ubiquitous computing

Computers everywhere. Making many computers available throughout the physical environment, while making them effectively invisible to the user. Ubiquitous computing is held by some to be the Third Wave of computing. The First Wave was many people per computer, the Second Wave was one person per computer. The Third Wave will be many computers per person. Three key technical issues are: power consumption, user interface, and wireless connectivity.

The idea of ubiquitous computing as invisible computation was first articulated by Mark Weiser in 1988 at the Computer Science Lab at Xerox PARC.

pervasive computing

The use of computing devices in everyday life, not only at a desk. Also called "ubiquitous computing," it includes laptops, tablets, smartphones, wearable devices, appliances and sensors. Pervasive computing implies that people are not necessarily aware of every information-gathering unit surrounding them. See pervasive workplace and Internet of Things.

With the ongoing development of cheaper miniature and smart sensors; abundant fast and ubiquitous computing devices; wireless and mobile communication networks; and autonomous and intelligent software agents, the Sensor Web is rapidly emerging as a powerful technological framework for geospatial data collection, fusion and distribution.
Smart-world technologies are an extension of Weiser's vision for ubiquitous computing. Creating sensitive, associative, adaptive environments frees a person from having to gain specialized knowledge of computation to reap the computation benefits.
By sensing and computing the learners' surrounding environment, ubiquitous computing technologies and a software application are combined in order to recommend peer helpers who may be more likely to fit to the learners' context and tasks.
The architect of ubiquitous computing imagined just the opposite: a crescendo away from our machines and back into the real world.
It is clear that it will take at least a few decades before ubiquitous computing environments will be available, so this field is not and will not be the driving force behind wireless sensor network development.
Ubiquitous computing supports activities in environments that are physically distributed and brought closer to the customers and operations.
In addition, the perspective of ubiquitous computing and ambient intelligence allows for a wider perspective on group formation, broadening the range of addressed features to include learner context information.
As the miniaturization of computing devices and the convergence of their functions make "ubiquitous computing" more likely, the need to understand how we react in digital environments becomes more important.
Does the advantage of "ubiquitous computing"--tech-speak for being connected to a computer and network no matter where you go--give you a better shot at searching and finding the information you need?
As I write this, the thought of such ubiquitous computing and infinite knowledge of me becomes terrifying.
[P]art two discusses students in a distributed learning community--this time based on emerging technologies of augmented reality and ubiquitous computing. The article also will describe the next steps for our society to realize this vision of educational improvement."
