SEE-THROUGH WALLS CREATE ROOM WITH A VIEW
Susumu Tachi, the inventor of an "invisibility" cloak that seems to disappear by projecting onto its surface an image of what's behind it, says his next project will be see-through walls that can provide interior office dwellers a room with a view. "This technology can be used in all kinds of ways, but I wanted to create a vision of invisibility. My short-term goal would be, for example, to make a room that has no outside windows appear to have a view to the outside, then the wall would appear to be invisible," says Tachi. He uses a computer-generated image projected onto a surface of "retro-reflectum" material that provides the illusion of a three-dimensional vision. "The material is the key to our technology," says Tachi, who adds that he's been working on the concept for the last 25 years. "It didn't work at all when we just projected the image onto a normal screen. We tried hard, but it took awhile before we came up with this retro-reflective material."
