具体实施方式
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。
本申请的说明书和权利要求书中的术语“包括”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参阅图1，图1为本申请一实施例中的手写输入装置100的示意图。所述手写输入装置100用于与一外部设备200通信连接。具体地，所述手写输入装置100包括手写板1、手写笔2以及写字本3。所述手写板1具有表面F1。所述写字本3设置于所述手写板1的表面F1上。所述写字本3包括多个层叠设置的纸张31。所述多个纸张31的一边被固定在所述手写板1的表面F1上，且所述多个纸张31能够绕该边翻动。所述手写笔2用于在放置于所述手写板1上的写字本3的纸张31上进行书写。所述手写板1用于感测所述手写笔2在放置于所述手写板1上的写字本3的纸张31上进行书写时的触控轨迹，并根据触控轨迹识别出对应的书写内容数据，及将该书写内容数据发送给外部设备200以使所述外部设备200显示相应的书写内容。其中，所述手写笔2为具有油墨等墨水的触控笔，手写笔2在放置于手写板1上的写字本3的所述纸张31上进行书写时，在纸张31上形成实际的书写字迹的同时，在手写板1上形成与该实际笔迹相对应的电子笔迹。
请一并参阅图2，图2为所述手写板1的结构框图。所述手写板1包括处理器11和感应模组13。感应模组13与处理器11电性连接。感应模组13设置在每个纸张31翻动过程中均会经过的位置上，每一纸张31对应感应模组13的位置上设置有一纸张识别码131(如图3所示)。当纸张31翻动时，所述感应模组13感应相应纸张31的纸张识别码131并将感测数据发送给处理器11，所述处理器11通过所述纸张识别码131确定当前外露的纸张31的页码。其中，当前外露的纸张31是指当前朝向用户的未被其他纸张31覆盖的纸张31。可以理解，当前外露的纸张31可为一张纸或两张纸。若最后翻动的纸张31是写字本3的第一页或最后一页，则该当前外露的纸张31的页码为一个；否则，该当前外露的纸张31的页码 为两个，包括最后翻动的纸张的一个页码及与该最后翻动的纸张相邻的一张纸的一个页码。
从而，本申请中，无论一张纸张31翻动，还是多张纸张31同时翻动，都可以准确地确定当前外露的纸张31的页码，页面定位更准确。
具体地，在一实施例中，所述纸张识别码131设置于每页纸张31的厚度方向上。
具体地，在一实施例中，当纸张31翻动时，所述感应模组13感应每个纸张31的翻动并产生感应信号。所述处理器11接收所述感应信号并根据所述感应信号确定最后翻动的纸张31，且根据最后翻动的纸张3的纸张识别码131及其翻动方向确定当前外露的纸张31的页码。
例如，当以从左翻动到右的第一方向翻动n张纸张31时，感应模组13感应每个纸张31的翻动并产生感应信号，若预设时间段内，感应模组13没有产生新的感应信号时，处理器11确定当前最后接收到的感应信号对应的纸张31即为最后翻动的纸张31。
具体地，在一实施例中，当至少一张纸张31翻动时，所述感应模组13依次扫描每一翻动的纸张31的纸张识别码131并依次产生感应信号。所述处理器11依次接收上述感应信号，并处理上述感应信号中的第一接收的感应信号和最后接收的感应信号，以识别所述至少一张翻动的纸张31中的最先翻动和最后翻动的纸张31的页数，且在所述至少一张纸张31翻动结束时根据最后翻动的纸张31的页数及其翻动方向确定当前外露的纸张31的页码。
可理解，在另一实施例中，当至少一张纸张31翻动时，所述感应模组13依次扫描所述至少一张纸张31中每一纸张31的纸张识别码131并依次产生感应信号。所述处理器11依次接收所述感应模组13扫描每一纸张31的纸张识别码131时产生的感应信号，并依次处理上述感应信号，以识别所述每一翻动纸张31的页数，并在该纸张31翻动结束时确定最后翻动的纸张31，且根据所述最后翻动的纸张的页数及其翻动方向确定当前外露的纸张31的页码。
举例说明，在一实施例中，最后翻动的纸张31的页数是3，则当前外露的纸张31的页码可能是4和5，或者6和7，如果最后翻动的纸张31的翻动方向是向后翻页，则确定当前外露的纸张31的页码为4和5。如果最后翻动 的纸张31的翻动方向是向前翻页，则确定当前外露的纸张31的页码为6和7。
