We've told you about touch-sensitive floors before, but this one really kicks it up a notch - as in playing a CGI soccer game on its surface.
Developed by Patrick Baudisch and his colleagues at Hasso Plattner Institute in Potsdam, Germany, this glass, 26-square foot pressure-sensing "smart floor," called GravitySpace, recognizes people by their weight and tracks their whereabouts to display interactive videos.
Walking on the floor is akin to walking over a mirror where one's computer-generated doppelganger is digitally reflected. The idea is that the pressure-sensing technology could turn your floor into an interactive surface that controls electronics in your homes, lets you play games and monitors elderly or disabled people.
For example, if you walked into the room, the floor could recognize your weight and play your favorite album, turn on you favorite TV channel or just turn on the lights. Or you could call up a game of virtual soccer and perhaps save a few lamps from getting broken.
As of now GravitySpace exists only as a prototype that relies on a sub-level space below the two-and-a-half-inch-thick glass floor where an infrared camera tracks footprints and a high-resolution video projector transmits video up onto the glass.
