Christian Seegelke, Charmayne Hughes, Andreas Knoblauch, Thomas Schack , "Grasp posture planning during multi-segment object manipulation tasks -interaction between cognitive and biomechanical factors", Acta Psychologica, vol. 144, pp. 513-521, 2013.
AbstractThe present study examined the planning of initial grasp postures during a multi-segment object manipulation. Participants performed a grasping and placing task that consisted of one, two, or three movement segments. The position of the targets was manipulated such that the degree of object rotation between the home and temporally proximal position, and between the temporally proximal and distal target position varied. There were four main findin...

Lars Gräning and Thomas Ramsay , "Quantifying Vector Field Distances Based on a Reduced Stream Line Representations", Int. Conf. on Intelligent Data Engeneering and Automated Learning (IDEAL), pp. 445-454, 2013.
AbstractIn the automotive industry Computational Fluid Dynamics (CFD) simulations have become an important technology to support the development process of a new automobile. During that process, individual simulations of the air flow produce a huge amount of information about the design characteristic, where mostly only a minority of information is used. At the same time knowledge about the relationship between design modifications and their aerodynamic ...

Karola Pitsch, Anna-Lisa Vollmer, Manuel Mühlig , "Robot Feedback shapes the tutor's presentation. How a robot's online gaze strategies lead to micro-adaptation of the human's conduct", Interaction Studies Special Issue: Asymmetry and adaptation in social interaction A micro-analytic perspective, vol. 14, no. 2, pp. 268-296, 2013.
AbstractThe paper investigates the effects of a humanoid robot’s online feedback during a tutoring situation in which a human demonstrates how to make a frog jump across a table. Motivated by micro-analytic studies of adult-child-interaction, we investigated whether tutors react to a robot’s gaze strategies while they are presenting an action. And if so, how they would adapt to them. Analysis reveals that tutors adjust typical “motionese” parameters (pau...

Nikolas Hemion, Frank Joublin, Katharina Rohlfing , "Developmental Integration of Sensorimotor Mappings", ROBOTDOC International Conference on Development of Cognition, 2013.
AbstractSensorimotor mappings, such as kinematic transformations or control policies, are essential tools for robots to solve tasks. In the developmental robotics and machine learning literature, the question of how robots can learn sensorimotor mappings from own experiences is often investigated, enabling robots for example to learn to reach for objects, to balance poles or to swing tennis rackets. However, the important problem of how multiple sensorim...

Martin Ernst Heckmann , "Steps towards a more natural and intuitive communication between humans and machines ", Dagstuhl Seminar: Computational Audio Analysis, Schloss Dagstuhl, Leibniz Zentrum für Informatik, 2013.
AbstractCurrent speech interfaces are perceived as little intuitive and error prone. In this talk I will present different strategies to make the human-machine interface more intuitive and less fragile by enriching the range of information available to the machine and tolerating changes in the acoustic environment. This includes features more robust against noise and approaches to capture prosodic variations. I will start with the hierarchical spectro...

Maha Salem, Stefan Kopp, Frank Joublin , "Closing the Loop: Towards Tightly Synchronized Robot Gesture and Speech", International Conference on Social Robotics (ICSR), 2013.
AbstractTo engage in natural interactions with humans, social robots should produce speech-accompanying non-verbal behaviors such as hand and arm gestures. Given the special constraints imposed by the physical properties of a humanoid robot, successful multimodal synchronization is difficult to achieve. Previous work focusing on the production of communicative robot behavior has not sufficiently addressed the challenge of speech-gesture synchrony. Introd...
