无编辑摘要
Context awareness refers, in information and communication technologies, to a capability to take into account the situation of entities, which may be users or devices, but are not limited to those. Location is only the most obvious element of this situation. Narrowly defined for mobile devices, context awareness does thus generalize location awareness. Whereas location may determine how certain processes around a contributing device operate, context may be applied more flexibly with mobile users, especially with users of smart phones. Context awareness originated as a term from ubiquitous computing or as so-called pervasive computing which sought to deal with linking changes in the environment with computer systems, which are otherwise static. The term has also been applied to business theory in relation to contextual application design and business process management issues.

在信息和通信技术中，情景感知是指一种考虑实体（包括但不限于用户或设备）所处情形的能力，其中，位置只是实体所处情形中最明显的因素。对于移动设备而言，情景感知一般是指对其位置信息的感知。尽管位置决定某个设备周围的某些过程如何运作，但情景一以更灵活地应用于移动用户，特别是智能手机用户。情景感知起源于普适计算，它试图处理环境变化与计算机系统之间的联系，否则计算机系统是静态的。这个术语也被应用到与情景应用程序设计和业务流程管理问题相关的业务理论中。
