Screenshot: USTPO One thing that most Big Tech companies working on smart glasses haven’t figure out yet is how to effectively interact with an augmented reality environment. Apple is heavily rumored to be working on its own pair of AR glasses and apparently considered vibrating haptic socks to tackle this problem.
