Presentation of seminar and bachelor/master-project topics

This semester we offer a seminar on ‘Theories & Models in Human-Computer Interaction’ and a number of Bachelor and Master projects in which students have the opportunity to actively participate in ongoing research projects.

We, therefore, cordially invite you to come visit us in our MediaRoom (C203) on Wednesday, October 23rd at 12 pm. There you will get a brief introduction to the contents of the seminar and an overview of open Bachelor and Master projects. The projects will be presented by members of the HCI Group and can be discussed afterwards if any question remains.

Furthermore we would like to advert a seminar from another discipline which is called ‘Exhibition. Inquiries into the museum’ (Ausstellen. Wege ins Museum). Prof. Hauser from the historical science department will introduce you into the interdisciplinary field of museology and strategies for mediation of historic contents. The seminar will be taught in German and aims primarily at master students of architecture, history, computer science, and communication design (HTWG Konstanz). This will be the first event of a new interdisciplinary series of lectures on ‘Public History’ and Museology. The series will be continued by a course on design and architecture of exhibitions (summer 2014, Prof. Schlag, Architecture and Communicative Design, HTWG Konstanz) and on media development and technique (winter 2014/15, Prof. Reiterer, Computer Science, University of Konstanz). So if you are interested in these topics feel free to visit this seminar.

Talk of Thomas Pederson from the IT University of Copenhagen at the University of Konstanz

We are pleased to welcome Thomas Pederson from the IT University of Copenhagen as invited speaker on July, 2nd 2013. He will give a talk about “body-centric modeling of mixed-reality environments”. The talk will be held at 12.00 pm in room Y311.


Embedded and body-worn interactive technology increasingly permeate environments that were previously “digitally dead”. It is becoming harder both for system designers and end-users to draw a line between what is physical (real) and what is virtual (computational/digital). I will present a modeling approach for this emerging “egocentric interaction paradigm” where surrounding infrastructure in a classical Ubiquitous Computing manner is envisioned to adapt itself to the current needs of human agents. The unique features of the proposed approach is the move away from classical Human-Computer Interaction terms such as “input” and “output” to more human-centric “action” and “perception”, opening for a less device-focused perspective on context-aware computing by putting emphasis on human perception, action, and cognitive capabilities. I will exemplify how we have used the model for areas as diverse as activity recognition, multimodal interaction, and (still in the works) illusional user interfaces.


Thomas Pederson is associate professor at the IT University of Copenhagen, researching mobile mixed-reality interaction, tangible user interfaces, and ubiquitous/pervasive computing. Pederson received his PhD in Computing Science from Umeå University, Sweden, in 2003. After various shorter and longer stays at research institutions such as INRIA/IRISA in France and Bari University in Italy, he joined the IT University of Copenhagen in 2009 where is member of the Pervasive Interaction Technology Lab as well as the Interaction Design research group. Pederson regularly serve on conference committees in the areas of Human-Computer Interaction and Ubiquitous Computing and was program co-chair for Tangible Embedded and Embodied Interaction in 2010 at MIT Media Lab (TEI’10) and most recently general co-chair for the 7th Nordic Conference on Human-Computer Interaction (NordiCHI 2012) held at IT University of Copenhagen.

Christian, we wish you all the best and hope you will miss us and return to Konstanz very soon :) .

‘Blended Shelf’ presented at 5. Kongress Bibliothek & Information Deutschland

Today we came back from the “5. Kongress Bibliothek & Information Deutschland” in Leipzig, Germany. With our talk about the “Blended Shelf: Reality-based presentation and exploration of library collections” we gathered valuable feedback from the library community. The event was a good opportunity to get in touch with colleagues and listen to interesting and inspiring talks all across various topics from librarianship.

Thanks to all listeners of the talk for the nice feedback on twitter, such as:

Don’t hesitate to contact us, if you have any questions or more feedback.

Talk of Prof. Dr. Johannes Schöning from Hasselt University at the University of Konstanz

Prof. Dr. Johannes Schöning from Hasselt University will visit the University of Konstanz and will give a talk about “User Identification Techniques for Interactive Surfaces“ on Thu, Mar 7th, in room D432 from 09:00 to 10:00.

We would be pleased to welcome you at this event.



Large touch tables have great potential for co-located collaboration because of their ability to track multiple inputs simultaneously. However, the multi-user experience on these devices can be enriched significantly if touch points can be associated with the user performing an action. When the user’s identity is readily available, there are many new opportunities for systems deployed in multi-user scenarios. For example, multiple users can operate applications in different modes at the same time or the appearance of the interface can change to provide automatic translations or help cues for novice users. In my talk I will give an overview on different techniques and I will present a non-intrusive, high-accuracy technique for mapping touches to their corresponding user in a collaborative environment named Carpus.

By mounting a high-resolution camera above the interactive surface, we are able to extract unique features from the back of the user’s hands, from all hand postures that are common during the practical use of multi-touch systems. Carpus supports walk-up-and-use scenarios in which every touch can be identified transparently. Our system therefore enables an entire new range of applications in which the user’s identity is needed. For example, we envision interactive setups in shops in order for customers to get more information about products. Carpus could be used in this scenario to track the users’ interests over different sessions and suggest them other relevant products in which he might be interested in.


Johannes Schöning is a professor of computer science with a focus on HCI at Hasselt University, working within the Expertise centre for Digital Media (EDM) – the ICT research institute of Hasselt University. In addition he is a visiting lecturer at UCL London within the Intel Collaborative Research Institute for Sustainable Cities. These web pages are intended to give you an overview on his academic activities.

Before that Johannes worked in industry and at the Innovative Retail Laboratory of the German Research Centre for Artificial Intelligence (DFKI) in Saarbrücken. During his time at DFKI he received a PhD in computer science at Saarland University (2010) and a Master in Geoinformatics at the University of Münster at the Institute for Geoinformatics (2007). For his PhD he was awarded with the Vodafone Research Advancement Award.

Johannes Schönings research interests are new methods and novel interfaces to mainly navigate through spatial information. In general he develops, design and tests user interfaces that help people to solve daily tasks more effectively. This includes the development of mobile augmented reality applications, interactive surfaces and tabletops and other “Post-Desktop” interfaces.
