Effect of task on movement distribution. Panel a – Planarity Index computed across tasks: Cal – calibration, Reach = last minute of reaching, Track = tracking task. Constant map group is in black, Adaptive map group in red. * indicate significant differences with p < 0.05. Panel b – Subspace Angle between the subspace of tracking movements and the subspace spanned by reaching movements during the last minute of training, C = Constant map group, A = Adaptive Map group. Panel c – distance between tracking subspace and reaching subspace and the tracking subspace and the BoMI subspace in terms of Subspace Angle. The reaching subspace is computed during the last minute of training. Black dots are individual subjects in the Constant map group, Red crosses are individual subjects in the Adaptive map group. Panel d – example of tracking movement projected onto the subspace obtained from the last 60″ of reaching data in the space of the first 3 principal components (top view) and in the hyperplane of the first two
