So, how does the whole thing play out? Users download the free iOS app "oSnap", photograph their meals, and tag it with the appropriate smells – in the future, the last step will be automatic. The so-called "oNote" is sent over e-mail, Facebook, and Twitter to "oPhone hotspots" around the world. As the technology is a showroom piece for now, these are positioned only in Manhattan, Paris, and Cambridge, so plan your trip accordingly.
Vapor wants to launch the oPhone as early as 2015, so it put together an Indiegogo campaign. If the fundraiser goes as planned, the device will sell for $199 ($149 on pre-sale). Edwards admits that the first oPhone will be "more of a massive focus group" than the done deal, but if the technology works smooth enough, users should be pretty enthusiastic to the idea. And when the whole thing gets shrunk to fit modern smartphones, app creators' imagination will be on fire. "Illustrating" a photo with an authentic scent will deliver a bold impact. In the professor's own words, “I say to you 'croissant', and you say ‘Oh, that sounds good,’ but you smell it and you’re hungry.”
