We can think of our eyes as though they’re video cameras that record information about the world so that we can better interact with it. However, our visual system outperforms any commercially available video camera. Think about how every movement of a handheld video recording device corresponds to a “shake” of the recorded image making it frustrating to watch. Now consider that every second we’re awake we make “saccadic” eye movements that shift the image on our retinas faster than anyone could move a camera through space. In contrast to the recorded videos filmed by “shaky cam”, our conscious perception of the visual world is high resolution with very little visible smear or blur. One of the primary purposes of my research is to examine some of the ways in which the human visual system achieves this apparently stable representation of the visual world. More generally, I’m interested in how moving our eyes affects our basic visual perception.
