The talk surveys how to research sophisticated interaction skills in dance, martial arts, sports, bodywork, and related somatic skills. These domains involve variable repertoires, open task structure, and improvisation, yet also require actions to be precise and perfectly coordinated, while agents remain poised for multiple futures. The first part of the talk provides an overview of the demands such skills impose. Notably, constraints of motor control, dynamic interaction management, and improvised decision-making must be met simultaneously.
