A new wearable, gesture-based device from RHL Vision Technologies literally puts the control in the palm of your hand. Or rather, on your hand.

Fin is a smart ring prototype that is worn around the thumb, allowing users to turn their palm into a digital controller. Fin incorporates an optical sensor that is able to detect swipes and taps on your hand, matching the desired action to an assigned function. Connected to the device you’ve selected – smartphone, smart TV, etc. – Fin detects the gesture and sends the corresponding command (i.e. changing the song on your phone).

Users will be able to control up to three devices with a single Fin, including smartphones, smart TVs, automobile electronics, and home automation platforms. Communicating via Bluetooth, the aim is to eventually incorporate biometrics into Fin that would allow the device to distinguish between each segment of each finger to make swiping and tapping even easier. Essentially, Fin will turn each part of your hand into a different button.


Rohildev Nattukallingal, founder of RHL Vision Technologies – the startup launching Fin – described Fin’s purpose to Mashable.

People in today’s world are becoming more busy, but still they are wasting a lot of time interacting with their smart devices….Fin removes this interaction gap by allowing users to quickly interact with those devices.

The current vision for Fin will provide for five pre-programmed gestures, but the creators already have plans for a software kit that will allow developers to create custom ones for related apps. Due to its ease of use and tactile nature, Fin is also anticipated to help the visually impaired interact with technology.


Fin will be available in five different colors and will retail for $120 upon its expected release in September 2014. The project is using the popular crowdfunding site Indiegogo to raise funds, and have already far surpassed their goal. With a stated funding aim of $100,000, Fin has raised over $150,000 with nearly two weeks of funding left.
