实施例一

其中，输入单元13，用于接收用户执行的翻页操作并发送至智能笔微处理器12。
智能笔微处理器12，用于根据所述翻页操作编码相应的翻页指令，并将编 码后的翻页指令传输给第一红外发射器14。
第一红外发射器14，用于发射携带有编码后的翻页指令的红外信号。
显示设备2包括：整机主控芯片21和红外触摸框23，红外触摸框23设置有第二红外接收器24和触摸框微处理器22，触摸框微处理器22分别与第二红外接收器24和整机主控芯片21相连。
第二红外接收器24，用于接收携带有编码后的翻页指令的红外信号。
触摸框微处理器22，用于解码第二红外接收器24接收的红外信号，以获取翻页指令，并将所述翻页指令发送至整机主控芯片21。
整机主控芯片21，用于根据接收的翻页指令执行相应的操作。
在本实施例中，第一红外发射器14可以为红外发射灯。第二红外接收器24可以为红外接收灯管。
可选的，输入单元13可以是按键、触摸屏或者小型摇杆。图2以按键为例，输入单元13包括上按键131和下按键132，当接收用户点击上按键131时，表明用户执行翻至前一显示页面的操作，当接收用户点击下按键132时，表明用户执行翻至后一显示页面的操作。需要说明的是，输入单元13还可以设置为其他方式，本实施例不作限定。
进一步的，在显示设备2显示面的四周设置有红外触摸框23。红外触摸框23上设置有第二红外接收器24和触摸框微处理器22。一般而言，触摸框微处理器22也可以根据实际情况设置在红外触摸框23以外的显示设备2的内部。
具体的，整机主控芯片21位于显示设备2的内部，整机主控芯片21通过USB和UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)接口(图未示)连接触摸框微处理器22，以接收触摸框微处理器22发送的翻页指令，并根据该翻页指令执行相应的翻页操作。
在上述实施例的基础上，显示设备2的红外触摸框23还设置有第二红外发射器25，第二红外发射器25与触摸框微处理器22相连；第二红外发射器25，用于作为信号源向外发射红外信号；触摸框微处理器22，还用于编码需要向外发送的信息并传输给所述第二红外发射器25。相应的，智能笔1还包括设置于智能笔本体内部的第一红外接收器15，第一红外接收器15与智能笔微处理器12相连；第一红外接收器15，用于接收外部的信号源发射的红外信号；智能笔微处理器12，还用于解码第一红外接收器15接收的红外信号。
其中，第一红外接收器15可以为红外接收灯或红外光敏元件，第二红外发射器25可以为红外发射灯管。
具体的，第一红外接收器15的光敏元件(图未示)的朝向与第一红外发射器14的发射元件(图未示)的朝向相同。其中，该光敏元件和发射元件均朝向与智能笔1配合使用的显示设备2，以使智能笔1内部的第一红外接收器15及第一红外发射器14，与该显示设备2以较佳的角度进行信号交互。
可选的，图3为本发明实施例一提供的一种红外触摸框的结构示意图，该红外触摸框23中未示出触摸框微处理器22。如图3所示，第二红外发射器25与第二红外接收器24分别设置两列，第二红外发射器25与第二红外接收器24在红外触摸框23的内侧壁相对设置。其中，第二红外发射器25与第二红外接收器24在红外触摸框23的内侧壁相对设置，这样使得第二红外发射器25可以尽量向更大的范围发射红外信号，也使得第二红外接收器24可以尽量接收到更大范围内的红外信号。
在上述实施例的基础上，红外触摸框23与显示面的朝向相同的一侧还设置有第三红外接收器26。
其中，第三红外接收器26可以为红外接收头。
进一步的，第三红外接收器26用于接收智能笔1的第一红外发射器14发射的红外信号，并将该红外信号转发给整机主控芯片21。该第三红外接收器26设置于红外触摸框23边角的外表面(图2仅示例性的设置在右下角)，并垂直上述显示面，第三红外接收器26的光敏元件(图未示)的朝向垂直上述显示面。当智能笔1离红外触摸框23的距离过远时，红外触摸框23的第二红外接收器24难以接收到智能笔1发出的红外信号，智能笔1的第一红外发射器14发射的红外信号可以通过第三红外接收器26中转后发送给上述整机主控芯片21，第三红外接收器26可以接收整机正前方15米及左右15°范围内的红外信号。
