手写板、手写板装置及书写控制方法 技术领域
本申请涉及手写识别领域，尤其涉及一种手写板、手写板装置及书写控制方法。
背景技术
传统的记事本将文字内容记录在纸张上，当需要查询记事本中的特定的文字内容时，需要逐页查找，导致查找效率低下。同时，由于纸张固有的物理特性，容易遭到损坏，不利于文字内容的长期保存。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
请参阅图1，图1为本申请一实施方式提供的书写控制***1000的方框示意图。书写控制***1000包括手写板装300和电子装置500。手写板装置300通过网络600与电子装置500通信连接。进一步地，手写板装置300包括手写板100和手写笔200，且所述手写板100和手写笔200也可通过网络600通信连接。可以理解，网络600可为互联网(Internet)、按需虚拟专线网(On-Demand virtual Lease Line)、包括WIFI、蓝牙在内的无线网(Wireless network)、包括GPRS网络、CDMA网络在内的电话网、广播电视网等。所述手写板100通过感测所述手写笔200的书写操作生成书写笔迹。可以理解，在一实施例中，手写板100设置在电子装置500上，手写板100为电子装置500上的一输入设备，且受电子装置500的控制。
请同时参阅图2-3，其中图2为本申请一实施方式提供的手写装置300的结构示意图，图3为图2中手写板100的模块示意图。如图2中所述，所述手 写笔200可分离地安装于所述手写板100上。当需要进行书写时，将所述手写笔200从所述手写板100上取下即可。
所述手写板100包括触摸板10和处理器20，所述触摸板10与所述处理器20电连接。所述触摸板10包括书写区11及操作区12，所述操作区12位于所述书写区11的一侧。所述触摸板10响应所述书写区11感测所述手写笔200的书写操作并生成第一触控坐标数据，且还响应所述操作区12所接收到的第一特定操作并生成调整指令。所述处理器20获取所述第一触控坐标数据，并依据所述第一触控坐标数据生成书写笔迹，在生成所述书写笔迹的过程中，所述处理器20还依据所述调整指令对所述书写笔迹进行调整。如此，本申请所提供的书写装置300可在书写过程中对书写笔迹进行相应的调整。
其中，所述处理器20可以是中央处理单元(Central Processing Unit，CPU)，还可以是其他通用处理器、数字信号处理器(Digital Signal Processor，DSP)、专用集成电路(Application Specific Integrated Circuit，ASIC)、现场可编程门阵列(Field-Programmable Gate Array，FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等，处理器是手写板100的控制中心，利用各种接口和线路连接整个手写板100的各个部分。
在本实施方式中，所述书写区11设置有显示屏，也即所述书写区域11具有显示功能，即所述书写区11还可显示生成的书写笔迹。所述操作区12未设置显示屏，不具有显示功能，仅用于响应用户输入的第一特定操作。在其他实施例中所述操作区12也设有显示屏，具有显示功能，即整个所述触摸板10为触控显示屏，将所述触控显示屏的一部分划分为书写区11，另一部分划分为操作区12即可。其中，所述书写区11和所述操作区12的具***置关系在此不做限定，优选地，操作区12位于所述书写区11的左侧以方便书写。
具体地，所述第一特定操作包括但不限于单击所述操作区12、单指触摸所述操作区12并从所述操作区12的一侧滑向另一侧(即单指滑动)、双指触摸所述操作区12并从所述操作区12的一侧向另一侧滑动(即双指滑动)等。所述调整指令包括笔迹颜色调整指令、笔迹类型调整指令或笔迹粗细调整指令。其中，所述笔迹类型包括但不限于圆珠笔笔迹、钢笔笔迹、签字笔笔迹、 毛笔笔迹、铅笔笔记等。
可以理解，每一调整指令对应不同的第一特定操作。例如，可以通过单击所述操作区12来改变笔迹类型；可以通过在所述操作区12上单指滑动来改变笔迹的颜色；可以通过在所述操作区12上双指滑动来改变笔迹的粗细。当然，每一调整指令与第一特定操作的对应关系不限于此，可以依据具体的需求而进行设定，例如，也可以通过双指滑动来改变笔迹颜色。
需要说明的是，在具体的设计中，笔迹的类型的变换可以通过单击操作区12上的不同位置来确定；笔迹的粗细可以随着滑动而逐渐***也可以随着滑动逐渐变细；所述笔迹颜色随着滑动可以渐变为其他不同的颜色，对于具体的变换对应关系在此不做具体限定。
