图2示出了本发明实施例的多用户会议系统的应用示意图。如图2所示， 可将边框状的红外设备110置于书写承载介质130(例如白板等)上，利用辅助设备150(例如手机等)，将红外设备110与云服务器120通信连接。红外设备110将获取的用户在书写承载介质130上操作书写物体生成的坐标信息发送给云服务器120。云服务器120实时记录并存储红外设备110中的数据处理模块113生成的综合数据。云服务器120与参与会议的多个终端140相关联，云服务器120将当前的多用户会议系统100中的综合数据发送到指定终端140。终端140可以通过终端140上特定的软件，例如微信、邮件或应用客户端APP等接收会议内容。多个终端140通过特定的软件，绑定指定多用户会议系统的云服务器120，接收并解析综合数据成为坐标信息、尺寸大小信息等，还原功能属性信息，并按坐标信息对应的时间信息再现会议的书写过程。
可选地，在本发明实施例中，该网络设置模块111基于蓝牙技术或红外技术，将该红外设备110与该辅助设备通信连接，通过该辅助设备上的应用客户端提供的设置页面进行设置，以使得该红外设备110连接至该云服务器120或更改该红外设备110的网络设置。
具体而言，由于本发明实施例的红外设备110不具有显示屏，因此可以配合如图2所示的辅助设备150，通过该辅助设备150上的应用客户端提供的设置页面，设置红外设备110的网络设置，使红外设备110连接至该云服务器120。后续还可以通过辅助设备150更改该红外设备110的网络设置。其中，网络设置模块111可以基于蓝牙技术或红外技术，将该红外设备110与该辅助设备150通信连接。此外，还可以通过USB运行相应的程序为红外设备110进行网络设置，本发明实施例对此不作限定。
可选地，在本发明实施例中，该红外设备110还可以包括本地存储模块，该本地存储模块用于实时记录并存储当前该书写承载介质上对应的该综合数据。
具体而言，由于本发明实施例的红外设备110不具有显示屏，为了方便用户管理会议，可以在红外设备110中设置本地存储模块，以实时记录并存储当前书写承载介质的一页对应的综合数据。由此，当发生突然断电或其它突发情况时，可以对本地存储模块中存储的数据进行处理，以恢复正常的会议数据。该数据处理模块具体可以用于在该书写承载介质的一页书写完成时，将该本地存储模块存储的该书写承载介质的一页对应的该综合数据发送 至该云服务器。每当书写承载介质的一页书写完成时，数据处理模块可以将本地存储模块中存储的该页的综合数据进行处理，生成该页的会议文件，发送给云服务器120.
可选地，在本发明实施例中，在该红外线位置检测模块的电源关闭时，该数据处理模块113将该本地存储模块存储的该综合数据发送至该云服务器120，并且该本地存储模块存储的该综合数据不清空。
具体而言，通常而言，设备断电时，设备的内存做清空处理。而本发明实施例中，当红外线位置检测模块112的电源关闭时，即红外线位置检测模块112断电时，数据处理模块113将本地存储模块存储的综合数据(断电当时书写承载介质上内容对应的数据)发送至云服务器120。同时，本地存储模块存储的综合数据不进行清空，而是等待红外线位置检测模块112重新上电后继续处理。由此，可以保证突然断电时，书写内容不丢失。
可选地，在本发明实施例中，该数据处理模块113还用于检测当前获取的坐标是否与该本地存储模块内存储的综合数据中的坐标重合，在该当前获取的坐标与该本地存储模块中存储的综合数据中的坐标重合时，该数据处理模块113将本地存储模块中存储的综合数据发送至该云服务器120，并删除该本地存储模块中已发送至该云服务器120的综合数据。
具体而言，在红外线位置检测模块112断电后又上电时，数据处理模块113用于检测当前红外线位置检测模块112获取的坐标是否与该本地存储模块内存储的综合数据中的坐标重合。如果重合，则说明断电期间书写承载介质的内容可能被擦除了，此时，数据处理模块113将本地存储模块中存储的综合数据发送至该云服务器120，并删除本地存储模块中已发送至云服务器120的综合数据，即将新书写的内容认为是新的一页书写内容。换而言之，当数据处理模块113发现目前的书写是在已有书写内容的区域开始一定规则的书写，导致内容重合时，将之前存储在本地存储模块中的数据存储到云服务器120，清空本地存储模块中的数据，将新的内容作为新建的一页进行存储。因此，上述实施例考虑设备电源的开关对数据存储的影响，保证电源开关时书写内容的完整性。
