Augmented reality is catching some huge buzz, but one of the problems with virtual worlds is you can see and hear them, but you can’t feel them.

The University of Tokyo is working on a solution to that.  Using motion sensors and highly-tuned compressed air, the system simulates the sensation of touch as a user, say, bounces a ball, or touches a surface.

Bonus points for the use of Wii remotes about a minute in.
