Joint action



When moving in space, non-verbal interaction and coordination processes with other persons in the environment continuously take place to avoid potential collisions – a process referred to as "joint action". Joint actions impose special demands on cognitive and motor functioning of the interacting persons. Yet, the underlying principles of interpersonal coordination during human locomotion and the effect of age-related functional decline on joint action are only poorly understood.


Optical motion tracking to calculate kinematic parameters of persons‘ gait (e.g. speed and path adjustments, minimum distance) 

Modelling approaches to predict different outcome measures of movement adjustments (e.g. crossing order)

Questionnaires to assess the persons‘ perception of the interaction
