I like the idea to fix the part about you looking stupid waving your hands around why not have like a toggle for privacy you can make it so other people cant see and for displaying things and presenting you could set it so anyone wearing the glasses could see. You could also invite people to a "group" so you and your friends would be the only ones displaying things. It would be cool for it to display your friend in front of you talking to you as a hologram or creepy...
