Ethics as material for innovation – German HCI conference – Mensch und Computer

On Tuesday I was at the German human computer interaction conference called Mensch und Computer. The keynote by Alex Kirlik was on Ethical Design (slides from his talk) and he showed how ethics extends beyond action to technology leading to the central question: Why should we build certain systems? His examples and the following discussion made me wonder whether „Ethics become the next Material for innovation“. Taking his example of 9/11 where old technology (air planes) and a different view on ethics was used to strike this is in contrast to previous/typical warfare where new technologies (e.g. Gun powder, Nuclear bomb) have changed the way wars are conducted.

Considering ethics as material for innovation is obviously risky but looking at successful businesses of the last decade such a trend can be argued for (e.g. google collecting information about the user to provide new services, youtube allowing users to share content with limited insurance that it is not copyrighted). Would be interesting to have a workshop on this topic sometime in the future…

Grace who left our group after finishing her Master’s degree (to work in the real world outside of university 😉 presented her paper on how to aid communication in the car between driver and passenger [1].

In the afternoon the working group on tangible interaction in mixed realities (in German Be-greifbare Interaktion in Gemischten Wirklichkeiten) had a workshop and a meeting. We will host the next workshop of the working group in Essen early next year (probably late February or early March).

PS: the next Mensch & Computer Conference ist at the University of Duisburg-Essen 🙂

Special issue of I-COM on automotive user interfaces

Together with Susanne Boll and Klaus Bengler I was guest editor for a special issue of the I-COM magazine on automotive user Interfaces. The papers are largely in German (but there are English abstracts available). The special issue shows different examples of work in this domain.

Dagmar and Stefan have a paper that describes the CARS driving simulator and its application [1]. Together with Stefan and Wolfgang from BMW research I published a paper on search interfaces in the car [2] – which was originality investigated in two master theses in Munich and also discussed in a CHI Note [3].

More surface interaction using audio: Scratch input

After my talk at the Minerva School Roy Weinberg pointed me to a paper by Chris Harrison and Scott Hudson [1] – it also uses audio for creating an interactive surface. The novelty on the technical side is limited but nevertheless the approach is interesting and appealing because of its simplicity and its potential (e.g. just think beyond a fingernail on a table to any contact movement on surfaces – pushing toy cars, walking, pushing a shopping trolley…). Perhaps having a closer look at this approach a generic location system could be created (e.g. using special shoe soles that make a certain noise).

There is a youtube movie: http://www.youtube.com/watch?v=2E8vsQB4pug

Besides his studies Roy develops software for the Symbian platform and he sells a set of interesting applications.

CfP: What can the Internet of Things do for the Citizen?

Together with Stephan Karpischek (ETH Zurich) and Florian Michahelles (ETH Zurich & Auto-ID labs) I organize a workshop at Pervasive 2010 in Helsinki looking for an end-user perspective on the Internet of Things.

The call is online at: http://www.autoidlabs.org/events/ciot2010 and the deadline is the 15th of January 2010.

The topics that we hope for include emerging applications, interaction paradigms, infrastructure, and social impact of new technologies and the implications for citizens.

Students generate interesting ideas, links to photos

In the final part of the summer school the students worked in groups to create new ideas for displays and their use. We had 5 groups working hard – all creating amazing results for such a short time. Sometimes I wonder how we could better utilize this design exercise as the results were really exciting.

On group looked into the concept of mobile and contextual displays on garments – the idea T-SHARE assesses potential applications, when having networked displays included in T-Shirts (see the group presentation for details). This moves an idea with have investigated over the last year to a new level. I am really thrilled and I think we should really look how to setup a larger project on this topic.

We worked hard 🙂 but in the time between we enjoyed our trip – here are the photos I took (Bahai Garden, climbing with Keith and Antonio, the trip to Jerusalem, School and Beach in Haifa).

Taking pictures during sports – ideas for an appliance


If you do sports it typically requires another person to take the photos of you. Having the evening off in in Haifa Keith, Antonio and me went climbing at http://www.shafan-hasela.com/. It was not easy to get there – we used the typical way – first: take a bus to a random place (not intentially) – second: realize that the bus went to a place you did not want to go – third: take the taxi to where you wanted to go.

Being three people it was very easy to takes pictures while climbing – and I as I am climbing a class below Antonio and Keith I had a lot of time to take the pictures 😉

Being computer scientist you always think about cool, challenging, and exciting projects. So we wondered if we could build an autonomous flying object that contains a camera that follows you (in a defined distance) and takes exciting photos. We have an idea how this could be done – let me know if you would be interested in the project (e.g. bachelor/master)- may be even done in a collaboration with Lancaster.

Interaction technologies for display environments

I was invited to give a talk on „Embedded interaction with display environments“ to discuss human computer interaction and technology issue for creating interactive display systems. The summer school has very diverse program! and I have enjoyed listening to my colleagues as much as presenting myself 🙂

In the talk I have a (more or less random) selection of technologies for making display environments interactive. There are the obvious vision based approaches (see the talk for the references) but I think there are many interesting approaches that are not yet fully explored. – including spatial audio location [1], eye tracking, and physiological sensors. Sebastian Boring create a focus and context input by combing different input technologies [2] – this can be especially interesting when scaling interaction up to larger surfaces. Additionally I think looking at the floor and the ceiling is worthwhile…

Please feel free to add further technologies and approaches for creating interactive displays in the comment.

It is better to look beautiful… Aesthetics and HCI

During the summerschool in Haifa Prof. Noam Tractinsky from Ben-Gurion University of the Negev gave a presentation about Aesthetics in Human-Computer Interaction. It was good to meet him in person and get some more insight in his work – as I refer to it typically in my HCI class.


In short his finding can be summarized by: What is Beautiful is Usable [1], [2]. In his talk he had some interesting example – you can look at a web page for one second only and you will figure out if it is a good design or not. There has been previous work in Japan [3] similar results – suggesting that this may be universial. Methodical I think the research approaches are not straightforward and may be disputed in parts – but the basic findings are very intuitive and should be taken more into account.

Interact 2009, Never been to Uppsala

Uppsala in Sweden is still one of the places I have never been to – and this year I missed another chance: Interact 2009

From our group Florian was there an presented his paper on a parasitic applications for the web [1]. We also published joined work with ETH Zürich on a comparison of product identification techniques on mobile devices [2]. Heiko Drewes has submitted his PhD thesis on Eye-tracking for interaction and one of the early projects he did was now published at Interact. The idea is that the mouse courser is positioned to the position where your eye-gaze is in the moment you touch the mouse [3]. Interact 2009 was quite competetive as it had an acceptance rate of 29% for research papers.
