MDE-VR:面向虚拟现实的多显示环境

摘要

针对目前虚拟现实领域缺乏可用的中间框架对底层MDE和高层的本地协同工作模式进行支持这一问题,设计并实现了一个多显示环境下基于虚拟现实的系统框架MDE-VR;基于该框架提出了一种多显示环境下的本地协同工作机制,组合了空间无缝交互技术和空间内聚交互技术两种不同的交互技术,方便用户操纵公共显示屏幕;最后开发了一个系统原型能够有效支持面向虚拟现实的同一地点的多人协同工作.实验结果表明了提出的MDE-VR框架和交互技术的可用性.%In order to solve the problem of lacking of middle software to support upper collaborative working pattern and lower multidisplay environment in the field ofvirtual reality, a Multi-Display environment framework for virtual reality is proposed. The framework defines co-located collaborative working mechanism in multi-display environment by grouping displays into public and private ones and two kinds of interaction techniques called spatial seamlessness interaction and spatial cohesion interaction are integrated in this framework.At last a system based on MDE-VR is developed to support multi-user co-located collaborative working. The experimental results show the feasibility of MDE-VR and the two kinds of interaction technologies.
