Official title
Neurobehavioral Effects of Visual Assistive Technologies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical investigation is to learn how the brain responds when visual information is converted into patterns of sound or touch in blind and sighted participants. The main questions it aims to answer are: * Does converting visual information into sound or touch patterns change visual performance in the blind or blindfolded? * How does the brain adapt to different kinds of sensory information? Researchers will use brain imaging and simple performance tasks to see how people process and learn from this type of converted sensory input. The investigators will compare how individuals with and without long-term vision loss respond to these signals. Participants will: * Learn to use technologies to assist in visual information conversion into sound or touch patterns every day for 5 weeks; * Visit the brain imaging center 3 times for brain scans and behavioral tests.
