Using to Sound to Help the Visually Impaired

"Sensory substitution devices (SSDs) use sound or touch to help the visually impaired perceive the visual scene surrounding them," according to Medical News Today. "The ideal SSD would assist not only in sensing the environment but also in performing daily activities based on this input. For example, accurately reaching for a coffee cup, or shaking a friend's hand. In a new study, scientists trained blindfolded sighted participants to perform fast and accurate movements using a new SSD, called EyeMusic. Their results are published in the July issue of Restorative Neurology and Neuroscience.  The EyeMusic, developed by a team of researchers at the Hebrew University of Jerusalem, employs pleasant musical tones and scales to help the visually impaired 'see' using music. This non-invasive SSD converts images into a combination of musical notes, or 'soundscapes.'"Read more.
