Virtual Ethology and Behaviour Modelling
Early ethology started to abstract the behavior of animals and reduce it to simple cybernetic models. This approach was widely accused of "oversimplification". Another problem was that there were no means to test the functional properties of such models, and therefore the models remained on a descriptive level. But this approach is still valid, and as we will show useful for the analysis of human behavior, because of the appearance of new analysis methods and computing tools which allow us to leave the mere descriptive level of ethological modeling and test human expressive behavior in virtual worlds.
In this context the notion of embodiment plays a primary role - models should not only be computer simulations, they also should correspond to bodily structures which can act in virtual worlds. The reason for this is that there is no cognition without a body and vice versa - the body basically determines the way we think (Pfeifer & Bongard, 1999, Grammer & Oberzaucher, 2008). And we know from robotics that very simple cognitive algorithms can create very complex behavior outputs depending on the physical construction properties of its body. When trying to create the artificial we can gain new insights into the natural. The first part will deal with the construction of expressive virtual embodied agents and what we learned from this.
Then I will demonstrate the use of expressive embodied agents in a variety of scientific contexts like FMRI studies on emotion and body perception (Moser et.al., 2007, Fladung et al, 2009). This then will be extended to the creation of new and controlled stimuli for expression research (Hess et al, 2009, Glauert et al, 2009) in various disciplines. Moreover when motion is added to virtual stimuli various aspects of communication and the internal control architectures can be studied (Grammer & Oberzaucher, 2006, Kopp et al, 2008, Boukricha et al, 2009).
The delineation of control architectures for the agents is central in all these approaches . In order to do so we need the observation of humans in real world everyday activities in ecologically valid situations and create frameworks for the structure of everyday expressive behavior. These theoretical control architectures then can be used to simulate theoretical approaches for instance from appraisal and emotion theory and test them against reality.

Challenges in Computer Animation - From the Virtual to the Real
The field of computer animation continues to provide a variety of technologies to bring virtual characters to life, to support the creation of animated movies, and to enable stunning visual effects in life action films. Yet, there remain a couple of grand challenges for research, which to the present day remain largely unsolved. Such challenges include effective in-betweening in classical 2D animation, the search for more expressive looks in 3D animation, art directable physical animation, or uncanny valley effects in facial animation. More recently, we can also observe a trend towards the synthesis of real 3D animatable objects with controllable mechanical and physical properties. In this talk, I will walk you through some of the grand challenges in computer animation and I will highlight some examples of how we are approaching them at both Disney Research and ETH Zurich.

He has published more than 300 scientific papers and he holds many patents on graphics and visualization technologies. Gross serves on the scientific advisory boards of various international research organizations. He is a fellow of the EUROGRAPHICS Association and a member of the German Academy of Science Leopoldina as well as of the Berlin-Branderburg Academy of Sciences. He received the SWISS ICT Champions Award in the category People in 2011.
NVIDIA Best Paper Award
This year, NVIDIA is sponsoring the best paper award. The NVIDIA Best Paper Award will be provided to the paper that obtains the best score during the review process and attracts most attention at the conference. The award winner will be choosing either a Quadro 6000 or a "Cardhu" development kit for the Tegra3 mobile processor as the prize. The runner-up award is sponsored by Intel. An SSD will be provided to the winner as a prize.
Below are the results of the awards along with papers receiving honourable mentions. These papers will be invited to have extended versions appear in a TVCG Special Section.
