Disney uses puffs of air for haptic feedback.

by Brad Hayes

The good folks over at Walt Disney Imagineering have come up with a new an interesting way to create the sensation of contact with virtual objects. This little device creates small puffs of air that simulate the sensation of touch. It you have ever played with an air puff gun, you know that this kind of thing can travel fairly long distances and still have a significant effect. 

I would love to see this replace the air jets on the Indiana Jones ride. Those seem to just be blast of compressed air. and they make a ton of noise.
