An important aspect of computer-controlled camera motion systems is that of the generation of saccadic movements, which shift the camera gaze quickly from one fixation position to another. Recent psychophysical experiments suggest that there exists a causal connection between spatial shifts in visual attention and the production of saccadic eye movements in humans. Motivated by this experimental evidence, we propose a winner-take-all based model of exogenous spatial attention, involving both sustained and transient feature detection channels, and link it to the targetting and triggering of saccadic eye movements. We show that this model accounts for a range of oculomotor phenomena observed in human subjects. We describe the application of this model to a robotic camera gaze control system
