In the context of multimodal interaction in ubiquitous computing professor Yoshifumi Kitamura presented a Simtech guest lecture on 3D user interface technologies. His research goal is to create 3D display technologies that allow multi-user direct interaction. Users should be able to move in front of the display and different users should have different perspectives according to the location in front of the display. He showed a set of rotating displays (volumetric displays) that allow for the visual presentation, but not for interaction.

His approach is based on an illusion hole that allows for multiple users and direct manipulation. The approach… Continue reading

ACM SIGCHI has in it’s review process the opportunity for the authors to respond to the comments of the reviewers. I find this a good thing and to me it has two main functions:

  1. The reviewers are usually more careful in what they write as they know they have to face a response for the authors
  2. Authors can clarify points that they did not get across in the first place in the original submission.

We usually write for all submissions with an average score over 2.0 a rebuttal. For lower ranked submissions it may be OK if we think we… Continue reading

Over the last days plans to do research on the use of public date from social networks to calculate someone’s credit risk made big news (e.g. DW). The public (as voiced by journalists) and politicians showed a strong opposition and declared something like this should not be done – or more specifically such research should not be done.

I am astonished and a bit surprised by the reaction. Do people really think if there is no research within universities this will (does) not happen? If you look at the value of facebook (even after the last few weeks) it… Continue reading

While being in the north of England I stopped by in Newcastle at the Culture Lab. If the CHI-conference is a measure for quality in research in Human Computer Interaction Culture Lab is currently one of the places to be – if you are not convinced have look at Patrick Olivier’s publications. The lab is one of a few places where I think a real ubicomp spirit is left – people developing new hardware and devices (e.g. mini data acquisition boards, specific wireless sensor, embedded actuators) and interdisciplinary research plays a central role. This is very refreshing to… Continue reading

This year we have the chance to share some of our research with the community at CHI2012. The work focuses on usable security ([1] and [2]) and public display systems [3]. Florian got together with the researchers from T-Labs a best paper award for [3].

Please have a look at the papers… I think it is really worthwhile.

Increasing the security of gaze-based graphical passwords [1] With computers being used ever more ubiquitously in situations where privacy is important, secure user authentication is a central requirement. Gaze-based graphical passwords are a particularly promising means for shoulder-surfing-resistant authentication, but… Continue reading

After coming back from CHI2012 in Austin I found my paper copy of the April 2012 issue of IEEE Computer magazine in my letter box. This is our special issue on interaction beyond the desktop. Having the physical copy is always nice (it is because I probably grew up with paper magazines ;-).

This guest editors’ introduction [1] is an experiment as we include photos from all papers on the theme. The rational is, that probably most people will not have the paper copy in their hand. When having the digital version the overview of the papers is harder to… Continue reading

In his Keynote “Computing for the Future of the Planet” Andy Hopper brought up 4 topics and touched shortly on each of them: (1) Optimal digital infrastructure – green computing, (2) Sense and optimize – computing for green, (3) Predict and react – assured computing, and (4) Digital alternatives to physical activities.

In the beginning of his talk he discussed an interesting (and after he said it very obvious) option of Green Computing: move computing towards the energy source as it is easier to transmit data than to transmit power. Thinking about this I could imagine that Google’s server farms… Continue reading

I was invited to Leipzig to talk about social networks and in the context of insurance companies (http://www.versicherungsforen.net/social-media). The main focus of the talk was to show what people currently do in social networks and to speculate why they do it (and  I used a picture of the seven deadly sins as an illustrations…) Additionally I discussed some prototypes of activity recognition and their potential once integrated into social media.My talk was entitled “500 Freunde (auf Facebook): Wozu noch eine Versicherung?“ – „500 friends (on Facebook) – Is there still need for insurance… Continue reading

In the Germany the drug store chain Schlecker announced to be insolvent, see the Reuter news post. If you look at the company’s Facebook page and scan the comments from the last 4 weeks it is apparent that some people in the crowd and employees expected it already last year. Schlecker is a large drug store chain with probably over 10.000 outlets in Europe and more than 30.000 employees.

