Several benefits even for people in one’s address book:
- Remind one of someone’s name in case one has forgotten (especially for those with face blindness).
- Remind one of last phone call or meeting date (again just in case one has forgotten).
- Remind one of the person’s spouse’s name, bf name, gf name, kids name, etc.
- Log that you saw them so you can ”remember” for your next conversation.
People with assistants already have this “functionality” and this would democratize this.
It would depend on how they worked. AR glasses that did local recognition and did not record video without an specific action and indicator (like that on the Snap Spectacles) would be fine with me. Something that streamed the video feed to Google or Facebook? Not going to happen for me.
