Sometime at parties I wish for a HUD that would show me people's name and the last time I saw them. On the other hand I dislike wearing glasses at social events, since I don't really need them.

I really don't look forward to trying to politely explain why I don't like having my face uploaded into the facial recognition/person-tracking system that will involve.

I do look forward to our cyberpunk future where to "opt out" of certain systems, you have to paint a certain mark on your face, or put a little QRCode sticker on your cheek.

"Sorry, I'm only opted into Google Facemind and FacebookFace; I don't want to be indexed by Amazon Visage."

People have begun studying makeup and hair styles that foil today's face recognition in general: https://cvdazzle.com/

Or wear a government issue spook "ugly t-shirt".

Could be local only. New faces are saved as they're detected. Then later on your computer, add notes to the new faces ("John Smith, met 11/7/19 at Liz's party, programmer at Initech").

When those faces are re-detected, show the info text.

Would certainly be nice if you could do a similar thing without needing a camera on the glasses at all though. How can we recognize a person reliably without seeing them? Maybe by their voice?

I agree. Of course such system have some pretty important downsides. I'll perhaps have to pay more attention to people then.

Parties in Virtual Worlds are great in this regard, since you can see not only someone's name but also their IM address, profile and sometimes notes you've made about them in the past. So I know I'd appreciate it in RL.

That would be great for people with face blindness.
