Before revision:  b) MI systems provide improved performance in navigation tasks, improved operator performance in cognitive demanding secondary tasks, and improved operator workload  . Results also reinforce previous Human-Robot interaction (HRI) evidence regarding the importance of the operator's personality traits and their trust in the autonomous system.
After revision:  b) in the context of the simulated robot experiment, Mixed-Initiative (MI) systems provide improved performance in navigation tasks, improved operator performance in cognitive demanding secondary tasks, and improved operator workload . Results also reinforce previous Human-Robot interaction (HRI) evidence regarding the importance of the operator's personality traits and their trust in the autonomous system.
