Partitioning Visual Displays: Directing the Path of Visual Search
We reduced time to detect target symbols in mock radar screens by partitioning displays in accordance with task instructions. Targets appeared among distractor symbols either close to or far from the display center, and participants were instructed to find the target closest to the center. Search time increased with both number of distractors and distance of target from center, and the effect o...
متن کاملSaccadic selectivity in complex visual search displays
Visual search is a fundamental and routine task of everyday life. Studying visual search promises to shed light on the basic attentional mechanisms that facilitate visual processing. To investigate visual attention during search processes, numerous studies measured the selectivity of observers' saccadic eye movements for local display features. These experiments almost entirely relied on simple...
متن کاملPartitioning Visual Displays Aids Task-Directed Visual Search
We reduced time to detect target symbols in mock radar screens by adding perceptual boundaries that partitioned displays in accordance with task instructions. Targets appeared among distractor symbols either close to or far from the display center, and participants were instructed to find the target closest to the center. Search time increased with both number of distractors and distance of tar...
متن کاملCognitive Strategies for the Visual Search of Hierarchical Computer Displays
This article investigates the cognitive strategies that people use to search computer displays. Several different visual layouts are examined: unlabeled layouts that contain multiple groups of items but no group headings, labeled layouts in which items are grouped and each group has a useful heading, and a target-only layout that contains just one item. A number of plausible strategies were pro...
متن کاملGaze Contingent Displays: Analysis of Saccadic Plasticity in Visual Search
Gaze contingent displays were used to simulate visual field loss during performance of visual search tasks. Comparison of human saccadic strategies with those of a Bayesian ideal searcher show that humans rapidly adapt their saccadic strategies, but that this learning is limited and depends on the spatial pattern of vision loss.
