Apple wins patent on glasses-free 3D projector

angry tapir writes: "Apple has been awarded a U.S. patent for a display system that would allow multiple viewers to see a high-quality 3D image projected on a screen without the need for special glasses, regardless of where they are sitting. Entertainment is far from the only field in which 3D can enhance the viewing experience: others include medical diagnostics, flight simulation, air traffic control, battlefield simulation, weather diagnostics, advertising and education, according to Apple's U.S. patent 7,843,449 for a 3D display system."
