Guest Speaker @SCIoI: Martina Poletti - Active Foveal Vision

“Active Foveal Vision” by Martina Poletti (University of Rochester) Martina Poletti’s talk focusses on active foveal vision. Vision is an active process even at its finest scale in the 1-deg foveola, the visual system is primarily sensitive to changes in the visual input and it has been shown that fixational eye movements reformat the spatiotemporal flow to the retina in a way that is optimal for fine spatial vision. Using high-precision eye-tracking coupled with a system for gaze-contingent display capable of localizing the line of sight with arcminute precision, and an Adaptive Optics Scanning Light Ophthalmoscope (AOSLO) for high-resolution retinal imaging enabling retinal-contingent manipulations of the visual input, their results show that the need for active foveolar vision also stems from the non-uniformity of fine spatial vision across this region. Further, they show that the visual system is highly sensitive even to a small sub-foveolar loss of vision and fixation behavior is readjusted to compensate for this loss. Overall, the emerging picture is that of a highly non-homogenous foveolar vision characterized by a refined level of control of attention and fixational eye movements at this scale. This talk was part of Olga Shurygina‘s course “Active Sensing,” a seminar on cutting-edge research on active sensory perception in humans and other mammals and realted advances in artificial agents’ abilities such as seeing, grasping, and navigating in space. --- Science of Intelligence is a Berlin-based, DFG-funded Cluster of Excellence with the central scientific objective to collect and apply all principles of intelligence in order to create intelligent technology in an ethically responsible way.
