What’s the one piece of advice you’ve heard time and time again about any type of public speaking? Yes, the most common thing you’ll hear is “just imagine every one in the audience in their underwear.”
So, now that there’s Google Glass, why not build the app that lets the presenter envision everyone in their underwear. Of course, this is just for public speaking training purposes. Maybe it’s even as simple as a projection of a previously recorded audience that you practice on where everyone’s already agreed to be filmed in their underwear.
If nothing else, it would prove out whether or not this is actually good advice.
