Fin is a Bluetooth-enabled wearable ring that allows the user to control devices with hand gestures. It reads gestures from the palm and uses those values to control connected devices like music systems, TVs, cameras, and more. The ring costs around Rs. 7400 and works using low-energy Bluetooth and sensors that detect gestures and convert them into signals to command different technologies. Funds raised will be used to further develop the ring's capabilities, improve authentication, design production, and integrate additional platforms and devices.
