A nonlinear estimation problem motivated by attentive vision in the human visual system is considered. In human vision, eye and head motion are used to bring objects of interest into the high resolution foveal regions of the retina. Accurate estimates of target position are thereby attained in certain target tracking situations using sensors (eyes) having nonuniform and mostly low acuity. This preliminary study considers a target tracking problem involving a sensor having a movable a high acuity 'foveal' region surrounded by a low acuity peripheral region. This example demonstrates how an attentive tracking strategy allows a sensor with a small foveal region to significantly outperform a sensor with uniformly low acuity.
