Nerds always RULE !!

April fool: on the first of April 2013, Google announced the launch of a new smell search feature, Google Nose. It was in beta mode, but its "aromabase" of more than 15 million "scentibytes" was sure to entertain, featuring such wondrous odors as airport terminal, used napkin and garlic breath.

Never Play With Nerds

IEEE Graduate Student Member Haruka Matsukura, IEEE Member Hiroshi Ishida, and their colleague Tatsuhiro Yoneda, demonstrated their Smelling Screen at the IEEE Virtual Reality Conference, held in March in Orlando, Fla. The screen, which they call an “olfactory display,” relies on two odor-releasing vents—one on the right side, the other on the left of an LCD TV screen—that are programmed to dispense up to eight different aromas. They described the prototype in their conference paper “Smelling Screen: Technique to Present a Virtual Odor Source at an Arbitrary Position on a Screen.”

During the demonstration, Matsukura, who led the research team, said he hopes their invention will enhance advertisements, video games, and museum exhibits, in addition to adding a new element to TV shows.

NOW SMELL THIS

Combining a movie with appropriate odors isn’t new—it actually first turned up more than 50 years ago. Smell-O-Vision, invented in the late 1950s, brought smells of other things beside popcorn to the movie theater. The technology had its debut in the 1960 film Scent of Mystery. The movie was released in three cities—New York, Los Angeles, and Chicago—and the theaters were equipped with vents near the screen aimed at the audience. Odors were released at specific points in the plot. In one scene, for example, wine barrels fall off a wagon, roll down a hill, and smash against a wall—at which point the scent of grapes wafted over the audience.

Unfortunately, the system had glitches. Moviegoers complained about loud hissing from the vents when the scents were dispersed and said the smells usually arrived too late for the on-screen action. In some parts of the theater, the smells were much fainter than in others, so some people had to audibly sniff the air in search of the scent. The movie tanked at the box office. Moviegoers also turned up their noses at other “smelly” systems such as AromaRama, which debuted almost simultaneously with Smell-O-Vision and piped in its smells through a theater’s air-conditioning system.

HOME ENTERTAINMENT

This time, it’s personal—unlike the original Smell-O-Vision, the Smelling Screen can fit inside a living room. The prototype that Matsukura’s team demonstrated at the conference measured 32 centimeters in height and 53 cm in length—about the size of a large personal computer monitor. The vents release odors automatically at preset intervals, while a pair of fans blow odors in various directions and thus create the illusion that the scent is coming from a specific point or object on the screen.

The scents originate from hydrogel pellets, called “aroma chips,” that are heated to produce vapor. The vapor is then released from tubes attached to the vents. So far, the researchers have only been able to generate one smell at a time, but they plan to develop cartridges preloaded with multiple scents that can be released at the same time.

 “The location of this virtual odor source can be shifted on the screen by adjusting the positions of the fans,” Matsukura says. In the demo, the smell of coffee appeared to emanate from the image of a coffee cup that appeared on the top-left corner of the screen.

“Sensory tests are being conducted with subjects to determine if they can correctly identify where on the screen the smell seems like it’s coming from, and encouraging results have been obtained so far,” he says. “Most users do not immediately notice the mechanism that runs the display system because the odor seems to come from the screen rather than the fans.”

Matsukura pointed out at the conference that bakeries, popcorn stands, and other food retailers already use the power of scent to attract customers. For example, Cinnabon, a maker of cinnamon buns, is said to pump the smells of spices and sugar into the air in its stores to attract customers. The Smelling Screen, if proven to be reliable, could potentially be a powerful new tool for advertisers, he says. If it was difficult to resist that sizzling steak before, wait until you’re hit with its enticing aromas each time it appears on your television!
