National Institute of Advanced Industrial Science and Technology of Japan (AIST) announced iCubeSpace, a system which enabled an operator to feel and touch to control a virtual obstacle on 3D display panel. According to the spokes person on the TV news, possible application areas will be ranging from TV gaming, training for surgical operations to virtually touching an art object displayed in an famous museum. The press release is only in Japanese so far. In the meantime, a DigInfoTV picked up the news at CEDEC 2010 held in Yokohama last week. The TV news available on YouTube is here although it's only in Japanese, too.
