I would like to disagree that there aren't any moving parts used whilst generating ultrasonic waves. After all, something needs to vibrate. Ultrasonic levitation is pretty cool, and the tacile interface isn't bad either. I just somewhat pity that they've looked at the technology and told themselves "Ohh, that'd be great for musicians", which I think isn't the right assumption to make in this case. I mean HD-MIDI still hasn't been adapted widely after being discussed in 2005 (that's 8 years now), so I wonder if musicians are a fertile breeding ground for "paradigm changing tacile interfaces".