应理解，本发明实施例中，数据处理模块113将本地存储模块中存储的综合数据发送至该云服务器120可以是实时发送并由云服务器120实时存储的，也可以是本地存储模块存储书写承载介质一页的综合数据后，再向云服 务器120发送并由云服务器120存储的。不同的发送存储方式使得数据处理模块113和云服务器120的处理过程不同，本发明实施例对此不进行赘述。
可选地，在本发明实施例中，该综合数据中包括用于指示该红外设备100的物理标识，该云服务器120根据该物理标识，为该红外设备110分配对应的存储空间，并将该综合数据存储在该存储空间中。
具体而言，当数据处理模块113检测并接收到红外线位置检测模块112生成的坐标信息时，将坐标信息和指示该红外设备110的物理标识进行融合，形成综合数据。数据处理模块113马上连接并将综合数据发送至云服务器120。云服务器120在接收到综合数据时，首先从中提取红外设备110唯一对应的物理标识(物理ID)，并为红外设备110分配唯一对应的存储空间。
可选地，在本发明实施例中，该多用户会议系统100为该会议分配会议标识，该终端通过应用客户端输入该会议标识接入该会议。
具体而言，多用户会议系统100为该会议分配会议标识，以使得终端通过应用客户端输入该会议标识接入该会议。应理解，会议标识可以用红外设备110(例如数据处理模块113)生成，也可以由云服务器120在接收到会议内容中的坐标信息后对应生成，本发明实施例对此不作限定。终端通过输入会议标识(会议ID)或会议ID和对应的会议接入密码与会议ID绑定，以实现云服务器120向加入会议的终端发送会议内容。此外，本发明实施例中，终端也可以通过扫描红外设备110的唯一的物理ID，将终端与红外设备110绑定，从而进一步实现与会议绑定的目的。
通过上述行为，使用终端的用户要获取会议内容，需要通过安全认证过程，即仅允许安全用户访问云服务器120存储的书写内容。终端可以直接进行安全设置，也可以结合其它工具进行安全设置，例如微信、摇一摇等，从而提高安全性。云服务器120可以向终端提供丰富的分享模式，例如实时会议、会议文件、邮件等等，本发明实施例对此不作限定。
应理解，终端扫描红外设备110可以通过二维码、条形码或蓝牙等，本发明实施例对此不作限定。还应理解，本发明实施例中的终端与会议绑定，终端与红外设备110绑定，可以是以ID的形式对应，例如形成表来形成对应关系，但本发明实施例并不仅限于此。
应理解，数据处理模块113可以将坐标信息和坐标信息对应的时间信息以系统指定的数据格式融合，形成综合数据。坐标信息对应的时间信息可以 通过计时器生成，也可以通过其它的计时设备生成，本发明实施例对此不作限定。
相应地，可选地，在本发明实施例中，该综合数据包括该红外线位置检测模块111按时间顺序获取的坐标信息，以便于该终端根据该按时间顺序获取的坐标信息再现书写的过程。可选地，在本发明实施例中，该综合数据包括该坐标信息和与该坐标信息对应的时间信息，以便于该终端根据该时间信息和该坐标信息再现书写的过程。终端接收并云服务器120发送的坐标信息和时间信息，根据该坐标信息和时间信息，对会议中的书写内容执行快进操作、后退操作或从特定时刻再现。
换而言之，时间信息可以以隐式的方式指示，也可以以显示的方式指示。对于隐式指示，例如以5ms为间隔，坐标信息占据n个比特，则第一个n比特表示第一个5ms的坐标信息，第二个n比特标识第二个5ms的坐标信息，……依此类推。这种方式要求在用户没有书写任何内容的空窗期时，以特定值填充坐标信息。
对于显式指示，数据处理模块113可以在综合数据中，增加与坐标信息对应的时间信息。例如，可以使用具体时刻值，也可以使用序号(每两个序号之间的间隔是预定义好的)外加初始时刻值的方式，但本发明实施例并不仅限于此。本发明实施例中加入时间信息，可以使整个书写过程更完整地再现，给用户更好的体验，而不是传统的那样仅仅再现书写的最终结果。
