The moving eye: a model for the 21st century sensor?

Biology offers suggestive models for the control of active sensors. Two natural conceptions are compared to data on eye movements-pervasive integration models, which propose that information about eye movements is integrated into central representations, and peripheral translation models which assume that visual data is translated out of eye-based co-ordinates at an early stage. There are major problems with both. A better summary is that the visual system represents the world in multiple ways, and different representations have different access routes to the moving sensor system.
