Classification of strategies for disturbance attenuation in human-human collaborative tasks

Rigorous analyses of the mechanisms human-human physical interaction are only possible if corresponding means of systematically classifying dyad strategies are in place. Previous suggestions for classification of strategies neglect the high level of redundancy that is present when attenuation of external disturbances is required. To address this, we propose a quantitative classification system based on combined interaction force and EMG recordings of the flexion and extension activities of each partner in a given dyad.
