Sound of Vision (Natural sense of vision through acoustics and haptics) will design, implement and validate an original non-invasive, wearable hardware and software system to assist visually impaired people by creating and conveying an auditory representation of the surrounding environment. This representation will be created, updated and delivered to the blind users continuously and in real time. In addition to the auditory representation, haptics will be used moderately as an additional channel to convey some of the most relevant information. The system will help visually impaired people to both perceive and navigate in any kind of environment (indoor/outdoor), without the need for predefined tags/sensors located in the surroundings and regardless of the lighting conditions.
