Talk of Harald Reiterer at the Cognitive Systems Colloquium at Ulm University

Harald Reiterer will give a talk about “Blended Interaction: Understanding Natural Interaction in Post-WIMP Interactive Spaces” at the Cognitive Systems Colloquium at Ulm University on January 25.

Review to Mensch und Computer 2017

This year’s “Mensch und Computer” took place in September and was themed under the
slogan “Spielend einfach interagieren”. Host-city was Regensburg. Carla Groeschel and Katja
Vock participated as Student Volunteers and thereby ensured a smooth procedure of the
conference as part of the team. Jonathan Wieland presented the paper “Loci Spheres: A
Mobile App Concept Based on the Method of Loci”. The method of loci is an effective
technique to support the memorization and retrieval of information. The publication
investigates, in which way the application of the technique can be supported by mobile
devices. Therefore, three variants of the app “Loci Spheres” are introduced. In an in-the-wild
study perceived system support, usage behavior, and effectiveness of the three variants are

Rebuild Palmyra? at EVA Berlin 2017

In November Moritz Skowronski presented Rebuild Palmyra? – Zukunft eines umkämpften Welterbes? at the EVA Berlin 2017 (Electronic Visualization and the Arts). There he showed how the Augmented and Virtual Reality exhibits we built for the exhibition „Rebuild Palmyra?“ fit into the vision of Blended Museum.





Webstrates Workshop and Talk of Clemens Nylandsted Klokmose

We are pleased to welcome Clemens Nylandsted Klokmose and Roman Rädle from Aarhus University this week!

During a two-day workshop (Wednesday and Thursday), Clemens and Roman will introduce Webstrates and Codestrates from a technical point of view, we will experience these platforms during hands-on sessions and we will discuss how we could use Webstrates and Codestrates for future prototypes, systems, and evaluations to foster collaborations.

As part of the workshop and our SFB Lecture Series, Clemens will give a talk about “Shareable Dynamic Media: A revisit of the fundamentals of interactive computing?” The talk will be held on Wednesday, November 15 at 4.00 pm in room C202.

Developing interactive systems that support collaboration between people, distribution across heterogeneous devices and user appropriation is notoriously difficult. Today’s software rests on a foundation built for personal computing, and to properly support the aforementioned qualities we need to revisit this foundation. In this talk, I will present you with a vision called Shareable Dynamic Media, inspired by Alan Kay’s seminal vision of Personal Dynamic Media. I will present a prototype implementation of the vision called Webstrates, and demonstrate how it enables the development of software where distribution across devices, collaboration between people, and malleability and reprogrammability are the norm rather than the exception. I will show our latest project, Codestrates, that combines Webstrates with the literate computing approach of interactive notebooks.

Clemens Nylandsted Klokmose is an associate professor in the development of advanced interactive systems at the Department of Digital Design and Information Studies, at the School of Communication and Culture, Aarhus University. He co-directs the Digital Creativity Lab that is part of the Center for Advanced Visualisation and Interaction (CAVI). Clemens has worked as a postdoc at Computer Science, Aarhus University and at Laboratoire de Recherche en Informatique, Université Paris-Sud. He has furthermore spent a year as a user interface specialist in the industry. Clemens received his PhD in Computer Science in 2009 from Aarhus University supervised by prof. Susanne Bødker.

Clemens’ main interest is the fundamentals of interactive computing, particularly to support and understanding computing with multiple devices and multiple people. Many of his ideas are crystallised into the Webstrates platform (, which he leads the development of.

Talk of Kasper Hornbæk: ‘What is the interaction in human-computer interaction?’ on November 6, 2017

We are pleased to welcome Kasper Hornbæk from the University of Copenhagen as invited speaker on November 6, 2017. He will give a talk about “What is the interaction in human-computer interaction?”. The talk will be held at 4.00 pm in room C202.


The term interaction is field-defining, yet surprisingly confused. I will talk about different concepts of interaction in human-computer interaction, and how these concepts are associated with different scopes, different notions of goodness, and ways of construing the causal relationships between the human and the computer. Moreover, I will talk about empirical findings concerning interaction and what they show about the open questions about interaction science.


Kasper Hornbæk received his M.Sc. and Ph.D. in  Computer Science from the  University of Copenhagen, in 1998 and 2002, respectively. Since 2009 he has been a professor with special duties in Human-centered Computing at University of Copenhagen. His core research interests are human-computer interaction, usability research, and information visualization; detours include eye tracking, cultural usability, and reality-based interfaces. Kasper serves on the editorial board of ACM Transactions on Computer-Human Interaction. He has published at CHI, UIST, ACM Transactions on Computer-Human Interaction, and Human-Computer Interaction, and won IJHCS’s most cited paper award 2006-2008.
