中文摘要：

提出一种面向协作交互任务的资源模型．首先分析了现有协作任务分析方法和资源模型；然后在总结典型协作交互任务的基础上，提出了基于分布式认知的协作资源模型，描述了模型的组成结构和交互策略；最后给出了模型的使用模式和一个基于此模型的笔式协作概念图实例．分析表明，该模型能有效地支持协作交互，建立符合认知特点的协作用户界面．

英文摘要：

A resource model for collaborative interaction tasks is proposed in the paper. First, we discuss the current collaborative task analysis methods and resource models. Then, we propose the resource model for collaboration and describe its framework and interaction strategy. Finally, we show how to use the model by presenting a pen-based collaborative concept mapping system. The model can support collaborative interaction well, and it helps design collaborative user interfaces in accordance with human＇s cognition.