在一实施例中，所述手写板1还包括存储器14和通信单元15。所述存储器14中存储有电子文档。所述通信单元15与所述处理器11电性连接。所述处理器11在确定好所述当前外露的纸张31的页码时，还判断所述存储器14中是否存储与所述当前外露的纸张31的页码对应的电子文档。如果没有，则新建空白电子文档，如果有，则从所述存储器14中调取该页码对应的电子文档，并将所述空白文档或者所述电子文档通过所述通信单元15发送给外部设备200，以供所述外部设备200执行对应的显示，例如，显示新建空白页面或显示对应的电子文档等。
在一实施例中，所述手写板1的表面F1上设置有活页夹12，所述写字本3具有一装订边33。所述写字本3的装订边33通过所述活页夹12装订在所述手写板1上，所述写字本3的纸张31能够绕所述活页夹12的轴线翻转而翻动到上一页或下一页。所述纸张31具有邻近所述活页夹12的边角区域311。所述感应模组13设置在所述手写板1的表面F1上并与所述活页夹12的末端和所述边角区域311相邻，每个纸张31的纸张识别码131设置在其对应的所述边角区域311内。
在一实施例中，所述感应模组13设置于手写板1表面的与所述装订边33垂直的侧边上并位于所述活页夹12的一端，所述纸张31的纸张识别码131设置在所述感应模组13的侦测范围内。从而，所述纸张31在整个翻动过程中，所述纸张31的纸张识别码131均经过所述感应模组13。从而，所述多个纸张31在翻动的过程中，所述感应模组13能够感应并产生感应信号。
在一实施例中，所述手写板1包括两个封面部14和两组感应器阵列16。所述两组感应器阵列16分别设置在所述两个封面部14相对的表面上。若干纸张31呈摊开状，一部分放置与其中一个感应器阵列16上，另一部分放置于另一感应器阵列16上。所述两组感应器阵列16用于感应通过手写笔2在位于其中一个感应器阵列16上的纸张31书写时的触控轨迹，并根据触控轨迹得出对应的书写内容数据，并且所述书写内容数据被发送给外部设备200以使所述外部设备200显示相应的书写内容。其中，当确定呈现在用户面前的纸张31的页码后，所述处理器11根据所述手写笔2在所述手写板1的感应器阵列16上 的书写位置，以及当前呈现在用户面前的纸张31的页码来确定当前书写纸张的页码。
在一实施例中，请一并参考图3，每个封面部14具有书写区域141和边缘区域143。所述边缘区域143呈“凹”状，并围绕所述书写区域141设置。所述感应器阵列16设置在所述书写区域141内。所述处理器11设置在所述边缘区域143上并与所述感应器阵列16电性连接。
在一实施例中，请再次参考图1，所述边缘区域143上设置有充电数据接口1431和视频接口1433。所述充电数据接口1431和视频接口1433均与所述处理器11电性连接。其中，所述充电数据接口1431用于充电连接或者数据传输连接。所述视频接口1433用于视频数据的传输连接。
在一实施例中，所述手写板1包括连接部17。所述连接部17位于所述两个封面部14之间，并像书脊一样连接所述两个封面部14，从而使手写板1形成一呈书状的手写输入装置100。所述感应模组13设置在所述连接部17的一端且邻近所述活页夹12的位置上。
在一实施例中，所述两个封面部14的长宽尺寸都相等。所述连接部17位于所述两个封面部14之间。也就是说，所述连接部17位于所述两个封面部14的对称轴线上。所述连接部17的两端延伸至与所述封面部14的两端相平齐的位置上。
在一实施例中，所述活页夹12设置在所述连接部17上，且所述活页夹12的延伸方向与所述连接部17的长度方向一致；而且，所述活页夹12在长度方向上比所述连接部17短，从而，所述连接部17位于所述活页夹12端部的位置上形成一收容空间。所述感应模组13设置在所述收容空间内并邻近所述活页夹12的端部。
可理解，在其它实施例中，所述感应模组13和所述纸张识别码131还可以设置在其它适合的位置上，并不局限于上述已经列举出的位置，只要能够定位所述写字本3的当前页面即可。
在一实施例中，请一并参考图3和图4，所述纸张识别码131由多个识别点1311间隔排列而成。每一纸张识别码131包括多个间隔开的识别点1311，且每一纸张识别码131所包含的识别点1311数量、识别点1311的宽度以及识 别点1311之间的间隔宽度不同并具有唯一性，且与所述纸张31的页数一一对应。从而，每个纸张31上的纸张识别码131都是唯一的识别码，并且，该识别码与该纸张31的页数一一对应，再结合最后翻动纸张31的翻动方向，因而，当前外露的纸张31的页码能够准确定位，而不会因为一次翻动多张纸张31而无法识别翻页页数。
