Multiple articles of members of our research group featured in i-com

The german journal i-com – Zeitschrift für interaktive und kooperative Medien features multiple articles of current and former members of our research group in its current issue.

The articles are written in german and can be found here:


i-com is devoted to human-computer interaction, media design, usability, engineering and systems evaluation, software ergonomics, cooperative systems, e-learning, mobile and ubiquitous systems, user-adaptive systems, agent development tools and methods for media in different application fields (including e-business, knowledge management, leisure and entertainment, transport, engineering, and medicine), barrier-free systems design, and the social aspects of information and communication technologies. Disciplines addressed by the journal include computer science, psychology, media design, marketing/branding, sociology, business management, and labor and organizational studies. The journal is an interdisciplinary professional forum for all scientists, business practitioners, and interested parties.
It is devoted to discussing the development, user-appropriate design, and application of new information and communication technologies. The journal seeks to build bridges between research and practice as well as between teaching and business, emphasizing interdisciplinary teamwork and application-oriented solutions. The journal is the official organ of the department of “Human-Computer Interaction” at the German Association for Informatics.

Article about Blended Interaction featured in at – Automatisierungstechnik

The german journal at – Automatisierungstechnik features an article of members of our research group about Blended Interaction in its current issue. at – Automatisierungstechnik publishes articles covering the entire range of automation technology. The journal maintains close ties to research institutes and universities engaged in automation research. It serves the industry as an important guide on matters related to the development of new theoretical methods and their potential areas of application.

Blended Interaction – Neue Wege zur Vermischung realer und digitaler Interaktionskonzepte im Kontext von Leitwarten
Tobias Schwarz, Simon Butscher, Jens Müller and Harald Reiterer

Blended Interaction is introduced as a novel approach to a holistic design of the work environment of control room operators. It addresses a continuously growing complexity of human-machine interfaces in control rooms. The approach bases on the principles of reality-based interaction styles, which emphasize both, the operators with their innate abilities and the work environment’s situational context. In addition, results of an evaluation with user from a traffic control room will be presented in which a potential paradigm shift to new forms of interaction is examined.


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.

2 Papers and Workshop at ITS 2013

Our group contributes two papers and co-organizes a workshop at the ITS 2013 conference which will take place in St Andrews, Scotland from October 6th to October 9th, 2013.

We will present two papers:

Further, we are looking forward to our workshop on Visual Adaptation of Interfaces.

At this workshop, Jens Müller will present another paper:

Talk of Prof. Reiterer at the cooperation event of the Canton of Thurgau and the University of Konstanz

Prof. Dr. Harald Reiterer will give a talk entitled “Die reale Welt als Vorbild – Neue Wege der Interaktion mit digitalen Welten” at the traditional cooperation event of the Canton of Thurgau and the University of Konstanz at the Kantonsschule Frauenfeld on November 20th 2013.

For more information about this event see also this PDF.

We would be pleased to welcome you at this event.

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.
