Uncertainty sets associated with saccadic eye movements-basis of satisfaction control.

Abstract Two types of uncertainty sets associated with visual target aquisition are described; one associated with the target's presentation time and another associated with the distance of the target's image from the fovea. The characteristics of the uncertainty sets are discussed in terms of anatomical and electrophysiological data. Also discussed are the relationships between the uncertainty sets and multiple saccades. Furthermore, it is argued that these sets form the basis for the “satisfaction” control action (versus optimization) of the saccadic system.
