However, the current information technology is still unable to break the sense of smell, taste and touch, to smell it, to break through the technical bottleneck of this sensory organ is that we must first understand how humans can "smell" flavor, the key is in the air particles , passed to his nose inside and then smell the taste, so the sense of smell digital equipment, is to do to receive particle data, and bring them to digital and digital sense of smell should also be able to taste the particles derive from the information

Human beings are equipped with visual, hearing, smell, taste and ability to touch the five senses through the visual and auditory communication can be more than 55% of the message to the other, and still there were still 45% of the information is provided by the human taste, smell and touch afford. If human beings can "five sense" together to achieve real-time transmission to achieve "virtual reality" It is just how exciting things.

Imagine you are watching the war films, the taste of smoke, bullets whistling pass by the sound ... ... as if you are a brave warrior in the battlefield on the gallop. Unfortunately, now you can just seated to watch the kind of smoke flavor can only rely on your imagination to complete.

In order to achieve an extension of the human sense of smell, national research institutes are working on the spread of odors. Toyota exhibition hall in Tokyo, there is a small movie theater, where the smell and movie images with real-time passed to the gallery audience. Example, the actor and actress movie pass by, the kind of women's fragrance will also be immediately passed to the audience. Although this is not part of communication transmission, but the attempt to pass on the way in terms of smell is greatly improved.

Have to achieve in the communication transfer images, sounds and smells of the simultaneous transmission more difficult. Through the three primary colors of light theory can reproduce almost all the colors out of realization of image transmission, while the sense of smell may be far from the constituent elements of information, not so simple. This requires odor sensors and odor synthesis technology. First felt by the smell the smell of sensor digitization of the data transmitted via the Internet, the recipient and through scent synthesizer will be to restore the odor out.

Japan's Shiseido company is developing a perfume scent through the network transmission devices. It required the user through the computer to confirm the smell, and then specify the specific device emitting a smell.

France Telecom is also studying the transmission through the network odor research. Need to connect your computer already contains a variety of scented "aroma generator", a user clicks on the site shown on perfume samples, will receive one of the sample information, then can use the "aroma generator" smell the smell of.

The nation's largest computer products exhibition "COMDEX" scent transfer samples on display there. This is called "iSmell" Synthesis of smell a bit like a shark fin devices, single-shape is very special, it built a variety of odor sources, cassette, by the composition of a variety of odor to achieve a variety of flavor, as the combination of the three primary colors of light theory to achieve the same odor combination.

If the human sense of smell can be extended to the network, it would be very meaningful. For example, in class looking Herbarium, the smell of plant names and learning together will greatly enhance the learning efficiency; in the hospital early in the evenings the smell of different distributed to regain up to the long-term hospitalized patients, but also to achieve medical fragrance therapy; in cosmetics advertising, also allows customers a variety of real-feel the flavor; in the game, the battlefield, the smell of smoke will greatly stimulate the game realism
