Abstract

Viewer’s eye movements and behavioural responses were analysed in order to determine the relationship between selective perception and visual attention during a dual detection task in the central and peripheral fields of vision, in order to design a better functioning information display. Changes in visual attention levels were evaluated using the temporal frequency of microsaccades. Accurate rates of stimulus detection response and microsaccade frequency were estimated using a hierarchical Bayesian model. In the results, the dominance of the response in the peripheral field of vision is confirmed. Also, chronological changes in levels of attention and the contribution of these changes to behavioural responses were examined. The relationship between behavioural responses, micorsaccade frequency, and the directional dominance of certain viewing areas in the peripheral field of vision were discussed, in order to evaluate the level of visual attention of viewers.
