SAN FRANCISCO — Meta Platforms said it has updated the Ray-Ban Meta smart glasses with AI video capability and real-time language translation functionality. The latest update adds video to Meta’s AI chatbot assistant, which allows the Ray-Ban smart glasses to process what the user is seeing and respond to questions in real-time. The smart glasses will now be able to translate speech in real time between English and Spanish, French or Italian. Meta also added Shazam, an app that lets users identify songs, to the smart glasses, which will be available in the US and Canada. In September, Meta said it is updating the Ray-Ban smart glasses with several new AI features, including tools for setting reminders and the ability to scan QR codes and phone numbers using voice commands.
