    Assessment of Speechreading with Dual Sensory Loss: Visual and Hearing Impairments

    The purpose of this research study is to test subjects who have various hearing and vision problems on their lipreading, visual and auditory skills in order to understand the relationships between lipreading and visual impairment.

    Micro-Perimetry by Scanning Laser Ophthalmoscope

    We developed software to make the retinal placement of stimuli during micro-perimetry by a scanning laser ophthalmoscope (SLO) independent of involuntary fixational eye movements.

    Motion as a Cue for Attention

    We investigated whether relative motion can serve as a cue for sustained attention.

  • Completed

    Focal Attention and Letter Recognition

    We studied letter recognition in 8 deg eccentricity from the fovea after attracting sustained focal attention to the stimulated location by a cue. Young and elderly healthy subjects, as well as patients with central vision loss participated.

  • Completed

    Reading with the Retinal Periphery

    Typographical features of letters were manipulated in such a way that frequently occurring letter confusions in eccentric viewing happened less frequently.

  • Completed

    Dyslexia Project

    We studied the ability of dyslexic young teenagers to fluently name pictograms (shapes of objects). We found that some dyslexics are very good at this task, some were even better than the control subjects.

    Hearing Aid for Blind Travelers with Hearing Loss

    Blind travelers rely on subtle acoustic cues for independent mobility. When hearing becomes impaired, as in the normal aging process, a special type of hearing aid may be needed to enhance these cues.

    Tactile map featuring braille and low-vision bolded text for a six block radius. Streets and intersections are raised and labeled for use by blind, and viewers with low vision.

    Tactile Map Automated Production (TMAP)

    Smith-Kettlewell's Tactile Map Automated Production (TMAP) Project was initiated with the goal of developing the first web-based software tool for rapid production of highly specific, tactile street maps of any location in the USA.

    Audio/Tactile Graphics Using LiveScribe Smartpen

    Active from 2007 to 2010, this project was the first exploration of using a digital smartpen as a platform for creating and presenting audio/tactile graphics – a system of using touch-based audio to annotate tactile figures to improve access to graphical information for the blind.

    Crowd-Sourced Description for Web-Based Video (CSD)

    The Descriptive Video Exchange Project focuses on crowd-sourced techniques for describing DVD media.

  • Completed

    Algorithmic Automated Description (AAD)

    Automated algorithmic description (AAD) uses existing machine-vision techniques to automate specific aspects of description such as camera motion, scene changes, face identification, and the reading of printed text. Such events could be identified by computer routines that automatically add annotations to the video.

    Novel Method to Teach Scotoma Awareness

    This project aims to improve visual function in individuals with age-related macular degeneration (AMD). AMD isassociated with central field loss that cannot be corrected optically.
