下面结合附图和实施例对本发明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仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部内容。
实施例一
图2为本发明实施例一提供的一种交互设备的结构示意图。参考图2，本发明实施例提供的交互设备，包括红外智能笔1和红外触控显示器2，红外智能笔1包括智能笔微处理器11和第一红外发射器12，第一红外发射器12与智能笔微处理器11相连。
智能笔微处理器11，用于将所述红外智能笔1的特征码编码后传输到所述第一红外发射器12。
第一红外发射器12，用于发射携带有所述特征码的红外信号。
红外触控显示器2包括红外触摸框21和触控微处理器22，红外触摸框21与触控微处理器22相连。
红外触摸框21，用于进行触控位置的检测，并接收第一红外发射器12发射的红外信号。
触控微处理器22，用于解码所述红外信号获得所述特征码，并根据所述特 征码和所述触控位置生成触控轨迹，不同特征码对应的触控轨迹具有不同的显示属性不同。
在本实施例中，智能笔微处理器11和第一红外发射器12位于红外智能笔1的内部。第一红外发射器12可以为红外发射灯。红外触摸框21设置于红外触控显示器2的显示面，触控微处理器22位于红外触控显示器2内部。
可选的，红外智能笔1中还可以包括与智能笔微处理器11相连的红外接收器(图未示)，用于接收外部的红外信号，并将红外信号发送至智能笔微处理器11进行后续处理。其中，红外接收器可以是红外接收灯或红外光敏元件。
在上述实施例的基础上，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，参考图3，红外触摸框21包括第一红外接收器211、第二红外发射器212和第二红外接收器213，第一红外接收器211、第二红外发射器212和第二红外接收器213均与触控微处理器(图3未示)相连。
第一红外接收器211用于接收第一红外发射器12发射的红外信号，第二红外发射器212和第二红外接收器213用于进行所述触控位置的检测。
可选的，第二红外发射器212和第二红外接收器213分别设置两列，第二红外发射器212与第二红外接收器213在红外触摸框21的内侧壁相对设置，这样可以使得第二红外发射器212尽量向更大的范围发射红外信号，第二红外接收器213尽量接收到更大范围的红外信号。
其中，第二红外接收器213可以接收到第二红外发射器212发送的红外信号，当红外智能笔1在第二红外发射器212发射范围内进行触控操作时，第二红外接收器213接收不到对应的第二红外发射器212发射的红外信号，纵横两个方向上的红外信号的接收情况的综合从而确认触控发生的纵横方向上的坐标，即可以确定红外智能笔1的触控位置。第二红外接收器213还可以接收外 部的红外信号。
进一步的，第一红外接收器211的具体个数，本实施例不作限定。同时，还可以根据实际情况设置第一红外接收器211的安装位置，图3中第一红外接收器211的安装位置仅是一种示例性的说明。
其中，第一红外接收器211和第二红外接收器213可以为红外接收灯管，第二红外发射器212可以为红外发射灯管。
可选的，红外触控显示器2还包括整机主控芯片(图未示)，整机主控芯片通过USB和UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)接口连接上述触控微处理器22，用于接收触控微处理器22解码红外信号时获取的控制指令(如翻页指令)，并根据该控制指令执行相应的操作。
可选的，红外触摸框21与显示面的朝向相同的一侧还可以设置第三红外接收器(图未示)。其中，第三红外接收器可以为红外接收头。第三红外接收器可以接收红外信号，并将该红外信号转发给整机主控芯片(图未示)。该第三红外接收器设置于红外触摸框21边角的外表面，并垂直上述显示面。第三红外接收器可以接收红外触控显示器2正前方15米及左右15°范围内的红外信号，当第一红外接收器211和第二红外接收器213无法接收到红外智能笔1发送的红外信号时，可以通过第三红外接收器接收红外智能笔1发送的红外信号。
