First Ubiquitous IT Europe Forum

The first European conference dedicated to uHealth is coming up in Bonn, Germany. Among organizers are University of Bonn, Fraunhofer IAIS, the Institute for Intelligent Analysis and Information Systems, u-Korea Forum and Korea u-City Association. Find more information on the conference website:
The Ubiquitous IT Europe Forum organizes, in conjunction with the University of Bonn and Aving Global News Network, a series of conferences on the topic of ubiquitous computing.
The first event in this series takes place in Bonn, Germany between March 10th and 12th, 2008. The main objective is to bring together the Asian and European communities that actively work on ubiquitous technologies to foster the exchange of experiences and encourage future global collaborations. The conference will be held at the World Congress Center in Bonn, which is the former federal government Plenary Chamber.
Attendance is free, and the conference program has 16 sessions addressing uCity Technologies, European Projects, uApplications. In addition Keynotes and Panel Discussions are scheduled.

Ubiquitous? pervasive? spime? - what's in a word?

What's the difference between 'ubiquitous computing' and 'pervasive computing'? Is there a difference? Does it matter?

I was reading an article on 'Effects of Pervasive Computing on Sustainable Development' ( >>> ) that began with the words 'Since pervasive computing is expected to become ubiquitous in the coming years ...' It set me off thinking about previous discussions of the differences between the terms, so I did a bit of Googling and Wikipedia'ing and came up with:

"Pervasive Computing" is: Shorthand for the strongly emerging trend toward:
* Numerous, casually accessible, often invisible computing devices
* Frequently mobile or imbedded in the environment
* Connected to an increasingly ubiquitous network structure
The aim is for easier computing, more available everywhere it's needed
(NIST Pervasive Computing Conference 2000 - http://www.nist.gov/pc2000/)

"Ubiquitous computing is a post-desktop model of human-computer interaction in which information processing has been thoroughly integrated into everyday objects and activities ... someone "using" ubiquitous computing engages many computational devices and systems simultaneously, in the course of ordinary activities, and may not necessarily even be aware that they are doing so.
(Wikipedia entry for 'Pervasive Computing' - http://en.wikipedia.org/wiki/Pervasive_Computing)

Dictionary definitions are not much more help:
ubiquitous - adj : being present everywhere at once;
pervasive - adj : spread throughout;

And finally - the IEEE Pervasive Computing Journal (www.computer.org/portal/site/pervasive//) describes itself as 'A catalyst for advancing research and practice in mobile and ubiquitous computing' (sic).

So, they seem to be somewhat interchangeable.

And 'spime'? - that's a word made up by writer Bruce Sterling for a "currently-theoretical object that can be tracked through space and time throughout the lifetime of the object ... spimes as coming through the convergence of six emerging technologies, related to both the manufacturing process for consumer goods, and through identification and location technologies.

These six facets of spimes are:
1. Small, inexpensive means of remotely and uniquely identifying objects over short ranges; in other words, radio-frequency identification.
2. A mechanism to precisely locate something on Earth, such as a global-positioning system.
3. A way to mine large amounts of data for things that match some given criteria, like internet search engines.
4. Tools to virtually construct nearly any kind of object; computer-aided design.
5. Ways to rapidly prototype virtual objects into real ones. Sophisticated, automated fabrication of a specification for an object, through “three-dimensional printers.”
6. “Cradle-to-cradle” life-spans for objects. Cheap, effective recycling.

Ubiquitous (or pervasive?) computing could be a way for spimes to be developed and used - it would be interesting to think about potential health applications.
