Meta Chief Product Officer Chris Cox said on Thursday that smart glasses are the future of computing devices. "We talk to them, we will see with them, we will use gestures the same way we interact with each other to interact with our computers," Cox told CNBC's Julia Boorstin. "The interfaces will get more natural, and so we certainly believe that the next really important wearable technology is going to be a pair of glasses." The $799 Meta Ray-Ban Display glasses, which were revealed on Wednesday, have a small in-lens display that is controlled with hand movements using a neural wristband. Users will be able to record videos, as well as send messages via voice or physically using handwriting gestures on their knee, Cox said.
