基于知识的CSCW人机接口模型

A KNOWLEDGE-BASED HUMAN-COMPUTER INTERACTION MODEL FOR CSCW SYSTEMS

人机接口是ＣＳＣＷ系统的重要组成部分，也是它的难点之一．本文针对ＣＳＣＷ系统中用户动作的协同特性，提出了一种协同人机接口结构模型ＫＣＨＣＩ，通过对用户动作的多层抽象和对动作结果的多层例化，实现多用户之间的多层次协同及感知，同时，以知识作为规范描述语言，不仅增强了接口的灵活性，提高了接口的协同效率，也方便了接口的开发．

Human-computer interface is an important and difficult component of CSCW systems. In this paper, a model of cooperative human-computer interface is proposed according to the cooperative characteristics of user actions in CSCW systems. It deifies user actions and realizes the results of the actions to implement multi-level collaboration among multiple users. Furthermore, using knowledgeas specifications in the model enhances the interface flexibility, improves the cooperation efficiency and facilitates the interface development.
