Semantic guidance of eye movements during real-world scene inspection
This is the first study to measure semantic guidance during scene inspection, based on the efforts by two other research groups, namely the development of the LabelMe objectannotated image database and the LSA@CU text/word latent semantic analysis tool, which computes the conceptual distance between two terms. Our analysis reveals the existence of semantic guidance during scene inspection, that...
متن کاملThe Role of Top-down and Bottom-up Processes in Guiding Eye Movements during Visual Search
To investigate how top-down (TD) and bottom-up (BU) information is weighted in the guidance of human search behavior, we manipulated the proportions of BU and TD components in a saliency-based model. The model is biologically plausible and implements an artificial retina and a neuronal population code. The BU component is based on feature-contrast. The TD component is defined by a feature-templ...
متن کاملThe influence of clutter on real-world scene search: evidence from search efficiency and eye movements.
We investigated the relationship between visual clutter and visual search in real-world scenes. Specifically, we investigated whether visual clutter, indexed by feature congestion, sub-band entropy, and edge density, correlates with search performance as assessed both by traditional behavioral measures (response time and error rate) and by eye movements. Our results demonstrate that clutter is ...
متن کاملTop-down guidance of eye movements in conjunction search
We provide novel evidence for a two-stage model of visual search applied to the selection based on top-down cues to stimulus colour and orientation. The model supposes that visual displays are first parsed into colour based groups, a process that is modulated by the presence of an initial cue to the target's colour. Subsequently search is directed to other featural properties represented within...
متن کاملScene context guides eye movements during visual search
How does scene context guide search behavior to likely target locations? We had observers search for scene-constrained and scene-unconstrained targets, and found that scene-constrained targets were detected faster and with fewer eye movements. Observers also directed more initial saccades to target-consistent scene regions and devoted more time to searching these regions. However, final checkin...
