What is meant by context in pervasive computing?

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 meant 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 are the three main types of context awareness?

In general, the contexts can be divided into core contexts and domain-specific contexts. While core contexts are common in most context-aware applications, domain specific contexts appear mainly in specific environments. In the following we are going to introduce the three core categories user, environment, and system.

What is context awareness example?

What is Context-Awareness? Generally, context-awareness is the ability of devices to sense their physical environment and adapt their behavior accordingly. A great example of context-awareness is how smartphones react to ambient light, adjusting their screen brightness for optimal readability.

What are the features of context-aware?

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).

What is context-awareness and perception?

In particular, we distinguish between a type of consciousness that relies on the firing of concept cells (contextual awareness) and the one that can be experienced even in the absence of MTL structures (perceptual awareness).

Why is context-aware computing important?

When we aim to create applications, devices, and systems that are easy to use, it is essential to understand the context of use. With context-aware computing, we now have the means of considering the situation of use not only in the design process, but in real time while the device is in use.

What are the features of context-aware computing?

Contextual or context-aware computing uses software and hardware to automatically collect and analyze data to guide responses. Context includes any information that’s relevant to a given entity, such as a person, a device or an application.

Why do we need context-aware computing?

What are context-aware applications?

An important class of mobile applications are context-aware applications: applications that change their behaviour according to the user’s present context-their location, who they are with, what the time of day is, and so on.
