Japanese Technology Makes Craziest Invisibility Cloak Yet (VIDEO)
Huffingtonpost.com reports that the cloak is made using Retro-reflective Projection Technology, a process that superimposes the virtual world onto the real world. They call it creating an ‘Augmented Reality.’ So actually, the cloak is not invisible per se, but rather made of lots of tiny beads that reflect light only in the direction they came from.
A camera in the cloak takes in the scene behind the wearer. Then, according to Creator’s Project: “A computer processes the background imagery and relays it to a projector that filters through a half mirror and projects the scene onto the wearer. From a certain angle, the cloaked person looks transparent to onlookers.”
