Israeli scientists invent visor that resurrects vision

 
22 february 2012

Science fiction is becoming reality, thanks to an Israeli team of scientists and their device that allows the blind to see.

 

Dr Amir Amedi of the Hebrew University of Jerusalem has demonstrated a visor that can use sound to hack into the visual cortex of blind people which allows them to see.

 

The Sensory Substitution Device, invented over 20 years ago by Dutch researcher Dr Peter Meijer, uses an algorithm to translate the position and appearance of an object into distinct tones.

 

The discovery builds on previous work by the team which showed braille readers show activity in precisely the same part of the brain that lights up when sighted readers read.
