The aroma-emitting Kaoru Digital Signage display will be appearing in front of a Tokyo beer hall called Kirin City from October 21 and will assault the noses of passers-by with scents of orange and lemon and the eyes with video of foaming jugs of beer.
Apparently, the men in suits reckon the citrus is “associated with beer” so the field test resulting in crowds flocking to the bar like journalists to, well, a bar will show that they’re correct. Either way, each installation uses ultrasound to vaporize aromatic oils and can waft the result over 500 cubic meters.