本发明实施例一提供的交互设备，通过在智能笔本体的表面设置输入单元，在智能笔本体的内部设置第一红外发射器，且输入单元和第一红外发射器分别与智能笔微处理器连接，在显示设备处设置包含触摸框微处理器和第二红外接收器的红外触摸框，且触摸框微处理器分别与整机主控芯片和第二红外接收器相连。输入单元将接收到的用户翻页操作发送给智能笔微处理器，智能笔微处理器编码翻页操作对应的翻页指令并发送给第一红外发射器，以使第一红外发射器发送包括翻页指令的红外信号，触摸框微处理器解码第二红外接收器接收的红外信号，得到翻页指令，并将翻页指令发送至整机主控芯片，使整机主控芯片根据翻页指令执行翻页操作，实现了智能笔与相互配合使用的显示设备之间采用红外信号方式进行通信，简化了智能笔操作，降低了产品的生产成本，同时，减少了外界信号的干扰。
实施例二
图4为本发明实施例二提供的一种交互方法的流程图。本实施例提供的交互方法可以由交互系统来执行，该交互系统可以通过软件和/或硬件的方式实现。
参考图4，本实施例提供的交互方法具体包括：
S410、智能笔接收用户执行的翻页操作，并根据所述翻页操作编码相应的翻页指令。
本实施例提供的方法适用于包括智能笔和显示设备的交互设备，如上述实施例提供的交互设备。
示例性的，当前智能笔处于工作激活状态，其中，工作激活状态是指智能笔与显示设备完成同步后，可以进行通信的状态。
具体的，智能笔接收用户执行的翻页操作，根据翻页操作生成对应的翻页指令，其中，翻页指令包括：翻至前一显示页面指令和翻至后一显示页面指令。用户可以通过按压智能笔的输入单元，输入翻页操作。
进一步的，智能笔生成翻页指令后，对该翻页指令进行编码。其中，具体的编码规则本实施例不作限定。
S420、所述智能笔发射携带有编码后的翻页指令的红外信号。
示例性的，智能笔将编码后的翻页指令可以映射到待发射的红外信号中，并发射携带有编码后的翻页指令的红外信号。其中，智能笔可以通过自身的第一红外发射器向外发射翻页指令。
其中，红外信号还可以包含其他的数据，数据的具体内容本实施例不作限定。
S430、红外触摸框解码接收的红外信号，以获取翻页指令。
示例性的，红外触摸框接收红外信号后解码该红外信号，以获取红外信号中携带的翻页指令。其中，具体的解码规则根据上述编码规则确定。
考虑到显示设备中红外触摸框可以接收到接收范围内全部的红外信号，且无法判断接收红外信号的来源，此时，需要解码接收的红外信号，以确定是否 为当前交互的智能笔发出的红外信号，并在确定为当前交互的智能笔发出的红外信号后，获取红外信号中包含的翻页指令。
具体的判断方法可以是：智能笔编码智能笔的特征码，并发射包含编码后的翻页指令和特征码的红外信号。红外触摸框解码接收的红外信号时，先确认是否可以在红外信号中获取到特征码，并在获取到特征码时，判断该特征码是否为交互的智能笔的特征码，若是，则确认红外信号为当前交互的智能笔发出的红外信号。
其中，每个智能笔都有对应的特征码，不同智能笔对应的特征码不同。如果智能笔与显示设备是成套设备，那么智能笔与显示设备应预先相互保存对方的特征码，例如产品序列号、机器码等。可选的，也可以由用户将智能笔的特征码录入显示设备中，以使显示设备确定当前交互的智能笔的特征码。
进一步的，红外触摸框可以将解码得到的特征码与预存的特征码进行匹配，以确认当前接收的红外信号是否为交互的智能笔发出的红外信号，这样可以消除其他红外信号对显示设备造成的干扰。
S440、所述红外触摸框将所述翻页指令发送给整机主控芯片，以使所述整机主控芯片执行所述翻页指令。
具体的，红外触摸框将翻页指令发送给整机主控芯片，整机主控芯片执行翻页指令，即控制显示内容进行翻页。
本实施例的技术方案，智能笔通过编码与用户执行的翻页操作对应的翻页指令，并将翻页指令以红外信号的方式进行发射，红外触摸框解码接收的红外信号，以获取翻页指令，并将翻页指令发送至整机主控芯片，以使整机主控芯片执行翻页操作的技术手段，简化了智能笔的操作，实现了智能笔与显示设备间通过红外通信方式传输翻页指令，降低了智能笔和显示设备的生产成本，同 时，降低了外界信号对显示设备的干扰。
实施例三
图5为本发明实施例三提供的一种交互方法的流程图。本实施例以上述实施例的基础上为优化，参考图5，本实施例提供的交互方法具体包括：
S510、红外触摸框将智能笔识别区域信息编码并向外发射。
