Bangalore: What about getting the smell of exotic food items shown in a cookery show? How about identifying the best flavor of perfume that is shown in the television? All these are going to be possible soon. Japanese scientists have developed a 'Smell-O-Vision' TV which they say could emit the exact smell of the picture on display. Something similar was developed in the U.S. in the '60s, with scents released from sachets hidden in the seats to make cinema audiences more engaged with the entertainment.
"We are using the ink-jet printer's ability to eject tiny pulses of material to achieve precise control ," said Lead Researcher Kenichi Okada of Keio University, Tokyo. The TV, according to scientists, will release a candy floss smell when the image shows a fairground and can even emit the briny scent of the seaside when people look at their holiday photos. The technology used in the television makes printers to spray small amounts of scent rather than ink.The Japanese team adapted a Canon printer to squirt four "ingredient" scents and managed to get hints of mint, grapefruit, cinnamon, lavender, apple and vanilla, for a fraction of a second. However, the smells took too long to clear the auditorium and they were scrapped. Previous attempts to add smell to films has included numerous additions of perfume, such as putting scent-soaked cotton wool by a fan blowing over viewers to squirting it from a balcony.
