Rohildev N., 23, from Kerela has developed a device called Fin, a tiny hardware that one can wear on one’s thumb as a ring and which converts the whole palm into a gesture interface. Fin has been created at Rohildev’s RHL Vision Technologies at the Startup Village in Kochi. 

Wearable devices are the next stage of computing and the thumb ring developed by Rohil and his team is stylish and easy to use. Fin, worn as a ring on your thumb, has sensors that can uniquely recognize each segment (phalange) of the fingers and identify various parts of the palm by calculating their distance from the thumb. So you can assign different functions to each finger segment, and can perform a function by making your thumb touch the relevant segment. This means that the simple touch of your thumb on a finger segment can send an emergency alert, silence your phone, move to the next track on your playlist, or pick up a call – all without you actually touching the device.

It uses smart low energy technology such as Bluetooth for communication with connected devices. Fin, according to a report in the Indian Science Journal (ISJ) website, can transmit natural gestures as commands to any connected Bluetooth device, such as a smartphone, a music player, a gaming console, a digital interface inside a car, a television set or a home automation device. 

According to Rohildev, if you have home automation devices, your palm can operate those without raising a hand or any gestures, unlike other touchless technologies. 

Made out of durable, waterproof and dustproof material, a single Fin will be capable of supporting up to three devices at a time. It will come with a custom Lithium ion battery with micro-USB charging dock and last more than one month on full charge.

Fin will be priced at $120 each, but that cost could come down with mass manufacturing. Read more
