The Fitts’s law test. a The 40 combinations of target positions and radii selected for the current study. No target was placed on any of the coordinate axes, thus requiring the subject to activate both DoFs, either sequentially or simultaneously, for successful task completion. b Screen capture of the view of a subject while steering the cursor towards one of the targets presented during the test. The red ‘tail’ tracking the cursor represents the positions occupied during the preceding 0.3 s (60 samples at the 200 Hz sampling rate). A target was considered reached after a dwell time of 0.3 s, i.e. when the entirety of the tail was situated within the target periphery