本实施例一提供的交互设备，智能笔微处理器将编码后的红外智能笔的特征码发送至第一红外发射器，以使第一红外发射器发射携带有该特征码的红外信号。红外触摸框获取触控位置以及红外信号，通过触控微处理器获取红外信号中特征码，以根据特征码和触控位置生成触控轨迹在显示屏中显示，且不同特征码对应的触控轨迹的显示属性不同，可以实现在红外触控显示屏中实现多个红外智能笔同时书写。另外，以红外线方式进行通信，也可以节约设备生产 成本，并减少外界信号的干扰。
实施例二
图4为本发明实施例二通过的一种轨迹生成方法的流程图。本实施例提供的轨迹生成方法可以由轨迹生成装置执行，该轨迹生成装置可以通过软件和/或硬件的方式实现，并集成在红外触控显示器的触控微处理器中。参考图4，本实施例提供的轨迹生成方法具体包括：
S410、接收通过红外触摸框检测红外智能笔的触控过程中得到的触控位置和红外信号。
在本实施例中，红外智能笔与红外触控显示器进行交互，其中，红外智能笔在红外触控显示器的红外触摸框检测范围内执行触控操作，同时通过第一红外发射器向外发射红外信号。
具体的，红外智能笔在触控过程中，红外触摸框可以实时获取对应的触控位置，还可以实时接收红外信号。
进一步的，红外触摸框将检测的触控位置和接收的红外信号发送至触控微处理器。
S420、解码所述红外信号获取所述红外智能笔的特征码。
考虑到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，因此，需要触控微处理器解码接收的红外信号，以确定该红外信号所属的红外智能笔。
具体的，红外智能笔在发射红外信号时，会在红外信号中携带红外智能笔的特征码。其中，不同的红外智能笔对应的特征码不同。本实施例中，红外智能笔通过智能笔微处理器进行特征码的编码，通过第一红外发射器向外发射携 带特征码的红外信号，具体可参考实施例一提供的交互设备中提供的红外智能笔和红外触控显示器。本实施例中不限定红外智能笔中智能笔微处理器对特征码的编码规则。
进一步的，红外触控显示器中预先存储交互的红外智能笔的特征码，在解码红外信号获取特征码后，将该特征码与预先存储的特征码进行匹配，便可以确定与当前红外信号对应的红外智能笔。
S430、根据所述特征码和触控位置生成触控轨迹，不同特征码对应的触控轨迹具有不同的显示属性。
示例性的，触控微处理器中还预先存储不同的特征码对应的触控轨迹的显示属性。其中，显示属性可以包括颜色、粗细和虚实中的至少一种。即根据显示属性可以确定触控轨迹在显示面中显示的样式。
具体的，触控微处理器根据解码红外信号得到的特征码确定对应的触控轨迹的显示属性，同时，根据触控位置生成触控轨迹，并在显示屏中根据显示属性显示该触控轨迹。
本实施例的技术方案，触控微处理器接收红外触摸框检测得到的触控位置和红外信号，通过解码红外信号确定红外智能笔的特征码，并根据该特征码确定对应的触控轨迹的显示属性，在根据触控位置得到触控轨迹时，根据显示属性在显示屏中显示该触控轨迹。实现了红外智能笔在红外触控显示器中的书写操作，同时，通过红外通信方式减少了设备的生产成本。通过特征码对红外信号的来源进行确定，消除了其他信号对红外触控显示器的干扰，并实现了区分不同红外智能笔书写时的触控轨迹，提升了用户的使用体验。
实施例三
图5为本发明实施例三提供的一种轨迹生成方法的流程图。本实施例是在上述实施例的基础上进行优化。在本实施例中，红外智能笔的个数为至少两个，参考图5，本实施例提供的轨迹生成方法具体包括：
S510、接收通过红外触摸框检测红外智能笔的触控过程中得到的触控位置和红外信号。
当多个红外智能笔同时执行触控操作时，由于发射的红外信号具有方向性，所以红外触摸框横向上的第一红外接收器或第二红外接收器接收到的红外信号也具有方向性。
具体的，各红外智能笔在显示面中执行触控操作时水平位置不同，使得红外触摸框横向上的第一红外接收器或第二红外接收器接收不同红外信号时接收位置不同。
S520、解码所述红外信号获取所述红外智能笔的特征码。
S530、根据所述红外触摸框横向上的第一红外接收器或第二红外接收器接收到的红外信号确认所述触控位置对应的特征码。
由于触控微处理器获取的触控位置中不包含红外智能笔的特征码，因此需要判断触控位置对应的特征码，以确定不同红外智能笔对应的触控位置。
具体的，触控微处理器可以确定检测的触控位置与红外触摸框的相对位置。
示例性的，在触控微处理器接收到多个红外信号时，根据红外触摸框横向上的第一红外接收器或第二红外接收器接收红外信号的接收位置确认红外智能笔在显示面中执行触控操作的大概区域，并将与该区域最匹配的触控位置作为该红外信号对应的触控位置，进而确定不同触控位置对应的特征码。
