Engagement factor, maneuverability factor, and lap time for the three groups.

Groups include participants controlling the boat via the joystick (J), the Kinect in data collecting trials (KC), and the kinect in non-collecting trials (KNC). For engagement and maneuverability factors, the reported values represent the total score obtained from all subjects. For the completion time, instead, mean values (standard deviation) are reported. Values sharing the same superscript in the same column are not statistically different.
