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…
- Implanted activity recognition and interaction (put the sensing and actuation into the body solves a lot of the problems … obviously it creates many new ones, too)
- Implantable persuasion and amplifying bodily experiences. Here I gave the example that we would be able to create a device to motivate you do sports by making your back hurt. I used this to emphasise that ethics will play a large role in the future…
- Prediction technologies (e.g. the weather forecast as an inspiration, forecasting traffic conditions, parking situation, restaurant business, costs, …) we will create systems that allo us to look up predictions (cost, quality of the experience, stress, time needed, etc.) for future activities (e.g. when choosing a restaurants, booking a travel, deciding on dating a person, making a business deal, accepting a position, …)
- And finally I suggested that we will have fun with papers on privacy published now when reading them in 20 years 🙂 because our perception of this topic will change massively.
Over the last days there were a number of interesting papers presented and so it is not easy to pick a selection… Here is my random paper selection from Ubicomp 2008 that link to our work (the conference papers link into the ubicomp 2008 proceedings in the ACM DL, our references are below):
Don Patterson presented a survey on using IM. One of the finding surprised me: people seem to ignore „busy“ settings. In some work we did in 2000 on mobile availability and sharing context users indicated that they would respect this or at least explain when interrupt someone who is busy [1,2] – perhaps it is a cultural difference or people have changed. It may be interesting to run a similar study in Germany.

In the doctoral colloquium at Ubicomp 2008 we saw an interesting mix of topics including work on context-awareness, interaction in smart space, home infrastructures and urban environments. Overall there is again the observation that in ubicomp topics are very broad (at least in the beginning) and that it is not easy to narrow it down.
There are many more papers to read if you are interested in tactile communication and output, here are two suggestions  and .

PS: Just one remark on the term „framework“ (a favorite word to use in dissertation and paper titles) – it is not a clear term and expectations are very different, hence it make sense to think twice before using it 😉
We got a new USB GPS tracker(from Mobile Action, GT100) and had to try it out on the trip to Korea. It worked very well compared to the other devices we had so far. It got the bus trip in Düsseldorf airport right and the entire flight from Amsterdam to Seoul. Tracking worked well in the taxi from the Airport to the hotel. While walking in downtown Seoul it still performed OK (given the urban canyons) with some outliers.
On the way into town we got a really good price for the taxi (just make a mental note never to negotiate something with Florian and Alireza at the same time 😉 It seems taxi driving is sort of boring – he too watched television while driving (like the taxi driver some weeks ago in Amsterdam). I think we should seriously think more about entertainment for micro breaks because I still think it is for a good reason not allowed to watch TV while driving.
Seoul is an amazing place. There are many digital signs and electronic adverts. Walking back to the hotel I saw a large digital display on a rooftop (would guess about 10 meters by 6 meters). If working it is probably nice. But now it is mal functioning and the experience walking down the road is worsened as one inevitably looks at it. I wonder if in 10 years we will be used to broken large screen displays…
I have learned about Chumby an interesting platform that is designed to replace devices on your bedside table. Looking forward to get one or some when I fly next time to the US.
For a design competion at the appliance design conference I did a design concept for a networked alarm clock  assuming that networked device will be soon cheaply available. Maybe we should look at the paper again and think about how to push such ideas forward as the devices are on the market…
