Out-of-the-loop performance problem

The out-of-the-loop performance problem (OOL or OOTL^[1]) arises when an operator suffers from performance decrement as a consequence of automation.^[2]^[3] The potential loss of skills and of situation awareness caused by vigilance and complacency problems might make operators of automated systems unable to operate manually in case of system failure.^[4] Highly automated systems reduce the operator to monitoring role, which diminishes the chances for the operator to understand the system.^[5] It is related to mind wandering.^[5]
