Context-aware devices may also try to make assumptions about the user's current situation. Dey (2001) define context as "any information that can be used to characterize the situation of an entity."

在计算机科学中，上下文感知指的是计算机既能感知环境，又能根据环境做出反应。设备可能知道在什么情况下它们能够按照规则或智能刺激进行操作，从而做出相应的反应。语境意识这个术语在《普适计算由 Schilit 引入(1994)。上下文感知设备也可能尝试对用户的当前情况进行假设。Dey (2001)将上下文定义为“可用于描述实体状况的任何信息”

在计算机科学中，情景感知指的是计算机既能感知环境，又能根据环境做出反应。设备知道在什么情况下它们能够按照规则或智能刺激进行操作，从而做出相应的反应。在普适计算领域， Schilit 在1994年首次将情景感知引入普适计算领域。情景感知设备也可以尝试对用户的当前情况进行假设。Dey (2001)将情景定义为“可用于描述实体状况的任何信息”。

While the computer science community initially perceived the context as a matter of user location, as Dey discuss,<ref name="dey2001"/> in the last few years this notion has been considered not simply as a state, but part of a process in which users are involved; thus, sophisticated and general context models have been proposed (see survey<ref name="curino-context2007">{{cite journal

For example: a context-aware mobile phone may know that it is currently in the meeting room, and that the user has sat down. The phone may conclude that the user is currently in a meeting and reject any unimportant calls.

虽然计算机科学界最初认为上下文是一个用户位置的问题，正如 Dey 所讨论的，在过去几年中，这个概念不仅被认为是一个状态，而是一个过程的一部分，用户参与其中; 因此，复杂和一般的上下文模型已经被提出(见调查) ，以支持上下文感知应用程序，使用它们(a)适应接口，(b)定制应用相关数据集，(c)提高信息检索的精度，(d)发现服务，(e)使用户隐式交互，或(f)构建智能环境。例如: 上下文感知的移动电话可能知道它当前在会议室，并且用户已经坐下。电话可能会断定用户当前正在开会，并拒绝任何不重要的电话。

Context-aware systems are concerned with the acquisition of context (e.g. using sensors to perceive a situation), the abstraction and understanding of context (e.g. matching a perceived sensory stimulus to a context), and application behaviour based on the recognized context (e.g. triggering actions based on context).<ref name="schmidt2003phd">{{cite conference
