Description

触摸图形宽度的检测、触摸图形识别方法和系统 技术领域
本发明涉及触摸信息处理技术领域，特别是涉及一种触摸图形宽度的检测、触摸图形识别方法和系统。
背景技术
近年来，触摸设备已广泛应用到了人们的工作和生活中，这便对触摸设备上相关触摸信息的处理提出了更高的要求。
通常情况下，为了将触摸点的宽度或者面积等信息传递给PC端的应用软件，触摸设备的触摸框等触摸输入设备本应该将触摸宽度信息和触摸坐标信息统一交由相应的操作系统来分发给应用软件。但是由于将宽度信息传递给操作系统的技术较为复杂，导致部分厂商的触摸输入设备仅能向操作系统报告坐标信息，而不会将宽度信息一并报告给上述操作系统，从而影响应用软件获取触摸信息的效果。
发明内容
基于此，有必要针对传统技术影响应用软件获取触摸信息效果的技术问题，提供一种触摸图形宽度的检测、触摸图形识别方法和系统。
一种触摸图形宽度的检测方法，包括如下步骤：
接收触摸设备发送的触摸图形的第一坐标信息及其相应的触摸宽度信息，并保存所述第一坐标信息和触摸宽度信息；
接收操作系统发送的当前触摸图形的第二坐标信息；其中，所述第二坐标信息为触摸设备向操作系统发送的触摸图形坐标信息；
在保存的第一坐标信息中查找与所述第二坐标信息一致的第一坐标信息，将查找到的第一坐标信息所对应的触摸宽度信息确定为当前触摸图形的宽度信息。
上述触摸图形宽度的检测方法中，需要获取触摸图形触摸信息的应用软件 可以直接从触摸设备通过相关软件发送的第一坐标信息及其相应的触摸宽度信息，还可以通过相应的操作系统获取上述当前触摸图形的第二坐标信息，根据操作系统发送的第二坐标信息查找相应的第一坐标信息，从而进行触摸图形宽度信息的检测，使应用程序在通过操作系统获取第一坐标信息，以更容易做出业务层面响应动作的基础上，简化相应触摸宽度信息的检测过程，保证了触摸图形所对应的触摸信息的获取效果。
在一个实施例中，上述接收触摸设备发送的触摸图形的第一坐标信息及其相应的触摸宽度信息的过程可以包括：
通过安装在操作系统上的中转服务程序，从触摸设备获取触摸图形的第一坐标信息及其相应的触摸宽度信息。

具体实施方式
下面结合附图对本发明的触摸图形宽度的检测方法和系统的具体实施方式作详细描述。
参考图1，图1所示为一个实施例的触摸图形宽度的检测方法流程图，包括如下步骤：
S10，接收触摸设备发送的触摸图形的第一坐标信息及其相应的触摸宽度信息，并保存所述第一坐标信息和触摸宽度信息；
上述步骤S10中，触摸设备可以对用户通过相关触摸操作向其输入的触摸图形进行相关读取，以得到触摸图形的第一坐标信息和触摸宽度信息，并将上述第一坐标信息和触摸宽度信息直接发送至应用程序。
参考图2，上述触摸图形可以如图2所示触摸设备201上的图形202，也可以如触摸设备201上的图形203，上述触摸图形202可以为用户手指在相应触摸屏上滑动的图形，上述触摸图形203可以为用户通过手掌向触摸设备201所输入的图形。
上述第一坐标信息可以包括触摸图形所对应的封闭几何图形的中心坐标值，第一坐标信息相应的触摸宽度信息包括同一个触摸图形所对应的封闭几何图形的外接矩形的长和宽等信息，也可以包括上述触摸图形所对应的封闭几何图形的内接椭圆的长轴信息和短轴信息等。
保存上述第一坐标信息和触摸宽度信息时，需要对第一坐标信息及其相应的触摸宽度信息对应保存，一个第一坐标信息唯一对应一个触摸宽度信息，根据某个第一坐标信息可以在存储空间准确检测到相应的触摸宽度信息。可以建立相应的表格对上述第一坐标信息和触摸宽度信息进行保存，以提高后续查找和检测的便利性。
S20，接收操作系统发送的当前触摸图形的第二坐标信息；其中，所述第二坐标信息为触摸设备向操作系统发送的触摸图形坐标信息；
上述第二坐标信息可以包括触摸图形所对应的封闭几何图形的中心坐标值，同一个触摸图形的第一坐标信息和第二坐标信息是一致的。触摸设备获取当前触摸图形的坐标信息后，将上述坐标信息发送至操作系统，操作系统再将上述坐标信息发送至应用程序，即应用程序所接收的第二坐标信息。上述操作系统可以包括Windows系统、Linux系统以及OSX系统等。
S30，在保存的第一坐标信息中查找与所述第二坐标信息一致的第一坐标信 息，将查找到的第一坐标信息所对应的触摸宽度信息确定为当前触摸图形的宽度信息。
作为一个实施例，同一个触摸图形的坐标信息和触摸宽度信息的传输示意图可以如图3所示，触摸设备在获取触摸图形的坐标信息和触摸宽度信息后，将坐标信息和触摸宽度信息发送至应用程序，相应地，应用程序接收上述坐标信息和触摸宽度信息，得到第一坐标信息及其相应的触摸宽度信息；触摸设备还将上述触摸图形的坐标信息发送至操作系统，操作系统再将其接收的坐标信息(第二坐标信息)发送至应用程序；使应用程序可以直接处理操作系统转发的坐标信息，以得到应用程序编程框架的支持。
这样相比于直接处理触摸设备发送至应用程序的相关数据，应用程序在收到操作系统转发的坐标信息时可以更容易地做出业务层面的响应动作。且操作系统只转发触摸图形的坐标信息，而不转发相应的触摸宽度信息，使操作系统转发的数据量可以尽量小，以提高相应的转发效果。应用程序在接收操作系统转发的第二坐标系统后，既能简单地做出业务层面的响应，又能根据上述第二坐标信息在存储空间通过查找、检测等处理过程，获取到完整的触摸信息(包括上述第二坐标信息对应的第一坐标信息及触摸宽度信息)。
本发明提供的触摸图形宽度的检测方法中，需要获取触摸图形触摸信息的应用软件可以直接从触摸设备通过相关软件发送的第一坐标信息及其相应的触摸宽度信息，还可以通过相应的操作系统获取上述当前触摸图形的第二坐标信息，根据操作系统发送的第二坐标信息查找相应的第一坐标信息，从而进行触摸图形宽度信息的检测，使应用程序在通过操作系统获取第一坐标信息，以更容易做出业务层面响应动作的基础上，简化相应触摸宽度信息的检测过程，保证了触摸图形所对应的触摸信息的获取效果。
在一个实施例中，上述接收触摸设备发送的触摸图形的第一坐标信息及其相应的触摸宽度信息的过程可以包括：
通过安装在操作系统上的中转服务程序，从触摸设备获取触摸图形的第一坐标信息及其相应的触摸宽度信息。
本实施例中，在操作系统设置收发第一坐标信息及其相应的触摸宽度信息 的中转服务程序，触摸设备先将第一坐标信息及其相应的触摸宽度信息发送至中转服务程序，再由上述中转服务程序转发至相应的应用程序，这样通过上述中转服务程序进行相应的中转，可以实现触摸设备与应用程序的解耦。
在一个实施例中，上述保存所述第一坐标信息和触摸宽度信息的过程可以包括：
根据所述第一坐标信息和触摸宽度信息建立触摸信息集合；
建立触摸信息表；
将所述触摸信息集合存入所述触摸信息表。
上述触摸信息集合包含一组相对应的第一坐标信息和触摸宽度信息，在应用程序的存储空间查找到某触摸信息集合，便可以获取其中的第一坐标信息和触摸宽度信息，可以提高根据第一坐标信息检测触摸宽度信息的效率。建立触摸信息表，可以使各个包括第一坐标信息和触摸宽度信息的触摸信息集合有序的存入上述触摸信息表中，使触摸信息集合更容易被查找。
作为一个实施例，上述在保存的第一坐标信息中查找与所述第二坐标信息一致的第一坐标信息，将查找到的第一坐标信息所对应的触摸宽度信息确定为当前触摸图形的宽度信息的过程可以包括：
将第二坐标信息触摸信息表中的各个第一坐标信息进行比对，获取与所述第二坐标信息一致的第一坐标信息；
在所述第一坐标信息对应的触摸信息集合中读取触摸宽度信息；根据所述触摸宽度信息确定当前触摸图形的宽度信息。

