In computer science ''context awareness'' refers to the idea that computers can both sense, and react based on their environment. Devices may have information about the circumstances under which they are able to operate and based on rules, or an intelligent stimulus, react accordingly. The term ''context awareness'' in ubiquitous computing was introduced by Schilit (1994).<ref name="schilit94">{{cite conference

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.

== Relational context : dynamic and non-user-centric definitions相关情景：动态的和去中心化的==

Whereas early definitions of context tended to center on users, or devices interfaced directly with users, the oft-cited definition from Dey<ref name="dey2001"/> ("''any information that can be used to characterize the situation of an entity''") could be taken without this restriction. User-centric context, as may be used in the design of [[human-computer interaction|human-computer interfaces]], may also imply an overly clearcut, and partially arbitrary,  separation between "content" (anything which is ''explicitly'' typed in by users, or output to them), and context, which is ''implicit'', and used for [[context adaptation|adaptation]] purposes. A more dynamic and de-centered view, advocated by Dourish <ref> Dourish, Paul. "What we talk about when we talk about context." Personal and ubiquitous computing 8.1 (2004): 19-30.</ref> views context as primarily ''relational''. This was originally congruent with the move from desktop computing to [[ubiquitous computing]], but it does also fit with a broader understanding of [[ambient intelligence]] where the distinctions between ''context'' and ''content'' become relative and dynamic.<ref> https://www.researchgate.net/publication/230704197_Ambient_Intelligence Streitz, Norbert A., and Gilles Privat. "Ambient Intelligence" , ''Universal Access Handbook'' (2009)</ref> In this view, whichever sources of information (such as [[Internet of Things|IoT]] sensors) may be ''context'' for some uses and applications, might also be sources of primary ''content'' for others, and vice versa. What matters is the set of ''relationships'' that link them, together and with their environment. Whereas early descriptions of single-user-centric context could fit with classical [[Entity-attribute-value model|entity-attribute-value models]], more versatile graph-based information models, such as proposed with [[NGSI-LD]], are better adapted to capture the more relational view of context which is relevant for the  [[Internet of Things]], [[Cyber-Physical Systems]] and [[Digital Twins]]. In this broader acceptation, context is not only represented as a set of attributes attached to an entity, it is also captured by a graph that enmeshes this entity with others. Context awareness is the capability to account for this cross-cutting information from different sources.

== 在情景与社交认知中的应用 ==

Context awareness has been applied to the area of [[computer-supported cooperative work]] (CSCW) to help individuals work and collaborate more efficiently with each other.  Since the early 1990s, researchers have developed a large number of software and hardware systems that can collect contextual information (e.g., location, video feeds, away status messages) from users.  This information is then openly shared with other users, thereby improving their situational awareness, and allowing them to identify natural opportunities to interact with each other.  In the early days of context-aware computing, many of the systems developed for this purpose were specifically designed to assist businesses or geographically separated work teams collaborate on shared documents or work artifacts.  More recently, however, there has been a growing body of work that demonstrates how this technique can also be applied to groups of friends or family members to help keep them apprised of each other's activities.

The most common context to obtain and share for the purposes of improving situational awareness is the user's location. In an early prototype, the Active Badge system, for example, each user had a uniquely identifying badge that could be tracked via a series of overhead infrared sensors.  As users walked throughout a building, their location was constantly monitored by a centralized server.  Other users could then view this information (either in text form, or on a map, as was done in later work) to determine if a user is in her office, thereby allowing them to determine the best time to stop by for an unplanned conversation.  Location was also shared in the PeopleTones, Serendipity, and the Group Interaction Support Systems to help users determine when they are near friends, users with shared personal interests, and teammates, respectively.  In comparison with Active Badge, which only displays location information, these systems are more proactive, and will alert the users when they are in proximity of each other.  This lets the user know when a potential interaction opportunity is available, thereby increasing his/her chances of taking advantage of it.

为了改善情势察觉，最常见的获取和分享情景就是用户的位置信息。例如，在早期的原型机 Active Badge 系统中^[21]，每个用户都有一个独特的识别标志，可以通过一系列的间接红外传感器来跟踪。当用户在建筑物中行走时，他们的位置信息会被一个集中的服务器持续监控。然后，其他用户可以查看这些信息(以文本形式或在地图上查看，像后来的研究那样^[22]) ，以确定用户是否在办公室，从而允许他们确定非预约访问的最佳时间。位置信息也在PeopleTones^[23]、 Serendipity ^[24]和 Group Interaction Support ^[25]系统中进行了共享，以帮助用户分别确定他们何时与朋友、有共同兴趣的用户和队友关系密切。与只显示位置信息的 Active Badge 相比，这些系统更加积极主动，当用户彼此靠近时会提醒他们。这样可以让用户知道什么时候有潜在的交互机会，从而增加他/她利用这个机会的机会。

Another popular context to share is a user's work activity, often by sharing video. In the Community Bar system, researchers developed a desktop application that periodically took screenshots of the user's display. This information was then shared with the user's co-workers so that they could know what documents/artifacts their teammates was working on, and provided a common frame of reference so that users could n talk about these artifacts as if they were collocated. In Montage, users are given the ability to remotely activate the webcam on another user's computer for a brief amount of time. This capability to "glance" at another user lets users see if they are busy or preoccupied, which in turn helps them better determine the most opportune time to initiate a conversation.

  systems also rely heavily on audio in order to determine if and when a user was potentially interruptible. Unlike Thunderwire, however, these systems rely on machine learning algorithms in order to analyze the user's audio and determine if the user is talking. This allows the system to provide other users with the same context (i.e., whether or not the user is in a conversation) without having to share the actual audio, thereby making it more privacy centric.

第三种可以分享以改进或增强情景识别的内容是用户的音频。在 Thunderwire ^[28]系统中，研究人员开发了一个只有音频的媒体空间，允许朋友们分享来自移动设备的麦克风的原始音频。这个系统本质上是一个永久性的电话会议，允许用户收听其他用户的音频，以确定他们是否以及何时参与了对话。WatchMe^[29] 和 ListenIn^[30] 系统还严重依赖音频，以确定用户是否以及何时可能被中断。然而，与 Thunderwire 不同的是，这些系统依赖于机器学习算法来分析用户的音频并确定用户是否在说话。这使得系统可以为其他用户提供相同的情景(例如，用户是否在对话中) ，而无需共享实际的音频，从而使其更加以隐私为中心。

Although these system demonstrate how context awareness can be used to support situational and social awareness, the long term effectiveness of these systems are not yet fully understood.  Many of the systems described above have only been evaluated at a conceptual level, or to demonstrate that the system is technically feasible.  Consequently, while initial results from these studies suggest that context awareness can support situational awareness tasks, more longitudinal data is required.

虽然这些系统展示了如何使用情景感知来支持情景和社会感知，但是这些系统的长期效果还没有尚未可知。上述许多系统只是在概念层面上进行了评估，或只证明该系统在技术上是可行的。因此，虽然这些研究的初步结果表明，情景感知可以支持情势察觉任务，但还需要更多的纵向数据。
