协同虚拟环境分层协作感知模型研究

Research on hierarchical collaborative awareness model on CVE

协作感知是协同虚拟环境用户协作和交互的基础,目前没有一种协作感知模型适用于所有虚拟协作应用。介绍了协同虚拟环境和协作感知的定义,分析了协同虚拟环境中用户协作过程和任务关系,引入角色理论和Agent技术对协同虚拟环境和协作者的操作权限进行表示,通过对角色任务图分解/合并划分协作感知层次,建立协作感知模型量化计算感知强度,动态组建协作虚拟组,提高通信效率。

Collaborative awareness is the basis of collaborative activities and natural interactions for users in collaborative virtual environment, However, there＇s no collaborative awareness model suitable for all virtual cooperative applications. Collaborative awareness and the relationships of collaborative processes and tasks in CVE are discussed firstly. Role schemes and Agent technology are applied to establish more efficient mechanism to support roles and rights management in CVE. By dividing awareness information into four levels, awareness strength is precisely calculated by decomposition and recombination using a role-task graph to dynamically establish cooperative virtual teams in this model.
