在群体沟通中，演示文稿作为沟通的焦点，除了进行信息显示之外，还有沟通过程中对演示内容的批注。智能交互平板中为提高批注效率，批注内容的显示通常单独渲染在顶层，也因此，要对演示文稿进行操作，需要先关闭批注界面再执行对演示文稿的操作，操作过程复杂，使用体验不佳。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例用于解释本申请，而非对本申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
实施例一
图1为本发明实施例一提供的一种演示文稿交互的方法的流程图。实施例中提供的演示文稿交互的方法可以由演示文稿交互的设备执行，该演示文稿交互的设备可以通过软件和/或硬件的方式实现，该演示文稿交互的设备可以是两个或多个物理实体构成，也可以是一个物理实体构成。例如，演示文稿交互的设备可以是手机、工业控制计算机等。
为了便于理解，实施例中以智能交互平板为实际载体，示例性描述书写轨迹调整的方法实施时调整目标选中、关联和调整响应的详细过程。其中，智能交互平板可以是通过触控技术对显示在显示平板上的内容进行操控和实现人机交互操作的一体化设备，其集成了投影机、电子白板、幕布、音响、电视机以及视频会议终端等一种或多种功能。
一般而言，智能交互平板包括至少一块显示屏。例如，图2中智能交互平板1配置有一块具有触摸功能的显示屏2，且该显示屏2可以是电容屏、电阻屏或者电磁屏。在一些实施例中，用户可以通过手指或触控笔触控显示屏2的方式实现触控操作，相应的，智能交互平板1检测触控位置，并根据触控位置进行响应，以实现触控功能。
典型的，智能交互平板安装有至少一种操作系统，其中，操作系统可以包括安卓系统、Linux系统及Windows系统。在一些实施例中，智能交互平板可以安装至少一个具有书写功能的应用程序。其中，该应用程序可以为操作系统自带的应用程序，同时，也安装有从第三方设备或者服务器中下载的应用程序。可选的，应用程序除具备书写功能外，还具有其他编辑功能，如插入表格、插入图片、插图图形、绘制表格、绘制图形等功能。其中，绘制得到的表格或图形为计算机绘制标准元素。计算机绘制标准元素可以理解为由智能交互平板绘制的印刷体标准元素，其区别于用户书写的元素。
在一些实施例中，参考图1，该演示文稿交互的方法可以包括：
步骤S101、在批注窗口获取触控操作的轨迹数据，所述批注窗口显示有演示文稿。
演示文稿作为教学、会议、展会等群体交互场景下的综合信息载体，可以综合呈现图片、文字、动画、视频、音频、网页链接等各种信息媒介。在图3所示的演示文稿中，其用于《蜀道难》(李白)的教学活动，在图3展示的演示文稿中，其至少包括图片、文字、音频、网页链接。通常来说，为根据群体交互场景的实际进度进行演示文稿中的信息展示，演示文稿不会设置为全自动播放，而是根据用户的操作在每个交互环节中进行对应的信息呈现，例如图3中的音频可能需要在教学活动开始时和教学活动的尾声分别进行播放，两次播放通过用户点击表示音频播放的喇叭形控件触发。
在演示文稿的实际展示过程中，除了对演示文稿本身内容的展示，在群体交互时还有基于内容展示的临时批注。在基于智能交互平板实现的信息展示过程中，批注通常需要通过状态切换进入，现有的批注和演示之间的切换，对应于前文所述从演示到批注的切换，从批注到演示的切换也是通过特定控件实现，一般来说，为不影响批注文稿的显示效果，特定控件常设置于智能交互平板的左下角和右下角，对于当前尺寸越来越大的智能交互平板来说，完成对特定控件的操作很多时候需要移步低头细看才能实现，本方案中，对触发位置没有约束，操作便捷流畅。
在本发明实施例中，当用户需要对打开的演示文稿(如PPT文档、word文档等)的当前显示页面进行批注时，可点击进入批注的按钮，在检测到用户的点击操作后，即切换进入批注状态，并在当前显示页面上覆盖全局透明的蒙层，以供用户进行批注。例如在图3所示的演示文稿页面中，只能对演示文稿本身的翻页、超链接、结束展示等演示文稿页面本身显示内容的变化进行操作，通过切换进入批注状态之后，可以基于用户操作在当前内容页面进行各种批注。当然，如果批注窗口通过第三方工具提供，也可以在打开演示文稿的同时默认进入批注状态。
