A Model of Eye Movements and Visual Attention
نویسنده
چکیده
This paper introduces the EMMA model of eye movements and visual attention. EMMA provides a formal model of the temporal and spatial aspects of eye movements as they arise from shifts in visual attention. To implement the model, EMMA is integrated into the ACT-R/PM cognitive architecture (Anderson & Lebiere, 1998) and requires minimal modification of existing ACT-R/PM models. This paper details the EMMA model, theory, and implementation and also demonstrates how the extended framework helps to capture important aspects of behavior in an equation-solving task.

Application of eye tracking technology for screening and rehabilitation of children with special needs.
Eye tracking is a technology for measuring eye movements when looking at a point. The length of time to look at a particular situation, the sequence of observations, as well as points of attention are processed in the process of eye tracking and eye movements are identified by topics such as fixation, saccade, etc. Information about how the eyes move at a special moment has many potential appli...
متن کاملVisual attention to the Logos of Popular and Unknown Brands: An Eye-tracking Study during Decision-making
A logo epitomizes a brand and depicts the picture of a product; consequently, attention, as an initial step of the AIDA model, to the logo is a good-looking index to survey the cognitive processing during consumers’ decision-making. Eye tracker extracts the visual attention data. For these reasons and appreciated from fixation duration, in the present study, the process of visual attention to t...

متن کاملAn integrated model of eye movements and visual encoding
Recent computational models of cognition have made good progress in accounting for the visual processes needed to encode external stimuli. However, these models typically incorporate simplified models of visual processing that assume a constant encoding time for all visual objects and do not distinguish between eye movements and shifts of attention. This paper presents a domain-independent comp...
متن کاملJust Noticeable Difference Estimation Using Visual Saliency in Images
Due to some physiological and physical limitations in the brain and the eye, the human visual system (HVS) is unable to perceive some changes in the visual signal whose range is lower than a certain threshold so-called just-noticeable distortion (JND) threshold. Visual attention (VA) provides a mechanism for selection of particular aspects of a visual scene so as to reduce the computational loa...
