Remember the days of being completely freaked out by the people out in public who appeared to be caring on a very animated and usually very loud conversation with themselves? Only moments later to discover a small new device called a Bluetooth Headset behind their ear just before you thought they were crazy? Then again when Google Glass was released, a whole new generation of people waving their hands in the air and talking to themselves was born again. Well get ready for the next set of people waving their hands around in the air, thanks to a new wearable, gesture based gadget called Fin. The Fin is a wearable Bluetooth device that turns your hand into a “numeric keypad and gesture space”. Small movements can be programmed to control your smartphone, TV, games console, camera – pretty much anything. The Huffington Post reports ” The Fin could also have more profound applications such as helping the visually impaired.” Currently the Fin is being funded on Indiegogo and has raised $23,000 (£14,100) of a $100,000 (£61,400) total. The Fin has set the bar high for its competitors and is rapidly making a big name for itself. It has already been featured in Yahoo, The Discovery Channel, AOL, and Gizmag.