在本发明实施例中，对于安卓系统，批注在一全局透明的蒙层中实现，全局透明的蒙层可为SurfaceView，其拥有独立的绘图表面，即不与其宿主窗口共享同一个绘图表面。由于拥有独立的绘图表面，因此SurfaceView的用户界面(User Interface，UI)就可以在一个独立的线程中进行绘制。又由于不会占用主线 程资源，SurfaceView一方面可以实现复杂而高效的UI，另一方面又不会导致用户输入得不到及时响应。需要说明的是，对于不同系统，蒙层可能有不同的名称或实现方法，但只要其实现原理或作用类似于安卓系统的SurfaceView，那么就在本申请的保护范围之内，例如通过carvas画布工具在课件层之上增加附加层实现蒙层。
此外，需要说明的是，所述演示文稿可以由智能交互平板上自带的相关软件打开并进行显示，也可以是在普通PC或笔迹本电脑上打开，并通过HDMI、VGA连接到智能交互平板后，显示在智能交互平板上，还可以是在普通PC或笔记本电脑上打开，再通过无线传屏传输到所述智能交互平板上进行显示等等。
步骤S102、根据所述轨迹数据匹配出所述触控操作的操作类型。
在对演示文稿进行批注的过程中，主要有两种工作模式，一种是书写模式，另一种是指令模式。在书写模式下，触控操作过程中对应滑动产生的轨迹数据大部分以书写轨迹的方式在显示屏上显示，用于批注演示文稿中的某个关键字或观点，例如图3中显示的演示文稿进入批注模式进行手写批注之后，对其中某些生僻字和生僻词进行批注，批注后的显示效果如图4所示。指令模式主要是对已有批注的二次处理(例如擦除)，以及可以用于控制演示文稿的简单变化(例如翻页)指令模式下触控操作多用于触发某个预设指令，触控过程中不会将轨迹数据解析为书写轨迹进行显示内容的增加。
不同批注模式下，通常的触控操作可能会带来不同的响应，但是作为批注状态下的两种工作模式，均有对演示文稿的内容进行直接操作的需求，基于此需求，书写模式和指令模式均应实现对演示文稿直接交互的快速切换。两种工作模式下，将某组轨迹数据匹配出为切换到演示文稿直接交互的预先设置可以相同，也可以不同。从简化用户操作的角度而言，两种工作模式下的切换方式最好设置为相同，例如检测到与特定滑动轨迹的轨迹数据特征相匹配的滑动轨迹时，确认需要对演示文稿进行操作，即确认为预设的演示切换指令。
在智能交互平板中，尤其在批注模式下，对触控操作最主要的反馈是将单指滑动反馈为书写轨迹进行显示。为避免与这一常规操作冲突，也避免减少误操作，在此，预设的演示切换指令的轨迹数据的特征设定弱化对轨迹形状的限定，强化对轨迹范围和特殊状态的持续时间的约束，由此，轨迹数据除了基础的触摸位置的检测，在该位置的变化规律的判断，例如坐标数据在一定半径范围内的持续时长，一种简单的方式，半径通过像素的个数进行描述，另外因为 触控操作变化周期相对比较短，时间可以以秒或者毫秒为单位进行计算。
对应的，所述触控操作在对应预设半径范围内计时达到对应的第一时间点时，确认为当前批注模式下的预设的演示切换指令。例如触控操作开始后触摸点的位置变化的半径控制在2个像素范围内，且持续时长达到2秒，则确认该触控操作对应为预设的演示切换指令。当然，实际根据设备的分辨率，触控检测的速度等因素差异，可以根据设备情况对半径和时长做调整。
步骤S103、若所述触控操作为预设的演示切换指令，置顶显示所述演示文稿。
如前文所述，批注模式下的操作在一全局透明的蒙层中实现，置顶显示演示文稿，根据显示层级架构可以有不同的实现。例如将演示文稿渲染到最顶层，显示屏接收到的触控操作直接作用在演示文稿；也可以是将用于批注的蒙层终止渲染，演示文稿自然置顶显示，显示屏接收到的触控操作同样直接作用在演示文稿，例如全局透明的蒙层SurfaceView，拥有独立的绘图表面，可以在一个独立的线程中进行绘制，在将用于批注的蒙层终止渲染时，后台终止该线程，蒙层即可取消，批注模式同时结束，无法再通过第三方应用进行批注输入。在后续的演示操作过程中，如果触控操作的坐标数据对应在演示文稿的显示画面上命中有演示控件，则该触控操作检测为有效的演示指令，演示文稿基于该演示控件进行画面更新；如果触控操作的坐标数据对应在演示文稿的显示画面上没有命中演示控件，则该触控操作检测为无效的演示指令，演示文稿维持原有显示状态。
步骤S104、接收对所述演示文稿的演示指令，显示所述演示文稿响应于该演示指令后的显示界面。
