| 摘 要： | 计算机支持的协同工作CSCW(computer-surpport-edcooperativework)中协作感知(collaborativeawareness)是自然交互的基础,目前没有一种协作感知模型能适用于所有的CSCW应用领域。针对同步协作应用系统,提出了一种基于角色的层次型协作感知模型。通过对角色任务图的分解/合并,将协作感知划分为4种层次,在此基础上根据空间位置关系和协作任务相关度精确量化了感知强度。依据感知强度值,可以动态地组建协作虚拟组,在虚拟组内按需传输感知信息,从而减少网络的信息流通量,提高协作效率。

| Abstract: | Collaborative awareness is the basis of natural interactions, but there is no collaborative awareness model applicable to all computer-surpported cooperative work (CSCW) applications. A role-based hierarchical collaborative awareness model developed for synchronous cooperative applications divides the awareness information into four levels by decomposition and recombinations using a role-task graph. The relationships between tasks and places where the objects are manipulated are used to precisely calculate the strength of awareness. The strength of awareness is then used to dynamically establish a cooperative virtual team. The awareness messages within the virtual team can be sent selectively based on specified requirements. Therefore, the network traffic is controlled and the overall efficiency of the cooperative work is improved. |