本实施例中，建立数据字典保存上述第一坐标信息和触摸宽度信息，有利于后续对第一坐标信息的查找。由于第一坐标信息和第二坐标信息在获取过程中可能存在相关误差，导致上述第一坐标信息和第二坐标信息合理的偏移触摸图形对应的坐标信息，因此与第二坐标信息距离值小于预设阈值的第一坐标信息便为与上述第二坐标信息一致的第一坐标信息，以提高查找上述第一坐标信息的效率。上述预设阈值可以根据触摸设备的尺寸和分辨率等因素进行设置，比如设置为1、0.5等值。
在一个实施例中，上述触摸图形宽度的检测方法还可以包括
删除已查找到的触摸宽度信息以及相应的第一坐标信息，释放所述触摸宽度信息以及第一坐标信息所占的存储空间。
本实施例在检测到应用程序所需要的触摸宽度信息后，对上述触摸宽度信息以及相应的第一坐标信息进行删除，可以释放所述触摸宽度信息以及第一坐标信息所占的存储空间，以提高相应应用程序的效率。
在一个实施例中，上述接收触摸设备发送的触摸图形的第一坐标信息及其相应的触摸宽度信息的过程之前还可以包括：
分别利用串口设置与触摸设备之间的第一通信链路以及与操作系统之间的第二通信链路；其中，所述第一通信链路用于接收触摸设备发送的第一坐标信息及其相应的触摸宽度信息；所述第二通信链路用于接收操作系统发送的第二坐标信息。

本实施例利用串口进行相应信息的传输，可以保证所传信息的稳定性。
在一个实施例中，上述触摸宽度信息可以包括触摸图形所对应的内接椭圆的长轴信息和短轴信息。
本实施例采用触摸图形所对应的内接椭圆对上述触摸图形进行修正，可以使获取触摸宽度信息的内接椭圆全部落入用户的触摸区域，且可以尽量大的覆盖相应的触摸图形，以保证所获取的触摸宽度信息的准确性；上述触摸宽度信息可以表示为(w，h)；其中，w表示所述内接椭圆的长轴长，h表示所述内接椭圆的短轴长；根据上述内接椭圆的长轴信息和短轴信息，可以获取触摸图形的面积、尺寸等信息，进而可以根据触摸图形的面积、尺寸等信息进行相应的识别。上述长轴信息和短轴信息中的单位可以为像素。
在一个实施例中，上述触摸宽度信息可以包括触摸图形所对应的外接矩形的长和宽。
