Impact of automated decision aids on performance, operator behaviour and workload in a simulated supervisory control task

摘要: In studies reporting automation effects on overall system performance and the operator, methods used to measure workload often did not appropriately reflect complexity of this construct. The present study addresses impact operator behaviour in process control fault management. Workload were assessed with subjective, cardiovascular secondary task indicators. Interactions interface simulation directed at gathering information controlling recorded. Automation made operators more efficient, allowing faster management less sampling actions. Subjective ratings significantly lower assisted conditions as compared manual, which was reflected measures. Participants' activity differ between medium high level automation. Results suggest that participants paid constantly attention their even highly automated support.
