Description

Currently, facial and body movements are better controlled and categorized by neural systems than any existing technical framework. Our lab studies the computational principles underlying the control and categorization of body movements in biological systems and transfers them to technical applications, e.g., in computer graphics, humanoid robotics, or biomedical engineering and rehabilitation, where modeling human movements is becoming increasingly important for technical success.

  

Current Projects

Modeling of human robot interaction and use of humanoid robots for rehabilitation training

Modeling of human robot interaction and use of humanoid robots for rehabilitation training

The control compliant robots in interactive tasks, or even in joint tasks with multiple interacting humans and robots is a challenging problem. It is adressed in the EC H2020 project COGIMON by a highly interdisciplinary approach, combining the expertise form groups in neuroscience and robotics engineering. One interaction scenario of this type is also the training of patients by playing an interactive ball game with a humanoid robot. We used biologically inspired algorithms for movement syntheses to control humanoid robots and for training of coordination skills in ataxia.
Probabilistic models for the online-synthesis of emotional and interactive full-body motion

Probabilistic models for the online-synthesis of emotional and interactive full-body motion

Generative probabilistic models of interactive and stylized human motion are applicable in a variety of fields. On the technical side, such models are useful in computer animation, or motion recognition and emotional feature analysis. This work was done partly as parts of the EC FP7 projects TANGO.
Online motion synthesis by networks of learned dynamic primitives for humanoid robots

Online motion synthesis by networks of learned dynamic primitives for humanoid robots

Sequential goal-directed full-body motion is a challenging task for humanoid robots. An example is the coordination of bipedal walking with fast upper body movements.
Development of a Neurally Controlled Hand-Exoskeleton for Functional Restoration Following Brain and Spinal Cord Injuries

Development of a Neurally Controlled Hand-Exoskeleton for Functional Restoration Following Brain and Spinal Cord Injuries

Robots driven by signals from the nervous system represent a promising approach to improving the autonomy and the quality of life of people with disabilities, following, for instance, stroke or spinal cord injury. The aim of the KONSENS-NHE project is the development of a non-invasive, neurally-controlled exoskeleton that may be used in everyday life to compensate for the loss of hand function in people with disabilities.
  

Finished Projects

Smart Eyes: Attending and Recognizing Instances of Salient Events – SEARISE

Smart Eyes: Attending and Recognizing Instances of Salient Events – SEARISE

The core of this artificial cognitive visual system is a dynamic hierarchical architecture, inspired by computational models of visual processing in the brain. Information processing in Smart-Eyes will be highly efficient due to a multi-scale design: Controlled by the brain-inspired model, the active cameras will provide a multi-scale video record of salient events.
Synthesis of complex locomotion behavior for humanoid robots based on biological principles

Synthesis of complex locomotion behavior for humanoid robots based on biological principles

Locomotion in complex situations is a difficult problem in motor control that is unresolved for humanoid robots. We investigate and model how the locomotion behavior of humans is organized for complex locomotion tasks and try to transfer relevant control principles, especially at the level of cognitive control, to humaoid robots. This work is realized within the EC FP7 project KOIROBOT.
Component-based Trajectory Models for Human Character Animation

Component-based Trajectory Models for Human Character Animation

The efficient parameterization of complex human movements is a core problem of modern computer animation. For the synthesis of animations with a high degree of realism learning-based approaches have become increasingly popular.
Dynamical Stability and Synchronization in Character Animation

Dynamical Stability and Synchronization in Character Animation

An important domain of the application of dynamical systems in computer animation is the simulation of autonomous and collective behavior of many characters, e.g. in crowd animation.
Interaction between periodic and non-periodic kinematic motion primitives

Interaction between periodic and non-periodic kinematic motion primitives

In order to provide a highly controlled setup for the recording of arm movements that are coordinated with walking movements, we have developed a novel virtual reality setup combining motion capture using a VICON system and stereoscopic presentation using a setup with Dolby 3D stereo projectors.
