 Title: Towards Active Vision in the DUAL Cognitive Architecture Authors: Nestor, AdrianKokinov, Boicho Keywords: Active VisionCognitive ArchitectureEye MovementsStructural DescriptionsVisual Attention Issue Date: 2004 Publisher: Institute of Information Theories and Applications FOI ITHEA Abstract: The paper describes an extension of the cognitive architecture DUAL with a model of visual attention and perception. The goal of this attempt is to account for the construction and the categorization of object and scene representations derived from visual stimuli in the TextWorld microdomain. Low-level parallel computations are combined with an active serial deployment of visual attention enabling the construction of abstract symbolic representations. A limited-capacity short-term visual store holding information across attention shifts forms the core of the model interfacing between the low-level representation of the stimulus and DUAL’s semantic memory. The model is validated by comparing the results of a simulation with real data from an eye movement experiment with human subjects.
