DETECTION OF OPERATOR PERFORMANCE BREAKDOWN IN A MULTITASK ENVIRONMENT
… 1) to empirically demonstrate an extreme human operator’s state, performance breakdown (PB), and 2) to develop an objective method for detecting such a state. PB has been anecdotally described as a state where the human operator “loses control of the context” and “cannot maintain the required …

Robotic Goal-Based Semi-Autonomous Algorithms Improve Remote Operator Performance
… algorithms are able to improve remote operator performance or not. Two semi-autonomous algorithms were examined: visual servoing and visual dead reckoning. Visual servoing uses computer vision techniques to generate movement commands while using internal properties of the camera …
