Description

一种智能书写方法、红外触摸屏与智能书写系统 技术领域
本发明涉及触摸技术领域，尤其涉及一种智能书写方法、红外触摸屏与智能书写系统。
背景技术
随着触摸技术的发展，现在出现了与红外触摸屏(例如用于自动发布多媒体信息的数字标牌或者用于课堂上与学生进行互动的教育设备等)配合使用的触摸输入装置(例如触摸笔)。
现有的红外触摸屏能获取触摸物体在红外触摸屏上的触摸轨迹，但却没有办法识别不同的触摸物体的触摸轨迹并区分显示。
例如，不同的学生在红外触摸屏上作答以及老师在红外触摸屏上写正确的答案。为了明确区分不同的人的书写内容，理想的方案是为每个用户分别配置“一支不同颜色的笔”使得每个人的书写内容的颜色不一样。但实际上，现有的红外触摸屏没有办法识别不同的触摸轨迹，对于不同触摸物体写出来的内容，其显示状态是一样的，这样没办法实现差异化书写。此外，现有的红外触摸屏也没有办法识别用户是用手进行书写还是用书写笔进行书写。

附图说明
为了更清楚地说明本发明的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的一种智能书写方法的流程示意图；
图2是本发明实施例提供的一种红外触摸屏10的结构框图；
图3是本发明实施例提供的智能书写系统的结构示意图；
图4是图3中的智能书写笔20的局部结构放大图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，其是本发明实施例提供的一种智能书写方法的流程示意图。
所述智能书写方法包括：
S11，红外触摸屏检测触摸物体在所述红外触摸屏上产生的触摸轨迹；
S12，红外触摸屏接收所述触摸物体发出的第一红外发射信号所对应的第一红外接收信号；
S13，红外触摸屏根据所述第一红外接收信号的波长识别所述触摸物体；
S14，红外触摸屏根据预先配置的不同触摸物体与笔迹显示状态的对应关系，确定识别到的触摸物体的待配置笔迹显示状态；
S15，红外触摸屏显示与所述触摸轨迹对应的、具有所述待配置笔迹显示状态的笔迹。
在本发明实施例中，红外触摸屏通过获取触摸物体发出的第一红外发射信号所对应的第一红外接收信号，并根据第一红外接收信号的波长来识别触摸物体，使得不同触摸物体的笔迹通过不同的笔迹显示状态来显示，实现了差异化书写。其中，触摸物体可以是一般书写物或者智能书写笔。一般书写物指的是不能发射出第一红外发射信号的物体，例如手指或者普通的笔。而智能书写笔则是指能够发射出第一红外发射信号的物体，并且为了区分不同的智能书写笔，不同的智能书写笔所发射出的第一红外发射信号的波长可以配置成不同的。
在本实施例中，所述笔迹显示状态为笔迹颜色、笔迹宽度、笔迹形状中的任一种及其组合。例如，480nm波长所对应的触摸物体的笔迹颜色配置为红色，560nm波长所对应的触摸物体的笔迹颜色配置为绿色，而没有发射第一红外发射信号的触摸物体的笔迹颜色配置为黑色。以上任意一个能够区分不同触摸物体的笔迹的方案都属于本发明的保护范围内。
其中，在步骤S11中，所述红外触摸屏检测触摸物体在所述红外触摸屏上产生的触摸轨迹包括：
所述红外触摸屏通过设置在所述红外触摸屏上的触摸屏发射灯发射第二红外发射信号；
所述红外触摸屏通过设置在所述红外触摸屏上的触摸屏接收灯接收所述第二红外发射信号所对应的第二红外接收信号；
所述红外触摸屏根据所述第二红外发射信号以及所述第二红外接收信号获取所述触摸物体在所述红外触摸屏上产生的触摸轨迹。
其中，所述红外触摸屏根据所述第二红外发射信号以及所述第二红外接收信号获取所述触摸物体在所述红外触摸屏上产生的触摸轨迹的具体工作过程为：所述触摸屏发射灯分别设置在所述触摸屏的触摸框的相邻的两条侧框上，所述触摸屏接收灯分别设置在所述触摸屏的触摸框的另外两条侧框上，并组成一个发射和接收阵列；所述红外触摸屏控制触摸屏发射灯发出第二红外发射信 号，并通过触摸屏接收灯接收相应的第二红外接收信号；当所述触摸物体与所述红外触摸屏接触时，触摸物体会遮挡住部分的光路，所述红外触摸屏因此能够根据第二红外发射信号与第二红外接收信号确定遮挡住光路的区域即触摸物体在红外触摸屏的坐标位置。当所述触摸物体在所述红外触摸屏上书写移动时，根据获取到的所述触摸物体的各个时刻点的所述坐标位置就可以获取所述触摸物体的触摸轨迹。
优选地，所述红外触摸屏接收所述触摸物体所发出的第一红外发射信号所对应的第一红外接收信号，具体为：所述红外触摸屏通过所述触摸屏接收灯接收所述触摸物体所发出的第一红外发射信号所对应的第一红外接收信号。即在本发明实施例中，所述触摸屏接收灯同时用于接收所述第一红外接收信号与所述第二红外接收信号，而不用另外设置接收灯用于接收所述第一红外接收信号，节约了成本。
由于在本实施例中，所述触摸屏接收灯同时用于接收所述第一红外接收信号与所述第二红外接收信号，为了区分两种红外发射信号，所述第二红外发射信号的波长与任一触摸物体所发出的第一红外发射信号的波长都不同。
为了实施上述的智能书写方法，本发明实施例还提供了一种红外触摸屏。请参阅图2，其是本发明实施例提供的一种红外触摸屏的结构框图。
