acatech workshop: object in context

admin Schreibe einen Kommentar

It was interesting to see that smart objects / smart object services, context, NFC, and RFID become very mainstream. It seems that nearly everyone buys into these ideas now.

Dr. Mohsen Darianian (from Nokia Research, same building as Paul Holleis is at the moment) showed an NFC-advert video which reminded me on the results of an exercise we did on concept videos within an HCI-class at the University of Munich 🙂

Overall it seems that acceptance and business models are of great interest and that to create them a lot of technical insight is required. The issues related to user interfaces, interaction, experience become central factors for the success of products and services.

One discussion was on the motivation for people to contribute (e.g. user generated content, write open source code, answer questions in forums, blogs). Understanding this seem crucial to the prediction whether or not a application is going to fly or not.

Besides contributing for a certain currency (e.g. fame, status, money, access to information) it seems that altruism may be an interesting factor for motivating potential users. Even if it is a low percentage within our species the absolute number on a world wide scale could be still enough to drive a certain application/service. There is interesting research on altruism in the animal world (or at the researchers page http://email.eva.mpg.de/~warneken/ ) maybe we should look more into this and re-think some basic assumptions on business models?

Our break out group was in the rooms of the Institute of Electronic Business e.V (http://www.ieb.net/). It is a very pleasant environment and their link to the art school reflects very positive on the atmosphere and projects. The hand drawn semacodes were really impressive.

Panel on Users as Producers at Schloss Birlinghoven

In the castle on campus Ute SchĂŒtz and Michael Krapp from IAIS and SCAI organize a public panel discussion on citizen journalism and Web 2.0 trends. The discussion looked at the topic from several angles including technology, content, and communication. I had the honour to be on the panel with Wolfgang Back, Frank Patalong, Moritz „mo.“ Sauer and Thomas Tikwinski.

On issue was how much blogs are (mis)used to transport information or to do advertising. The web seems to be to many people a very believable medium. This reminded me of an article I read some time ago on story-telling o n the web (Miller, J. 2005. Storytelling evolves on the web: case study: EXOCOG and the future of storytelling. interactions 12, 1 (Jan. 2005), 30-47. DOI= http://doi.acm.org/10.1145/1041280.1041281). I think something along this lines would an interesting project with students.

The questions what is going to change in the near future on the WWW brought many trend statements out, but for me it is amazing that most of the infrastructure and technology we need to make this happen is out there. One comment which I think is really true is that it is more an more about content and communication again. As Thomas said before the panel – most of the great things that are called Web 2.0 have been in the original proposal for the WWW (e.g. annotations by everyone or users as editors) – but now technology is finally there that people can use it.

Panel on Sensor Networks – Applications are the Key

admin Schreibe einen Kommentar

Debora Estrin made an interesting statement. The “early challenges” (the thousands or millions of randomly scattered sensor notes) do not have much applicability outside the battlefield. The new challenges are heterogeneity (specific sensors with specific capabilities) and interactivity (basically sense-making is a process where humans are involved). She made the point that the logical consequence is that dealing with data is the essential issue and statistics have an increasing role. Furthermore these new research directions make a stromg call for application driven research. With these very insightful comments she criticised a lot of the current work in sensor networks. Especially the observation that there is no such thing as a „general sensor“ – it points out that concrete applications are required to make meaningful contributions, even to basic research in sensor networks research.

PerTec Workshop in NY, Ripping off the Antenna

admin Schreibe einen Kommentar

At PerCom 2007 (www.percom.org) Florian Michahelles (Auto-ID labs, ETH Zurich), Frédéric Thiesse (University of St. Gallen), John R. Williams (MIT Cambridge) and I are running the the PerTec workshop (www.autoidlabs.org/events/pertec2007). There is quite some interest in the topic and the range of topics is from technical to user interface and security.

In contrast to the workshop 1 year ago at Pervasive 2006 it seems that item level RFID-tagging is undisputed and that the only discussion point is when it is coming – in 6 month or 10 years. There is also still some discussion about what types of products are the first ones that are tagged – is it pharmaceuticals or cloth?

There was an interesting contribution by Paul Moskowitz from IBM, the clipped tag. It is a tag where you can physically rip off some part the antenna to reduce the read range from several meters to centimetres (see the pictures). It is really interesting that people can do a very clear and visible action to change the characteristics of a tag. The only questions that remains for me – will people trust that this really rips of the antenna? Probably yes


The topics we discussed included security, privacy, location and RFID, end user issues, and connection of sensors to RFID, we hope to write it up in an overview article.

In the break out groups one discussion centered on the question what would we need to enable end-users to create novel applications using RFID? Further results of the discussion will be available on the workshop webpage soon.

The overall theme that emerged again and again is impact of real world constraints in RFID systems. Questions like: Can you achieve anonymity with a certain protocol? Can not be answered without knowing how it is used in the real world. Especially having recently learned a lot about data-mining (being at Fraunhofer IAIS) for me the questions of exploiting data collected in RFID systems looks really challenging.

Broadcasting your Heart Beat

admin Schreibe einen Kommentar



This morning the first 3 students completed the exercise part of our lab class. For the first team the basics are done and we start with the exciting part 😉

We have different sensors that can be connected via Bluetooth to the phone (e.g. heart rate, pulse oximeter, GPS) and the task for the project is to invent a new application that makes use of sensors and creates a new user experience.

In the brainstorming session some were tearing out their hair – but it was rewarding. Some of the ideas that came out are really novel – and perhaps a bit to crazy to implement them. One example of such an idea is to create a web radio station that broadcasts the live heart beat of celebrities as an audio stream (not sure if this is the right way to fame). Other ideas centered on support for sport, exercise and mobile health.

Alexander De Luca (a former colleague from LMU Munich) was spending the last few days with us here. He helped greatly to write some code to get the Alivetec-ECG data parsed.

Affectionate Computing

Thecla Schiphorst introduced us in her talk “PillowTalk: Can We Afford Intimacy? to the concept of Affectionate-Computing.
The central question is really how can we create intimacy in communication an interaction with and through technology? The prototype showed networked soft objects, that include sensors that recognize tactile qualities and gesture interaction. There are more details in her paper published at TEI’07.
