Fig. 2From: Does changing Fitts’ index of difficulty evoke transitions in movement dynamics?Angle diagrams. The upper versus lower two rows represent angle diagrams from a single participant of the discrete and cyclic mode, respectively. For both row pairs, the upper panels show the distance conditions while the lower ones display the width conditions. ID e increases form left to right. The colour coding (at the right) represents the maximal angle between neighbouring vectors. Red areas indicate locally opposing angles, implying the existence of a fixed point. Their absence suggests the existence of a limit cycleBack to article page
