University of Tokyo Unveils Airborne Ultrasound Tactile Display.

Over the years we have seen prototypes for projectors turning skin into touch interfaces. The latest is a product called Airborne Ultrasound Tactile Display that was developed by the University of Tokyo. The system is rather bulky right now and consists of a projector, PC, and several fans to create “tactile sensations.” This means that the fans create pressure on the user’s skin, similar to the rumble feature of a game controller. The system can create interactive displays as well as video. It uses motion tracking as well so that the image displays on the hand at all times. Unfortunately there is no information about further development.