本方案重点关注演示文稿在不同显示模式下的切换机制，演示文稿的演示操作(例如向前翻页、向后翻页、打开插入文件、打开超链接)等是演示文稿的通用操作，在此不做赘述。另外需要说明的是，不管将演示文稿置顶渲染还是终止全局透明的蒙层的渲染，批注痕迹所依附的基础都已经不再顶层，也就是不管是基于对哪个对象的渲染变化，在执行到步骤S103时，显示画面中已经没有了批注痕迹的存在。
上述，通过在批注窗口获取触控操作的轨迹数据，所述批注窗口显示有演示文稿；根据所述轨迹数据匹配出所述触控操作的操作类型；若所述触控操作为预设的演示切换指令，置顶显示所述演示文稿；接收对所述演示文稿的演示 指令，显示所述演示文稿响应于该演示指令后的显示界面。在批注模式下对触摸轨迹的检测，如果检测结果匹配出对应的触控操作为预设的演示切换指令，则将演示文稿置顶显示，给用户提供了便捷的切换体验。
实施例二
图5为本发明实施例二提供的一种演示文稿交互的方法的流程图。本实施例是在上述实施例的基础上进行改动。
参考图5，本实施例提供的演示文稿交互的方法可以包括：
步骤S201、在批注窗口获取触控操作的轨迹数据，所述批注窗口显示有演示文稿。
在打开演示文稿之后，可以通过在设定位置布局的批注触发控件，或者接收带有控制功能的智能笔发送的控制指令等方式进入批注模式。在批注模式下，通过在当前所显示的视图上渲染用于批注的蒙层，并监听用户触发的批注事件，以及根据批注事件更新蒙层的显示内容。最终实现模式切换的预设的演示切换指令也在该蒙层中检测确认。
步骤S202、从所述起始时间开始计时，并计算所述坐标数据的移动距离。
步骤S203、在计时达到第二时间点时，开始突出显示所述触控操作对应的触摸点位置。
步骤S204、若在计时达到第一时间点的计时过程中，所述移动距离在预设距离范围内，则在计时达到第一时间点时确认所述触控操作为预设的演示切换指令。
步骤S202-S204是一个持续同时判断的过程，在此作为一个整体进行阐述。
批注模式下的两种工作模式中，书写模式中检测到触控操作主要有三种响应，第一种是新增书写轨迹；第二种是触发触控操作命中的功能控件，例如切换到指令模式；第三种是可能的无效操作，例如同时检测到七个触控点的运动。指令模式下检测到触控操作主要有两种响应，第一种是触发触控操作命中的指令空间，例如选中某个颜色；第二种是可能的无效操作，例如单指连续滑动。综合两种工作模式的响应机制，可以选择两种工作模式中均未占用的触控操作作为预设的演示切换指令这一操作类型的实现。基于前一实施例中对预设半径和持续时长的方案，描述计时过程的操作。在一些实施例中，在检测到触控操作后，即可获得该触控操作的起始的坐标数据和起始时间，从起始时间开始计 时，计时是否归零的判断依据是坐标数据的判断状态，如果根据坐标数据的变化计算出移动距离超出预设范围，计时归零。也就是说步骤S203中的计时不是一定能达到第二时间点，如果触控操作移动超出范围，计时会取消。在时间点的设置上，在计时达到第一时间点的设定比例时，设定为第二时间点；在这两个时间点之间，突出显示触控操作对应的触摸点位置，例如设定的计时的第一时间点是2秒，第二时间点是1秒，那么从起始时间开始计时达到1秒(第二时间点)的时候，直到计时达到2秒(第一时间点)，这两个时间点之间突出显示触控操作对应的触摸点位置。
在一些实施例中，从显示细节上，触摸点位置在第二时间点和第一时间点的显示效果不同；显示效果的不同可以是突变实现，也可以通过渐变实现，其中通过渐变实现的显示效果变化可以为用户提供更清楚的模式切换指向和后续操作的准备，用户的操作准度更高。基于该方案可以在计时达到第一时间点时直接确认为预设的演示切换指令。
步骤S205、在所述第一时间点显示选择窗口，所述选择窗口用于显示操作类型提醒，并接收触控反馈。
除了以上突出显示，还可以提供确认提醒。在收到基于确认提醒的反馈之后再确认为预设的演示切换指令，确认提醒可以通过显示选择窗口实现，选择窗口在触摸点位置的设定半径内弹出，选择窗口通过蒙层实现，在选择窗口中显示有操作类型的提醒，尤其是针对本方案中预设的演示切换指令的确认提醒。
在选择窗口中可以在一个窗口中提供两个反馈控件，其中一个反馈控件接收到的反馈信息作为确认预设的演示切换指令，另一反馈控件接收到的反馈信息作为否认预设的演示切换指令，在这种反馈控件布局方式中，可以停止对选择窗口之外区域的所有触控操作的响应；也可以将选择窗口整体作为一个反馈控件，该反馈控件接收到的反馈信息作为确认预设的演示切换指令，将选择窗口之外的区域作为另一个反馈控件，该反馈控件接收到的反馈信息作为否认预设的演示切换指令。在实施过程中，在反馈控件检测到的任何触控操作均视为接收到反馈信息。选择窗口临近触控点位置弹出，两次操作之间的衔接方便，操作简洁。
