Here, we studied how heuristic automation can aid users by intelligently \"decluttering\" the display. In a realistic simulated naval air defense task, 27 experienced U.S. Navy users monitored a cluttered airspace and executed defensive responses against significant threats. An algorithm continuously evaluated aircraft for their levels of threat and decluttered the less threatening ones by dimming their symbols. Users appropriately distrusted and spot--checked the automation's assessments, and decluttering had very little effect on which aircraft were judged as significantly threatening. Nonetheless, decluttering improved the timeliness of responses to threatening aircraft by 25% as compared with a baseline display with no decluttering; it was especially beneficial for threats in more peripheral locations, and 25 of 27 participants preferred decluttering. Heuristic automation, when properly designed to guide users' attention by decluttering less important objects, may prove valuable in many cluttered monitoring situations, including air traffic management, crisis team management, and tactical situation awareness in general.<\/jats:p>","DOI":"10.1518\/001872005774860014","type":"journal-article","created":{"date-parts":[[2005,11,19]],"date-time":"2005-11-19T17:54:55Z","timestamp":1132422895000},"page":"509-525","source":"Crossref","is-referenced-by-count":46,"title":["Heuristic Automation for Decluttering Tactical Displays"],"prefix":"10.1177","volume":"47","author":[{"given":"Mark","family":"St. John","sequence":"first","affiliation":[{"name":"Pacific Science & Engineering Group, San Diego, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harvey S.","family":"Smallman","sequence":"additional","affiliation":[{"name":"Pacific Science & Engineering Group, San Diego, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel I.","family":"Manes","sequence":"additional","affiliation":[{"name":"Pacific Science & Engineering Group, San Diego, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bela A.","family":"Feher","sequence":"additional","affiliation":[{"name":"Space and Naval Warfare System Center, San Diego, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey G.","family":"Morrison","sequence":"additional","affiliation":[{"name":"Space and Naval Warfare System Center, San Diego, California"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2005,9,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2044-8295.1972.tb01304.x"},{"key":"atypb2","volume-title":"Department of defense, interface standard, common warfighting symbology","author":"Department of Defense.","year":"1999"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1177\/001872088903100206"},{"key":"atypb4","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1016\/S0166-4115(08)62386-9","volume-title":"Human mental workload","author":"Hart, S.
