上下文感知计算提出了根据用户的情况和环境进行调整的技术。在移动协作工作中，这种情况被视为一个重要因素，这里的情景感知试图通过几种方式促进协调。虽然已经进行了大量的研究，但对语境意识的定义仍然有很大的不同。除了对语境的定义不同外，大多数研究都没有区分复杂的语境信息和精确的传感器信息。了解到协作工作可以受益于一定程度的上下文感知，以及上下文感知对于无处不在的计算环境是必不可少的，本文专注于上下文感知应用程序的初始设计。在回顾以往语境分类模型的基础上，提出了语境信息模型。从用户的角度进行分类，该模型严格区分了上下文信息和传感器信息。然后举例说明了如何将该模型应用于实际的消费设备。本文的结论是，如果要为真实的协作和消费者环境开发情景感知计算应用程序，则应逐步纳入传感器措施，以包含对情景的简化分类，而不是详细定义情景。
Context-aware computing proposes technology that adapts according to the user’s situation and environment. Within mobile collaborative work the situation is viewed as an important factor, here context-awareness attempts to facilitate coordination in several ways. Although much research has been conducted, context-awareness is still defined very differently. Besides differing in definitions of context, most research fails to separate between complex context information and precise sensor information. Knowing that collaborative work can benefit from some degrees of context-awareness and that context-awareness is essential to a ubiquitous computing environment, this paper focuses on initial design of context-aware applications. After reviewing past categorization models of context, The Context Information Model is proposed. Categorizing from the user’s view point, the model separates strictly between context information and sensor information. It is then exemplified how the model can be applied to an actual consumer device. The paper concludes that if context-aware computing applications are to be developed for real collaborative and consumer settings, sensor measures should be gradually incorporated to comprise a simplistic categorization of context rather than define context in detail.
