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。
Computer-Supported Collaborative Work CSCW (collaborative awareness) is the basis for natural interaction. Currently, no collaborative awareness model is available for all CSCW applications. For synchronous collaborative application system, a role-based hierarchical collaborative perception model is proposed. By decomposing / merging the role map, the collaborative perception is divided into four levels, on the basis of which, the perceptive intensity is accurately quantified according to the spatial location relationship and the correlation degree of the collaboration task. According to the value of perceived intensity, collaborative virtual groups can be dynamically set up to transmit awareness information on demand in the virtual group, thereby reducing the information flow of the network and improving the cooperation efficiency.
