Kinematic metrics. Kinematic metrics for the different phases of the experiment averaged over all subjects and all steps: (a) average weighted position error in the x direction (e p ), (b) average correlation coefficient between velocity profiles in a phase compared to the mean velocity profile in baseline (c p ), (c) average travel time (t p ). The error bars represent the inter-subject standard deviation, i.e. the standard deviation computed in each phase by using the metric of each subject as data set. The gray area indicates phases with exposure to the force field, asterisks indicate a significant difference with the baseline
