Visual search in clutter
Detecting a target in clutter is particularly difficult because the observer must monitor many potential locations to find the target, and because the clutter itself might mask the target. To investigate whether contemporary models of search can account for visual search in clutter, we measured the detection of an oblique string of five aligned dots presented at an unknown location as a functio...
متن کاملVisual Search Asymmetries in Heavy Clutter: Implications for Display Design
OBJECTIVE An experiment aimed to test whether design of symbology to produce visual search asymmetries might facilitate target detection in cluttered displays. BACKGROUND A visual search asymmetry exists between two stimuli when a target of one type is found efficiently among distractors of the second type but a target of the second type is found with difficulty among distractors of the first...
متن کاملMeasuring visual clutter.
Visual clutter concerns designers of user interfaces and information visualizations. This should not surprise visual perception researchers because excess and/or disorganized display items can cause crowding, masking, decreased recognition performance due to occlusion, greater difficulty at both segmenting a scene and performing visual search, and so on. Given a reliable measure of the visual c...
متن کاملSearch for a category target in clutter.
An airport security worker searching a suitcase for a weapon is engaging in an especially difficult search task: the target is not well-specified, it is not salient, and it is not predicted by its context. Under these conditions, search may proceed item-by-item. In the experiment reported here we tested whether the items for this form of search are whole familiar objects. Our displays were comp...
متن کاملVisual Clutter Causes High-Magnitude Errors
Perceptual decisions are often made in cluttered environments, where a target may be confounded with competing "distractor" stimuli. Although many studies and theoretical treatments have highlighted the effect of distractors on performance, it remains unclear how they affect the quality of perceptual decisions. Here we show that perceptual clutter leads not only to an increase in judgment error...
