Everybody around you will have no idea why you're stroking your own arm in a creepy fashion, but it will be totally worth it.

The smartwatch is a marvellous invention, but let’s be honest – that screen is far too tiny for the grand ambitions we have for it. Thankfully for us a team at the Carnegie Mellon University has been doing some out of the box thinking. Or to be more accurate…out of the smartwatch thinking (we’ll just leave).

A project spawned from the Human-Computer Interaction Institute’s Future Interfaces Group, SkinTrack is a two-part device that transforms your skin into an extension of your minuscule smartwatch screen. With the electrode-packed strap fixed onto your smartwatch and a mini finger sensor in place, you can swipe, tap and type to your heart’s content on your forearm or hand like a cyborg of the future.

SkinTrack mirrors your finger gestures on your smartwatch screen with 99 percent accuracy, which is down to the low-energy, high-frequency signal sent through the skin whenever the finger touches or comes close to its surface. This makes it easy as pie to dial a number on a keypad, tap out a quick message, doodle, zoom, swipe and tap your apps, and most importantly, fling an angry bird into the air at the perfect angle…

Achieve the angry bird accuracy you always dreamed of with SkinTrack’s nigh on perfect tracking abilities.

The interesting thing about SkinTrack is that, unlike a lot of the adventurous tech prototypes we come across, there don’t seem to be many limitations or caveats. It’s discreet, it blends in with your existing wrist kit, and it works seamlessly with most of the commands that you use on a daily basis. It’s even equipped to deal with hot key commands; you can trace an N on your hand to open your news app, or draw an S to silence an incoming call that you want to ignore.

The only thing you’ll have to get used to is wearing the sensor ring, but if the team can get it comfortable and looking just like a normal ring you’d wear on your finger, that’s our one quibble bopped on the head.
