不同年龄，不同身高的人手掌大小存在差异性，本发明输入装置还在结构适应性上设计了若干匹配环节，例如：在所述握持部100处设置尺寸调节结构110，所述尺寸调节结构110可调节所述握持部100体积大小。一种实施方式中，尺寸调节结构110可以为(但不限于)气囊111，所述气囊111可通过充放气方式调节所述握持部100的体积大小，另外还可以通过液体的充放来调节尺寸调节结构110的体积，达到相同的效果。在另一实施方式中，所述尺寸调节结构110包括滑动机构112，通过所述滑动机构112调节所述握持部100背离所述第二键区220的一侧相对所述第二键区220所在平面的垂直距离，该滑动机构112设于所述连接部102与所述第一键区210的连接位置。 具体而言，所述连接部102下部设有开口，可收容所述第一键区210，滑动机构112设置在连接部102和第一键区210之间，所述滑动机构112可以是带多级定位卡槽的机械伸缩结构，也可以是丝杆、螺纹等通用的距离调节结构，此处不作明确限定。
相应的，因为所述握持部100以及第一键区210自身外形的变化，本发明输入装置的外表层300可以设为柔性，所述柔性表层300贴合在所述握持部100以及所述第一键区210外表面，具有弹性伸缩功能，在所述气囊111通过充放气的方式调节体积，或所述滑动机构112调整所述握持部100的高度时，外表层300随尺寸调节结构110调节输入装置外部形状的改变而伸缩，保持对内部结构的覆盖保护。
需要提出的是，本实施例中所述第一方向001与所述第二方向002虽然垂直，但并不要求所述第二键区220相对于所述第一键区210完全垂直延伸，只要所述第二键区220在所述第二方向002的投影上是向远端延伸即可认为属于本发明的保护范围。所述第一键区210与所述握持部100也定义为在所述第一方向001上依次排列，在本发明中解释为二者的投影在所述第一方向001上依次排列。
一种实施方式中，所述第二键区220采用圆盘结构，完全环绕所述第一键区210，且所述第一键区210处于所述第二键区220的几何中心。在其他一些实施例中，所述第二键区220还可以采用扇形结构，部分环绕所述第一键区210，只要操作者的手掌处于所述冠顶101，且通过前述的调整结构110调整到适当位置时，能够保证操作者的手同时触碰到所述第一键区210和所述第二键区220，对于所述第二键区220的形状就不做特别限定。所述第二键区220的形状还可以为：两边平行同时向所述第二方向002延伸的长方形，或者与所述第二方向002呈一定夹角延伸的长方形，甚至为边界不规则的形状都可以满 足本操作的需要。
在另一实施方式中，当所述第一键区210不在所述第二键区220的几何中心，只要满足上述的操作者手部放在所述冠顶101，且同时可以触及所述第一键区210和所述第二键区220，仍属于本发明要求保护的范围。
一种实施方式中，在所述第一键区210和所述第二键区220的所述柔性表层300下设有压力传感器310，所述压力传感器310可以感应操作者手指的“不接触”、“触摸”和“按压”三种状态，所述压力传感器310可以单独设置在所述第一键区210或所述第二键区220，也可以在两个键区中同时设置。所述压力传感器310用于感应各所述键位的输入指令。
一种实施方式中，所述压力传感器310可以集成在所述柔性表层300中，因此要求所述压力传感器310同样具备弹性，并随所述握持部100和所述第一键区210的体积、距离变化而伸缩。通过所述压力传感器310的设置，本发明装置不用在所述第一键区210或所述第二键区220处额外设置按键，只需要触碰按压本输入装置的相应键区即可完成输入工作。