The following screen shots show some selected examples I took from the following page: http://www.facebook.com/schlecker.drogerie The posts are in German – the minimal summary should give you some idea…… Continue reading

The next and 4rd international conference on Automotive User Interfaces and Vehicular Applications (AutoUI 2012) will be in Portsmouth, New Hampshire in the USA. The dates for the conference are 17-19 of October 2012. The first day for workshops and tutorials and 2 days for the main conference. Portsmouth is about an 1 hour drive from Boston and the timing is great (fall foliage – the photos of the colorful forests looked good 😉

The steering committee (sc@auto-ui.org) is inviting proposals for Auto-UI 2013 from the community of researchers in the field. The conference was 2009 in Essen… Continue reading

Bryan started his keynote talk the automotive user interface conference (auto-ui.org) in Salzburg with reminding us that having controversial discussions about the HMI in the car is not new. Quoting a newspaper article from the 1930s on the introduction of the radio in the car and its impact on the driver he picked an interesting example, that can be seen as the root of many issues we have now with infotainment systems in the car.

The central question he raised is: how to create user interface that fit human users? He made an important point: humans are not “designed”… Continue reading

Manfred Tscheligi opend the Automotive UI conference in Salzburg. The conference is now in its 3rd year after 2009 in Essen and 2010 in Pittsburgh. The conference is growing – there were well over 130 people registered 🙂

The proceedings of the conference series are online available at http://auto-ui.org

3rd Auto-UI Proceedings 2011 (soon in the ACM DL) 2nd Auto-UI Proceedings 2010 (ACM DL)1st Auto-UI Proceedings 2009 (ACM DL)

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

On Friday afternoon I had the privilege to present the closing keynote at AMI2011 in Amsterdam with the title ‘Beyond Ubicomp – Computing is Changing the Way we Live’. The conference featured research in Ambient Intelligence ranging from networking and system architecture to interfaces and ethnography. It brought an interesting set of people together and it was good to see many students and young researchers presenting their work.

In my closing keynote at talked about my experience of the last 13 years in this field and about a vision of the future. My vision is based on a… Continue reading

Angefangen hat der Tag um 9 Uhr mit einer Besprechung. Dabei wurde über mehrere Projekte gesprochen und auch darüber was ich die Woche lang machen darf. Das hörte sich sehr vielversprechend an. Continue reading

On Tuesday morning Steve Benford presented the entertainment interfaces keynote. He is interested in how to use computer technology to support performances. Steve works a lot with artist group, where the University is involved in implementing, running and studying the experiences. The studies are typically done by means of ethnography. The goal of this research is to uncover the basic mechanisms that make these performances work and potentially transfer the findings to human computer interaction in more general.

I particularly liked the example of “Day of the figurines“. Steve showed the video of experiences they created and discussed… Continue reading

Ed H. Chi from PARC presented the opening keynote for Mensch&Computer 2010. In the motivation of the talk he showed a document on “Applied Information processing psychology” from 1971 – probably very few had seen this before. It makes an argument for an experimental science that is related to augmented cognition. The basic idea is very similar to Vannevar Bush’s Memex – to extend the human cognitive power by machines (and especially computer technology). It is apparent that these ideas became the backdrop of the many innovations that happened at PARC in the early days.

Ed stressed that there… Continue reading

Andrew Kun invited me to give a talk at the Univeristy of New Hampshire in Durham on my way back from CHI. The talk was on “Embedding Interaction – Human Computer Interaction in the Real World”. In the afternoon I got to see interesting projects in the automotive domain as well as an application on a multi-touch table. At CHI we ran a SIG on Automotive User Interfaces [1].

