public spaces

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…

Our group was involved in 3 papers that are published at Pervasive 2009 in Nara.

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 [1].

The second short paper is a survey on car advertising and has been conducted in the context of the master thesis… Continue reading

We got a good set of submission for our workshop and had about 20 participants who joined us in Nara to discuss how pervasive computing will shape advertising in the future. The papers and a selection of talks is online on the workshop website: http://pervasiveadvertising.org

One question that was central to our discussion was: what is advertising and how is it different from information. It became quickly clear that there is a lot of information that has an influence on behavior and in particular shopping decisions and some of it is considered advertising but much is not. Hence it seems… 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

Last winter term I was teaching a class on Unconventional User Interfaces at the University of Linz as part of the MSc in Pervasive Computing. As part of the exercises the students had to do a project and write a paper on the topic in a group. This required to do a full round in the development (from idea creation to study).

Florian König and his group had an exciting idea for a novel form of advertisement. The user is mirrored in the advert and becomes a part of it. They implemented an interactive poster for a travel agent… Continue reading

This evening I went to Münster to meet with Antonio Krüger and Lucia Terrenghi (who is now with Vodafone), who was visiting there. Advertisement is a hot topic and it was interesting that we shared an interesting observation “If the advert/information is the least boring thing to look at people will read it ;-)”. Each of us having their favorite anecdotal evidence: my favorites are people reading the same map everyday at their U-station and the advertising flyers in the Munich S-Train. For context-aware advertisement this is the major challenge to find the time/location where people are bored and happy… Continue reading

In Sydney I saw a legacy-free setup for washing hands in a public bathroom. I was surprised at the simple and solution with high utility! It is only a board mounted in an angle with water taps above. For typical use (washing hands under a flow of water) this is as good as a traditional setup. From looking at it, the legacy-free setup seems much easier to clean. I have never used a washbasin in a public bathroom by filling it – and I have never seen this functionality used (typically you can not use it in the lagacy way… Continue reading

Dagmar presented two work in progress papers at the poster session at CHI. One paper is a master thesis of Hema [1] and assess how we can personalize environments with coding preference into the Bluetooth friendly name. Here we were particularly interested into the acceptance in Germany and India. The second paper [2] was joint work with Nigel’s group from Lancaster. Here we look at targeted poster advertising and how preference information should be stored.

It seems that in the research community a lot of people are convinced of interactive public spaces and interactive window displays. Over the last month I have see great visions and ideas – as well as reflected on our own multi-touch ideas for interactive shop windows.

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

We currently run a survey on “Implicit Personalization of Public Environments” as part of a master thesis. The thesis looks at the technical realization of this approach based on Bluetooth and mobile devices with a focus on creating an acceptable solution with regard to users’ privacy. If you are interested in the topic and can spare 5 minutes have a look at our questionnaire on implicit personalization, there is a German version of the survey, too.

The questionnaire is set up on a server (http://onlineforschung.org) that offers free hosting for scientific/non-profit surveys.

Arriving in Zurich I was quite surprised by the masses of people in the train station. We picked the weekend of the Street Parade for our visit 😉 makes you really think about your own age…

In the railway station they had digital giveaways – you just had to switch your Bluetooth on.

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

The visit to the eCulture Factory showed me again that bringing new media into the real public space creates new and very valuable insights, even though it is difficult and costly. Such installations can give a glimpse of what future public space will be. When thinking of the design space for media in public spaces one can image to create completely different and new experiences. Contextuality and awareness seem key design criteria.

Transforming public space using digital technology offers a lot of chances. However it seems that currently a lot of people think about this mainly with regard to new… Continue reading