其中，智能笔识别区域是指红外触摸框能识别智能笔的有效识别区域，该区域是在一定范围内的一个空间区域，在本实施例中该区域的范围大小可调。
示例性的，红外触摸框相对于智能笔就是一个外部信号源，红外触摸框发出的红外信号中可以携带有完整的智能笔识别区域信息，还可以携带有完整的红外触摸框的特征码。红外触摸框将智能笔识别区域信息及红外触摸框的特征码进行编码，并将编码后得到的信息以红外信号的方式向外发射。
具体的，交互的智能笔与显示设备中应预先相互保存对方的特征码。
若交互的智能笔和显示设备中没有预先保存对方的特征码，则可以由用户在显示设备中添加智能笔的特征码。此时，显示设备第一次向智能笔发送的红外信号中不仅包括编码后的智能笔识别区域信息和红外触摸框的特征码，还包括编码后的智能笔的特征码。其中，可以由红外触摸框对智能笔的特征码进行编码。
相应的，智能笔解码该红外信号时，若确定该红外信号中包含自身的特征码，则可以确认该红外信号为发给自己的红外信号，即进行一个简单的握手。此时，智能笔进行初始化，并保存红外触摸框的特征码。
可选的，显示设备向非首次同步的智能笔发射红外信号时，红外触摸框仅需对智能笔识别区域信息及红外触摸框的特征码进行编码即可。
S520、智能笔解码接收的外部信号源发射的红外信号。
示例性的，智能笔可以随时接收外部存在的红外信号，并对该红外信号进行解码处理。其中，外部信号源可以为红外触摸框，或为其他可发出红外信号的设备。
考虑到智能笔接收红外信号时，无法确认该红外信号的来源，因此，需要对红外信号进行解码后才能明确该红外信号的来源，并根据解码结果进行后续操作。
S530、智能笔判断通过解码所述外部信号源发射的红外信号得到的信息中是否携带有完整的智能笔识别区域信息。若携带有完整的智能笔识别区域信息，则执行S540，否则，执行S550。
具体的，智能笔中预先还存有交互显示设备的智能笔识别区域信息。智能笔将解码得到的智能笔识别区域信息和红外触摸框的特征码与预先存储的交互显示设备的智能笔识别区域信息和红外触摸框的特征码进行比对，以确认解码的智能笔识别区域信息和红外触摸框的特征码是否完整。若完整，则说明智能笔进入到该智能笔识别区域，执行S540。否则，执行S550。
需要说明的是，与步骤S510对应的，如果是初次接收到红外信号，该红外信号携带的完整的信息还应该包括智能笔自身的特征码。
S540、智能笔自动激活。执行S560。
例如，设置垂直距红外触摸框20厘米范围内为智能笔识别区域，当智能笔进入到该智能笔识别区域时，激活智能笔，整机系统自动打开电子白板应用，或其它自定义功能，例如PPT(Power Point，演示文稿)批注等。
本方案中的智能笔不是随意激活并发射红外信号，而是需要对红外信号的身份进行认证，基于身份认证的激活确认能够消除信号接收时的干扰，只有认 证后的智能笔才能被响应。
S550、智能笔继续保持未激活的状态。返回执行S520。
S560、智能笔接收用户执行的翻页操作。
S570、智能笔根据所述翻页操作编码相应的翻页指令，得到所述翻页指令的码值信息。
具体的，对翻页指令进行编码得到相应的码值信息。
S580、智能笔编码智能笔的特征码。
S590、智能笔发射携带有翻页指令的码值信息和智能笔的特征码的红外信号。
其中，所述红外信号中包括所述智能笔的特征码和翻页指令的码值信息。
S5100、红外触摸框解码接收的红外信号，以获取所述红外信号中携带的智能笔的特征码和翻页指令的码值信息。
S5110、红外触摸框判断获取到的特征码是否与当前交互智能笔的特征码匹配。若匹配，则执行S5120，否则，执行S5130。
具体的，若红外触摸框获取到的特征码与当前交互智能笔的特征码相同，则确认该红外信号为当前交互智能笔发射的信号，执行S5120。否则，执行S5130。
S5120、红外触摸框发送所述码值信息给整机主控芯片，以使所述整机主控芯片执行所述翻页指令。
S5130、红外触摸框停止对当前红外信号的处理。
本实施例提供的技术方案，智能笔通过确认智能笔识别区域信息和红外触摸框特征码以对智能笔进行激活，显示设备通过确认智能笔特征码以执行翻页指令，可以消除外界信号的干扰，此外，通过红外通信方式，智能笔进入到红外触摸框的智能笔识别区域时即可激活智能笔，实现红外触摸框对智能笔的悬 浮识别，极大地提升了用户体验。
