The Fraunhofer institute, University of Kiel and RealEyes is showing a new technology that enables 3D posters for large outdoors advertisements (up to 5 meters) and these do not require any glasses.The researchers say that the display are similar to the lenticular images we've seen on postcards but instead of the grooved sheet with the image attached, the new posters use a lens array - 250,000 lenses and each 2 millimeters in diameter. The 3D image of the poster can be viewed from the other side of the street, and the image appearance changes with each step and adjusts to the visual angle.They have already built a DIN-A0 (1 sq meter) poster prototype, and they say that commercialization of larger posters (3 to 5 sq meters) is possible in coming 2011http://feedproxy.google.com/~r/TechnologySky/~3/wuY1xxg0ihA/new-3d-poster-technology-coming-soon.html
