Paul presented a paper on mobile phone interaction at TEI’08

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 from this.

Where are my things – Would Smart-its friends help in a real world scenario?

At social events of conferences interesting things happen. One issue with a borrowed key reminded me of a paper that colleagues in the smart-its project wrote several years ago – smart-its friends [1]. The central idea was to have means to connect objects (make them friends) by a gesture interaction, which is detected by comparing acceleration values. Technically it is feasible and highly interesting, but I wonder about the real world applicability – but the missing key may be evidence for it…

Keynote by Prof. Ishii at TEI’08

In the evening Prof. Hiroshi Ishii from the MIT Medialab presented a fascinating keynote at TEI’08. He gave an exciting overview of his work in tangible user interfaces, starting from tangible bits [1]. Right after the demos it was impressive to see how much impact he had on this area of research. He has a paper that accompanies the keynote in the proceedings, that will be soon available in the ACM DL.

On central piece of advice on research was to work on visions rather than on applications. He argues visions may last 100 years and applications are likely to be gone after 10. However he made the interesting connection between the two. You need to have applications to convey and communicate the visions, but you need to have the vision to create the applications. He had a great a slide (which indicates that we will go to heaven) to motivate to do something to be remembered in 200 years – not sure if this is my plan.

He criticized interdisciplinary research as we do it at the moment. In his few the most efficient way for interdisciplinary way is to make a single person knowledgeable in several fields. This raises issues in education and in the discussion afterwards there was the question whether this is feasible beyond the MIT or not.

Talks, Demos and Poster at TEI’08

The first day of the conference went well – thanks to many helping hands. The time we had for the demos seemed really long in the program but was too short to engage with every exhibit (for next year we should make sure to allocate even more time).

People made really last minutes efforts to make their demos work. We even went to Conrad electronics to get some pieces (which burned before in setting up the demos). Demos are in my eyes an extremely efficient means for communicating between scientists and sharing ideas.

New working group on tangible interaction

This morning a new working group on tangible interaction in mixed realities (in German Be-greifbare Interaktion in Gemischten Wirklichkeiten) was established as part of the German Computer Science Society (GI). About 30 people from all over Germany gathered at B-IT in a pre-conference event to TEI’08. The group was interdisciplinary, including computer science, design, psychology, and pedagogic. The diversity of research projects as well as teaching programs in Germany in impressive.

Visit to the Arithmeum in Bonn

For people who already arrive on Sunday, the day before the conference, we organised some museum visits: Arithmeum, Haus der Geschichte, Deutsches Museum, and Art Gallery. I only had time to see the Arithmeum (http://www.arithmeum.uni-bonn.de/) which was pretty impressive. Hiroshi Ishii (the keynote speaker of the conference) and Brygg Ullmer (last years conference co-chair) joined us, too.

It was unexpected how close the displayed artefacts are to our current research on tangible interaction. We had a very good guided tour by Nina Mertens, who gave us an interesting overview from counting tokens to calculation machines. Some of the exhibit we could even try out our selves.

I found the aspect of aesthetics in some of the calculation aids and machines quite fascinating. Especially the fact that some were so precious that they were not really used for calculating but more for showing off is a concept that is amazing. Similarly interesting was one artefact that was mainly built as a proof that calculation can be automated.

Press-releases for TEI’08 – explaining the idea

We have two press releases to announce TEI’08 – the second international conference on tangible and embedded interaction (in German only).

The first one is a general announcement with the invitation to the press conference: Internationale Konferenz zu neuen Möglichkeiten der Mensch-Maschine-Interaktion

The second one is explaining – in non-scientific terms – the idea of tangible and embedded interaction: Der Wetterfrosch im Regenschirm
