Influence of local scene color on fixation position in visual search.
Where observers concentrate their gaze during visual search depends on several factors. The aim here was to determine how much of the variance in observers' fixations in natural scenes can be explained by local scene color and how that variance is related to viewing bias. Fixation data were taken from an experiment in which observers searched images of 20 natural rural and urban scenes for a sm...
متن کاملInfluence of initial fixation position in scene viewing.
During scene perception our eyes generate complex sequences of fixations. Predictors of fixation locations are bottom-up factors such as luminance contrast, top-down factors like viewing instruction, and systematic biases, e.g., the tendency to place fixations near the center of an image. However, comparatively little is known about the dynamics of scanpaths after experimental manipulation of s...
متن کاملInfluence of scene-based properties on visual search.
The task of visual search is to determine as rapidly as possible whether a target item is present or absent in a display. Rapidly detected items are thought to contain features that correspond to primitive elements in the human visual system. In previous theories, it has been assumed that visual search is based on simple two-dimensional features in the image. However, visual search also has acc...
متن کاملInfluence of scene structure and content on visual search strategies.
When searching for a target within an image, our brain can adopt different strategies, but which one does it choose? This question can be answered by tracking the motion of the eye while it executes the task. Following many individuals performing various search tasks, we distinguish between two competing strategies. Motivated by these findings, we introduce a model that captures the interplay o...
متن کاملThe Influence of Local Density and Link Color on Visual Search
Visual search in an important part of human-computer interaction (HCI) research ( Byrne, 1993; Czerwinski, Tan, & Robertson, 2002; Jacob & Karn, 2003). It is through visual search that most people locate the content and controls for many computer tasks. Yet, it is not well understood how visual search is applied with the use of computers for a great many visual tasks. HCI needs a good, unified ...
