The man who drove a truck into a crowd of people in New Orleans on New Years Day, killing 14, had previously scouted the French Quarter and recorded video with his Meta smart glasses, the FBI said.On Oct. 31, Shamsud-Din Jabbar recorded video with the glasses as he cycled through the French Quarter and plotted the attack, said Lyonel Myrthil, FBI special agent in charge of the New Orleans field office. Jabbar also wore the glasses, which are capable of livestreaming, during the attack, but did not activate them.A spokesperson for Meta, the parent company of Facebook, declined to comment.Heres what the glasses are capable of:What are Meta glasses?Meta glasses, made in partnership with Ray-Ban, are frames with a built-in camera, speakers, and artificial intelligence that can be controlled with your voice, buttons, and some simple gestures. Some functions, such as listening to music or interacting with Metas AI assistant, require the device to be either paired with a phone or able to access the internet.The wearable does not have a display built into the lens, unlike some past industry attempts at building augmented-reality smart glasses. However, Meta has said it is working on a pair of glasses that will give users a fully holographic experience.What the glasses can doOne of the glasses main selling points is the ability to capture images and video using the onboard camera, then upload those files to Instagram or Facebook. You can also livestream, but only to Metas compatible social platforms.You can also use the glasses to make audio and video calls, message people, or listen to music.The camera also allows Metas AI assistant to see what youre seeing, allowing it to translate text into multiple languages (spoken back to you, or shown on a paired phone app), and answer simple questions, such as searching the nearest landmark to your location. The glasses are largely a hands-free experience so you will be talking to your deviceand it will reply.What the glasses cant doThe glasses currently cannot perform complex tasks that other digital assistants might be able to, like booking you a reservation at a restaurant or giving you turn-by-turn directions while youre on the move. And theres no display in the lens, so there isnt a viewfinder for framing photos or video.There are also visual indicators built into the system that allow bystanders to know when youre shooting video or taking photos. This LED privacy indicator stays on while you use the camera functions. According to Meta, you cant disable this light to be more discreet in your actions.
