EyeMusic is a set of glasses that have a camera and headphones developed by The Hebrew University of Jerusalem. The camera scans the viewpoint for images, and translates those images into music for the blind. According to medGadget:
EyeMusic is a sensory substitution device (SSD) that converts visual input into audio output, and many have been attempted before… The trick for making a good SSD is in finding a mapping from visuals to sound that makes it easy to interpret what one is hearing.
For EyeMusic, each color is given a corresponding musical instrument; it also leverages musical scales to convey visual data. The device will hopefully be able to be used to help the blind perform tasks like shopping at the grocery store.
