It might look like another fitness band, but this is actually the world's first wearable air guitar. AirJamz promises to turn air guitar into wear guitar by strapping to your wrist, and making guitar sounds as you strum away, Digital Spy said.

It's made by the same people who made Jamstik+, which was basically a Guitar Hero controller without the game to help you learn the guitar. AirJamz makes no such promise - you won't learn chord progressions or key changes, but you will be able to pretend you're an axe star, Digital Spy said.

Inside is an accelerometer that responds to how you move it. Fire up the app on your smartphone, pick a song from one of those offered, and you have to move the AirJamz in time to keep the guitar playing.

You can also use it to trigger sound effects, and you can add other players and jam along together.
