In a darkened room in the back of a small furniture store just south of San Francisco International Airport, the couch in front of me keeps changing colors and patterns, from red to blue to beige to a gray, white, and green pattern.The couch is real — I can reach out and poke the cushions — but the psychedelic surface-shifting effect is created with augmented reality technology that projects fabric patterns onto the surface of the couch (which in reality is a boring shade of gray).via http://mashable.com/2014/08/28/augmented-reality-furniture/
