PROGRAM

Image Quality: Perception & Adaptation, Ray Applegate, Session Chair

While image quality metrics are well understood for optical systems with low aberrations, they generally fail to apply for the high aberrations found in the eye. An understanding of optical image quality in the eye is important for many applications, ranging from measurements of the outcomes of refractive surgery to building a better autorefractor.

Low Vision Devices & Applications, Robert Massof, Session Chair

As computing power becomes cheaper and more miniaturized it has become easier to provide the visually impaired with sophisticated low vision devices.

Contributed Color Session, Barry Lee, Session Chair

Contributed papers to this session were handled by the Color Committee Chairs

Innovations in Eyetracking, Mary Hayhoe, Session Chair

Recent advances in eyetracking technology and methodologies have opened new areas of research. The advent of high-speed imaging systems allows real-time tracking at rates equal to or greater than that possible with analog and opto-mechanical systems. Ever-increasing processing power in desktop and embedded processors presents new opportunities to implement complex algorithms that were computationally prohibitive in the past. The miniaturization of electronics has also played a role; systems that until recently were restricted to use in the laboratory have now been reduced in bulk and power consumption to the extent that real-time, wearable eyetrackers are practical. This workshop will review these advances and focus on results from research made possible by those advances.

Non-classical Spectral Inputs to Visual Pathways, Joel Pokorny, Session Chair

This symposium will present findings on recently discovered photosensitive ganglion cells as well as several other novel cellular inputs to visual pathways.

Visual Plasticity in "Normal" Vision, Manfred Fahle, Session Chair

There is increasing interest in examining how the human visual system adapts as a function of experience throughout life. This symposium will explore the site and mechanisms underlying this plasticity.

Models of Color Appearance, Kathy Mullen, Session Chair

This symposium will present advances in color theory from computational, psychophysical, and applied perspectives.

Visual Plasticity and Rehabilitation, Krystel Huxlin, Session Chair

Even though it is known that visual training can improve performance in the visually impaired, little is known about the mechanisms underlying this improvement. This makes it difficult for clinicians to identify patients whose performance might be improved with rehabilitative training, and means that there is very little consensus on what sorts of training would be most useful for patients. This workshop and discussion will focus on: What is the best strategy to rehabilitate vision in humans after damage—molding the visual world to the abnormal brain or molding the brain to the visual world? What are the limits to visual system plasticity?

Time Scales and Significance of Adaptation, Qasim Zaidi, Session Chair

This symposium will present recent data on mechanisms of adaptation with very short time scales and those with unusually long time scales. We ask, to what extent can time scales help us to infer the locus of adaptation in the visual pathways, and do the unusual time scales provide new insight into the function of adaptation?

Contributed Vision Session, Ione Fine, Session Chair

Contributed papers to this session were handled by the Vision Committee Chairs

Physiology of Cortical Adaptation, Alex Wade, Session Chair

The fields of psychophysics, neurophysiology, and fMRI all examine adaptation or use it as a tool. Are they really all studying the same thing? If so, what do the results across these three disciplines tell us about the mechanisms of adaptation?
