上下文感知是泛在计算环境中令人兴奋的研究课题之一，它有望通过使用传感器和执行器来创造一些新的业务和/或服务。特别是，来自网络空间的上下文信息允许系统在时间和空间上扩展其信息空间。然而，许多应用并没有将网络空间的语境信息作为将来时的信息源。这使得应用程序无法意识到各种各样的上下文。我们开发了一个系统软件“ContextDistillery”，它使应用程序开发人员能够增量地获取上下文信息，而无需考虑描述性信息、元上下文信息。接下来，我们构建了一个应用程序“带我一起去！”，它体现了物理/网络空间集成的概念。本文报告了一个应用程序开发的案例研究。讨论了通过应用程序开发的结果。在此基础上，提出了一种实现更实用的上下文感知概念的架构。
Context-awareness is one of the exciting research topics in a ubiquitous computing environment, which is expected to create some new business and/or services by using sensors and actuators. Especially, context information from cyber space allows a system to extend its information space both temporalily and spatially. However, many applications do not regard context information from cyber space as a information source of future tense. This keeps applications from being aware of a wide variety of context.We have developed a system software "ContextDistillery", which enables an application developer to obtain context information incrementally without taking account of descriptive information, meta-context information. Next, we have built an application "Take me with you!", which exemplifies the notion of physical/cyber space integration.This paper reports a case study of the application development. Discussions of findings through the application development are presented. Moreover, an architecture for realizing more practical notions of context-awareness is introduced based on the discussions.
