https://www.cnet.com/news/google-may-be-working-on-a-standalone-ar-headset/ > Site Winfuture.de claims to have documents about a project codenamed Google A65, thought to be a standalone AR headset. > The documents indicate Google's working with a Taiwanese manufacturer, Quanta, which Google's worked with before on the Pixel C tablet. It's expected to include camera sensors and microphones; the latter aren't common on the VR and mixed-reality headsets out today. Chances are the mics are there for voice operation via Google Assistant.
