普适计算与传统分布式计算的区别之一是上下文。上下文，如时间，位置和情况，允许系统适应当前的环境，以促进计算环境的使用。在本文中，我们提出了一个无处不在的计算应用程序，是上下文感知的文件系统。上下文用于支持无处不在的计算空间中的应用程序和设备类型。该系统的新功能包括数据视图如何适应当前正在执行的活动以及用户数据如何导入本地环境。我们的系统作为一个无处不在的计算基础设施的一部分，部署在一个研讨会室调查的性能，可扩展性和可用性的问题进行评估。
One of the factors that differentiates ubiquitous computing from traditional distributed computing is context. Context, such as time, location, and situation, allows a system to adapt to the current surroundings in order to facilitate the use of the computational environment. In this paper, we present a file system for ubiquitous computing applications that is context-aware. Context is used to support the types of applications and devices that are found in ubiquitous computing spaces. Novel features of the system include how the view of data adapts to the activity being currently performed and how user data is imported into the local environment. Our system is evaluated as part of a ubiquitous computing infrastructure deployed in a seminar room to investigate issues of performance, scalability, and usability.
