Apple is continuing to develop, refine, and expand its concept of a finger-worn, smart ring that could be used to wirelessly control nearby devices, or interface with an augmented reality peripheral like the rumored “Apple Glass.”
The company first applied for, and was granted, a smart ring patent back in 2015. Since then, Apple has applied for a steady series of continuation patents for a range of smart ring features and functionality.
In a new patent application published by the U.S. patent and Trademark Office on Thursday, Apple refined the concept of the smart ring. Mostly, it appears to have broadened the language it’s using.