请再参图4，图4为本申请一实施例公开的手写笔200在手写板100上进行书写的示意图。所述手写笔200在书写时，可以在所述书写区11上覆盖书写纸400，在书写纸400上形成真实笔迹(如图6中a所示)并同时驱动所述手写板100形成与所述真实笔迹对应的书写笔迹。在本实施例中，所述触摸板10为电容式触摸板，用于感测手写笔200或用户手指的接触产生的电容变化确定发生触控的位置，而得到第一触控坐标数据。
请再次参阅图3，在一些实施例中，所述触摸板10可以包括触控传感器11和触摸控制器12。所述触控传感器11用于感测所述手写笔200和/或所述用户手指与触控板10的接触而产生相应的触控感应信号，所述触摸控制器12根据接收到的触控感应信号生成第一触控坐标数据，并当确定所述第一触控坐标数据来自操作区12时，根据来自操作区12的第一触控坐标数据生成调整指令。当所述触摸控制器12确定第一触控坐标数据来自于书写区11时，所述触摸控制器12直接将生成的来自书写区11的第一触控坐标数据发送至所述处理器20。具体的，所述触控传感器11的个数为多个，每一触控传感器11与一坐标对应，所述触摸控制器12接收触控感应信号后，确定产生所述触控感应信号的触控传感器11，并进一步根据所述触控传感器11对应的坐标而得出第一触控坐标数据。当所述第一触控坐标数据来自操作区12时，所述触摸控制器12还依据获取到的所述第一触控坐标数据生成对应的调整指令。其中，所述触摸控制器12进一步根据第一触控坐标数据中的各个坐标的位置变化来确 定包括触摸动作和触摸轨迹等信息的第一特定操作，并根据第一特定操作确定对应的调整指令。例如，所述触摸控制器12中预存有不同的第一特定操作与调整指令的对应关系，当所述触摸控制器12确定获取的第一触控坐标数据的集合来自于所述操作区12，且根据第一触控坐标数据确定出第一特定操作后，则进一步确定第一特定操作对应的调整指令。
可以理解，在本实施方式中，为防止手指、手掌等非笔触信号带来的误触控操作，可以将所述触摸板10的书写区11设置为屏蔽除所述手写笔200产生的触控感应信号之外的非笔触信号，从而提升笔触信号探测的精确性，优化触控书写体验。在其他实施方式中，所述触摸板10与所述书写区11对应的区域还可以包括电磁感应屏，所述电磁感应屏通过感测所述手写笔的电磁信号来生成第一触控坐标数据。
请再参阅图5，在一些实施例中，所述触摸板10还包括若干呈阵列排布的感应线圈101，若干感应线圈101分别对应一坐标且若干感应线圈101的属性均不同，其中，每个感应线圈101的属性包括每个感应线圈101的横截面积、匝数、感应强度等。当手写笔200与其中一个感应线圈101接触时，会感应到接触的感应线圈101的属性并依据该属性识别出对应的感应线圈101坐标而生成第二触控坐标数据。
如图3所示，在另一些实施方式中，所述手写板100还包括无线通信模块30。所述无线通信模块30与所述处理器20电连接，用于接收所述手写笔200所发出的第二触控坐标数据，所述处理器20用将所述第一触控坐标数据与所述第二触控坐标数据进行结合，并依据结合后的触控坐标数据生成书写笔迹，进而可以提高确定出的手写笔200在每个触控点的坐标的准确度，从而可以提高书写笔迹生成的准确率，优化书写笔迹。
在本实施方式中，所述无线通信模块30为低功耗蓝牙模块，所述无线通信模块30可以集成于所述处理器20内。在其它实施例中，无线通信模块30还可以是其它具有通讯功能的芯片，例如，WiFi芯片。所述无线通信模块30也可以为独立的通信模块。
请再参阅图6，图6为本申请一实施例公开的手写板100在书写时三维手写笔迹生成的示意图。所述无线通信模块30还用于将调整后的书写笔迹传输 给电子装置500，以触发所述电子装置500生成对应的三维手写笔迹(图中b所示)。其中，三维手写笔迹的颜色、粗细或笔迹类型不同于真实笔迹。
在本实施方式中，当用户用手写笔200在书写区11进行书写操作，且用户通过手指在操作区12进行滑动操作时，所述书写笔迹会随着用户在操作区12的滑行位置的变化而动态调整笔迹的粗细。例如，当用户在操作区12执行上滑操作时，该书写笔迹随上滑操作时用户手指在不同时刻上滑到操作区12的不同位置而逐渐调整笔迹的粗细。即，笔迹粗细与滑动方向以及用户手指在操作区12位置相关。
在另一些实施方式中，所述触摸板10还响应所述书写区11接收到的第二特定操作并生成修改指令。所述处理器20还用于依据所述修改指令对已生成的书写笔迹进行修改。当所生成的书写笔迹已形成图案时，所述触摸板10响应所述第二特定操作并生成所述修改指令，所述修改指令用于对已生成的所述图案进行修改。在本实施方式中，所述修改指令包括晕染修改指令或者上色修改指令。在其他实施方式中，所述修改指令还可以包括对已生成的书写笔迹进行涂抹或擦除等。
