Experimental set-up. (a) Sensorimotor game. Players were haptically coupled by two handles that generated a force on their hand resisting their forward movement. Importantly, each player's force depended on both players' lateral positions. (b) Pay-off matrices for each one of the three games including pay-offs for player 1 and player 2. The matrix values establish the boundary values of the force pay-offs at the limits of the x1x2-space (left). Interpolation of the pay-offs defines a continuous pay-off landscape for a continuum of actions (right). (Online version in colour.)
