Research output: Contribution to journalConference articlepeer-review


A simulation task for circuit-board inspection was designed with different image patterns to analyze inspectors' search strategies including the scan-path and the stopping policy. This study focused on how people fixate and locate defects, and the subsequent decision making processes. According to Gestalt laws of organization, a complex searching field would be decomposed in groups for separate scans. The analysis of scan-path shows that subjects had their own respective search pattern for all trials. Although the scan-paths were found different, search behavior within image patterns were similar across subjects. It implies that the visual search is driven by image patterns.