所述第二特定操作包括但不限于单指触摸所述书写区11上的书写笔迹并移动、双指触摸所述书写区11上的书写笔迹并移动等。每一修改指令对应的第二特定操作不同，例如，通过单指触摸已生成的书写笔迹并沿着笔迹的轨迹移动可以将已绘制的线条修改为晕染效果，通过双指触摸已生成的书写笔迹并在对应的图案区域移动可以将已绘制的图案上色。当然，每个修改指令所对应的第二特定操作可以依据具体的设计需求而进行设定，此处不做限定。
同样的，所述触摸板100包括触控传感器11和触摸控制器12时，所述触摸控制器12接收触控感应信号后，确定产生所述触控感应信号的触控传感器11，并进一步得出所述触控传感器11对应的坐标而得出第一触控坐标数据。所述触摸控制器12根据第一触控坐标数据确定触摸区域位于书写区11时，进一步根据第一触控坐标数据中的各个坐标的位置变化来确定包括触摸动作和触摸轨迹等信息的第二特定操作，并根据第二特定触摸操作确定对应的修改指令。
请再参阅图7，图7为本申请另一实施例公开的三维手写笔迹生成的示意 图。所述无线通信模块30还用于将修改后的书写笔迹传输给电子装置500，以触发所述电子装置500生成对应的三维手写笔迹(图中c所示)。其中，三维手写笔迹的颜色、粗细或笔迹类型不同于真实笔迹。
可以理解，所述手写板100也可以将所述书写笔迹及所述调整指令和/或修改指令实时传输给电子装置500，例如智能手机、平板电脑等，从而触发所述电子装置500依据所述调整指令和/或修改指令对所述书写笔迹进行调整和/修改，并生成对应的三维手写笔迹，进而可以实现在所述电子装置500的屏幕上实时显示所述三维手写笔迹，并可以实现对所述三维手写笔迹的数字化存储。
为了将所述用户手指输入的第二特定操作和所述手写笔200的书写操作进行区分，以避免将修改指令和生成书写笔迹进行混淆，在一些实施例中，所述触摸控制器12还用于判断所述触摸板10的书写区11产生所述第一触控坐标数据时的接触面积是否大于预设值，当所述接触面积大于预设值时，所述触摸控制器12确定当前为通过用户手指输入，所述触摸控制器12根据所述第一触控坐标数据生成所述修改指令。当所述接触面积不大于所述预设值时，所述触摸控制器12确定当前为通过手写笔200输入，所述触摸控制器12对生成的第一触控坐标数据不做处理，即直接将生成的第一触控坐标数据发送至所述处理器20。其中，所述预设值大于所述手写笔与所述触摸板10的接触的最大面积且小于用户手指与所述触摸板10的接触的最小面积。当然，在其他实施方式中，若所述手写笔200通过其他方式来产生触控信号，则该实施例可以省略。
其中，所述触摸控制器12可根据用户手指或手写笔200在单个触控点的触控坐标的数量确定得出所述手写笔200或用户手指与触摸板10的接触面积。
请再次参阅图3，在生成书写笔迹的过程中，为防止手指、手掌等非笔触信号带来的误触控操作，所述手写板100还包括开关40。所述开关40与所述处理器20电连接。所述处理器20还用于接收所述开关40响应触发产生的开关信号，当所述处理器20接收到第一开关信号时，所述处理器20才控制所述触摸板10响应所述书写区11所接收到的第二特定操作。在本实施方式中，所述第一开关信号为高电平信号，可以理解，在其他实施方式中，所述第一开关信号还可以是低电平信号。
具体地，在一个实施例中，开关40可以通过电阻接电源正极端，另一端接地，处理器20连接于开关40和电阻之间的节点，开关40处于导通或断开时，处理器20将分别接收到低、高电平信号，从而根据接收的信号来控制所述触摸板10通过所述书写区11响应所述用户手指输入的第二特定操作。其中，所述开关40可以是物理开关，例如，设置于手写板100的壳体侧边的按键开关或者拨动开关等。在其他实施方式中，所述开关40还可以是虚拟开关，例如，通过形成一触控图标并显示于所述触摸板10中，通过响应触摸而向所述处理器20发送不同的开关信号。
另外，在一些实施例中，在所述触摸板10还响应所述操作区12接收到的第三特定操作且所述触摸板10的书写区12未接收到书写操作时，根据所述第三特定操作生成控制指令。所述处理器20还依据所述控制指令控制所述手写板100执行相应的控制。
其中，所述第三特定操作包括但不限于单击所述操作区12、双击所述操作区域12、单指触摸所述操作区12并从所述操作区12的一侧滑向另一侧(即单指滑动)、双指触摸所述操作区12并从所述操作区12的一侧向另一侧滑动(即双指滑动)等。所述控制指令包括新建页码指令、保存页码指令、翻页指令或者建立通信连接(例如，与手写笔200或者电子装置500建立蓝牙连接)指令等。可以理解，每个控制指令与第三特定操作的对应关系在此不做限定，每个控制指令对应不同的第三特定操作，例如，单指向上滑动则对应向上翻页指令，单指向下滑动则对应向下翻页指令，双击对应建立通信连接指令等。
