Fin has made a Bluetooth ring that can function as a wireless controller for different connected devices. The Palo Alto-based company has reached its $100,000 crowdfunding target on Indiegogo. Now, the firm wants to stretch its goal to $150,000 to make way for discounted price of the said product to visually impaired users, according to TechCrunch.

The Bluetooth ring is worn on the thumb. Movement is detected and commands are sent to connected to gadgets using an optical sensor that can be swiped or tapped. According to Greg Kumparak of TechCrunch, users can control phone volume and playlist with a swipe of the thumb, the report explained.

RHL Vision, the maker of the Fin ring, wants to develop a future biometrics system for the device to assign a specific control to every segment of the finger, the report added.

Aside from possessing the cool factor, Fin is also a useful gadget for those with motor or visual impairments. RHL Vision said the device has the potential to help over 285 million visually impaired people have an easier interaction with technology. If the company hits its stretch goal, the said product will have a special price of $59 for the blind people, TechCrunch reported.
