步骤S101，建立透明书写层，并显示在所述电子终端的显示器中。
所述透明书写层为独立于所述电子终端100中的其它文件的电子文件的书写层。在一个实例中，所述透明书写层显示在所述电子终端的显示单元106的最上层。
步骤S102，接收电子笔在一数位板的书写区域进行的书写操作。所述电子笔直接或者间接与所述电子终端100通信连接。可选地，所述电子笔包括电磁笔芯。所述数位板的书写面上设有配置为识别所述电磁笔芯的磁性感应装置。所述数位板可采用电磁式感应原理，在光标定位及移动过程中，通过电磁感应来识别所述电子笔在所述数位板中执行的所述书写操作。所述数位板识别到所述电子笔在所述数位板的书写面中的书写操作后，将所述书写操作发送给所述电子终端100。
步骤S103，根据所述电子笔的书写操作在所述透明书写层中显示对应的书写内容。
在一种实施方式中，若所述显示单元106中显示有运行对象，则包括所述书写内容的透明书写层显示在所述运行对象上。当所述运行对象切换页面或者切换显示画面时，包括所述书写内容的透明书写层显示在切换后的运行对象的页面中。所述运行对象可以包括但不限于word文件、PPT文件、PDF文件、视频文件、动画文件、应用软件、网页和/或图片等。
在另一种实施方式中，若所述显示单元106中显示有运行对象，则包括所述书写内容的透明书写层显示在所述运行对象上。当所述运行对象切换页面或者切换显示画面时，所述包括所述书写内容的透明书写层随着所述运行对象的切换页面或者切换显示画面被清除。
再一种实施方式中，若所述显示单元106中显示有运行对象，则包括所述书写内容的透明书写层显示在所述运行对象上。当所述运行对象切换页面或者切换显示画面时，所述包括所述书写内容的透明书写层随着所述运行对象的切换页面或者切换显示画面被翻页。再次显示电子书写时显示的所述运行对象的页面时，恢复显示所述包括所述书写内容的透明书写层。
进一步地，所述电子终端100在接收到指定指令后，启动书写设置界面，所书写设置界面中包括多种处理工具；在接收到对所述书写设置界面中的处理工具进行操作时，使所述处理工具执行对应的操作。在一个实例中，所述电子终端100的显示单元106中可包括有所述书写设置界面隐藏/显示按钮。所述指定指令为在接收到点击所述隐藏/显示按钮后触发的所述指定指令，启动所述书写设置界面。在所述书写设置界面为显示状态时，接收到点击所述隐藏/显示按钮后触发隐藏所述书写设置界面。在另一个实例中，所述指定指令为所述数位板上的指定按钮被点击或按压后发送给所述电子终端100的指令。所述书写设置界面可以包括：书写字体设置工具、历史记录查看工具、截屏工具、电子白板工具、字体/线条颜色设置工具、橡皮擦工具及清屏工具等。例如，所述书写设置界面上包括所述历史记录查看工具的按钮，所述按钮接收到用户的点击、按压或借助其他设置执行的操作后，显示书写的历史数据。例如，所述书写设置界面上包括所述电子白板工具的按钮，该按钮接收到用户的点击、按压或借助其他设置执行的操作后，在显示屏上显示一可用于书写的电子白板。当然，用户使用完所述电子白板后，可以通过设置在屏幕的其它按钮隐藏所述电子白板，例如所述电子白板上的“×”、“-”按钮等，当然也可以在再次接受到用户操作所述电子白板工具的按钮时隐藏所述电子白板。进一步地，在接收到用户操作所述电子白板工具的按钮时，还可以显示一选择窗口，所述选择窗口包括：“历史白板”及“新建白板”等。所述电子终端100也可接收所述电子笔通过在所述数位板上的执行对应的操作后发送对所述书写设置界面中的各个功能模块的操作指令。当然，也可以通过鼠标等输入设备发送对所述书写设置界面中的各个功能模块的操作指令。
