The Stranger Than Fiction World of Sensory Substitution

Sensory substitution refers to the idea of feeding information into the brain via unusual sensory channels. It's just what we've inherited from a complex road of evolution but that particular collection of sensors might not have to be what we stick with. For example, what if you took a data stream from a video camera and converted that into touch on your skin with the brain eventually being able to interpret the visual world simply by feeling it? The first paper demonstrating this was published in the journal Nature in 1969.
