Having used the Sony PRS-505 now for a few weeks (mainly to read dissertations and project reports) I have quickly gotten used to carrying less weight. The user interface requires some learning – as the screen is pretty slow pressing a button does not give immediate feedback and that feels strange – more than expected. I wonder if there are studies on traditional interacton with electronic paper? Another issue: it seems to depend on the crew whether or not it is OK to read from an eBook during the entire flight (including take-off and landing)…

While reading a thesis I… Continue reading

Going to Christmas market is in Germany a tradition – and obviously our group went, too 😉It is interesting that most of us had time for this “appointment” with only two days notice – usually it takes us weeks to find a date for a meeting and so far we did not find a date for a strategy meeting in the near future. Perhaps offering Glühwein (that is what you drink at Christmas markets) would help…The quality of photos taken with a mobile phone is in difficult context (e.g. night, lights around) still not satisfactory (even with 5MP, downscaling, and image enhancing).

Lucia Terrenghi and Thomas Lang from Vodafone R&D in Munich visited our lab. We talked at lot about the future role of mobile devices and in particular how they may change personal computing in the near future. 

After lunch they gave a talk for our students describing Vodafone research and their particular research interests. Using a nice visualization of train lines they showed the research themes and introduced some of their research foci. One area of interest is electronic paper, resulting future devices and potential applications and services. In the discussion I briefly mentioned that I had a look… Continue reading

Christian Kray and I were colleagues in Lancaster for a very short time – he just joined the university when I left for Munich. After his post-doc in Lancaster he moved to a position in Newcastle.

His work at the cross roads of mobile interaction and public displays is very exciting. In particular he investigates interesting concepts related to visual codes – some aspects to these ideas are discussed in “Swiss Army Knife meets Camera Phone” [1]. His new prototypes are really cool and I look forward to see/read more about them.

We realized that there are many… Continue reading

Paul presented after lunch our full paper on a development approach and environment for mobile applications that supports underlying user models [1]. In the paper he shows how you can create applications while programming by example where the development environment automatically adds a KLM model. In this way the developer becomes automatically aware of estimated usage times for the application. The paper is work that builds on our paper on KLM for physical mobile interaction which was presented last year at CHI [2]. The underlying technology is the embedded interaction toolkit [3] – have a look – perhaps it makes… Continue reading

Paul Holleis presented at TEI’08 the results of the research he did during his internship at Nokia Research [1]. Over the summer Paul spent 3 month with Jonna Häkkila’s group in Helsinki, where he worked on two projects: combing touch and key-presses and wearable controls.

Technically both projects used capacitative sensing to recognize touch. In his paper “Studying Applications for Touch-Enabled Mobile Phone Keypads” [1] they added to common mobile phone buttons touch sensing so that multiple levels of interaction can be measured, such as approaching, touching and pressing. The paper additionally discusses new interaction possibility that arise… Continue reading

Arriving in Zurich I was quite surprised by the masses of people in the train station. We picked the weekend of the Street Parade for our visit 😉 makes you really think about your own age…

In the railway station they had digital giveaways – you just had to switch your Bluetooth on.

It seems that recently I come across many people that speak on the phone while they do their work. In Toronto on the bus to the airport the driver spoke on the phone (telling someone how to find and edit a file in Windows) while driving. Here in Bonn I saw it in shops and on the ferry – it felt really awkward to interrupt people in their phone conversation just to pay my ticket or bread.

At the moment most people speak while holding a handset – but given they use BT-headsets one could image new working practice 😉… Continue reading