可选地，在本发明实施例中，该红外设备110还用于外接音频设备，以便于通过该音频设备输入或输出音频数据。或者，可选地，该红外设备110还包括音频模块，以便于通过该音频模块输入或输出音频数据。
具体而言，如图3所示，上述音频设备或音频模块可以包括麦克风160和/或扬声器170。麦克风160可以实现会议中将进行书写的用户的语音输入。扬声器170可以帮助终端的客户端对书写的用户的语音实现反馈。应理解，该反馈可以是实时反馈，也可以是延后反馈，延后反馈时其功能类似于留言机功能。此外，扬声器170还可以用于为会议播放背景音乐。该音频设备或音频模块使得再现的会议内容更丰富，扬声器则更是可以实现会议反馈能力，可以增强用户的体验。
应理解，本发明实施例的音频设备或音频模块，例如麦克风160和/或扬声器170还可以内置在红外设备110中，也可以通过线路、WLAN、蓝牙技 术或红外技术与该红外设备110连接。麦克风160采集的数据可以融合入综合数据，发送给云服务器120，并传输至参与会议的终端。
可选地，在本发明实施例中，该红外设备110还用于外接本地再现设备，该数据处理模块113还用于将该综合数据发送给该本地再现设备，以便于该本地再现设备根据该综合数据在本地进行再现该会议的内容。
具体而言，如图3所示，红外设备110还可以外接本地再现设备，例如图3中的显示器180和打印机190等。红外设备110通过数据处理模块113将会议产生的综合数据发送给该本地再现设备。该本地再现设备根据该综合数据在本地再现该会议的内容，可以进一步增强用户的体验。例如，通过显示器180在本地显示会议的内容，或由相应的程序控制打印机，通过打印机将会议内容打印出来等。此外，本地再现设备还可以对再现的内容进行渲染，如场景模拟、现实增强等，以增强会议效果。可选地，该本地再现设备可以为显示设备或打印设备，但本发明实施例并不仅限于此。应理解，该本地再现设备可以通过线路、WLAN、蓝牙技术或红外技术与该红外设备110连接。
可选地，在本发明实施例中，除将本地再现设备与红外设备110连接，接收红外设备110数据的方案以外，本地再现设备的数据也可以来自于云服务器120。相应地，该云服务器120还用于与本地再现设备通信连接，该云服务器120将该综合数据发送给该本地再现设备，以便于该本地再现设备根据该综合数据在本地再现该会议的内容。
在具体的实现中，用户可以通过红外设备110上的按钮等硬件或者通过微信、APP等软件发出本地再现指示。如果本地再现指示是通过红外设备110上的按钮等硬件发出的，则由红外设备110向该云服务器120发送指示信息，指示云服务器120将该综合数据发送给该本地再现设备；如果本地再现指示是通过软件发出的，则该指示可以发送给红外设备110，由红外设备110向该云服务器120发送指示信息，也可以是直接发送给云服务器的。应理解，在本发明实施例中，本地再现设备的数据也可以来自于云服务器120，需要将本地再现设备在云服务器120处或红外设备110处进行注册或绑定，其注册或绑定的方式与红外设备110、云服务器120、用户使用的终端的绑定可以相类似，本文中不再进行赘述。
因此，本发明实施例提供的多用户会议系统，通过用户在会议中书写时，书写物体对红外设备的红外线分布情况的影响，确定书写物体的坐标信息， 将坐标信息处理后的综合数据发送至云服务器，以便于参与会议的终端根据综合数据再现会议中的书写内容，可以基于非图像数据传输会议内容，能够实现会议内容的远程推送，并可以节省流量，降低会议系统对网络流量的要求。另外，相比于现有的拍摄或视频模式，本发明实施例的方案更节省流量，并且再现效率高，即在相同数据流量的情况下，本实施例的方案的采样频率高得多。
本领域普通技术人员可以意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以电子硬件、或者计算机软件和电子硬件的结合来实现。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
