Facebook glasses: Not overly ‘smart,’ maybe a little shady

The company’s answer, in a way, was to prevent smart glasses from acting too smart. In the case of the Facebook voice assistant, the company insists it listens only for the “Hey, Facebook” wake phrase. And even then, there are only three things you can request after that: Take a photo, record a video and stop recording. Facebook will almost certainly teach its Siri rival new tricks soon enough, but turning off those listening features entirely is plenty simple and probably a good idea.
