Automation surprises result from an imbalance between ‘autonomy’ and ‘authority’ of advanced automated systems and the gaps in the operator’s mental model of the system and its interactions. The vital factor at play in such cases could be low observability interfaces in novel (“nonroutine elements”) situations with operator caught in a bind while trying to …
