Computational model. ChackochanVinil T. SanguinetiVittorio 2019 <p><b>(a)</b> Two players jointly control dyad dynamics (approximated as two mass-points connected by a spring). Each player has a separate sensory system which provides information about dyad state. The controller includes a state observer, a feedback controller and an estimate of the partner’s control action (partner model). <b>(b)</b> From left to right: Interaction force and minimum distance from VP<sub>1</sub> (<i>MD</i><sub>21</sub>) and VP<sub>2</sub> (<i>MD</i><sub>12</sub>), for all three H, VH and PV scenarios. <b>(c)</b> Leadership index for player 1 and player 2 at VP<sub>1</sub> (left) and VP<sub>2</sub> (right) for all three H, VH and PV scenarios.</p>
