The creators of this piece Benjamin Burns and Fernando Orellana used recorded brain activity during REM sleep to determine the robots behavior and movements. Its like “play back” for human dreams. I thought that it is quite amazing how we can use robots to help us read our subconsciousness. The idea behind Sleep Walking is to make the viewer consider the brain not only as a center of human activity but as a site for interpretation. It also shows us how much technology has affected our lives and how contemporary artists use scientific knowledge to be innovative.
