VR headsets are usually quite smart. For better or for worse - and I personally think it's very much for the better - many AR glasses are a DisplayPort monitor that you wear on your face. They have inertial sensors and speakers, but the interface to the PC is Displayport-over-USBC for video to the glasses, USB Audio Class for the speakers, and usually a proprietary USB peripheral for the inertial measurements. Some AR glasses attempt to require being paired with a dedicated video phone-like device, largely to attempt to extract subscription revenue. Most do not. It's perfectly possible to drive a pair of AR glasses from an Android smartphone, a video-game-focused SBC, or a miniPC. Anything with DisplayPort video out at 1080p or better (3840x1080 if you want 3D videos).