S540、根据所述触控位置生成触控轨迹，并将所述触控轨迹显示为对应的特征码设定的显示属性。
具体的，确定不同特征码对应的触控轨迹的显示属性，并根据显示属性显示不同特征码对应的触控位置生成的触控轨迹。
例如，图6为本发明实施例三提供的红外触摸框检测多个红外智能笔触控操作的示意图。参考图6，红外触摸框21检测到三个红外智能笔的触控操作，且三个红外智能笔分别在显示面的区域61、区域62和区域63执行触控操作。红外触摸框21横向上第一红外接收器211接收到三个红外信号的位置分别为位置64、位置65和位置66，则可以确定位置64接收的红外信号对应于红外触摸框21在区域61检测到的触控位置，位置65接收的红外信号对应于红外触摸框21在区域62检测到的触控位置，位置66接收的红外信号对应于红外触摸框21在区域63检测到的触控位置，进一步的，确定各触控位置对应的特征码和触控轨迹，并将触控轨迹显示为对应的特征码设定的显示属性。
本实施例的技术方案，触控微处理器接收红外触摸框检测的触控位置和多个红外信号，并解码多个红外信号的特征码，通过红外触摸框横向上的第一红外接收器或者第二红外接收器接收的红外信号确定不同触控位置对应的特征码，进而根据不同特征码对应的触控轨迹的显示规则显示不同触控位置对应的触控轨迹。实现了通过红外通信方式在红外触控显示器中显示多个红外智能笔的触控轨迹，消除了其他红外信号的干扰，提升了用户的使用体验。
实施例四
图7为本发明实施例四提供的一种轨迹生成方法的流程图。本实施例是在上述实施例的基础上进行优化。在本实施例中，红外智能笔的个数为至少两个，参考图7，本实施例提供的轨迹生成方法具体包括：
S710、接收通过红外触摸框检测红外智能笔的触控过程中得到的触控位置 和红外信号。
具体的，红外智能笔发送的红外信号中，不仅包括红外智能笔的特征码，还包括信号ID，其中，信号ID中填入红外智能笔在本次交互过程中发出的红外信号的个数。
典型的，红外触摸框可以根据同一时刻检测到的触控位置的个数确定当前执行触控操作的红外智能笔的个数，且各红外智能笔在显示面中执行触控操作时水平位置不同。此时，红外触摸框纵向上的第一红外接收器或第二红外接收器可以接收到多个红外智能笔的发送的红外信号。
S720、解码所述红外信号获取所述红外智能笔的特征码。
S730、根据所述红外触摸框纵向上的第一红外接收器或第二红外接收器接收到的红外信号的丢包率确认所述触控位置对应的特征码。
具体的，触控微处理器在解码红外触摸框纵向上的第一红外接收器或第二红外接收器接收到的红外信号时，记录同一特征码的信号ID，并根据信号ID确定同一红外智能笔发射红外信号的丢包率。
典型的，红外触摸框纵向上的第一红外接收器或第二红外接收器接收红外信号时，不同红外智能笔与红外触摸框纵向上的第一红外接收器或第二红外接收器的距离不同，使得不同红外智能笔发射红外信号的丢包率不同。其中，丢包率越低，表明接收该红外智能笔与红外触摸框纵向上的第一红外接收器或第二红外接收器距离越近，使得接收的红外信号越准确。
因此，可以根据接收的红外信号的丢包率确认不同红外智能笔的触控位置，即触控位置对应的特征码。
S740、根据所述触控位置生成触控轨迹，并将所述触控轨迹显示为对应的特征码设定的显示属性。
例如，图8为本发明实施例四提供的红外触摸框检测多个红外智能笔触控操作的示意图。参考图8，红外触摸框21检测到两个红外智能笔的触控操作，且两个红外智能笔分别在显示面的区域81和区域82执行触控操作。红外触摸框21纵向上的第二红外接收器213接收两个红外智能笔发射的红外信号，通过触控微处理器确定一个特征码对应的红外信号的丢包率为10％，另一个特征码对应的红外信号的丢包率为8％，则可以确定丢包率为8％的特征码对应于红外触摸框21在区域81检测到的触控位置，丢包率为10％的特征码对应于红外触摸框21在区域82检测到的触控位置，根据触控位置确定触控轨迹，并将触控轨迹显示为对应的特征码设定的显示属性。
本实施例的技术方案，触控微处理器接收红外触摸框检测的触控位置和多个红外信号，并解码多个红外信号的特征码，通过红外触摸框纵向上的第一红外接收器或者第二红外接收器接收的红外信号的丢包率确定不同触控位置对应的特征码，进而根据不同特征码对应的触控轨迹的显示规则显示不同触控位置对应的触控轨迹。实现了通过红外通信方式在红外触控显示器中显示多个红外智能笔的触控轨迹，消除了其他红外信号的干扰，提升了用户的使用体验。