具体而言，所述第二键区220包括相对设置的内边缘221和外边缘222，所述内边缘221连接至所述第一键区210，二者平滑过渡。所述外边缘222在所述第二方向002上远离所述第一键区210，同时所述外边缘222相对于所述第二键区220呈弯曲状，在本实施例中为向所述握持部100方向翘起的环形圆弧状，所述外边缘222的边线高于所述内边缘221的边界，即所述外边缘222在所述第一键区210上的垂直投影位于所述内边缘221和所述握持部100之间。操作者在操作本发明输入装置时，因为所述外边缘222的翘起，手指与向所述第二方向002远处延伸的所述外边缘222的距离没有被同步拉远，仍在可以触及到的范围之内。
需要指出的是，为了达到上述手指与所述外边缘222的距离不被同步拉远 的目的，除了本实施例中的将所述外边缘222呈圆弧状翘起的形态外，还可以将所述第二键区220设置为倾斜于所述第一方向001延伸，所述外边缘222在所述第一方向001上的投影依旧高于所述内边缘221。
通过所述外边缘222在所述第一方向001上的投影高于所述内边缘221的设置，所述第二键区220的有效输入面积被进一步放大。
一种实施方式中，可以在所述第二键区220的所述外边缘222一端增设第三键区230，所述第二键区220和所述第三键区230在所述第二方向002上依次分布，所述第三键区230也设有至少一个键位，同时设置所述压力传感器310，从而实现输入指令。此时，本发明装置总共有3个独立键区可以输入指令。
由于所述第一键区210和所述第二键区220之间，以及所述第二键区220和所述第三键区230之间只是内部逻辑上的划分，操作者无法直观的区分各键区之间的边界，本发明输入装置还可以设置发光模块320，所述发光模块320用于在所述柔性表层300处发光，将内部的键区划分通过边界光线的形式呈现给操作者，辅助操作者进行更精确的输入。
一种实施方式中，将所述第二键区220与所述第三键区230的外表面进行差异化处理，制造不同的触感，也可以帮助操作者区分所述第二键区220与所述第三键区230。所述差异化处理包括在所述第二键区220与所述第三键区230的外表面使用不同的材质、或采用不同的粗糙度、或采用不同的表面处理方式等手段。
具体而言，所述第二键区220处设置的压力传感器310还连接了数据处理器340，在操作者的手指触碰所述第二键区220外表面时，所述压力传感器310能够感应到多个手指的位置，所述数据处理器340根据所感应到的手指位置，在所述第二键区220的外表面划分出与感应到的手指数量相同且依次间隔排 列的分界线223，用于将所述第二键区220划分为比感应到的手指数量多一个的键位01，每一个所述键位01的所述分界线223都从所述第二键区220和所述第一键区210的分界(即所述内边缘221处)延伸至所述第二键区220远离所述第一键区210的所述外边缘222处。在所述键位01划分完毕后，所述数据处理器340按照预先设定的编码表将对应的按键编码发送给传输模块350，所述传输模块350可以使用现有的技术，比如USB等有线方式、蓝牙等无线方式，负责连接终端设备，并且将所述键位01对应的编码键值发送给连接的终端设备。每一个所述键位01都对应一个独立的输入指令，操作者可以在各个不同的所述键位01上进行按压操作，输入指令。当然，在键位01划分完毕之后，数据处理器340也可不将按键编码通过传输模块350发送给终端设备，而是存储在输入装置内部，待某一个位置的键位01被触发之后，数据处理器340再根据按键编码表确定该位置的键位01所对应的按键编码，然后再把此键位01被触发的信息通过传输模块350发送给终端设备。
一种实施方式中，所述第二键区220被5条所述分界线223划分出6个相邻的键位21～键位26，用于分别对应操作者的五个手指位置，此时本发明输入装置总共包括了所述第一键区210，所述第三键区230以及6个所述键位01总共8个相互独立的所述键位01，可对应8个不同的输入指令，相对于传统鼠标而言已经有了更多的输入指令。当然，操作者也可以根据个人操作习惯，选择放置4根或4根以下的手指对所述第二键区220进行触摸，此时所述第二键区220被划分的所述键位01数量为5个或5个以下，最少1个。本发明装置可以预先设定好当本装置在5个或5个以下的划分情况下每一个所述键位01的对应输入指令，操作者可以根据个人需要对指令进行调整。
