It seems this term we picked a good slot for the lecture. On Thursday we had Prof. Silvia Miksch from Vienna University of Technology visiting our institute. We took this chance for another guest lecture in my advanced HCI class. Silvia presented a talk with the title “A Matter of Time: Interactive Visual Analytics of Time-Oriented Data and Information”. She first introduced the notion of interactive visual analytics and then systematically showed how time oriented data can be visually presented.
I really liked how Silvia motivated visual analytics and could not resist to adapt it with a Christmas theme. The… Continue reading
In the CHI community we have the notion of non-archival publications. Some years back this concept may have been good but I find it harder and harder to understand. Over the month I had several people about this concept and in Paris I discussed it with several colleagues, who are involved in SIGCHI. Here are some of the thoughts – hopefully as a starting point for further discussion.
First a short introduction to the concept of Non-archival publications: non-archival publications in the “CHI world” are papers that are published and shown at the conference, but that must not be… Continue reading
Florian Alt defended his PhD thesis “A Design Space for Pervasive Advertising on Public Displays” at the University of Stuttgart. Over the last years Florian work at the crossroads of interactive public displays and pervasive advertising. His research output during the last years and while working on the http://pd-net.org project was amazing, see his DBLP entry.
The dissertation will be soon available online. If you are curious about his work right now, there are a few papers or a book you should read. A high level description of the findings is described in a paper published in… Continue reading
In 2013 the 4th Augmented Human Conference will talk place in Stuttgart, Germany. The submission deadline is January 8, 2013 and the conference is in cooperation with ACM SIGCHI. The papers will be published in the ACM digital library. Andreas Bulling and Christian Holz are the program chairs and there is a fabulous technical program committee.
With AH2013 we continue a Conference that over last years has ventures beyond the usual things in human computer interaction and pervasive computing. Improving and augmenting human abilities is at the core of the conference, ranging from navigation systems, to actuator that help… Continue reading
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:
- The reviewers are usually more careful in what they write as they know they have to face a response for the authors
- 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
Karin Bee (nee Leichtenstern) has defended her dissertation at the University of Augsburg. In her dissertation she worked on methods and tools to support a user centered design process for mobile applications that use a variety of modalities. There are some papers that describe her work, e.g.  and . To me it was particularly interesting that she revisited the experiment done in her master thesis in a smart home in Essex  and reproduced some of it in her hybrid evaluation environment.
It is great to see that now most of our students (HiWis and project students) who worked… Continue reading
This year’s ACM MobiSys conference is in the Lake District in the UK. I really love this region in the UK. Already 15 years back when I studied in Manchester I often came up over the weekend to hike in the mountains here. The setting of the conference hotel is brilliant, overlooking Lake Windermere.The opening keynote of MobiSys 2012 was presented by Dr. Paul Jones, the NHS Chief Technology Officer who talked about “Mobile Challenges in Health”. Health is very dear to people and the approach to health care around the world is very different.
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
Kenton O’Hara, a senior researcher in the Socio-Digital-Systems group at Microsoft Research in Cambridge, presented the keynote at the pervasive displays symposium in Porto on the topic “Social context and interaction proxemics in pervasive displays“. He highlighted the importance of the spatial relationship between the users and the interactive displays and the different opportunities for interaction that are available when looking at the interaction context.
Using examples from the medical field (operating theater) he showed the issues that arise from the need of sterile interaction and hence avoiding touch interaction and moving towards a touchless interaction mode. A prototype,… 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 afternoon we (over 40 people from VIS and VISUS at the University of Stuttgart) went to Karlsruhe to visit the ZKM. We got guided tours to the panorama laboratory, the historic video laboratory, to the SoundARt exhibition and some parts of the regular exhibition. Additionally Prof. Gunzenhäuser gave a short introduction to the Zuse Z22 that is in on show there, too.
The ZKM is a leading center for digital and media art that includes a museum for media art and modern art, several research institutes, and an art and design school. The approach is to bring… Continue reading
It is 50 years now that Prof. Rul Gunzenhäuser, my predecessor on human computer interaction and interactive systems at the University of Stuttgart, defended his PhD. Some month back I came across his PhD thesis “Ästhetisches Maß und ästhetische Information“ (aesthetic measure and aesthetic information) , supervised by Prof. Max Bense, and I was seriously impressed.
He is one of the few truly interdisciplinary people I know. And in contrast to modern interpretations of interdisciplinary (people from different working together) he is himself interdisciplinary in his own education and work. He studied Math, Physics and… Continue reading
If you share an apartment with a friend you know what they do. There is no need to communicate “I am watching TV” or “I am cooking” as this is pretty obvious. In the digital space this is much more difficulty. Sharing what we engage with and peripherally perceive what others do is not yet trivial.
Niels Henze and Alireza Sahami in our group have made a new attempt to research how to bridge this gap. With the AppTicker for Android they have released a software, that offers means to share usage of applications on your phone with your friends… 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 ( and ) and public display systems . Florian got together with the researchers from T-Labs a best paper award for .
Please have a look at the papers… I think it is really worthwhile.
Increasing the security of gaze-based graphical passwords “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  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
At the Museum of the Weird in Austin Lars Erik Holmquist hosted a book launch party for his book: Grounded Innovation: Strategies for Creating Digital Products. The book uses a good number of research examples to highlight the challenges and approaches for digital products. The book has to parts: Methods and Materials and shows how both play together in the design of digital products. There is a preview for the book at Amazon.
Margaret Gould Stewart, a highly regarded user experience designer currently leading UX design at YouTube, presented the opening keynote at CHI2012. She started her talk with reminding us that humans are story tellers – they always have been and probably always will. What is not constant is the medium – as technologies change so do means for storytelling and sharing.
The topic started out with talking about video connects the world. It extended to a larger view – changing the world through experience design (in the context of video). I often wonder what designers are and she added… Continue reading
Welcome to our new website and blog!
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
Dagmar Kern has successfully defended her PhD on “Supporting the Development Process of Multimodal and Natural Automotive User Interfaces” in Essen. External examiner was Antonio Krüger from University of Saarbrücken. Her dissertation will be available online soon. The core contribution of the thesis is the investigation of how to improve a user centered design process for automotive user interfaces. In order to systematically assess user interface designs in cars she developed a design space (inspired by Card et al ). In various cases studies she create novel in-car user interfaces and explored experimentally the implications on driver distraction.
Dagmar started… Continue reading