请参考图6-图9，本实施例中结合图6-图9对步骤S202-S205中预设的演示切换指令的确认过程做示例性综合描述。在图4中，已经在批注模式下完成了批注内容的输入，主要是对一个词和两个字的批注。基于图4中的显示画面(手 型不属于显示画面，仅用于示意触控操作)，如图6所示，有新的触控操作发生，在本实施例中，需要获取到触控操作的坐标数据和时间状态。如果图6中的触控操作对应的坐标数据持续变化，那么应该在图6中不断生成新的书写轨迹作为新增批注内容。
如果图6中的触控操作对应的坐标数据在两个像素范围内停留的计时达到1秒(第二时间点)，可以突出显示发生停留的触摸点位置，计时达到1秒时的画面状态如图7所示。
随着计时继续进行，如果在计时达到2秒(第一时间点)前坐标数据离开两个像素范围内，计时归零，触摸点位置的突出显示取消，恢复到图6所示的状态，并根据坐标数据更新书写轨迹；如果在计时达到2秒(第一时间点)时坐标数据一直在两个像素范围内，则显示选择窗口，此时的画面状态如图9所示，此时触摸点位置的突出显示可以直接取消，也可以保留到触摸操作(即，所述触控操作)的接触状态结束。
在以上处理过程中，用户可以根据突出显示的效果确认当前的选择进度，并且可以随时放弃当前操作并切换到初始状态。
在图9所示的状态中，根据反馈控件的不同布局方式，可以根据检测到的后续触控操作确认是否进入选择模式，如果进入选择模式，则确认关于坐标数据和静态持续时长的匹配成功，即确认触控操作的操作类型为预设的演示切换指令，需要选择演示文稿中的操作控件进行演示内容的变化，否则计时归零，重新开始基于坐标数据范围的计时。最后基于反馈控件的方式可以有效避免误操作，一次随机触控即可取消误操作。
需要说明的是，从第二时间点到第一时间点，触摸点位置的高亮显示有一个持续变化的过程，在图8相对于图7呈现的是高亮显示范围扩大，可以约束范围扩大的最大比例为0.2，例如第一时间点的高亮显示区域的半径是第二时间点的半径的1.2倍，这一变化过程持续到计时归零。当然，可以有颜色过渡、灰度过渡、高亮显示范围缩小等方式。
步骤S206、若所述触控操作为预设的演示切换指令，所述演示文稿置顶显示。
在匹配到预设的演示切换指令之后，置顶显示演示文稿，在置顶显示的演示文稿中，所有的触控操作直接作用于演示文稿，如图10所示，如果后续的触控操作命中音频控件，则开始播放演示文稿中插入的音频文件，如果后续的触 控操作命中超链接，则跳转到超链接对应的页面。
在批注模式下，对触控操作的所有可能响应有多种，除了预设的演示切换指令，还有在对应工作模式下的其它响应过程。
在各个工作模式下的响应过程中，需要说明指令模式下的滑动操作，如果触控操作为指令模式下的滑动操作，可以突出显示所述滑动操作的触摸点位置。这里所说的突出显示只是显示触摸点位置，触摸点位置发生变化之后，原来触摸位置恢复到触摸之前的显示。在指令模式下，除了前文所述取消触摸点的突出显示，还可以是滑动操作的触摸点位置的显示方式与第二时间点触摸点位置的突出显示方式(图7所示)相同。也就是说在指令模式下，从滑动状态到第二时间点，触摸点位置的显示方式不变。
若所述触控操作为书写模式下的书写操作，显示所述触控操作对应的书写轨迹。
若所述触控操作为指令模式下的控制操作，响应所述触控操作命中的批注控件。
书写操作和控制操作是批注中常规操作，需要说明的是，书写模式下的书写操作和指令模式下的滑动操作，底层的轨迹数据处理过程相同，不同在于二者的显示效果不同，尤其是第二时间点之前的显示效果不同。
步骤S207、接收到批注触发指令，进入书写模式或指令模式。
批注触发指令可以是智能交互平板上的控件检测接收，也可以通过接收智能笔发送的控制信号确认。对于返回机制，可以在批注过程中识别每页批注内容对应显示的图像数据，将整个演示过程中形成的批注内容以页为单位进行保存，并建立每页批注内容与对应的图像数据之间的关联关系。当演示文稿置顶显示时，批注内容停止显示，但是并不删除，返回到批注模式之后，可以根据当前演示文稿的显示的图像数据以及在先建立的每页批注内容与对应的图像数据之间的关联关系，直接获取当前显示的图像数据对应的批注内容并恢复对应的批注内容显示。
