A lot of virtual reality, quite simply, isn't. It replicates the visuals and sounds, but not much else. Tokyo Metropolitan University's Ikei Laboratory is taking a shot at filling in more of the experience with a new exhibition. Its virtual body seat goes beyond a 3D screen and headphones to include vibrating foot pedals, for recreating the ground, as well as a fan that both produces wind and wafts scents. The demonstrator is currently being used to impress guests with the scents of a Milanese market or the rush of an Usain Bolt sprint, but it could eventually serve a practical purpose for some of the population: TMU sees its chair replacing an environment for those who can't be there in person. About all that's missing is taste, although we don't really need to lick our virtual worlds. Yet.
