Visual Availability and Fixation Memory in Modeling Visual Search using the EPIC Architecture
نویسندگان
چکیده
A set of eye movement data from a visual search task using realistically complex and numerous stimuli was modeled with the EPIC architecture, which provides direct support for oculomotor constraints and visual availability constraints due to retinal non-homogeneity. The results show how the quantitative details of visual search can be explained within an architectural framework, and have useful practical, methodological, and theoretical implications.

The persistent visual store as the locus of fixation memory in visual search tasks
Experiments on visual search have demonstrated the existence of a relatively large and reliable memory for which objects have been fixated; an indication of this memory is that revisits (fixations on previously fixated objects) typically comprise only about 5% of fixations. Any cognitive architecture that supports visual search must account for where such memory resides in the system and how it...
متن کاملModeling Visual Search of Displays of Many Objects: The Role of Differential Acuity and Fixation Memory
This paper describes a classic data set on visual search of 100-object displays that differ in size, shape, and color and presents a cognitive architecture model based on the active vision concept that accounts for the effects using differential visual acuity and fixation memory provided by a persistent visual store. The results provide an approximate upper bound on the duration of fixation mem...
متن کاملExplaining Eye Movements in the Visual Search of Varying Density Layouts
This research advances computational cognitive modeling of visual search, and the synergistic relationship between cognitive modeling and eye tracking. The paper presents cognitive models of the perceptual, cognitive, and motor processing involved in the visual search of words in structured layouts that vary in density. The layouts are allsparse, all-dense, or mixed. A principled approach is ta...
متن کاملIdentification of the underlying factors affecting information seeking behavior of users interacting with the visual search option in EBSCO: a grounded theory study
Background and Aim: Information seeking is interactive behavior of searcher with information systems and this active interaction occurs in a real environment known as background or context. This study investigated the factors influencing the formation of layers of context and their impact on the interaction of the user with search option dialoge in EBSCO database. Method: Data from 28 semi-stru...
متن کاملApplication of Architectural Visual Documents and Oral History of in the Representation of Micro-Spaces and Three-Dimensional (3D) Modeling of Nawab Razavi Historical House in Yazd
Over the time, various factors have led to damage the Iranian houses. By examining the surviving documents of Nawab Razavichr('39')s house in Yazd, it is possible to represent a major part of the lost spaces and also to minimize speculation in the restoration of this historic house. The basic belief of this research is that the studies of the oral history of architecture as well as the existing...
