Can Fin Smart Ring Win Where Others Have Failed?

A Kochi-based company is working on Fin, a bluetooth smart ring, that will let you use gestures on your palm to control your smartphone, TV, car stereo or any other connected device. RHL Vision, the company behind the concept has started a campaign in Indiegogo to raise which funds which the company needs to take the concept to the market.

The ring that needs to be worn on your thumb can be swiped on various parts of your hand o control various devices around you. It uses sensors that can uniquely identify each part of your hand to achieve this. There have been several pitches for smart rings made before such as NFC Ring or SmartyRing being developed by a Chennai-based company, but Fin stands out with its capability to use smart gestures to actually control devices as opposed to acting as a notification centre on your ring.

The company, that is incubated in Startup Village, had showcased the concept at Techcrunch Hardware Battlefield, but that was a prototype with the circuit still attached to a small board instead of inside the ring. The company is now in the process of finalising its flexible PCB design that will accommodate all the sensors, components and battery within the casing of the ring. It’s worth noting that the company is developing their own designs rather than using off-the-shelf designs from Chinese manufacturers.

Most of these smart rings use Bluetooth Low Energy (BLE) or NFC to connect to devices around, but Fin will use Bluetooth dual-mode for compatibility with more devices. The advantage of using BLE is that devices will have very low power consumption, but in case of dual mode it might be slightly higher. The company claims that the battery should last for about a week after charging, but since it hasn’t disclosed the capacity of the battery it will be using in its final product, we’ll need to wait and see if the company can deliver on that front.


RHL Vision started working on this concept eight months back and developed the first prototype three months back. In the next stage they will integrate an optical sensor that will be able to uniquely identify which part of the palm you’re touching and assign each segment of your fingers to a particular device. As of now the optical sensor can detect the gestures and use it control one device. Using gestures one can change tracks, increase or decrease volume, answer calls as of now.

The company is trying to raise $100,000 via Indiegogo but has managed to raise only $6,157 till now. The ring is being offered for $99 via the fundraising website, with a note that the device will cost $120 when it’s commercially available. Rohildev N, the founder of the company however is still going ahead with the project. He is planning to visit China next month to speed up the manufacturing process. As of now, they are building the PCBs in India and assembling them in Kochi on their own.

Rohildev says that they are not just about hardware. The software they have developed is what does a lot of the heavy-lifting. The company has also built custom apps that Fin users can install in their phones and tablets for better user experience.
