Meta glasses were used by the New Orleans attacker. Here’s what they do

CNN — The attacker who drove a truck through New Orleans’ Bourbon Street on New Year’s Day used Meta smart glasses to scout the scene weeks earlier, according to the FBI. By saying, “Hey Meta,” which is the device’s “wake word,” users can tell the glasses to begin recording. Meta’s website explains the glasses won’t react if “we detect speech not intended for your glasses” and, if someone is using another feature that uses the microphone, the glasses “will not be listening for your follow-up request.” Users can turn on voice storage and, if there are “misactivations” — in which the user didn’t intend to trigger voice controls — recordings and transcripts will be deleted “within 90 days of detection.” The glasses have a built-in speaker on the frames that plays music, AI and phone audio. Don’t use your glasses to engage in harmful activities like harassment, infringing on privacy rights, or capturing sensitive information like pin codes.” The glasses have two lights: an inward-facing LED to notify users that capture, voice control and call may be in use and an outward-facing capture LED to let others know when the glasses are turning on and taking photo or video.
