By precisely detecting its location across your palm and fingers, Fin can be used to send a number of differing commands to up to three separate connected devices. Control your smart TV, smartphone, car audio or even your gaming console with simple gestures. Current versions of the Fin can handle up to five different gestures per device, but those are developer units. The final version will hopefully be capable of much more. They're even being tinkered with to work as controllers for Oculus Rift, Google Glass and other headsets.