需要提出的是，各所述键位01的宽度大于放置于所述键位01上的手指宽度，此处的宽度是指所述键位01沿周向的尺寸，以保证每一个手指在其对应 的所述键位01上进行按压输入时，能够对应唯一的输入指令，不会因为所述键位01的宽度太小而同时跨两个或两个以上的所述键位01进行输入。
以本实施例为例，见图3，当操作者的五个手指全部放置于所述第二键区220外表面时，由于5根手指的张开，所述压力传感器310可以明显采集到5个触碰的信号，所述压力传感器310将采集到的触摸位置信息传递给所述数据处理器340。触碰信号带有角度信息，在所述压力传感器310内预设x轴，原点设在所述第一键区210的几何中心位置，采用极坐标以所述x轴为角度值0的起点，顺时针为正，所述数据处理器340通过分析触碰信号所含的角度信息，按照角度值将所述第二键区220进行所述键位01的划分。
假设当前所述触碰信号包括第一信号和第二信号，所述键位01的分界线223设定依据为：
当距离所述第一信号的位置正负Ω角度范围内有所述第二信号，则所述第一信号的中心角度值a和所述第二信号的中心角度值b之和的一半，即角度值(a+b)/2定义为第一角度，所述第一角度处的射线就对应所述第一信号所对应的键位和所述第二信号所对应的键位的分界线223在所述平面003上的投影。
当距离所述第一信号的位置正Ω角度范围内无所述第二信号，则所述第一信号的正时针方向上的分界线为从所述第一信号的中心a开始，沿该方向角度值为σ的射线为所述分界线223。
当距离所述第一信号的位置负Ω角度范围内无所述第二信号，则所述第一信号的逆时针方向上的分界线为从所述第一信号的中心a开始，沿该方向角度值为σ的射线为所述分界线223。
Ω和σ的取值可以任意确定，优选的Ω取40°，σ取30°。
完成所述分界线223的设定后，所述数据处理器340将所述第二键区220 按照触碰信号划分成了6个键位21～键位26，其中所述键位26是没有手指触碰的空白键位，再通过判断手指按压位置的角度值就可以将该触碰信号判定它所属的所述键位01。例如，将所述第二键区220划分的键位01分别为：所述键位21(8°～45°)；所述键位22(46°～95°)；所述键位23(96°～135°)；所述键位24(136°～165°)；所述键位25(166°～205°)；所述键位26(0°～7°，206°～360°)。当检测到手指按下位置角度值为77°的时候，按照上述的划分规则，手指按下区域被判断在所述键位22。
对于所述键位01的划分，操作者可以根据自身需要，选择一次划定后限定有效时间，如1分钟，5分钟，10分钟，30分钟或其余任意时间，或设定为手指不接触后可以立即自动清除，也可设定手指不接触后延迟一定时间再清除。
一些实施例中，在本输入装置中设定复位指令，该复位指令优选设置在所述冠顶101处，且所述握持部100的表面也设有所述压力传感器310，用于感知所述冠顶101处的压力。当操作者手掌置于所述冠顶101处时，所述压力传感器310感应到压力，所述数据处理器340开始启动划分机制待命，等感应到操作者的手指触碰后，所述数据处理器340立即开始划分工作。待操作者手掌离开所述冠顶101后，所述数据处理器340立即清除本次划分状态，或等待设定的时长后再清除本次划分状态。为了防止误触，还可以将复位指令设计稍微复杂一点，如手掌轻触两次所述冠顶101，或手掌在所述冠顶101上旋转等。
在另一些实施例中，所述复位的指令可以直接设置在所述第二键区220上，操作者按压所述第二键区220达到一定力度，或进行一组制定的操作后，所述数据处理器340启动复位机制将当前划分数据清零，并重新启动划分机制等待划分。
