| More optical illusions were offered up by a 3D wide-screen display called Holovizio, which creates giant images resembling holograms. But instead of using lasers, 64 digital projectors are arranged behind the screen, and are programmed to illuminate it together, in order to build up the 3D image. The effect works across a broader range of angles than a conventional hologram, allowing several people to view it at once. A hand-tracking system also lets viewers interact with the display, turning the image upside down or back-to-front. |
