An Intelligent Threat Assessment Tool for Decluttering Naval Air Defense Displays
Abstract
Operational displays can quickly become congested with large numbers of symbols. This report discusses our study of a naval air defense task in which users monitored a cluttered airspace, evaluated aircraft for their levels of threat, and executed defensive responses against significant threats. A heuristic threat assessment algorithm continuously evaluated aircraft for their levels of threat, and it "decluttered" the less threatening ones by decreasing the salience of their symbols on the geographical display. As expected, 27 expert U.S. Navy users appropriately distrusted the automation and continuously checked its assessments. Nonetheless, decluttering improved response timeliness to threatening aircraft by 25% compared with a baseline display with no decluttering, and it was especially beneficial for detecting and monitoring threats in more peripheral locations on the display. Decluttering did not affect which aircraft were deemed threatening, and 25 out of 27 users preferred using a declutter display over the baseline display.
