一起工作的用户需要关于其合作环境的充分信息：关于其他组成员的存在和活动，关于共享的工件，等等。在CSCW文献中，已经提出了提供这种群体意识信息的几个概念、原型和系统。一般来说，它们从环境中捕获信息，对其进行处理，并将其呈现给用户。本文从处理方面进行论述；特别地，我们提出了一种利用感知语境处理感知信息的概念。有了这个概念，我们解决了事件通知的上下文化问题，以便在适当的用户情况下显示通知。我们描述了一个轻量级模型及其与事件和通知基础设施的集成。本文对一项实证研究进行了报道，并对合作环境下情境感知的设计提出了一些建议。
Users who work together require adequate information about their cooperative environment: about other group members’ presence and activities, about shared artefacts, etc. In the CSCW literature several concepts, prototypes, and systems for providing this group awareness information have been presented. In general, they capture information from the environment, process it, and present it to the users. This paper addresses the processing aspect; in particular, we present a concept for processing awareness information by means of awareness contexts. With this concept we address the problem of contextualising event notifications enabling the presentation of notifications in the appropriate user situation. We describe a lightweight model and its integration into an event and notification infrastructure. We report on an empirical study, and draw some conclusions for the design of context-awareness for cooperative environments.
