This program converts live camera images into auditory signals allowing blind and visually impaired people to use their auditory sense to acquire information that their visual sense would normally have provided to them. A very modular software design has been chosen to enable other users and researchers to add easily new sensory mappings and even user interfaces. A novel sensory substitution mapping has been developed introducing for the first time binaural cues to such a prosthesis, enabling users to perform object segregation in complex scenes using their natural auditory scene analysis skills.
