Microsoft filed for a patent for a Smart Ring

According to Microsoft, the smart ring can act as a universal input device that will work with TVs, desktop computers, laptops, smart phones, tablets and even other wearable devices like glasses, wrist bands, and watches.

The smart ring includes a flexion sensor to detect a pose of the finger. This enables the smart ring to interpret movement of the finger and the fingertip.

The smart ring wirelessly transmits information related to the pose and movement of the finger to control any companion device. Thereby, the smart ring allows a user to use her finger to control the companion device.

It will be a big relief if a single device can be used to control all devices.
