"reacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers attached onto physical objects, as well as for multi-touch finger tracking. It was mainly designed as a toolkit for the rapid development of table-based tangible user interfaces (TUI) and multi-touch interactive surfaces. "

"Over the last week in my new first-year undergraduate course, Media Fluency for the Digital Age, my students have been wrestling with a very counterintuitive digital media assignment, and I think it's worth exploring why these members of the "born digital" generation found this assignment so difficult — and so rewarding.
Here's the challenge they were given:
Finding information that's not online. Find an article (research journal article, analytic newspaper article, serious magazine article, or scholarly book chapter) that is on the topic of the Internet or new media, but not available (at least, not to you) on the Internet, and acquire a digital copy of that article. "
It’s the same list that emerges when I talk about computational thinking, or Fourth R principles, or thinking like the web. Here’s an edited version of the list we put up on the easel that day:
Be the authoritative source for your own data
Pass by reference not by value
Know the difference between structured and unstructured data
Create and adopt disciplined naming conventions
Push your data to the widest appropriate scope
Participate in pub/sub networks as both a publisher and a subscriber
Reuse components and services
"Human-Centered Informatics (HCI) is the intersection of the cultural, the social, the cognitive, and the aesthetic with computing and information technology. It encompasses a huge range of issues, theories, technologies, designs, tools, environments and human experiences in knowledge work, recreation and leisure activity, teaching and learning, and the potpourri of everyday life. The series will publish state-of-the-art syntheses, case studies, and tutorials in key areas. It will share the focus of leading international conferences in HCI."
You begin in the middle of the spiral and gradually work your way to the outer point. Each of the ‘spokes’ represents an action of reading or thinking something. Each time the spoke cuts across the spiral it is at a different time (T1, T2, T3, …Tn). The point is that each spoke is not the ‘same’ thing each time it cuts across the spiral. Ideas develop as you read and think different things in between. So the series becomes something like Idea 1.0, Idea 1.1, Idea 1.2, …Idea 1.n and you get an appreciation of the way what you read or thought in the beginning develops over time. When writing up the research you write up the spokes.
This is great for a process involving small sets of starting information with only ‘interference’ or ‘reinforcing’ effects between the original set of information creating change. This is not how scholarship actually happens, however. Scholarship is essentially a process of innovation involving ‘interference’, ‘reinforcement’ and also ‘cascade’ and ‘originary’ effects. A ‘cascade’ effect being that joyous moment where the ‘red thread’ of one’s work is apparent. An ‘originary’ effect being that moment where the differential repetition of ideas (what Gabriel Tarde called ‘imitation’) leads to development of a new idea (or what Tarde called ‘innovation’).
