Good news, awkward fanboys! Japanese scientists are working around the clock to make digital ads interactive enough that you can make out with them. Keidai Ogawa, a researcher at Keio University who is obsessed with his country's pop idols, has outfitted digital posters of them with ultrasound sensors that change the image to a kissy-kissy face as you approach. He's also working on getting the displays to recognize "the scent of shampoo on the hair [and] lemon-flavored film on the lip regions." How to make any of this even halfway acceptable in public is, of course, a problem all its own—the ramifications of this technology are both undignified and unsanitary. After all, who wants to catch mouth herpes from a Nicki Minaj poster in the DC Metro? Via PSFK.
