Sensory substitution devices (SSDs) are non-invasive sensory aids that provide visual information to the blind via their existing senses. For example, a visual-to-auditory SSD translates images into sounds, retaining the visual shape information. In my PhD work with Amir Amedi, we developed a unique program for teaching blind people how to use the vOICe (an SSD developed by Peter Meijer) to learn to see information captured by a miniature webcam that they carried on their sunglasses.