根据本实施例中的方法，通过建立新的透明书写层，将书写的内容显示在所述透明书写层中，使电子书写不用基于电子终端显示的文件进行书写，从而可以实现电子终端中不管显示什么类型的文件都能够书写。另外，通过电子笔在数位板上书写，然后传输给所述电子终端进行显示，以方便演讲人员或授课人员可以在距离电子终端的有限范围内的任意地方实现书写，为便演讲人员或授课人员提供方便。
第二实施例
请参阅图3，为本申请较佳实施例提供的电子书写方法的流程图。本实施例与第一实施例类似，其不同之处在于，还将将透明书写层进行存储，以方便再次打开对应文件页面时，将书写内容同步进行加载。下面将对图3所示的具体流程进行详细阐述。
步骤S201，建立透明书写层，并显示在所述电子终端的显示器中。
步骤S202，接收电子笔在一数位板的书写区域进行的书写操作。
步骤S203，根据所述电子笔的书写操作在所述透明书写层中显示对应的书写内容。
本实施例的步骤S201-S203与第一实施例中的步骤S101-S103类似，关于本实施例的 上述步骤可进一步地参考第一实施例，在此不再赘述。
步骤S204，将包括所述书写内容的所述透明书写层进行存储。
在一种实施例中，可将所述透明书写层与所述电子终端100中当前显示的文件页面进行合成，得到包括所述书写内容的文件页面。然后，将包括所述书写内容的文件页面替换原来的文件页面进行存储，以使电子终端100再次显示所述文件页面时，在所述文件页面中可显示包括所述书写内容的透明书写层。在一个实例中，若当前显示的文件页面为图片，则将包括所述书写内容的透明书写层与所述图片合成新的图片，替换原来的图片进行存储。当然，也可以将包括所述书写内容的透明书写层与所述图片合成新的图片另存储为不同于原来的图片的另一图片文件。进一步地，所述文件页面的格式可以是PPT格式、WORD格式、PDF格式、图片格式、视频格式等任意格式。
在另一种实施方式中，还可以通过对电子终端100的显示内容通过截屏的方式得到当前显示的文件页面，实现对包括所述书写内容的所述透明书写层的存储。
根据本实施例中的方法，通过将包括所述书写内容的所述透明书写层进行存储可以使演讲人员或者授课人员在下次讲述与前面讲述过的文件页面时不用重复书写，减少演讲人员或者授课人员的重复操作，提高用户体验。
在其它方法实施例中，所述电子书写方法还可包括：接收一数位板发送的切换操作模式的信号；根据所述切换操作模式的信号侦测所述电子笔执行的操作；根据所述电子笔的操作控制电子终端执行预设的指定操作。例如，所述数位板上设置有切换按钮，所述电子终端100侦测到所述切换按钮被点击或按压时，切换所述电子笔的操作模式，使所述电子笔控制所述电子终端100中的光标的移动及执行对应的操作，所述电子终端100进一步地执行所述光标对应的操作。所述对应的操作可包括鼠标控制显示界面中的光标执行的任意操作。通过切换操作模式，使演讲人员或者授课人员不仅可以远程书写，还能够远程控制电子终端100，使演讲人员或者授课人员在演讲中需要操作电子终端100时，不用走到电子终端100附近进行操作。
在其它方法实施例中，所述透明书写层可包括至少两页书写页面，所述电子书写方法还可包括：接收所述电子笔通过执行预设操作发送的对所述透明书写层执行的翻页指令；侦测到所述翻页指令后，执行所述翻页指令对应的翻页操作并显示翻页后对应的书写页面。本实施例中，所述电子笔可以通过所述数位板切换成鼠标功能，从而实现对所述透明书写层的翻页操作。通过将所述透明书写层设置成多页，可以使演讲人员或者授课人员的可书写的版面更广，提高用户体验。
