    More Annoying Than 3-D: Smells From Your Television

    Does 3-D television seem like a waste of time to you?   Perhaps you will like Smell-O-Vision more.

    Or not.  Even if you like neither of those things, they are waypoints on the path to immersive, interactive environments.  So buy this stuff today and some day we Science 2.0 folks can solve mysteries on the Holodeck with Data from "Star Trek: The Next Generation."

    Television programming executives want to be able to trigger your emotions as effectively as possible so engineers have focused on sight and sound - but that doesn't mean it has to stop there.   Wouldn't Pizza-Hut love to advertise right after the characters on a program eat some pizza and you can smell it?   Indeed they would.   

    A two year experiment by researchers at the University of California, San Diego, and Samsung Advanced Institute of Technology (SAIT) in Korea (ick - the private sector does science??) has resulted in a proof-of-concept paper in Angewandte Chemie where they demonstrate that it is possible to generate odor from a compact device small enough to fit on the back of your TV - with potentially thousands of odors. 

    "For example, if people are eating pizza, the viewer smells pizza coming from a TV or cell phone," said Sungho Jin, professor in the departments of Mechanical and Aerospace Engineering and NanoEngineering at the UC San Diego Jacobs School of Engineering. "And if a beautiful lady walks by, they smell perfume. Instantaneously generated fragrances or odors would match the scene shown on a TV or cell phone, and that's the idea."

    Jin and his team of graduate students used an X-Y matrix system in order to minimize the amount of circuitry that would be required to produce a compact device that could generate any odor at any time. The scent comes from an aqueous solution such as ammonia, which forms an odorous gas when heated through a thin metal wire by an electrical current. The solution is kept in a compartment made of non-toxic, non-flammable silicone elastomer. As the heat and odor pressure build, a tiny compressed hole in the elastomer is opened, releasing the odor.

    Whether TV and cell phone audiences and advertisers want smells controlled by someone else are a different issue, this group wanted to find out whether it's possible. 

    "It is quite doable," said Jin. 

    Without an X-Y matrix system, thousands of individual controllers would be needed to accommodate the range of odors required for a commercial system. "That's a lot of circuitry and wires," said Jin. By comparison, using the X-Y system, 200 controllers (100 on the X-axis multiplied by 100 on the Y- axis) would selectively activate each of the 10,000 odors.

    The UCSD team tested their device with two commercially available perfumes, "Live by Jennifer Lopez," and "Passion by Elizabeth Taylor." In both cases, a human tester was able to smell and distinguish the scents within 30 centimeters of the test chamber. When the perfumes were switched, the tester was exposed to coffee beans, which is the common practice for cleansing a tester's sense of smell in perfume development.

    "This is likely to be the next generation TV or cell phone that produces odors to match the images you see on the screen." said Jin. The multi-odor concept was initiated by Samsung's research and development group, headed by Jongmin Kim at SAIT. They came to UCSD with a request for a practical means of accomplishing such a vision.

    The possible scenarios are endless. A romantic comedy opens with two harried people stopping by their favorite coffee shop to fuel up before work. They are about to meet in some impossibly adorable way. But you're too distracted by the hazelnut latte that looks so good you think you can smell it. And you can. Thanks to the compact odor-generating device attached to the back of your TV set. Unless the scent is fading, in which case you just need to buy a new one like you would to replace the ink cartridge on your printer.

    Next steps in the research would include developing a prototype and demonstrating that it is reliable enough to release odors on cue and scalable to the size needed for consumer electronics like TVs and cell phones. And there are a few other considerations. For example, perfume companies could let you sample new scents through TV, but your TV's odor-generating device would have to carry that particular perfume meaning the device probably needs to be upgradable like software for your home computer. And TV producers will probably want scents that are tailored to match the personalities of their characters.

    "That's a logistics problem," said Jin. "But in specific applications one can always think of a way."

    given that people smell things differently from each other, chemical sensitivity issues and that smells are strongly linked to memory, I think this is a dangerous path - you never know what might be triggered for a person

    I for one, would not be buying a smell-capable tv - advertising is invasive enough without literally stinking up my house

    I would buy one if we could customise the odors emitted. I do NOT want the smells of steak, meat-lovers pizza or other such crap stinking up my house. It's bad enough I have to have them visually. And I could probably do without the smells of rotting dead bodies from CSI, vomit and farts from various comedies, etc..

    Television and advertisers refuse to even let us control what volume commercials will be, you think they will let us block out smells??

    Perhaps if they have smell-o-vision, they can also come up with taste-o-vision (and, of course, touch-o-vision).  That might resolve some of those basic problems. 

    Of course, on my planet, that is referred to as "reality", which is what it seems they want to replace.

    For the record ... all these sensory enhancements to television are seriously dangerous and will present no end of problems should it ever become available.
    I expect that the porn industry is already working on a narrow aspect of touch o vision

    As if high definition didn't already make porn gross enough!

    And then people will be walking around with noseplugs as well as earplugs...
    I don't know how much successful this new technology will be? Using the concept of smell when a particular object appears on the TV is innovative but to an extent it can be irritating. Just imagine the perfume which a particular model wears is not suitable to your sense of smell? Naturally, you would end up running away from the room. That is really a problem with this technology.
