许多上下文感知服务都假设它们使用的上下文是完全准确的。然而，在现实中，感知到的和解释的上下文常常是模棱两可的。因此，开发现实且可部署的上下文感知服务面临的挑战是处理模糊上下文的能力。尽管某些歧义可以使用自动技术来解决，但我们认为正确处理歧义上下文通常需要用户的参与。我们使用术语“中介”来指代用户和系统之间发生的对话。在本文中，我们描述了一种支持构建上下文感知服务的架构，该服务假设上下文不明确，并允许移动用户在感知环境中调解歧义。我们提出了因支持空间和时间上的中介而产生的设计指南，这些问题在过去通常使用中介的图形用户界面领域中不存在。我们说明了我们的架构的使用，并通过示例上下文感知应用程序（单词预测器系统）对其进行了评估。
Many context-aware services make the assumption that the context they use is completely accurate. However, in reality, both sensed and interpreted context is often ambiguous. A challenge facing the development of realistic and deployable context-aware services, therefore, is the ability to handle ambiguous context. Although some of this ambiguity may be resolved using automatic techniques, we argue that correct handling of ambiguous context will often need to involve the user. We use the term mediation to refer to the dialogue that ensues between the user and the system. In this article, we describe an architecture that supports the building of context-aware services that assume context is ambiguous and allows for mediation of ambiguity by mobile users in aware environments. We present design guidelines that arise from supporting mediation over space and time, issues not present in the graphical user interface domain where mediation has typically been used in the past. We illustrate the use of our architecture and evaluate it through an example context-aware application, a word predictor system.
