Terminal feedback regarding time and collisions given to feedback group. Additional feedback regarding the pattern of the movement was also provided. The feedback consisted of the participants’ trajectory overlaid on a 2D diagram of the task viewed from above (Fig. 5a). The locations where participants made collisions (red) or came close to making collisions (blue) were indicated on the diagram. The participants were then shown snapshots of their 3 worst moments (see Fig. 5b for example). The images showed what part of the PW made contact or came close to the obstacle
