On Wednesday and Thursday Enrico visited our group in Essen. He gave a part of my lecture on user interface engineering talking about mobile interaction with the real world. He include interesting examples, such as QR-code/NFC/RFID use in Asia, SixthSense project (camera projection system to wear around the neck) and handheld mobile projections. Enrico also explained some of the multi-tag work he does at Lancaster University .
In the lecture we talked briefly about future devices and interfaces. I mentioned one example: projection in the large – on building scale. The 3D visualization overplayed on buildings seem impressive – at… Continue reading
The 8th International Conference on Mobile and Ubiquitous Multimedia (MUM 2009) was held in Cambridge, UK. The conference is fairly specific and had an acceptance rate of about 33% – have a look at the table of content for an overview. Florian Michahelles presented our paper on a design space for ubiquitous product recommendation systems . Our work contributes a comprehensive design space that outlines design options for product recommendation systems using mobile and ubiquitous technologies. We think that over the next years mobile recommendation systems have the potential to change the way we shop in the real world.… Continue reading
Finland is one country in Europe were it seems pretty hard to get to in the morning from Germany or Austria. If you have a meeting before 11 am you have to fly the day before.
I was invited to Helsinki to be opponent (together with Kaisa Väänänen-Vainio-Mattila) for the PhD defense of Elina Vartiainen at Helsinki University of Technology. The first time I came across work she was involved in was at CHI 2006 in Montreal. She worked with Virpi Roto on the Minimap web browser . Last year in a doctoral colloquium in Finland we first discussed some… Continue reading
Florian Alt presented our work on pervasive advertising, in particular on creating dynamic user profiles in the real world . This research was carried out together with colleagues in marketing and software systems and implemented in one of our course. We are proud that it got named best paper at AmI 2009! Another paper to look at in this context was presented by Jörg Müller; it looked at pervasive advertisement utilizing screens on public phone boxes. The study is amazing in size (20 displays all over Münster, 17 participating shops) and duration (1 year, 24/7) . Even though the results… Continue reading
In the opening keynote of AMI 2009 Frits Grotenhuis (who stepped in for Emil Aarts) looked back at the last 10 years ambient intelligence. In his talk he showed a number of examples of devices that Philips created in this time, including iCat, the Entertaible, Ambilight, and medical devices. He discussed briefly the forces in such developments between market-pull and technology-push and it became evident that many products in this domain are more technology push than market-pull.
The central role of ICT becomes very visible when it does not work. Sometimes for the good as I was late arriving at Düsseldorf airport but the Airberlin check-in system was down for a few minutes – just enough that I was still in time
In the evening I met Prof. Lorenz Hilty, who gave a talk in the afternoon at ETH Zurich. I missed the talk but after the interesting and though provoking dinner conversation I decided I should finally really read his book  – perhaps over Christmas. Meeting with Friedemann Mattern and Hans Gellersen was very… Continue reading
In the refurbished railway station (not yet finished) there is an interesting new pixel display in one main underpass. One wall is covered with a display. It is about 10 pixel (probably about 4 meters) high and several hundred pixels long (have not counted/measured them). It changes colors and shows writing (so far not really exciting).
How cool would it be if there is a freely accessible programmable web-service to control these pixel? I would guess people could create all sorts of interesting content… Perhaps people would start to bargain to get their 5 minutes of virtual graffiti shown…
Together with Antonio’s group we looked at new forms of interaction beyond the desktop. The journal paper Tangible, Embedded, and Reality-Based Interaction  gives overview and examples of recent trends in human computer interaction and is a good starting point to learn about these topics.
Abstract: Tangible, embedded, and reality-based interaction are among novel concepts of interaction design that will change our usage of computers and be part of our daily life in coming years. In this article, we present an overview of the research area of tangible, embedded, and reality-based interaction as an area of media informatics. Potentials and… Continue reading
Base on work we did together with DoCoMo Eurolabs in Munich we have published the article “Perci: Pervasive Service Interaction with the Internet of Things” in the IEEE Internet Computing special issue on the Internet of Things edited by Frédéric Thiesse and Florian Michahelles.
The paper discusses the linking of digital resources to the real world. We investigated how to augment everyday objects with RFID and Near Field Communication (NFC) tags to enable simpler ways for users to interact with service. We aim at creating a digital identities of real world objects and by this integrating them into… Continue reading
In my lecture on user interface engineering I start out with a short history of human computer interaction. I like to discuss ideas and inventions in the context of the people who did it, besides others I take about Vannevar Bush and his vision of information processing , Ivan Sutherland’s sketchpad , Doug Engelbart’s CSCW demo (including the mouse) , and Alan Kay’s vision of the Dynabook .
One aspect of looking at the history is to better understand the future of interaction with computers. One typical question I ask in class is “what is the ultimate user interface” and… Continue reading
