A small proportion of the population cannot see color, instead they view the world as mono-chromatic (shades of grey). One such individual is Neil Harbisson, who was born in Barcelona, Spain.
As reported in The Telegraph
, when he was in his 20's, Harbisson had a fortuitous meeting with a cyberneticist called Adam Montandon, (who was based at the University of Plymouth, UK). When Harbisson described the way he saw the world the two of them decided to undertake a technological experiment designed to help Harbisson to perceive colors.
After considering different options, Montandon was inspired by the physical similarities of light and sound. From this Montadon and Harbisson created a device modelled on a computer webcam which translated the light waves that correspond to different colors into sounds with different pitches. They dubbed the device, according to The Sun
, the "eyeborg".
By practicing with the device, Harbisson learnt several color/pitch associations. According to The Scientist
, Harbisson can hear colors of wavelengths not visible to the human eye, such as those in the infrared.
From this pioneering work, Harbisson's has gone to create a series of short films and videoart works based on the relationship between colour and sound and the relationship between humans and colour.
Here is one of them:
