This is a most excellent place for technology news and articles.
I think you hit the nail with 'no camera'. Honestly, a camera isn't needed... if you want a picture, use your phone. If you want a POV image or video, use a Go Pro.
Smart glasses should be a display only (well, maybe speakers too).
It's also possible to have a camera but explicitly no persistent recording built into the hardware design. purely ephemeral video analysis for whatever UI/HUD data you want.
