Back from CHI 2016

We are back from CHI 2016 and happy to present some impressions:

Harald Reiterer and Mario Schreiner co-organized Cross-Surface 2016, the second international workshop on interacting with multi-device ecologies “in the wild”:

Jens Müller talked about Virtual Objects as Spatial Cues in Collaborative Mixed Reality Environments: How They Shape Communication Behavior and User Task Load (PDF, Video)

Uta Hinrichs and Simon Butscher presented their paper Diving in at the Deep End: The Value of Alternative In-Situ Approaches for Systematic Library Search (PDF, Video).
Together with their co-authors Jens Müller and Harald Reiterer they received an Honorable Mention Award.

Ulrike Pfeil and Johannes Zagermann talked about When Tablets meet Tabletops: The Effect of Tabletop Size on Around-the-Table Collaboration with Personal Tablets (PDF, Video)

Thank you all for a great CHI’16, interesting talks and inspiring conversations!

Presentation of bachelor/master-project topics (HCI Group and Information Science Group)

The Human-Computer Interaction Group (HCI Group, and the Information Science Group (  cordially invite you to come to the introduction of this semester’s Bachelor and Master projects.

You will get a short overview on Monday, April 25 at 11:45 in our Media Room (Z 924).

The offered projects – in which students have the opportunity to actively participate in ongoing research – will be presented by members of the HCI and Information Science Group and can be discussed afterwards if any questions remain.

Invited Talk of Jakob E. Bardram: ‘Activity-based Collaboration for Interactive Spaces’ on March 3, 2016

We are pleased to welcome Jakob E. Bardram from the Technical University of Denmark as invited speaker on March, 3 2016. He will give a talk about “Activity-based Collaboration for Interactive Spaces”. The talk will be held at 5.00 pm in room ML 630.


Activity-based computing (ABC) have been proposed as a novel conceptual and technological framework for designing systems that provide more efficient user interaction. In ABC, rather than interacting directly with lower-level technical entities like files, folder, documents, etc., users are able to interact with ‘activities’ that directly map human work activities, and which encapsulates files and other low-level resources. In ABC an ‘activity’ can be shared between collaborating users and can be accessed on different devices. As such, ABC is a framework that suits the requirements of designing interactive spaces. This talk provides an overview of ABC with a special focus on its support for collaboration (‘Activity Sharing’) and multiple devices (‘Activity Roaming’). These ABC concepts are illustrated as implemented in two different interactive spaces technologies; ReticularSpaces [1] and the eLabBench [3, 2]. The talk discusses the benefits of activity-based collaboration support for these interactive spaces, while also discussing limitations and challenges to be addressed in further research.

Dr. Bardram is a professor in computer science at theTechnical University of Denmark (DTU) and directs the Copenhagen Center for Health Technology (CACHET). Prior to this position, he was a professor at the IT University of Copenhagen (ITU) and an associate professor at the Computer Science Department, University of Aarhus and the co-founder and first manager of the Danish Centre for Pervasive Healthcare.

Dr. Bardram received his PhD in computer science in 1998 from the University of Aarhus, Denmark. During his academic career, he has raised considerable national and european funding for strategic research projects in cooperation with different industrial partners. He has published an edited book on Pervasive Healthcare and has edited several special journal issue on computing systems in healthcare. During his scientific career, Dr. Bardram has published more than 100 original peer-reviewed papers in international scientific books, journals, and conference proceedings. See his Google Scholar profile.

Business Background:

Dr. Bardram has been involved in several start-ups based on his research. Recently (2013) he co-founded and serves as the CEO of the company Monsenso ApS that provides personal health technologies for metal disorders. In 2006, he co-founded the company Cetrea A/S, which specialize in the development of pervasive computing technology for hospitals. He has had several executive roles at Cetrea, including member of the board, chief executive officer (CEO) and chief scientific officer (CSO). Dr. Bardram also helped found CLC Bio A/S who develops bioinformatics software. Dr. Bardram has previously held positions as project manager and IT architect at IBM, and he has been an industrial research fellow at CSC, where he worked with software architectures for cooperative systems in hospitals.

Harald Reiterer at NII Shonan Meeting

Prof. Dr. Harald Reiterer has been invited to a NII Shonan Meeting. The title of the seminar is “Immersive Analytics: A new multidisciplinary initiative to explore future interaction technologies for data analytics”. The seminar will take place from February 15-18, 2016.

Ausstellung: Tell Genderes – 20 Meter Menschheitsgeschichte

In einer Kooperation der Universität Konstanz und der HTWG Konstanz entstand die Ausstellung „Tell Genderes – 20 Meter Menschheitsgeschichte“. Die Studierenden präsentieren Ergebnisse der archäologischen Ausgrabung der antiken Ortschaft Genderes, die im heutigen Norden Syriens liegt.

Er wurde in mehreren Ausgrabungskampagnen von Archäologen aus Konstanz und Syrien untersucht. Sie haben das kulturelle Erbe Syriens (wieder) Schritt für Schritt freigelegt. Frühere Bewohner des Ortes haben mit ihren Hinterlassenschaften Schicht um Schicht den Hügel geformt und so wuchs Genderes immer weiter in die Höhe – der heutige Hügel (arabisch tell) bildet 20 Meter Menschheitsgeschichte ab.

Tauchen Sie in die Welt der Archäologie ein und scrollen Sie durch die Schichten dieses Tells. Entdecken Sie Mönche auf Säulen, den Handel der Antike und die unfassbaren Bauprogramme der Seleukidenherrscher. Die über 5000 Jahre alte Siedlungsgeschichte des Hügels kann ab dem 19.12.2015 im BildungsTURM interaktiv erforscht werden. Dabei wird die aktuelle Lage Syriens nicht aus den Augen verloren.