通过这样的设置，操作者在每一次手掌离开本发明输入装置后，都不需要 特意按照之前的握姿或角度去重新寻找各手指对应的键位，而是通过所述压力传感器310的感应，针对操作者每一次的握持状态，由所述数据处理器340来实际划分各所述键位01，对于操作者来说省去了每次寻找定位键的麻烦，可以获得更自如随意的输入体验。
一些实施例中，在划分所述第二键区220的同时，将所述第二键区220中所述分界线223双向延伸，对所述第一键区210和所述第三键区230也进行键位的划分，见图3。延伸入所述第三键区230并到达所述外边缘222处的所述分界线223，将所述第三键区230划分为两个相互独立的键位3。依次的，5条所述分界线223都完成对所述外边缘222的延伸后，所述第三键区230与所述第二键区220一样，被划分为6个相邻的键位31～键位36。
相应的，将所述分界线223向所述握持部100延伸，到达所述第一键区210与所述连接部102的交界处，可以将所述第一键区210也区分为6个独立键位11～键位16，此时本发明输入装置共有18个独立键位可供操作者进行指令输入，大大丰富了本输入装置的适用性。
对于各个所述键位01的按压输入，还可以分为短时按压和长时按两种模式，对应不同的输入指令，可以将18个输入指令提升到36个输入指令。
由于所述第一键区210的展开面积相对较小，为保证更准确的输入体验，一方面本装置的所述第一键区210需要具备一定的体积，以保证展开宽度足以匹配最多六个所述键位1的宽度，另一方面对于所述第一键区210内的每一个独立键位1的划分，也要在实现宽于手指的前提下尽量控制总体宽度，不使所述第一键区210显得过于臃肿，挡住操作者对其余键区的操作。
本发明输入装置还包括反馈单元330，用于在各所述键位01划分完成后发出反馈信号给使用者。所述反馈单元330可以是振动反馈给操作者的手部，也可以是发出声音等操作者可以快速获取到反馈信息的功能组件。另一方面， 当所述数据处理器340因为表面异物、手指触碰信号相隔距离太近、感应失灵等各种原因无法完成所述键位01的划分时，所述反馈单元330也可以给操作者提供反馈信号，要求操作者重新触摸所述第二键区220，以重新划分所述键位01。显然，划分成功和划分失败的反馈信号是有区别的，例如采用振动反馈时，划分成功为振动一下就停止振动；划分不成功为振动两下，且在手指抬离所述第二键区220之前连续间隔振动，每次振动两下，以提醒操作者划分未成功。同时，所述发光模块320在划分完成后，对各所述键位01的所述分界线223也实现发光显示，优选的，还可以在每个所述键位01的表面上显示出该键位当前所对应的输入指令，帮助操作者做出更准确的输入操作。
一种实施方式中，所述第一键区210背离所述握持部100的端部设有方向传感器360，所述方向传感器360用于感应所述第一键区210的偏移和转动信号，并将所述感应到的信号转换为输入指令，即所述第一键区210与所述握持部100形成一个摇杆2100，所述摇杆2100底部设有所述方向传感器360，可以感知所述摇杆2100的各种方向动作，所述摇杆2100可以在终端上实现光标的移动，由此实现类似鼠标的功能。
在操作者使用本发明输入装置时，由所述摇杆2100和所述18个键位的组合，可以实现丰富的输入指令。每个所述键位01可以预设最多八个备选输入指令，然后通过所述摇杆2100的八个方向进行二次选择。也可以对单个所述键位01内设置两个对应字母，在操作者完成按压输入操作后，系统将所有可能出现的字母组合结果全部陈列在显示器上，并将相应的方向操作可对应的输入选择呈现在显示器上，由操作者操控所述手柄2100来选择想要输入的指令。当可能出现的字母组合超过8个时，系统可以根据词频来筛选前8组供操作者选择。
