摘要
OSG多点触控自然用户接口框架是在Windows多点触控技术基础上,将触控事件的管理和处理与OSG的事件处理机制相结合,形成了OSG的多点触控运行框架.在与用户交互过程中产生手指触屏的原始数据,根据这些原始数据定义所需的手势,并将其与OSG中交互事件处理机制相结合,完成利用多点触控对三维场景的交互操作.基于以上原理,分析了三维用户交互中主要的操作任务,定义了符合三维空间操作认知的多点触控交互手势,设计了相关手势的识别算法,并通过实例应用的开发验证了这一原理和设计成果的正确性和可行性.
OSG multi-touch natural user interface framework is based on the Windows multi-touch technology, in which the management and processing of touch event combines with OSG event processing mechanism, and forms the OSG multi-touch operation framework. According to the raw data that is produced by user＇s finger through touching screen, it defines the gestures needed, and combines it with interactive event processing in OSG to complete multi-touch for interactive operation in 3d scene. Based on the above framework, this paper analyzes the major operation tasks in 3D user interaction, defines the interactive gestures that conform to cognition of the 3D spatial operations, and designs the recognition algorithm of the related gestures. Finally, through developing an application example, the correctness and feasibility of design and cognition of multi-touch natural user interface framework in OSG are verified.
