Today I had brought 3 more professors with me to teach the class on multimodal interaction (I learned from Hans). As we have the pd-net project meeting Nigel Davies, Marc Langheirich, and Rui Jose were in Stuttgart and ‘volunteered’ to give a talk.
Nigel talked about the work in Lancaster on the use of mobile computing technology to support sustainable travel. He explained the experiments they conducted for collecting and sharing travel related information. In the 6th Sense Transport project they look beyond looking at understanding the current context into predictions and eventually ‘time travel’ 😉… Continue reading
Rui José and Elaine Huang are chairing an international symposium on pervasive displays in Portugal. The conference will be held June 4-5 2012 in Porto. The submission deadline for full papers is January 16th, 2012.
With our research in the PD-net project we encounter many interesting research questions and met with many other researchers interested in the topic. It seems that the many real deployments of electronic displays is fueling ideas and makes it obvious that research is required to understand the properties of this new upcoming media. The call states: “As digital displays become pervasive, they become… 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…
After my talk at the Minerva School Roy Weinberg pointed me to a paper by Chris Harrison and Scott Hudson  – 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… Continue reading
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… Continue reading
Tsvi Kuflik and Antonio Krüger organize from August 30th – September 3rd a German-Israeli Minerva School for Ubiquitous Display Environments: Intelligent Group Interaction, Foundations and Implementation of Pervasive Multimodal Interfaces. I will teach a session on: “Embedded interaction with display environments” and here is the list of recommended readings for the participants – if you are short on time only read the first one and glance over the other two.
Mahato, H., Kern, D., Holleis, P., and Schmidt, A. 2008. Implicit personalization of public environments using bluetooth. In CHI ’08 Extended Abstracts on Human Factors in Computing Systems (Florence,… Continue reading
In the afternoon I gave a talk at NEC labs in Heidelberg on ubiquitous display networks. Over the last year we developed and number of ideas and prototypes of interactive public display systems. We run a lab class (Fallstudien) on pervasive computing technologies and advertising together with colleagues from marketing. In another class (Projektseminar) we investigated how to facilitate interaction between interactive surfaces (e.g. multi touch table) and mobile devices. One of the prototypes will be shown as poster at mobile HCI 2009 in Bonn. In some thesis projects we introduced the notion of mobile… Continue reading
The first contribution is a study on public display that was presented by Jörg Müller from Münster. The paper explores display blindness that can be observed in the real world (similarly to banner blindness) and concludes that the extent to which people look at displays is very much correlated to the users expectation of the content of a display in a certain location .
The second short paper is a survey on car advertising and has been conducted in the context of the master thesis… Continue reading
Sunday night I travelled to Lugano for a meeting public display networks. I figured out that going there by night train is the best option – leaving midnight in Karlsruhe and arriving at 6am there. As I planned to sleep all the time my assumption was that the felt travel time would be zero. Made my plan without the rail company… the train was 2 hours late and I walked up and down for 2 hours in Karlsruhe at the track – and interestingly the problem would have been less annoying if public displays would provide the relevant information …… Continue reading
His work at the cross roads of mobile interaction and public displays is very exciting. In particular he investigates interesting concepts related to visual codes – some aspects to these ideas are discussed in “Swiss Army Knife meets Camera Phone” . His new prototypes are really cool and I look forward to see/read more about them.
We realized that there are many… Continue reading
When I arrived in Seoul at the airport I saw an interesting instance of embedded information. In Munich we wrote a workshop paper  about the concept of embedded information and the key criteria are:
- Embedding information where and when it is useful
- Embedding information in a most unobtrusive way
- Providing information in a way that there is no interaction required
AJ Brush and John Krumm organize for the people who are in Redmond for the Ubicomp PC meeting a visit to Microsoft. In the morning we got a tour at the home lab – Microsoft’s vision of future home environments – was quite interesting, but had to sign an NDA.After lunch we went over to Microsoft Research (which is in a new building). We got to see some cool demos. Andy Wilson showed us some new stuff moving the SURFACE forward (physics rocks!). I learned more about depth sensing cameras and Andy showed a fun application  – there… Continue reading
After the exam board meeting at Trinity College in Dublin (I am external examiner for the Ubicomp program) I went back with Mads Haahr (the course director) to his office. Besides the screen on which he works he has one extra where constantly the log entries of his web server is displayed. It is an interesting awareness devices 😉 some years ago we did a project where we used the IP-address of incoming HTTP-requests to guess who the visitors are and to show their web pages on an awareness display , . Looking back at web visitors works very… Continue reading
The installations I have seen in the real world however are at best boring (and often not functioning at all). It seems that even a student-project-lab-demo is more appealing and works at least as realiable.
