As a kid I was obsessed with the idea of Smell-O-Vision, the scent dispersing system invented in the 1950s and used in movie theaters to give people a more tactile viewing experience—it allowed them to smell what was going on in the movie. Alas, it never quite took off, and despite furtive attempts here and there to revive it over the years, Smell-O-Vision remains an idea whose time has yet to come. Or does it...? Leave it to Japan to find a way to combine scent and technology! From Popular Science comes word of Chat Perf, a fragrance atomizer for your iPhone. It’s a little tank filled with a scent that attaches to the dock, and claims to allow you to “send smells across cyberspace” with the tap of a touchscreen.
