协同环境中3D替身交互行为动态控制的实现

Realization of Dynamic Control of the Interactive Actions among Users in the Collaborative Virtual Environment

协同环境中用户之间的协同感知程度和实时交互性直接影响到协同工作的质量。目前,部分CSCW 应用系统通过向虚拟协同环境CVEs 中添加3D 替身来提高用户之间的协同感和交互感。但经研究发现,其场景中所有的替身只是在用户的控制下机械地使用VRML 中提供的行为机制进行运动,替身之间也不存在交互行为,用户交互程度仍然不足。为了进一步解决这个问题,笔者着重研究了CVEs 中3D 替身之间交互行为的实现,通过替身行为机制的建立,利用VRML 和Java 实现了替身之间交互行为的动态控制,从而增强了用户的协同感和交互感,提高了协同工作的效率。

The interaction and collaboration among users in the collaborative environment determine the quality of collaborative work. At present, in some CSCW application systems the way by adding 3D avatars into the CVEs to improve the interaction and collaboration has been advanced. But after study, we found that all the avatars can only use the actions provided by VRML player to move within the CVEs under the commands ordered by the users, and there is no interaction among avatars, so the interaction degree is still not enough. In order to solve this problem farther, the realization of interaction among 3D avatars has been discussed in this paper. By setting up an action mechanism of avatars, its dynamic control has been realized by combining VRML and Java together. So the interaction and collaboration among users have been enhanced and the efficiency of collaborative work has been improved.
