Ah, those zany Keio University researchers trying to recreate Smell-O-Vision, do you want to know what they're up to these days? They're still trying, of course, but now they've taken the opportunity to demonstrate their hardware -- which uses basic inkjet printer tech to fire off very short bursts of fragrance -- to tech lovers in Japan while still tweaking and refining it. Primarily aimed at helping healthcare professionals in assessing a patient's sense of smell, the Fragrance Jet II has a high degree of control granularity, permitting the varying of both intensity and duration of a scent, which in turn can provide a very accurate measurement of a given person's olfactory acuity. A mobile prototype has also been trotted out (pictured above), hinting at the possibility of eventually shrinking these modules to fit inside cellphones and thus leading us to an awesome future of customizable "incoming call fragrances." Awesome indeed. Video after the break.