当操作者在终端上浏览网页，或观看电视剧等更多采用鼠标模式操作的时 候，过多的键位划分并不完全适应操作者的输入需要，此时可以在本装置中设置鼠标/键盘切换指令，本发明装置在接到切换鼠标的指令时，立即清除之前的键位分区，将所述键区200划分为左键区201和右键区202，所述左键区201对应鼠标的左键，所述右键区202对应鼠标右键。优选的，还可以在所述左键区201和所述右键区202之间设置一段滚轮区203(见图4)，操作者手指在所述滚轮区203上按压时对应鼠标的中间滚轮输入。对于键盘/鼠标模式之间的切换，可以采用顺时针或逆时针转动所述手柄2100来实现。
在另一些实施例中，鼠标模式仍可以沿用所述第二键区220内的所述键位01来划分。此时所述键位21～所述键位25的输入指令对应如表1：
Figure PCTCN2017102707-appb-000001
表1
进一步的，操作者还可以同时使用两个本发明输入装置，相互配合来实现指令的输入。当两个本发明装置成对使用时，最多可以提供30个独立键位供操作者输入，此时普通键盘上的26个字母键都可以独立设置，同时再设置诸如空格键、回车键、删除键、ctrl键等常用的功能键，配合两个所述手柄2100的方向操作，完全可以代替键盘的功能，并实现丰富的拓展。
此外，鼠标模式和键盘模式还可以同时混用，而不用刻意区分到底是哪种模式。具体地，当用户的手掌仅触摸到握持部100，而手指与第一键区210、第二键区220及第三键区230都分开时(即手指保持悬浮状态)，此时可通过摇 动握持部110来输入方向指令，如鼠标光标的移动。在手指悬浮状态下，由于第一键区210、第二键区220及第三键区230均未被触摸，因而不会触发键位01，因而不会影响到方向指令的输入。当用户需要输入字母或字符时，手指可在第一键区210、第二键区220及第三键区230对应的键位01上触摸，此时握持部110的移动方向不影响键位01的触发。
在一种实施例中，在所述第一键区210，所述第二键区220和所述第三键区230中，将由同样两条所述分界线223画出的所述键位01定义为一列，则两个本发明装置每个总共被五条所述分界线223划分为6列所述键位01，可以设定30个所述键位01的对应输入指令表如下：

表2
表2中括号内的内容，为长时按该键位所对应的输入指令。
对于具体的输入方式，本发明不作特别限定。但有一点优化措施需要提出，即当成对配合使用的两个本发明装置同时使用时，操作者可以设定一个主装置，另一个为辅助装置，在进行键位划分、键盘/鼠标切换、反馈等动作的时候，或者在两个装置同时输入且指令冲突的时候，系统默认在主装置上做出的操作指令，以免发生冲突或逻辑错误。
进一步的，两个输入装置也可以被设定为一个装置采用鼠标模式，另一个装置采用键盘输入模式，或者两个装置为相互独立的游戏手柄模式等，都可以根据操作者的需要对本发明装置进行任意设置，本发明不再一一列举。
本发明还涉及一种在输入装置上划分所述键位01的方法，所述输入装置包含按键区200、压力传感器310和数据处理器340，所述压力传感器310设置于所述按键区200内，所述数据处理器340电连接所述压力传感器310，所述按键区200包括第一键区210和第二键区220。当操作者手指触碰所述按键区200时，所述压力传感器310感应到每一个手指的触碰信息，并将全部的所述触碰信息传递给所述数据处理器340。当所述触碰信息的数量多于一个时，所述数据处理器340根据所述触碰信息在相邻两个触碰信息之间划分出一条 分界线223，每条所述分界线223均贯穿整个所述按键区200，所述第一键区210远离所述第二键区220的边界为第一边界211，所述第二键区远离所述第一键区的边界为第二边界222，每条所述分界线223均分别朝向所述第一边界211和所述第二边界222延伸，所述第一键区210和所述第二键区220之间设有分割线221，以使所述多条分界线223与所述分割线221、所述第一边界211及所述第二边界222相交，此时所述分界线223将所述按键区200划分为比操作者触碰的手指数量多一个的键位01，每个所述键位01都对应操作者不同的输入指令。
