Summary
This study tests a wearable device that uses directional sound to help people with low vision detect obstacles. Fifty participants with normal vision will wear a blindfold and walk a path with obstacles, once with the device and once without. The device emits tones that get louder as the person gets closer to an object, potentially improving safety and mobility.
