In human vision, acuity and color sensitivity are best at
the point of fixation, and the visual-cognitive system
exploits this fact by actively controlling gaze to direct
fixation towards important and informative scene
regions in real time as needed. How gaze control operates
over complex real-world scenes has recently
become of central concern in several core cognitive
science disciplines including cognitive psychology,
visual neuroscience, and machine vision. This article
reviews current approaches and empirical findings in
human gaze control during real-world scene perception
