Last month, the US Patent Office announced a patent for the smart ring that Microsoft is applying for. Wearable devices have always been a hot field of intelligent hardware, and many large companies have also set foot in it, including Microsoft. At present, Microsoft has launched the second generation of the Microsoft Band, but it has no special advantages over other smart bracelets in terms of functions.

The latest patent of Microsoft shows that they will develop a new smart ring. The smart ring has a built-in curved sensor that can recognize the swing of finger joints. One of the killer applications of the smart ring is that after the smart ring is connected to the computer, the user can wear two or more rings to realize the left/right click function of the mouse through the swing of the finger joints (the finger movement when tapping the mouse). Its appearance will have an impact on the existing peripheral market, especially the wireless mouse market. In addition, the industry insiders said that the smart ring has more functions than this, and it also includes some bracelet functions, such as footnotes, sleep, and so on.