Seeing the implementation of Project54 live was very exciting. I came across the project first at Pervasive 2005 in Munich [2]. This project is an interesting example of how fast research… Continue reading

Over the last year we looked more closely into the potential of eye-gaze for implicit interaction. Gazemarks is an approach where the users’ gaze is continuously monitored and when leaving a screen or display the last active gaze area is determined and store [1]. When the user looks back at this display this region is highlighted. By this the time for attention switching between displays was in our study reduced from about 2000ms to about 700ms. See the slides or paper for details. This could make the difference that we enable people to safely read in the car… but before… Continue reading

It seems we have a lot of work in progress 🙂 and CHI is a great place to get feedback an talk to people about it.

Florian Alt and others from the summer school in Haifa pushed one of the ideas the developed there further. It is about interactions and technologies to motivate a more thoughtful handling of trash in urban areas [1].

Tanja Döring and Bastian Pfleging developed with Chris Kray in Nottingham the idea of tangible devices that have a functional core and a passive shell [2]. By this we image that future tangible products can be created… Continue reading

EmoDetector, by University of Duisburg-Essen and Nokia Research Center, is an application that provides auditory cues in addition to the notification tone upon receiving an SMS based on a real-time analysis of a message’s contents, see [1].The application responds currently to the following characters sets:

  • 🙂 or 🙂
  • 🙁 or 🙁
  • 😉 or 😉
  • ok (case insensitive)
  • ?

There is a version for Nokia Series 60 phones and for Android, see the download site. Have a look at the http://www.emodetector.tom-lab.de/ website for more information.

2343 attendees came to CHI 2010 this year to Atlanta. Participants are from 43 countries and the colored map suggested that a good number came from Germany. Outside it really feels like spring 🙂

Overall CHI 2010 received 2220 submission across 13 categories of which 699 were accepted. In the paper and nodes categories there were 1345 submissions of which 302 were accepted (22% acceptance rate).

Genevieve Bell from Intel is a cultural anthropologist and she presented the CHI opening keynote with the title: “Messy Futures: culture, technology and research”. She is a great story teller and showed exemplarily the… Continue reading

On Saturday there was a workshop on monitoring, logging and reflecting. Know Thyself: Monitoring and Reflecting on Facets of One’s Life. In the workshop we discussed technologies and concepts for monitoring and using personal information. I started out with asking the question who knows what about you? The list is quickly growing (e.g. telecom provider, travel agent, super market, bank, mail provider, facebook, etc.) and so is the set of information they know about you. And it becomes clear that these entities keep a better record about an individual that the individuals themselves. Hence our central suggestion is that the… Continue reading

Together with Matthias Kranz and Carl Fisher we had a full paper at Percom 2010 – and I had the honor to present it [1]. The paper reports work that explored using the existing DECT (the wireless phone standard) infrastructure (available especially in Europe) as basic technology for localization. We compared DECT and Wifi and it is interesting that in most places you see more DECT based stations than Wifi. Overall it is a really interesting alternative to WLAN location.

From the joint work with Docomo-Eurolabs in Munich in the project AmbiVis we presented a work in progress poster. In… Continue reading

Pertti Huuskonen from Nokia presented his keynote at Percom in Mannheim. I worked with Pertti in 1999 on a European Project TEA – creating context-aware phones [1].

After telling us about CERN and some achievements in physics he raised the issue that an essential skill of humans is that they are context-aware. Basically culture is context-awareness – learning how to appropriately behave in life is essential to be accepted. We do this by looking at other people and by learning how how they act and how others react. “Knowing how to behave” we become fit for social life and this… Continue reading

About 300 people are at Percom 2010, which is held in the palace in Mannheim – and amazing location! The conference had 233 submission and is truly international (1/3 of the papers come from Europe, 1/3 from America, and 1/3 from Asia/pacific) and highly competitive (acceptance rate of about 12%).

Kurt Rothermel from the University of Stuttgart presented the opening Keynote on Large-scale Context Management. He presented a set of interesting example from Nexus (Collaborative Research Center 627, Spatial World Models for Mobile Context-Aware Applications) that showed the challenge in large scale systems. The size of the problem is can… Continue reading
