三维交互体系结构的研究与实现

RESEARCH AND IMPLEMENTATION OF INTERACTIVE 3D ARCHITECTURE

针对当前人机交互特别是三维交互的现状基于分布式环境提出了一个分层的模型结构 ,分析了一般交互在各层中的基本行为 ,建立了与具体硬件设备无关的面向任务的事件模型 ,着重讨论了原始结构形成基本事件的方法 ,复合事件对基本事件的时间关系的整合以表达复杂的语义 .在一般交互模型的基础上描述了三维交互的 8种基本任务 ,一切复杂的交互任务都是这 8种基本任务在时间或空间上的语义整合 .最后实现了分布环境下三维交互的一个原型系统 Easy3D.

A hierarchical model is presented based on current human computer interaction and 3D interaction especially.The basic behaviors are analysed and an event model independent of devices is constructed.The event model embodies the ways in which the origin structures form the basic events and the basic events form the composite events to describe the more complicate semantic. Based on the general interaction model, the eight tasks on which any complicate task can be represented in 3D interaction are described and implemented in Easy3D, the prototype system.
