You’ve probably played air guitar to your favorite tune. If you are more cultivated, you’re maybe more into air violins. Or air harps. Or air pianos. Now you can do just that: Play an airpiano.
Airpiano has 8 infrared sensors that acts as keys. They measure the distance from the keyboard to your hand. Each sensor has three different tones depending on how high you raise your hand, totaling 24 different notes. You simply play the Airpiano by waving your hand over the keyboard – no physical contact is needed.
