3D display cube creates images in real-time |
3D display cube creates images in real-timeJapan’s National Institute of Information and Communications Technology has unveiled a new handheld, 3D communications tool. The gCubik, developed by the NICT earlier in the year, reproduces 3D images, inside a 10cm-per-side cube, that are viewable without special glasses. Now, the gCubik+i can generate the images in real-time allowing them to be manipulated using touchscreen panels and on-board motion sensors. All the six faces of the cube display 3D images, allowing users to see the display from every possible direction. By adding special sensors, users can also interact with the inside images.
Technical explanation from NICTEach face of the display uses integral photography, which is one of the various methods to display 3D images without special glasses (auto-stereoscopic). When viewing a real scene, humans see a different image with each eye, which depends on the distance and the different position of the eyes (binocular parallax). When we move our heads, we see different images (motion parallax). These are some of clues on how humans perceive depth (3D). Integral photography uses a tightly packed micro convex lens array to record distinct 'elemental' images, and when these images are again viewed through the same micro-lens array, they reproduce the 3D integrated image of the scene with both binocular and motion parallax. The Institute’s system utilises the electronic integral photography which uses an LCD display, instead of the recorded photograph, to display the elemental images.
