Rows and rows of solenoids on the back of the chair take imagery from a video camera and produce impulse patterns on the sitter’s back. The brain then interprets the patterns back into imagery. Personally, I think the polypropylene "canteen" chair made for MoMA is more stylish. [Dezeen]

Take one polypropylene chair from either the canteen or the stationery cupboard. Place electronic unit that shows video imagery as dynamic pixelated physical information and transmits it to the sitter via the skin on his or her back. Plug in. Turn on. Like I said, Wowzers.

Developed back in the Sixties by a guy called Paul Bach-Y-Rita, sensory substitution allows one sensory modality to be developed used by another. The most common method is using the sensation of touch to allow the brain to see images and is used in brain function studies, cognition and rehabilitation.

The Mind Chair is a collaboration between artists Paul Marigold and Beta Tank and will be on show at the MoMA in New York as part of the Design and the Electric Mind exhibition, from February 24 to May 22. Something tells me there'll be a queue to sit on that particular chair. [Dezeen]
