We have a number of student projects that look at novel applications and novel application platforms on mobile phones. As Michael Rohs from T-Labs is also teaching a course on mobile HCI we thought it would be a good opportunity to meet and discuss some application ideas.

I gave a talk in Michael’s lecture discussing the concept of user interfaces beyond the desktop, context as enabling technology, and future applications in mobile, wearable and ubiquitous computing. We had an interesting discussion – and in the end it always comes down to privacy and impact on society. I see this… Continue reading

In the final part of the summer school the students worked in groups to create new ideas for displays and their use. We had 5 groups working hard – all creating amazing results for such a short time. Sometimes I wonder how we could better utilize this design exercise as the results were really exciting.

On group looked into the concept of mobile and contextual displays on garments – the idea T-SHARE assesses potential applications, when having networked displays included in T-Shirts (see the group presentation for details). This moves an idea with have investigated over the last year to… Continue reading

Monday and Tuesday I organized together with Gernot A. Fink a PhD awayday for students in computer science of the Universities Bochum, Dortmund and Duisburg-Essen. With about 30 PhD students and some professors we went to Bommerholz, where the University of Dortmund has a small retreat.

The program included talks about career possibilities after the PhD including talks by:

This morning I was coming back from Munich* on the train I got a phone call from a journalist from Radio Essen (http://www.102.2radioessen.de/). As their studio is very close to the railways station in Essen I went there spontaneously before going back to University. 

We talked a little about web services for students to rate their profs (e.g. meinProf.de). The numbers of ratings most professors have received so far is extremely small (in comparison to the number of students we teach) and hence you get interesting effects that are far from representative or in many cases even meaningful. Last term I registered my course and we sent proactively a mail to all students who complete the course with the request to rate the lectures. This seems to be a good way to generate a positive selection 🙂 There are many of these services out – rating teachers, doctors, shops, etc. Thinking a little more about the whole concept of rating others one could image many interesting services – all of them creating a clear benefit (for someone) and a massive reduced privacy for others.  To make it more specific I offer you one idea: Rate your fellow students’ professonal capabilities and academic performance. Students have typically a very good insight into the real qualities of their peers (e.g. technical skills, social compatibility, creativity, mental resilience, ability to cope with workload, diligence, honesty etc.). Having this information combined with the official degree (and the transcript the university offers) a potential employer would get a really interesting picture… We discussed this with students last term an the reactions were quite diverse – as one can image.> Obviously such a service would create a lot of criticism (which lowers the cost of marketing) and one would have to carefully think in which countries it would be legal to run it. An interesting question would… Continue reading

While waiting for my conneting flight a saw a women posting a letter and filming this as she did it. She created some sort of proof. Thinking a little more and having further information in the background (e.g. a clock, the schedule display, people waiting) this this has some potential to replace registered mail for certain domains? This gives me an idea for a small weekend project…

The closing panel at Ubicomp dicussed the last 10 years of ubicomp and potential future direction (with regard to community and technology). On the panel were Gregory Abowd, Hide Tokuda, Lars Eric Holmquist, Eric Paulos, and Albrecht Schmidt. In the following I will just describe some of the points I raised in my short statement.  For me the first observation is that many ideas that were discussed at the first HUC99 (the first ubicomp conference started by Hans Gellsersen) – and were considered very speculative ideas have become common products and services by… Continue reading

While listening to BJ Fogg, and especially on the motivation pairs (in particular instant pleasure and gratification vs. instant pain) I was wondering how long it will take till we talk about and see implantable persuasion technologies. Take the example of obesity – here one could really image ways of creating an implant that provides motivation for a certain eating behavior… would this be ethical?
