    Acoustic Cues for Wayfinding

    This project aims to do a detailed analysis of the environmental acoustic cues that help some blind navigate successfully.

    Learning in the Sighted and the Blind through Different Sensory Modalities: Structure and Dynamics of Cortical Reorganization

    This project focuses on the emerging area of the neuroscience of art learning. It addresses the important issue of how the brain learns complex skills, specifically the process of drawing, through two different sensory modalities.

    Human Oculomotor Functions & Their Deficits in Traumatic Brain Injury

    Recent studies have established that a high proportion of patients diagnosed with mild (or diffuse) traumatic brain injury (mTBI) exhibit binocular vision dysfunctions, particularly, deficiencies in the binocular coordination of eye movements.

    Encoding of 3D Structure in the Visual Scene: A New Conceptualization

    The multidisciplinary goal was to develop an integrated conceptualization of the mid-level encoding of 3D object structure from multiple surface cues

  • Completed

    Stereoscopic motion-in-depth perception: fMRI and neurophysiological studies

    This project is designed to advance the integration of high field fMRI in alert macaque monkeys with "informed" neurophysiology, and to apply it in addressing a long-standing research question regarding the neural processing of stereoscopic 3-D motion.

    Advanced Spatiomotor Rehabilitation in Blindness and Visual Impairment

    We propose a multidisciplinary approach to effective spatiomotor rehabilitation in blindness and visual impairment. For those who have lost vision, the eye-hand coordination normally available for the manipulation of objects for everyday activities is unavailable and has to be replaced by information from other senses

    Upper Depth Limit Across Visual Field

    Stereopsis is important for tasks of daily living such as eye-hand coordination. It is best in central vision but is also mediated by the periphery. Previously we have shown that individuals with central-field loss who have residual stereopsis in the periphery perform better at an eye-hand-coordination task. Here we sought to determine what sets the limit of stereopsis, defined as the largest disparity that supports the sustained appearance of depth, in the near periphery in healthy individuals.

    Motion Perception in Central Field Loss

    The project investigates motion perception in individuals with vision loss due to central retinal lesion, but who retain healthy peripheral retina. Healthy peripheral retina is exquisitely sensitive to fast speeds, however, there is limited and conflicting information about motion processing in residual peripheral retina in patients with central field loss, often due to macular degeneration. We use psychophysical and eye tracking approaches to systematically probe speed and direction sensitivity in this  population.

    The Smith-Kettlewell Haptics Symposium

    The Smith-Kettlewell Haptics Symposium was held on March 29, 2018 to honor and remember Dr. Val Morash and her research.

    Regressions in Braille Reading

    This project explores regressions (movements to re-read text) in braille reading.

    The image on the right plots the braille reading finger movements in blue and regressions in black.

    Calibration of Eccentric Power Refractor

    Eccentric power refractors need to be calibrated for accommodation and gaze position for individual participants. Calibration however can be time consuming. We look at different conditions in which calibration is necessary or preferable.

    The Window of Spatial Attention in Reading

    We investigate the dynamics of spatial attention while the eyes move around to gather information.
