A team at Georgia Tech and Atlanta's Shepherd Center invented a vibrating glove that buzzes certain fingers when a piano song is played.
Basically a person wears the glove and gets to feel what finger they should be using to play a song.
The researchers found that people who used the glove actually really improved their motor skills as well as learning the piano more easily.
We can think of a thousand more uses for a vibrating glove. LOLz!
Check out the video (above) to see the glove in action.
