Presentation Effects and Eye-Motion Behaviors in Dynamic Visual Inspection
研究了传送带速度和物体间距对动态视觉检查表现及眼动行为的影响，发现检查错误与视觉行为高度相关。
Dynamic visual inspection (DVI) occurs when objects on a moving conveyor are being individually examined for compliance with specifications. This study investigated the effect of the conveyor velocity and object interspacing on DVI performance and eye-motion behavior during this task. Nine combinations of these object presentation factors were examined where three pairs of these combinations each had a constant throughput rate (or exposure time). Horizontal eye-motion measurements were made through electrooculography recordings, and these measurements were analyzed to separately distinguish the visual acquisition time from the visual tracking time. Both of these time values tended to vary predictably with the available exposure time and consistently between people as a visual behavior strategy. Inspection errors were found to be highly correlated with the visual behavior.
