3. INTRODUCTION AIM: Until now, online communication involves only three senses they are, sense of touch ,sense of hearing and sense of sight. Fourth one is in its developing stage that is ,sense of smell. Digital scent technology (or olfactory technology) is the engineering discipline dealing with olfactory representation. Digital scent technology is the main application of e-nose. With digital scent technology, it is possible to sense, transmit & receive smell through internet. This sensing part of this technology works using  olfactometers  and electronic noses.

4. PREVIOUS SYSTEM: Until now, online communication involved only two of our senses 1.sense of sight 2.sense of hearing. PROPOSED SYSTEM : A new technology targets on sense of smell .

5. EVOLUTION OF DIGITAL SMELL How it was Invented : For the user to feel more realistic effects of movies the very new facility of digital smell in movies or in games have been introduced. The basic idea for this was given by the perfume making companies for the advertisements of their perfumes . Founders : “ Dexster Smith and Joel Lloyd Bellenson ”, experts in bioinformatics and genomics, started from the following idea: “If we can find the essence of a biological smell and build a profile, we can digitalize and broadcast it

6. PRINCIPLES FOLLOWED Basic Principle of e-Nose : Fundamental principle of artificial nose is that each sensor in the array has different sensitivity. The pattern of response across the sensors is distinct for different odors . Different e-noses use different types of gas sensors which form heart of enose .

7. Sensing an ordant : The sensor’s response is recorded and delivered to the signal processing unit and then it is converted into electronic signal by using a transducer and is processed by using the signal processing unit

8. DIGITAL SCENT COMMUNICATION

9. DIGITAL SCENT COMMUNICATION The e-nose detects the smell molecules and it is indexed based on two parameters. The scent is indexed according to its chemical makeup and its place in the scent spectrum. The chemical makeup can be detected by the electronic nose . The indexed scent is digitized into a small file by olfactory signal processing. This file is sent as an attachment to the recipient’s computer . At the receiving end, there will be a personal scent synthesizer and air cannon. The personal scent synthesizer reproduces the smell and the air cannon direct the smell to user’s nose .

10. At the receiving end, there will be a personal scent synthesizer and air cannon. The personal scent synthesizer reproduces the smell and the air cannon direct the smell to user’s nose.

11. BROADCASTING OF SMELL It is carried out at the following 3 levels 1.Digitized Scent : A scent is indexed along two parameters , its chemical makeup and its place in the scent ”spectrum” and then digitized into a small file. 2.Broadcast : The digital file is scent, attached to enhanced web content. 3.Smell Synthesizer: The smell synthesizer means the device which is used to generate the smells.

12. HARDWARE DEVICES Smell Synthesizer iSmell Catridge

13. SMELL SYNTHESIZER Smell synthesizer is the device ,which is used to generate the smells . iSmell is a device used to produce the gas using computer . There are various types of smell synthesizers available in the market, but for computer the smell synthesizer is made by digiscents industry

14. iSmell The iSmell is a peripheral device, about the size of a PC speaker that connects to a PC via a serial or USB port. It uses consumable cartridges which are used and replaced similar to the way ink jet printers use ink cartridges . The iSmell device reads a digital scent file, creates a smell from a "palette'' .

15. CATRIDGE The cartridge will contain chemicals in the form of either natural oils or synthetic fragrances that will be activated by either heat or air pressure , when you send signal from your computer. Currently 128 chemicals are stored in a cartridge . Similar to an ink jet printer .

16. Applications There are many applications for digital scent technology such as: S end scented email W atch scented DVD's Sample a perfume from a beauty product's website Smell the assortment of freshly brewed coffees for sale in their online store . Education : Teaching tool in Geography, History and Sciences. Entertainment: Scent will make music, movies and interactive games life like and immersive

17. Effects of Digital Smell for Different Sites Over the Theatre : After few years virtual theatres will enter in to the market. This virtual theatre is basically the concept of the virtual reality . For example, if we are watching movie in a virtual theatre ,there we see burning of a tier then we can feel the smell by using this technology. Over the Television : After some time over television will came with more picture quality , better voice as well as iSmell device, which will create more interest in watching the television .

18. Over the Internet DigiScent s technology will be used to add a new dimension to e-commerce and entertainment technology adding scent to movies, online advertising and interactive games are just a few of the possibilities . E-mail Alive with smell: Of all the uses for scentware , this one scares be most the ability to send emails with smells anybody can design . Sure , it’ll add a fun new dimension to birthday when you can send an electronic postcard with nice music and a dozen roses that smell real,etc .

19. Advantages It can be used without fall over hours, days, weeks and even months and can even circumvent problems associated with the use of human panels such as individual variability. e-nose is a compact device and so it is portable and reliability is very high. It can identify simple molecules which cannot be accomplished by human nose.

20. Disadvantages Cost of an e-nose ranges from $5000 to $100,000,which is very high. Another disadvantage has been the delay between successive tests

21. Conclusion A Scent has a strange power over human beings. “The Sense of smell is closely tied to memory and emotion , making scent a powerful way to reinforce ideas ”. Hence we conclude that this digital smell will revolutionized the world. And at every place we will require this device, such as for scented mail, scented Movies , scented songs we will require this device. This device will become our need in future.

22. FUTURE SCOPE Under their system a person could send an 'encoded' message from one computer to another, and then person will get the message in the form of smell. Then this smell will be cached by the input ismell device then given to the translator which will translate these release chemicals to the message form.
