Technology that generates touchable 3D imagery was unveiled in Japan Monday, with its developers saying users could pull and push objects that are not really there. Touching is an important part of human communication but virtual reality has until now been lacking it, its chief executive Natsuo Koda told a press conference. This technology will give you a sense that you can touch objects in the 3D world, said Koda, a former Sony researcher on virtual reality. It works by fooling the brain, blending the images the eye is seeing with different patterns of vibration created by a small device on the fingertip, said Norio Nakamura, the inventor of 3D-Haptics Technology and chief technical officer at the firm.
