Summary of cursor movement and target selection performance for each user. A: Accuracies for cursor movement (black), target selection (light gray), and their combination (dark gray). The percentage for the combination is based on the conditional probability of correct cursor movement given a selection. This illustrates that combining the cursor movement and selection tasks improved net accuracy in each user. B: The percentage of total trials in which the correct target was selected (black), no target was selected (light gray), or an incorrect target was selected (dark gray). In all users, the worst outcome, incorrect selection, is relatively uncommon, and much less common than the neutral outcome, no selection.
