Operator distraction level

Abstract

A method, apparatus, and computer program product are provided for calculating an indicator of operator distraction for an equipment operator. First, distraction-correlated indicator information from devices around an operator is received. Next, a distraction level is estimated. Subsequently, an output is produced indicative of the distraction level to facilitate a threat assessment decision. Additional operations may include grouping information into complex task types comprising sets of related activities. Next, an elapsed time is determined since the start of the first activity in a complex task. The delay since the most recent activity in the complex task is compared with a minimum task quiescent period. When the delay exceeds the minimum task quiescent period, the elapsed time and the delay are reset. Also, during the performance of a complex task, the type and the elapsed time of the complex task are correlated with other information to facilitate a threat assessment decision.
