Kerala startup develops Fin, a ring-shaped wearable that brings the 'touchscreen' to your palm

A new gesture-based wearable transmitter that turns your palm into a touch interface has been developed by a Kerala-based IT startup. The ring-shaped transmitter called Fin is worn on the thumb and uses Bluetooth to communicate with different devices. The portable device enables users to control up to three devices such as smartphones, car radios and smart TVs using only swipes and taps.   “People in today’s world are becoming more busy, but still they are wasting a lot of time interacting with their smart devices,” Rohildev Nattukallingal, founder of the Kochi-based RHLVision Technologies, the startup behind Fin. “Fin removes this interaction gap by allowing users to quickly interact with those devices,” said Nattukallingal.   Until now, the device has five pre-programmed gestures. However, users will be able to create customised programmes on an app that will come with the device, in its final iteration. The device can control the volume on a TV, and even lets users text or dial a number without touching their phone. The developers say they hope Fin can help people who are visually impaired.   Fin is not the only ring-based wearable being developed in India. Chennai-based Smarty Ring project used IndieGogo to get its project off the ground. This lets you control your smartphone with just a small ring on your finger, and brings dedicated music controls to your fingers. The campaign, which was seeking $40,000 through IndieGogo ended up raising close to $300,000 from the campaign. You can read more about the Smarty Ring **here.**   With inputs from PTI
