Modeling Visual Search of Displays of Many Objects: The Role of Differential Acuity and Fixation Memory
نویسنده
چکیده
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 memory, and some approximate acuity functions for modeling visual search.

متن کاملThe 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 cognitive effects on visual search for targets in cluttered backgrounds
To understand how a human operator performs visual search in complex scenes, it is necessary to take into account top-down cognitive biases in addition to bottom-up visual saliency effects. We constructed a model to elucidate the relationship between saliency and cognitive effects in the domain of visual search for distant targets in photo-realistic images of cluttered scenes. In this domain, d...
