The concept of goal-directed Imitation • Central issue of imitation: • do we imitate movements (means) or consequences (goals) of the observed behavior? • Movements somehow need to be directly mapped (via-point approach), whereas goals need to be represented. • Movement mapping assumes homologue bodies, full access of the whole movement and stable environments. • Goal representation assumes an association between an (observed) action and the (observed) consequence. __________________________________________________________________________________________________________________________________________________________________________________ Project funded by the Future and Emerging Technologies arm of the IST Programme 3FET-”Neuroinformatics for Living Artefacts” under contract No. IST-2000-29689
How to work together? • Behavioral measurements (healthy and clinical patients) • Brain research (single-cell, fMRI, MEG, EEG) • Modeling (Dynamic neural fields) • Robotics (Visual analysis, cognition, and artefact control) • THE solution: One common paradigm __________________________________________________________________________________________________________________________________________________________________________________ Project funded by the Future and Emerging Technologies arm of the IST Programme 4FET-”Neuroinformatics for Living Artefacts” under contract No. IST-2000-29689

Summary • The project combined ... • the development of a new paradigm for goal-directed imitation with imaging studies across all modalities • new findings in experimental neurophysiology and advanced neuromodelling of the structure of the PFC-(STS-PF-F5)-coupling to develop and implement computer-operational models for goal-directed imitation • the development of a powerful model-based hand posture recogniser (using only one B/W camera) • into ... • A complete artefact (robot system) capable of mimicking imitation behaviour of creatures: all project goals have been met! __________________________________________________________________________________________________________________________________________________________________________________ Project funded by the Future and Emerging Technologies arm of the IST Programme 14FET-”Neuroinformatics for Living Artefacts” under contract No. IST-2000-29689
