Ubiquitous computing (or "ubicomp") is a concept in software engineering, hardware engineering and computer science where computing is made to appear seamlessly anytime and everywhere. In contrast to desktop computing , ubiquitous computing implies use on any device, in any location, and in any format.
Context awareness originated as a term from ubiquitous computing or as so-called pervasive computing which sought to deal with linking changes in the environment with computer systems, which are otherwise static. The term has also been applied to business theory in relation to contextual application design and business process management issues ...
However, pervasive informatics places a greater emphasis on the ICT-enhanced socio-technical pervasive spaces, as opposed to the technology driven direction of pervasive computing. This distinction between fields is analogous to that of informatics and computing , where Informatics focuses on the study of information, while the primary concern ...
The concept emerged from ubiquitous computing research at Xerox PARC and elsewhere in the early 1990s. [citation needed] The term 'context-aware' was first used by Schilit and Theimer in their 1994 paper Disseminating Active Map Information to Mobile Hosts where they describe a model of computing in which users interact with many different mobile and stationary computers and classify a context ...
The concept of ambient intelligence builds upon pervasive computing, ubiquitous computing, profiling, context awareness, and human-centered computer interaction design. It is characterized by systems and technologies that are: [7] [6] Embedded: Networked devices are integrated into their environment.
Pervasive may refer to: Pervasive Computing, human computer interaction paradigm; Pervasive Informatics, study of how information affects human interactions; Pervasive Software, software company in the United States Pervasive PSQL, software developed by the company; Pervasive games, games that blend with the physical world
Task computing is a computation meant to fill the gap between tasks (what the user wants to be done) and services (functionalities that are available to the user). Task computing seeks to redefine how users interact with and use computing environments. It is built on pervasive computing.
Pervasive Software was a company that developed software including database management systems and extract, transform and load tools. Pervasive Data Integrator and Pervasive Data Profiler are integration products, and the Pervasive PSQL relational database management system is its primary data storage product.
