摘要

The potential for change detection failure during the monitoring of a military digital situation awareness map was investigated. Participants were asked to monitor the map for icon appearance or disappearance. A change accompanied by two other changes was detected 69.3% of the time, while the same change occurring alone was detected 79.6% of the time. When three changes occurred simultaneously, all three were detected only 37% of the time. Detection of icon appearance was superior to detection of icon disappearance, as might be expected from the literature on visual attention. The discussion addresses the need to represent change explicitly in such systems and suggests properties that a change detection aid should possess.
