One of the strongest limits of visual perception is 'crowding' - the inability to identify objects in clutter that are easily identified in isolation. For example, a letter presented in the visual periphery, that is easily identified when presented alone, is harder to identify when flanked by other letters. Crowding fundamentally limits numerous tasks such as reading, visual search, and object recognition. In this research program, we use a combination of psychophysics, computational methods, and newly developed appearance-based methods to characterize crowding phenomenology, create simulations of peripheral appearance, and devise methods to alleviate crowding and increase reading performance. We investigate crowding in observer populations that differ in regard to crowding strength, such as normal readers and dyslexics, and closely collaborate with visual artists to shed light on visual appearance, crowding, and the underlying mechanisms of spatial vision.
