Fin: Rohildev Nattukallingal’s device controls smartphones & TV remote through your palm

Well, get ready for the next wave of people acting strange publicly, gesturing and waving their fingers in your face, with colourful rings around their thumbs. Because they're coming, and those rings are the newest addition to the "internet of things" — wearable technology that promises to change the world. The rings, called Fins, make your entire palm a gesture interface with which you can control multiple connected devices.

Wearable technology is the new cool and everyone knows about Google glasses and Pebble watches. But an Indian innovator may beat all the rest by being the first to actually launch his wearable device, the Fin, a tiny piece of hardware that you can wear on your thumb, which is capable of recognizing each segment of your finger biometrically and converts your palm into a numeric keypad. Why, if Rohildev Nattukallingal and

his team have their way, you may never need to touch your phone again to make a call! Or a television remote or any home automation device. It's the world at your fingertips — literally.Fin reads different gestures from your palm and its corresponding values control connected devices. So, for example, if you want to turn your phone's volume down, all you need to do is swipe your thumb down your index finger. Want to turn it back up? Just swipe back up across the same finger. Want to skip the current track? Swipe your thumb across the palm of the opposite hand. You get the general idea.
Another really interesting thing about this innovation is the manner in which Nattukallingal found funding. His RHL Vision is one of the rare Indian companies that have used crowdfunding, using the Indiegogo platform. Crowdfunding is the collective effort of individuals who network and pool their money, usually via the internet, to support efforts initiated by other people or organizations.