具体地，所述识别点1311具有将所接收到的光线反射回去的特性，所述感应模组13接收经所述多个识别点1311反射后的光线数据，并产生感应信号。所述处理器11根据所述感应信号识别所述纸张识别码131，并从存储在所述存储器14中的数据库中调出预设纸张识别码与纸张页数的对应关系表，以确定与所述纸张识别码131对应的页数，从而能够结合最后翻动的纸张31的页数及其翻动方向确定所述当前外露的纸张31的页码。
具体地，在该实施例中，所述识别点1311为荧光印刷油墨点。可理解，在其它实施例中，所述识别点1311为采用其它材料制成的具有光反射功能的油墨点。
进一步地，请一并参考图5、图6和图7，所述感应模组13具有第一感应区域133和第二感应区域134。所述第一感应区域133和第二感应区域134位于所述手写板1上的当纸张31翻动时会先后经过的两个位置，所述处理器11在接收所述第一感应区域133和第二感应区域134产生的感应信号后，确定第一感应区域133和第二感应区域134的感应信号为在预设时间内产生时，根据接收到所述第一感应区域133和第二感应区域134单元的感应信号的先后顺序确定所述写字本3的纸张31的翻动方向。
进一步地，所述处理器11在先接收到所述第一感应区域133的感应信号，然后接收到第二感应区域134的感应信号时，确定所述写字本3的纸张31的翻动方向为向后翻页。换句话说，所述向后翻页是指将所述纸张31从位于左侧的封面部14上方的位置朝向位于右侧的封面部14的上方的位置翻动。所述处理器11在先接收到所述第二感应区域134的感应信号，然后接收到第一感应区域133的感应信号时，确定所述写字本3的纸张31的翻动方向为向前翻页。换句话说，所述向前翻页是指将所述纸张31从位于右侧的封面部14上方的位置朝向位于左侧的封面部14的上方的位置翻动。
进一步地，所述第一感应区域133以及所述第二感应区域134并排设置。
其中，在一些实施例中，处理器11为在接收第一感应区域133及第二感应区域134产生的感应信号后，还判断接收第一感应区域133及第二感应区域134产生的感应信号的间隔是否在预设时间(例如2秒内)内，当确定接收第一感应区域133及第二感应区域134产生的感应信号的间隔在预设时间内时，才根据接收到第一感应区域133及第二感应区域134的感应信号的先后顺序确定写字本3的纸张31的翻动方向。从而，通过确定第一感应区域133及第二感应区域134产生的感应信号为在预设时间内先后接收到的，避免误判断。
在一些实施例中，处理器11在先接收到第一感应区域133的感应信号，然后接收到第二感应区域134的感应信号时，确定写字本3的纸张31的翻动方向为向后翻页(即翻动到后一页)。处理器11在先接收到第二感应区域134的感应信号，然后接收到第一感应区域133的感应信号时，确定写字本3的纸张31的翻动方向为向前翻页(即翻动到前一页)。
当纸张31的翻动方向为向后翻页(即翻动到后一页)时，纸张31是从贴近手写板1的表面F1的位置朝着远离手写板1的表面F1运动，将会先经过第一感应区域133，再经过第二感应区域134。而当纸张31的翻动方向为向前翻页(即翻动到前一页)时，纸张31是从远离手写板1的表面F1的位置朝着贴近手写板1的表面F1运动，将会先经过第二感应区域134，再经过第一感应区域133。
从而，如前，处理器11在先接收到第一感应区域133的感应信号，然后接收到第二感应区域134的感应信号时，确定写字本3的纸张31的翻动方向为向后翻页。处理器11在先接收到第二感应区域134的感应信号，然后接收到第一感应区域133的感应信号时，确定写字本3的纸张31的翻动方向为向前翻页。
可理解，本实施例中，所述感应模组13为红外光传感器，所述第一感应区域133和所述第二感应区域134为所述红外光传感器的两个并排设置的分区。可理解，在其它实施例中，所述第一感应区域133和所述第二感应区域134为并排设置的独立红外光传感器。
在另一实施例中，所述感应模组13为颜色识别传感器，所述纸张识别码 131为颜色标识点。可理解，所述写字本3的每一纸张31的颜色标识点的颜色值均不相同。所述存储器14中存储颜色值与纸张页数的对应关系。所述感应模组13感应所述纸张31的纸张识别码131并产生包含纸张颜色值的感应信号。所述处理器11接收所述感应信号并根据所述感应信号的纸张颜色值确定所述纸张31的页数。所述第一感应区域133和所述第二感应区域134为同一颜色识别传感器的两个并排设置的分区。可理解，在其它实施例中，所述第一感应区域133和所述第二感应区域134为并排设置的独立的颜色识别传感器。
