First of all, I must begin with the disclaimer that Google Nose Beta does not actually work, however convincing it might appear to be. This new online feature is a clever fabrication that is, albeit, quite enticing.
A Google link and an accompanying YouTube video describe how this early version of the aromatic application integrates a 'smell' button within your search results. Clicking on this would allow you to inhale and experience places and objects through a sense that has so far been excluded from computer usage.
Spokesmen assert that the extensive mobile aroma indexing program has 15 million scentibytes from all over the world. They explain that "by intersecting photons with infrasound waves, Google Nose Beta temporarily aligns molecules to emulate a particular scent." All you'd have to do is sniff in the vicinity of your screen.
