Fin Gesture Control Ring
There are many unique types of gesture control devices out there, but this one is slightly different. The device ‘transforms’ your palm into a gesture interface, so you’ve essentially got a keypad or touchpad, right on your hand. This is made possible by the fact that the tiny device is programmed to recognize each segment of your fingers. The current version of Fin can carry up to five different commands per device, but its creators might be aiming for more in the final version. It connects to most smart devices via bluetooth. Also it will come with a powerful built-in battery that can last for more than a month.
Fin is currently up for funding on Indiegogo, where $80 will get you one of your own.
