摘要

使用上下文作为输入是普适计算系统的主要特征之一。我们研究了普适计算环境中上下文的结构和系统特征,以及它们对上下文计算和上下文感知应用程序设计的可能影响。我们给出了一个关于上下文理解的定义,以及它是如何在系统层面上推导出来的。上下文交互由一个消费者-生产者模式来研究,该模式为工件之间的上下文交换建模。效度、相关性、信度和语境历史作为语境的相关系统属性被识别和讨论。

Towards a better understanding of context attributes
The use of context as an input is one of the major characteristics of ubiquitous computing systems. We look into the structural and the systematic features of context in ubiquitous computing environments and their possible influence on context computing and the design of context-aware applications. We give a definition regarding an understanding of context and how it is derived at a systematic level. Context interaction is investigated by a consumer-producer schema that models the exchange of context among artefacts. Validity, relevance, reliability and context history are identified and discussed as relevant systematic attributes of context.
