|
| Many robotics platforms are capable of ascending stairways, but all existing approaches for autonomous stair climbing use stairway detection as a trigger for immediate traversal. In the broader context of autonomous exploration the ability to travel between floors of a building should be compatible with path planning, such that the robot can traverse a stairway at a time that is appropriate to its navigation goals. No system yet presented is ... |

| Today's military pilots are required to perform multiple tasks simultaneously, including maintaining control of the aircraft, navigating, communicating, and detecting targets. Mental workload may affect a pilot's ability to effectively learn to manage these tasks. Studies have shown that there are certain involuntary, physiological changes in eye gaze patterns, such as blink rate, frequency of fixations, and saccade rate that indicate increased mental workload. We hypothesize that experienced pilots, defined ... |
