Here’s a smart new approach to helping the totally blind. Rather than try to repair a damaged sense, why not reroute data through one that’s still all-systems-go? The ‘vOICe’ system uses a glasses-mounted camera to examine the user’s field of vision, and then translates the data into sound. After a little practice, this synaesthesic way of seeing can apparently become second nature, with the information being perceived visually despite being made up of audio.
