“Smell-o-vision” smell what you see screens give a noseful

TV screens visually and aurally transmit their output, 3D in the past few years was considered to be the latest, not anymore. A bunch of scientists from Japan’s Tokyo University of Agriculture and Technology have managed to add the 4th D to screens (not in geometric sense of word), smell what you see on the screen or “Smell-o-vision” as it’s known. Imagine the effect when you can smell the chicken wings of a KFC advert screen, mouth-wateringly awesome!


Haruka Matsukura of the university along with his colleagues has invented the LCD that can emit smell. It works by continuously feeding odours from vaporising gel pellets into four air streams, one in each corner of the screen. These air streams are blown out parallel to the screen’s surface by fans at varying strength and direction. At the moment the screen can emit only one particular smell at a time. The amazing LCD was showcased at the IEEE Virtual Reality Conference in Orlando, Florida last week.