一种实施例中，设定两个相互垂直的第一方向001和第二方向002，所述第一键区210在所述第一方向001上朝远离所述第二键区220的方向延伸，所述第二键区220在所述第二方向002上朝远离所述第一键区的方向001延伸。相邻两条所述分界线223之间互不交叉，在垂直于所述第一方向001的平面003上，相邻两条所述分界线223的投影之间最小距离大于所述压力传感器310感应到的触碰信息所对应的手指宽度。
优选的，以所述按键区200的几何中心在所述平面003的投影为原点，向外发出射线，所述分割线223在所述平面003上的投影与所述射线重合。为了保证操作者在操作时各手指的键位位置尽量贴合握持时的初始手指位置，可以将所述分割线223的划分定义为平分两个相邻手指之间的所述按键区200的区域，即以两个相邻所述触碰信息的中心连线为基础，所述分割线223在所述平面003上的投影对应的射线，穿过所述两个相邻中心连线的中点。
一种实施例中，在所述压力传感器310内预设x轴，原点设在所述按键区200的几何中心位置，采用极坐标以所述x轴为角度值0的起点，顺时针为正来进行所述键位01的划分，见图2。
当操作者的五个手指全部放置于所述第二键区220外表面时，由于5根手 指的张开，所述压力传感器310可以明显采集到5个触碰的信号，所述压力传感器310将采集到的触摸位置信息传递给所述数据处理器340。所述数据处理器340相对于所述压力传感器310内预设的x轴，分析触碰信号所含的角度信息，按照角度值将所述第二键区220进行所述键位01的划分。
假设当前所述触碰信号包括第一信号和第二信号，所述键位01的分界线223设定依据为：
当距离所述第一信号的位置正负Ω角度范围内有所述第二信号，则所述第一信号的中心角度值a和所述第二信号的中心角度值b之和的一半，即角度值(a+b)/2定义为第一角度，所述第一角度处的射线就对应所述第一信号所对应的键位和所述第二信号所对应的键位的分界线223在所述平面003上的投影。
当距离所述第一信号的位置正Ω角度范围内无所述第二信号，则所述第一信号的正时针方向上的分界线为从所述第一信号的中心a开始，沿该方向角度值为σ的射线为所述分界线223。
当距离所述第一信号的位置负Ω角度范围内无所述第二信号，则所述第一信号的逆时针方向上的分界线为从所述第一信号的中心a开始，沿该方向角度值为σ的射线为所述分界线223。
Ω和σ的取值可以任意确定，优选的Ω取40°，σ取30°。
一些实施例中，所述按键区200沿垂直于所述第二方向002的方位设有分割线224，所述分割线224在所述第二键区220上还划分出所述第三键区230，所述第二键区220位于所述第一键区210和所述第三键区230之间，所述第三键区230远离所述第二键区220的边界为所述第二边界222。这种方案相对于之前的实施例，在所述按键区中多划分出一组所述键位01，可以设置更多的输入指令。
本发明输入装置，以操作者手掌置于握持部为基准，在操作者手指可触及的范围内按本发明方法一步步有秩序的设置键位，使得本输入装置能实现的输入指令越来越多，同时保证每一个键位的独立可操作性，最终得到一个兼具鼠标的自由度与键盘的多键位精准输入于一身的高效输入装置。再针对本发明装置的结构适用性、操控准确性、人机交互能力和输入方式设置等做了进一步的优化设计，使得本发明输入装置适用范围更广，用户友好度更高，易于使用。
本发明方法，对于输入装置进行了清晰的逻辑划分，可以在较单一的输入装置上实现复杂的输入指令操作，定位准确，可靠性高，提升输入装置的可操作性。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
