普适环境下基于映射的非对称协同感知

针对普适环境下参与协同设计的移动终端资源受限的特点,提出了非对称协同感知映射模型、机制和相应的共享工作空间逻辑一致性维持方法，提出了在共享工作空间视图中的3种拓扑映射：子图映射、顶点融合映射和路径简约映射。通过拓扑映射,使得在非对称映射中映射区域仅为资源受限端当前可能关注的内容,减少了协同感知所需资源，同时结合按需获取机制实现了视图感知的数据一致性维护。从而实现了普适环境下资源非对称终端有效协同设计。

Unsymmetrical collaborative awareness based on mapping in ubiquitous environment

In ubiquitous environment mobile sites join in collaborative design sessions and have limited resources. The unsymmetrical awareness mapping model, mechanism and related method for maintaining the logical consistency of shared workspace were presented. Three kinds of topology mapping in shared workspace, that is, subgraph mapping, vertex integration mapping and path compression mapping, were proposed. Based on topology mapping of the view, the mapped awareness regions were of much interest to users and the resources that collaborative awareness needs decreased. The data consistency was maintained by applying on demand awareness acquirement. Therefore, effective collaborative design which is composed of stations with unsymmetrical collaborative resources are realized in ubiquitous environment.
