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).
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” . 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 . 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 . The underlying technology is the embedded interaction toolkit  – 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 . 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”  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
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
