So by putting advertising in the restroom on a mirror will make people want to buy say water, tickets, etc etc. The purpose of mindshare, as I see it, is that when someone thinks of bottled water, for instance, you think of maybe a handful of brands like Aquafina, Deer Park, Dasani, etc etc. So by advertising on a smart mirror, even though the display will be off in the corner, just out of direct eyesight, the object will be in your immediate thoughts for you to want to buy.
It's scary, but smart. Thanks for the heads up! And I'll be able to apply this to my major in college as well.
