基于ARINC661的多点触控手势数据提取算法

Multi-touch Gesture Data Extraction Algorithm Based on ARINC661

为解决ARINC661规范下多点触控手势数据量大、识别效率低,难以准确定位到相关窗体部件的问题,提出一种多点触控手势数据提取算法。根据ARINC661规范,进行多点触控触点数据和手势数据提取算法设计,对原始数据进行预检测、标准化处理,将单点触控手势数据与多点触控手势数据统一化处理,根据触点定位相关窗体部件。测试结果表明:该算法合理可行,软件运行可靠,所提取的触控手势数据能为手势识别提供依据。

In order to solve the problem that the multi-touch gestures under the ARINC661 specification have large data volume and low recognition efficiency,and it is difficult to accurately locate the relevant window components,a multi-touch gesture data extraction algorithm is proposed.According to the ARINC661 specification,the multi-touch contact data and gesture data extraction algorithm are designed,the original data is pre-detected and standardized,and the single-touch gesture data and the multi-touch gesture data are unified,according to the contacts locate relevant widget part.The test results show that the algorithm is reasonable and feasible,and the software runs reliably.The extracted touch gesture data can provide a basis for gesture recognition.
