Michael Proulx, a neuroscientist at Queen Mary’s College in London, will be demonstrating the device, know as “vOICe,” at the American Psychological Association meeting this week in Washington.
vOICe works by mapping visual images to sound and then providing blindfolded users with a sense of what an object is and where it is located.
