Definitions and images of pervasive computing

Pervasive Computing Definition 1

The trend towards an information environment in which users have access to ICTs throughout the environment. This trend is particularly associated with the growth of wireless technologies that allow users to access online information and services remotely and synchronise data between different computers.

Pervasive Computing Definition 2

Inexpensive microprocessors embedded in everyday objects and environments. Characterised by being numerous, casually accesible, often invisible computing devices, frequently mobile or imbedded in the environment and connected to an increasingly ubiquitous network structure.framework.v2.nl/archive/archive/node/text/default.xslt/nodenr-156647

Pervasive Computing Definition 3

The use of a computing infrastructure that supports information appliances from which users can access a broad range of network-based services, including Internet-based e-commerce services. Pervasive computing thus provides users with the ability to access and take action on information conveniently.www.rapidspec.com/RapidSpec%20Site/PROJECT%20ASSISSTANT%20SECTION/DOC%20SERVICES%20SECTION/Project%20Literature/rsp-Technicalinfo_Term.htm

Ubiquitous computing definition 1

computers everywhere. Making many computers available throughout the physical environment, while making them effectively invisible to the user.mobileman.projects.supsi.ch/glossary.html

Ubiquitous computing definition 2

Ubiquitous computing (ubicomp, or sometimes ubiqcomp) integrates computation into the environment, rather than having computers which are distinct objects. Another term for ubiquitous computing is pervasive computing. Promoters of this idea hope that embedding computation into the environment would enable people to move around and interact with computers more naturally than they currently do. ...en.wikipedia.org/wiki/Ubiquitous_computing

similarities: interacting with the user, computers more natural.

Ambient Computing definition 1

The foundations of Ubiquitous Computing (also named Ambient Computing) have been defined by Marc Weiser in his paper titled "Some Computer Science Issues in Ubiquitous Computing" [24]. The goal of ambient computing is to provide services to users according to their current situation, and interactions have to be as implicit as possible. In his paper, Weiser noticed that using a computer today requires all the user's vigilance. The current mobile systems, used by mobile users, cannot address this type of constraints. In Ubiquitous Computing mobile systems have to be used more intuitively without explicit interactions. The design of system environments able to support such ubiquitous applications requires to address two main topics: the characterization of the different contexts in which users evolve (see paragraph 3.3.1), and the way information can be accessed by users in a mobile environment (see paragraph 3.3.3).

Ambient Computing definition 2

A wide variety of everyday objects consist of textile fibres (clothes, wallpapers, chairs). Their primary purpose is structural and aesthetic. Fibres can have added functions by the integration of computing power into the material that forms them. The purpose of this project is to integrate this new dimension of functionality into fibres, thus turn everyday objects into artefacts. The initial step is selection of materials and development of fibres. The basic unit of computation, the transistor will be implemented into these fibres. This is done using a novel technology for building transistors on an SOI structure in fibre form and releasing the structures to leave a free-standing flexible active device. Central processing units as well as sensors and memory could be integrated within one fibre by the interconnection of transistors. Computing fibres can be interwoven into everyday objects to create artefacts, which could be interconnected with each other or with their surroundings
