bi-t Student demo lab results at Fraunhofer IAIS

This morning we presented selected demos of the lab on location and context awareness to people at the Fraunhofer IAIS. Besides the fact that our main infrastructure component (the Ubisense indoor system) did not work the demos went well. It was very strange – the infrastructure worked for the last 6 weeks (including several reboots) and this morning after rebooting the server it did not find the sensors anymore for several hours.

The majority of demos were based on the second assignment which was to create a novel application that makes use of an indoor location system. The applications implemented by the students included a heat-map (showing where a room is mainly used), co-location depended displays (enabling minimal setup effort and admin effort), museum information system (time and location depend display of different levels of information), and a security system (allowing a functionality only inside a perimeter dynamically defined by tags). Overall it was very interesting what the students created in 4 weeks of hard work.

We also briefly showed the location post its which were based on GPS and were done for the first group assignment, the CardioViz prototype (from the lab in the winter term), and the Web annotation tool that is now nearly ready.

Even though there were some difficulties in running some of the demos I am still convinced in a research environment we need to show live demos and not just ppt-slide-ware 😉 We probably have to demo more to get more professional with non-working components.

Interaction Ivrea

Pascal Bihler send me today a link to an interesting teaching/research project at Ivrea (http://courses.interaction-ivrea.it/strangely/). The assignment is to think how a common artefact can be enhanced with digital technology. The results of the exercise are quite impressive. It seems that Interaction Ivrea is now somehow integrated into the Domus Academy in Milan.

When I was at Ivrea in November 2003 for the Jamboree of the disappearing computer initiative it was amazing to see the level of creativity – from the Ivrea design institute as well as from the various European projects in the disappearing computer program.

There at Ivrea I also met a really amazing person who has greatly influenced interaction design in the last 20 year: Gillian Crampton Smith. She was the founding director of the institute in Ivrea and has moved on to Venice (IUAV).

Ubisense system at IAIS used in the lab

During our lab on context- and location-aware systems we have currently one task to create a novel application using the Ubisense indoor location system. We have set up a little server in C# that reads out the tag-ids and the current x,y,z coordinates and multi-casts it via UDP to several clients.

The students have to create an application that reads the tags and their locations from UDP and make use of it. One first interesting result was a heat-map, that would allow to map out the usage of the room. By the end of term we hope to have a nice set of applications.

For many students it was the first time at the Fraunhofer lab and hence they found interesting things to play with. E.g. Diana explored the PointScreen , a system developed in the division Virtual Environments at Fraunhofer IAIS. Further reading on the point screen:

Audio Tapes Soon be History, Printed Paper Next?

News papers in the UK have reported that sales for audio tapes at Currys were down from 83 million in 1989 to 0.1 million in 2006 and hence Currys is going to stop stocking them. We recently discussed how expensive talking toys (in particular dolls) were just twenty years ago. The were based on mini records or endless tapes. By now storage chips are so cheap that a good birthday card can sing you happy birthday.

How long will it take before electronic paper will replace printed paper in the large? At least it is close enough to seriously think about applications and business models that arise.

Lecture at CDTM in Munich

The CDTM is a joint elite study program from LMU Munich and TU Munich (http://www.cdtm.de/). It offers a set of complementary course for students from different backgrounds including math, business studies, engineering, computer science and media informatics. In their course on multimodal HCI I gave today an introductory lecture on the motivation for and the basics of user interface engineering.

In the seminar room was a real typewrite – in fact a travel type write. It was a real good prop to discuss micro- and macro-efficiency.

One question about the sustainability of a competitive advantage based on user interfaces made me really think. As the user interface is visible it is really hard to protect the competitive advantage and IPR are difficult on this topic. Desktop GUIs are a good example how quickly ideas propagate between competing systems. The only real option to maintain a competitive advantage is to continuously innovate – keeping the status quo means falling behind. The fact that one can not keep new user interface concepts secret (if one includes them in a product) is one of the most exciting aspects of user interfaces research – it is fast moving because everyone shows off their results!

User tests and final presentations of the lab course



This week the final presentations of the lab course were due. It was really interesting to see what motivated students can achieve in just 4 weeks! The projects explored the idea of contextual ECG and students implemented the data acquisition, transmission over the network, and visualisation. The user studies showed that there is quite some potential in the idea (even though there is also still some way to go before the system is perfect 😉 We plan to publish a paper on the results of the course.

Business in a Nutshell, Thoughts on Patents

Thomas Doppelberger and Andreas Aepfelbacher from Fraunhofer Venture Group (http://www.venturecommunity.de/) came to our lab course to teach us how to get from a technical idea to a successful business. They talked us through the essentials of a business plan, discussed common mistakes and gave us an insight how companies are evaluated and furthermore encouraged our “entrepreneurial thinking”.

After such a day and the interesting discussions with them and the students one wonders why we are not trying more often to look into the option of starting a company. Obviously not every start-up is the next youtube or second life – but without trying ideas out, there is not way in telling if the work or not.

Over lunch we talked very briefly about issues on patents and licensing. Even though the value of patents for companies is fairly comprehensible many questions remain open in publicly funded research institutions, – especially with regard to computer science. Thinking a little more about the figures they presented in the morning I wonder how the balance (over all publicly funded research in universities and non-profit institutions) between investments in securing rights (basically making patents and holding them) and income (e.g. licensing) is. Are there any figures available? Within the whole Fraunhofer Gesellschaft it is impressive to see the contribution of one development such as MP3 to such an equation.

Broadcasting your Heart Beat



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.

Lab started: Developing Interactive Mobile Applications

Our Lab course on „Developing Interactive Mobile Applications“ started today with 11 students (the limit was 8 – but 3 more is OK as we got some additional phones from Nokia).

Shortly after lunch everyone had there first application written and deployed to the phone. In the afternoon we looked into sending an SMS from JAVA using the messaging API…. And this is fairly easy.

For more details on the course see: http://uie.bit.uni-bonn.de/developing.php

Seeing the possibilities of JAVA ME and how quick people get applications running made me wonder how long it takes till we have massive mal-ware, viruses and spam on the phone. Secutity on phones may be one of the upcomming challenges.
