What is meant by context in pervasive computing?
(Learn how and when to remove this template message) Context-aware computing refers to a general class of mobile systems that can sense their physical environment, and adapt their behavior accordingly. Three important aspects of context are: where you are; who you are with; and what resources are nearby.
What is context in IoT?
A key ingredient in rich IoT interactions is context. Contexts can be defined as information that can be used to characterize the situation of entities or processes in a system [1]. The term context-awareness refers to the system's ability to use context information [1].
What do you mean by context-aware computing?
Context-aware computing is a style of computing in which situational and environmental information about people, places and things is used to anticipate immediate needs and proactively offer enriched, situation-aware and usable content, functions and experiences.
What is context in mobile computing?
Context represents any information that can be used to characterize the situation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and application themselves.
What is the meant by context?
Definition of context 1 : the parts of a discourse that surround a word or passage and can throw light on its meaning. 2 : the interrelated conditions in which something exists or occurs : environment, setting the historical context of the war.
What is context with example?
Context means the setting of a word or event. If your friend is furious at you for calling her your worst enemy, remind her that the context of those remarks was Opposite Day. Context comes from the Latin for how something is made.
What is context in communication?
Contextual communication is defined as the bidirectional transfer of information between two parties, where both sides are aware of the relational, environmental, and cultural context of the exchange. Simply put, it means that all entities involved know what the conversation is about.
What is context interaction?
The interaction context refers to the micro-level of context around the interaction between the user and the product (e.g., interaction of the user with the television, of the user with the other people watching the game and the home environment).
What is context and when is a system context-aware?
A context-aware system may be defined as a system that can understand the context of a given situation and either share this context with other systems for their response or respond by itself. Context has many definitions such as additional information that further describes a given situation.
What is context and its types?
Context can take many forms, including background information or details about the circumstances, environment, or timeframe in which a work takes place. The defining characteristic of context is that it helps to clarify the meaning of a work of writing.
What is context and constraints?
Contextual constraint has been described as the extent to which the sentence yields a particular word as the completion of the phrase (Schwanenflugel & LaCount, 1988. (1988). Semantic relatedness and the scope of facilitation for upcoming words in sentences.
What is context of data?
Data context is the network of connections among data points. Those connections may be created as metadata or simply identified and correlated. Contextual metadata adds value, essentially making it possible to receive information from data. A single data point on its own is useless.
What is context and its types?
Context can take many forms, including background information or details about the circumstances, environment, or timeframe in which a work takes place. The defining characteristic of context is that it helps to clarify the meaning of a work of writing.
What is context in artificial intelligence?
Contextual AI is technology that is embedded in and understands human context and is capable of interacting with humans. In this article, I'll explore how contextual AI works, how it compares to previous phases of AI, the challenges we need to overcome, and the progress we're making at Adobe.
What is product context?
The context of a product is the circumstances or setting in which an object is used, and which add to its meaning. A customer's satisfaction with a product depends on the context of its use.
What is context in design?
What is context in design? Context is a term used in design to refer to the circumstances, background, or environment in which a person, thing, or idea exists or occurs.
Abstract
Context and context-awareness provides computing environments with the ability to usefully adapt the services or information they provide.
1. Introduction
Weiser's [38] vision of ubiquitous computing, with its invisible yet attentive computing environment, providing the right information to the right person at the right time, is an exciting vision of how to evolve computer technology.
2. Existing context-awareness approaches
One of the earliest descriptions of context and context-aware applications was proposed by Ref. [30] and was based on their experiences with the PARCTAB system [29], [37].
3. Activity-centric context
This section discusses a slightly different view of context, the activity-centric view, which focuses on the context that surrounds the performance of an activity by an agent. This view of context may be more suitable for the development of context-aware applications to support complex cognitive activities.
4. Developing context-aware applications
The computational environment needed to support the activity-centric view of context could be some kind of smart room, ubiquitous computing, or even desktop computing environment.
5. Conclusions and future work
This paper has presented a conceptual model of context, based around an agent's performance of an activity.
What Is Ubiquitous Computing?
Origins of Ubiquitous Computing
- The origins of ubiquitous computing can be traced to the late 1980s. Around the year 1988, Mark Weiser, who was employed as the Chief Technologist of the Xerox PARC (Palo Alto Research Center), coined the term ubiquitous computing. He wrote some of the earliest papers on the subject, including some with the PARC Director and Chief Scientist John Seely Brown. Weiser is …
Key Features of Ubiquitous Computing
- Let us look at some of the key features of ubiquitous computing. 1. In ubicomp, there's factoring in the human element and placing the paradigm in a human, instead of just a computing, environment. 2. Here inexpensive processors are used so that memory and storage requirements are kept to a minimum. 3. Real-time attributes get captured in ubiquitous computing. 4. Totally c…
Layers in Ubiquitous Computing
- Ubiquitous computing can be looked at as consisting of several layers, each with its own roles and together they form a single system. Layer 1: This is the Task Management layer; it looks at user tasks, context and index. It also manages the complex dependencies that come with the territory. Layer 2: This is the Environment Management layer that keeps up with resources and t…