Especially combining sensing (e.g. simple activity recognition, context) with low threshold interactive content seems to have great potential. If… Continue reading
Learning that our university has central workshops we went there to talk about our project and to get the mechanical parts built. Our first meeting was really interesting – we got a tour and saw drilling and milling machines as well as a cutter that works with water (can cut glass precisely – extremely impressive). Best of… Continue reading
It was great to spend some time chatting with Alois Ferscha and Gabi Kotsis in Linz. We discussed future forms of advertisement and it seems that it is very clear that pervasive computing technologies – ranging from new displays, to tracking and implicit and explicit interaction – will change our high streets (and any other place where we expect or don’t advertising) in the near future significantly. Looking at current installations we can already see that the race for grapping customer’s attention is on. Given the many ideas around I expect it will be quite exciting.
One interesting movie on… Continue reading
Yesterday we visited the computer science department at the University of Hamburg. Prof. Oberquelle und Beckhaus had invited me at the Mensch & Computer conference to visit them and give a talk about our work.
Before the seminar we had a chance to see the lab of Steffi Beckhaus. I have tried the ChairIO – and it was fun. They sound floor creates a really interesting experience (similar to the butt-kicker just more intense). We could also play with GranulatSynthese and try the smell user interface (apple smell is absolutely convincing, not sure about some of the others).
We… Continue reading
At Zurich Airport Orange and Nokia are running a large printed advert. At a first glance it looks just as a printed large scale poster. The TV screen in one poster and the projected writing on top of another poster are seamlessly integrated. The media design of the overall installation is appealing.
The active screen (could be a 50 inch plasma TV) is the screen of the mobile phone and shows the navigation application. In contrast to most other installations, where screens and printed posters are used, this appears right and it catches people’s attention.
There is work from Scott… Continue reading
I first saw a paper about a context-aware sink at CHI 2005 (Bonanni, L., Lee, C.H., and Selker, T. “Smart Sinks: Real World Opportunities for Context-Aware Interaction.” Short paper in proceedings of Computer Human Interfaction (CHI) 2005, Portland OR).
Yesterday I saw a illuminated faucet in the wild – one which looked in terms of design really great (in the restaurant they even had flyers advertising the product). But after using it I was really disappointed. It uses the concept of color-illumination of the water based on temperature (red hot, blue cold).
The main issue I see with… Continue reading
Antonio Krüger at the University of Münster is running an infrastructure of public displays that show various kinds of information. Using a web editor a select set of people (mainly staff at the department) can input and manage the information chunks that are presented.
In our discussion it became obvious that running such public displays comes with a lot of responsibilities and that people are very quick at complaining about content (may it be censorship or offending content). This leads then to more or less closed and controlled system – but I wonder if we are not overcautious or the… Continue reading
Yesterday we had the opportunity to see a set of research demos at the lab of Antonio Krüger at the University of Münster. We had some time to discuss research projects and in the afternoon Nigel and I gave a talk at the Geoinformatics seminar.
We saw exciting work in progress – a nearly ready large scale multi-touch display based on frustrated total internal reflection – according to Antonio the world-largest at the moment. The principle of operation of such a display is very appealing and the demo was convincing. For a comprehensive introduction on the topic see Jef Han’s… Continue reading
On my way home from Toronto it was surprising how many public displays I saw that provided me with ”information about the future”, e.g. telling me when I will be out of time to cross the road, when the next train is due or when my luggage will arrive. These kinds of predictions or contexts are simple to gather and easy to present and best of all: the human is in control and can act on the information. Overall it is reassuring even if the context information is wrong (this is another story about my luggage ;-).