在又一实施例中，所述感应模组13包括方向感应单元和页码识别单元。其中，所述方向感应单元可以是红外光传感器或者颜色识别传感器。所述方向感应单元用于感应纸张31的翻动方向。所述页码识别单元可以是磁感应传感器。所述纸张识别码131为磁粉标识点组合。可理解，所述写字本3的每一纸张31的磁粉标识点的宽度和标识点之间的间隔宽度均不相同。所述页码识别单元用于识别所述翻动纸张31的纸张识别码131。所述存储器14中存储预设纸张识别码与纸张页数的对应关系。所述感应模组13感应所述纸张31的纸张识别码131并产生感应信号。所述处理器11接收所述感应信号并根据所述感应信号确定与所述纸张识别码131对应的页数，从而能够结合当前外露的纸张31的页数和所述当前外露的纸张31的翻动方向确定所述当前外露的纸张31的页码。
可理解，在其它实施例中，若干纸张31堆叠形成的写字本被翻开时，具有位于其中一组感应器阵列16上方的第一侧和位于另一组感应器阵列16上方的第二侧，所述感应模组13为邻近所述第一侧或者所述第二侧设置的感应模组，所述感应模组13的识别面积足够大，即可以一次把该第一侧或该第二侧所有纸张31的纸张识别码131全部识别出来，因此，只要识别出该第一侧或该第二侧的所有纸张的纸张识别码131，即可得知该侧最上面的纸张31的页码。即，当纸张31翻动时，所述处理器11通过所述感应模组13感应当前外露的纸张31的纸张识别码131而确定当前外露的纸张31的页码。
可理解，在其它实施例中，所述感应模组13是同时邻近所述第一侧和所述第二侧的感应模组13，所述感应模组13可识别翻页方向，但是所有纸张31的纸张识别码131可以相同，即通过感应模组13来识别每次翻过的纸张31 的页数及翻页方向来确定最终位于最上方的纸张31的页码。即，当纸张31翻动时，所述处理器11通过所述感应模组13感应所翻动的纸张31的纸张识别码131而确定所翻动的纸张31的页数，再根据所翻动的纸张31的页数确定当前外露的纸张31的页码。
本申请中，通过将感应模组13设置在手写板1上的当纸张31翻动过程中经过的位置上，当至少一张纸张31翻动时，则会经过感应模组13，处理器11则通过感应模组13产生的感应信号确定当前外露的纸张31的页码，页面定位更准确。
其中，处理器11可为中央处理器、单片机、数字信号处理器、微控制器等。存储器14可为固态存储器、存储卡等。通信单元15可为蓝牙模组、WIFI模组、GPRS通信模组等无线模组，也可为USB接口、火线接口等有线接口单元。
其中，本申请中的第一感应区域133及第二感应区域134并非特指某一感应模组，而是为了便于区分而以第一、第二进行命名。
其中，外部设备200可为手机、平板电脑等装置，并安装有与手写输入装置100配套的应用软件(APP)。

进一步具体地，在先接收到所述第一感应区域133的感应信号，然后接收到第二感应区域134的感应信号时，确定所述写字本3的纸张31的翻动方向为向后翻页；以及在先接收到所述第二感应区域134的感应信号，然后接收到第一感应区域133的感应信号时，确定所述写字本3的纸张31的翻动方向为 向前翻页。
进一步具体地，当至少一张纸张31翻动时，所述感应模组13依次扫描所述至少一张纸张31中每一纸张31的纸张识别码131并依次产生感应信号；依次接收上述感应信号，并处理上述感应信号中的第一接收的感应信号和最后接收的感应信号，以识别所述至少一张翻动的纸张31中的最先翻动和最后翻动的纸张31的页数，且在所述至少一张纸张31翻动结束时根据最后翻动的纸张31的页数及其翻动方向确定当前外露的纸张31的页码。
在另一实施例中，依次接收所述感应模组13扫描每一纸张31的纸张识别码131时产生的感应信号，并依次处理上述感应信号，以识别所述每一翻动纸张31的页数，并在该纸张31翻动结束时确定最后翻动的纸张31，且根据最后翻动的纸张31的页数及其翻动方向确定当前外露的纸张31的页码。
进一步地，所述页面定位方法还包括：
步骤S830：在确定当前外露的纸张31的页码后，调取该页码对应的空白电子文档或者电子文档发送至所述外部设备200以供显示。
具体地，在确定当前外露的纸张31的当前页码后，判断所述页码是否与有对应的电子文档存储，如果没有，则新建空白电子文档，如果有，则从手写板1的存储器14中调取该页码对应的电子文档，并将所述空白电子文档或者所述电子文档发送至所述外部设备200以供显示。
进一步地，在一实施例中，所述页面定位方法还包括：
步骤S840：所述手写板1感应所述手写笔2在其书写区域141输入预设操作时，控制所述手写板1进入历史回顾模式，并显示要对外输出显示内容的写字本页码选择项。
进一步地，所述页面定位方法还包括：
