As the user's activity and location are crucial for many applications, context awareness has been focused more deeply in the research fields of location awareness and activity recognition.

上下文感知系统关注上下文的获取(例如:。使用传感器来感知一个场景) ，对场景的抽象和理解(例如:。将感知到的感官刺激与上下文进行匹配) ，以及基于识别上下文的应用行为(例如:。根据上下文触发动作)。由于用户的活动和位置对于许多应用来说都是至关重要的，因此上下文感知在位置感知和活动识别等领域得到了越来越深入的研究。

Context awareness is used to design innovative user interfaces, and is often  used as a part of ubiquitous and wearable computing. It is also beginning to be felt in the internet with the advent of hybrid search engines.

define human factors and physical environment as two important aspects relating to computer science. More recently, much work has also been done to ease the distribution of context information; Bellavista, Corradi, Fanelli & Foschini survey the several middleware solutions that have been designed to transparently implement context management and provisioning in the mobile system. Grifoni, D'Ulizia & Ferri  provided a review of several context-aware location-based service systems using big data by analysing the methodological and practical choices that their developers made during the main phases of the context awareness process (i.e. context acquisition, context representation, and context reasoning and adaptation). Perera, Zaslavsky, Christen, & Georgakopoulos have performed a comprehensive survey on context-aware computing from Internet of Things perspective by reviewing over 50 leading projects in the field. Further, Perera has also surveyed a large number of industrial products in the existing IoT marketplace from context-aware computing perspective. Their survey is intended to serve as a guideline and a conceptual framework for context-aware product development and research in the IoT paradigm. The evaluation has been done using the theoretical framework developed by Dey and Abowd (1999) more than a decade ago. The combination of the Internet and emerging technologies transform everyday objects into smart objects that can understand and react to their contexts.

上下文感知被认为是普适计算系统的一种使能技术。上下文感知被用来设计创新的用户界面，并且常常作为普适和可穿戴计算的一部分使用。随着混合搜索引擎的出现，互联网也开始感受到这一点。施密特、贝格尔和盖勒森将人的因素和物理环境定义为与计算机科学有关的两个重要方面。最近，在简化上下文信息的分发方面也做了很多工作，贝亚维斯塔、 Corradi、 Fanelli 和 Foschini 调查了几个中间件解决方案，这些中间件解决方案旨在透明地在移动系统中实现上下文管理和配置。Grifoni，d’ulizia & Ferri 通过分析开发人员在上下文意识过程的主要阶段(即:。上下文获取、上下文表征、上下文推理和顺应)。Perera，Zaslavsky，Christen，和 Georgakopoulos 从物联网的角度对上下文感知计算进行了全面的调查，回顾了该领域50多个主要项目。此外，佩雷拉还从上下文感知计算的角度调查了现有物联网市场中的大量工业产品。他们的调查旨在为物联网范式下的环境意识产品开发和研究提供指导和概念框架。评价是利用10多年前由 Dey 和 Abowd (1999)开发的理论框架进行的。互联网和新兴技术的结合将日常物品转化为智能物品，可以理解和反应它们的环境。

Human factors related context is structured into three categories: information on the user (knowledge of habits, emotional state, biophysiological conditions), the user's social environment (co-location of others, social interaction, group dynamics), and the user's tasks (spontaneous activity, engaged tasks, general goals). Likewise, context related to physical environment is structured into three categories: location (absolute position, relative position, [[wikt:colocation|co-location]]), infrastructure (surrounding resources for computation, communication, task performance), and physical conditions (noise, light, pressure, air quality).<ref>[https://link.springer.com/article/10.1007%2Fs11042-010-0711-z?LI=true A Comprehensive Framework for Context-Aware Communication Systems.
