>Currently we have an assignment in our
Pervasive Computing class that asks students to design and develop a system where actions are associated with artifacts. Technically students should develop a web based solution using RFID. Apropos RFID, … if you look for a good introduction on RFID read Roy Want’s IEEE Pervasive Magazin paper [1].
We use the hardware from
http://nabaztag.com/ (Ztamp:s and Mir:ror) as the focus is on the concept and application and not on the underlying technology. To ease development Florian and Ali have developed a little system that offers WebCallBacks (students can register a URL and that is called when a tag is read).
Linking by tagging of objects has been well explored, e.g. [2] and [3], and I think it is about time that this technologies will make an impact in the consumer market – the technology gets cheap enough now (and perhaps one of our students has a great idea).
Some years back (in the last millennium) a company tried to push linking of paper adverts and digital content with the CueCat (
http://en.wikipedia.org/wiki/CueCat) – I was impressed and inspired at that time but in my view it had two major weaknesses: (1) technically too early and (2) encoding of serial numbers instead of URLs. The RadioShack catalog and the Wired Magazine that included codes showed the potential – but it was too cumbersome as it was restricted to the PC …
We did some work on the topic, too around that time – at RFID reader integrated in a glove – which resulted in a Poster at ISWC [4] and a patent [5].

Petra is teaching at the primary school in Satteldorf. As there is no University close by we decided to have a university afternoon at school. The idea behind this (in German Kinderuniversität) is to get young children excited for scientific topics and show that research is fun. The lecture should make them curious and motivate them to ask fundamental questions.
My lecture was on principles and technologies for communication (in German) and we looked fundamentally at what information is, how it relates to probabilities, how to encode information, and what devices people used and use for communication. For me this was a very exciting experience and also showed that we (as a discipline Computer Science) should probably look more into didactic and how to communicate fundamentals of our subject in school. So far many students associated computer science with using PowerPoint 
but there are interesting starting points, e.g. a German book on algorithms for school children [1].
