This is actually pretty cool!

But what about people with arthritis or similar afflictions? Might pose a challenge. But the technology itself is really cool.

That's very cool. I'd love something like this coupled with an AR lens to display the results in front of my eyes.

What crossed my mind though is a real air guitar.
