Cooperation Day – “Business meets Science”

On September 5th the IBS Cooperation Day – “Business meets Science” took place at the IBS Foundation in Laubusch / Lusatia in Germany which was founded to improve the computer science collaboration in Saxony and across it’s country borders. The event chaired by Prof. Hardt of the Computer Engineering department in Chemnitz took place in a reworked coal production management building. Anke Tallig and Kai-Uwe Martin of our research training group presented the general concept of “CrossWorlds” and the project “Mediator – Ambassador in mixed reality” to an interested audience of scientific colleagues and representatives of companies and politics, most notably Saxony’s prime minister Stanislaw Tillich who showed a special interest in the interdisciplinary aspect.

Presentation of CrossWorlds

Through conversation with other researchers, e. g. the robotics team of Prof. Böhme of Dresden University of Applied Sciences that works in areas like environment modeling, self-localization, and person perception and
various other scientists our different approaches to human machine interaction were analyzed. Chances and risks of the current technologies and future potential of our work were discussed and personal connections


INTERACT 2013 – Paper Presentation


INTERACT 2013 – Opening Plenary


At this year’s INTERACT conference crossWorlds presented the publication ‘Diverse Ecologies – Interdisciplinary Development for Cultural Education’. Within their work crossWorlds researchers Heidt, Kanellopoulos, Pfeiffer and Rosenthal explore the implications of highly interdisciplinary research settings. Showing how differences between project participants can act as assets, they argue for a design process infused by multiperspectivity, disciplinary diversity and mutual sensitivity. The presentation at Cape Town, South Africa was met with a high amount of interest and sparked many engaging scientific discussions.
INTERACT’s motto ‘conference with a conscience’ also provided a helpful climate for articulation of ethical motivations underwriting design processes at crossWorlds. The conference thus provided a unique venue for discussion of ethical commitment as well as practical design. Hence, experiences made, positions exchanged and insights acquired have proven to contribute invaluably to ongoing research. Situated within multi-cultural Cape Town, INTERACT attracted participants from 37 countries, contributing to an atmosphere of diversity, curiosity and mutual tolerance.


Mensch und Computer 2013

This years edition of Germany’s primary conference on human computer interaction “Mensch und Computer” took place in bremen with high involvement of CrossWorlds’ researchers. Since the conference character emphasizes interdisciplinary exchange between academics, practioners, computer scientists, UX designers and social sientists several of our research fellows participated actively in the event.

Andreas Bischof and Benny Liebold organized a workshop on methodological approaches to HCI, where Kalja Kanellopoulos and Michael Storz presented their multitouch table for multiple users (Kanellopoulos, Storz 2013, in press). A very interesting discussion about the outlines of a possible mutual methodology for both computer scientists and designers / social scientists was initiated by Michael Heidt‘s talk (Heidt 2013, in press). The main talking points can be understood in two (german-language) blog posts. One is pointing out the question, how qualitative data and results can be communicated more compatible for HCI projects, the other sums up a discussion on interdisciplinary communication around code between computer scientists. A literally visionary (and entertaining) submission from TU Chemnitz researchers beyond that was the visual computing group‘s video on a possible HCI avatar tool in the shape of cuddly toys.


8th Conference of the Media Psychology Division of the German Psychological Society, Sept. 4–6

Last week, CrossWorlds fellows Benny Liebold and Daniel Pietschmann went to Würzburg  to present research papers with their respective working groups on “Emotionally Neutral Cues in Virtual Agent’s Expressive Behavior Impair Recognition of Emotions in Other Modalities” (Liebold) and “Effects of Video Game GUIs on the Construction of Rich Spatial Situation Models and Spatial Presence” (based on the Masters Thesis of and presented by Steve Nebel) at the 8th Conference of the Media Psychology Division of the German Psychological Society. Further talks included “Social Interaction in Massively Multiplayer Online Games: An Evolutionary Perspective” (Pietschmann), “No Evidence for Persuasion Effects of Emotional Advertisement on Attitudes towars Social Groups – The Case of Ageism” (Liebold) and “Gaze Path Analysis of Differences in Task Related Perception of Data Visualization” (Müller). Daniel also participated in the PhD Workshop the day before the conference.

We had a great time at the lab of Prof. Frank Schwab and colleagues in Würzburg and thank the organizers for putting together a great conference for the Media Psychology Division this year.


Affective Computing and Intelligent Interaction 2013, Geneva, Sept. 2–5

With the biannual conference on Affective Computing and Intelligent Interaction that aims at the intersection of research on human emotion and computational models of emotion, research on emotion both in humans and virtual entities found an important platform for interdisciplinary exchange. This year the 5th conference was held in Geneva, Switzerland, on September 2–5.

On Thursday, September 4, CrossWorlds fellow Benny Liebold gave a talk on “Multimodal emotion expression of virtual agents. Mimic and vocal emotion expressions and their effects on emotion recognition”. The talk addressed human recognition of emotion expressions of virtual agents. It was found that our ability to recognize emotional states from virtual agents is worse when virtual agents use unimodal expressions of emotions compared to multimodal expressions. Even more interestingly, unimodal expressions of emotions together with neutral nonverbal cues are recognized worse than isolated unimodal expressions of emotions. The latter might be a result of users perceiving the neutral expression of virtual agents as a relevant component of the virtual agent’s emotional state. Further results can be obtained from the conference proceedings, which are going to be indexed in IEEE Xplore.

A total number of 55 papers covered a vast area of research from psychological research in human emotions to computational models of emotional processes, such as empathy and automated emotion recognition. We thank the Computer Vision and Multimedia Laboratory and the Swiss Center of Affective Sciences from Geneva University, who did a great job in organizing the conference, putting together a great conference program including the very interesting keynote speakers.


HCI International 2013, Las Vegas, July 21–26


This July the CrossWorlds fellows Anke Tallig, Michael Heidt and Michael Storz presented their paper submissions at the HCI International 2013 Conference in Las Vegas. With its two different thematic areas and nine affiliated conferences the conference had a very broad scope on many different aspects of human computer interaction. The large amount of submissions (1666 Papers and 303 Posters) gave attendees the opportunity to choose between many parallel sessions.

CHI ’13 – CrossWorlds Presentation & Workshop-Panel


CHI ’13 Opening Plenary

crossWorlds fellows Kalja Kanellopoulos and Michael Heidt were invited to present their paper ‘Stubborn Materialities / Unruly Aesthetics’ at CHI ’13. The participation in the workshop ‘Crafting Interactive Systems’ included a talk as well as acting as panellists for the session ‘technology as critique’. Focussing on a reconceptualization of the relationship between artistic and scientific practices, both researchers explored the potentials inherent in digital materialities. According to their positions, displacements introduced by interactive art open new expressive possibilities for aesthetic unmasking of power relations. The presentation sparked lively discussions as well as obtaining strongly positive feedback.
Throughout the conference, the field of HCI articulated itself as driven by a highly dynamic community. An atmosphere of openness towards heterodox thought was perceived as helpful intellectual catalyst, creating exciting opportunities for integration of scientific, artistic and designerly practices.
ACM CHI is widely acknowledged as the most prestigious conference in the field of Human-Computer-Interaction. This year’s CHI was the largest and most multicultural event hosted so far with around 3300 attendees, representing a total of 54 nations.
