​​What is Digital Smell Technology?

Until now, online communication involved only two of our senses, sense of sight & a sense of hearing. Soon it will involve the third, the sense of smell using a nose. Digital smell technology is the main application of e-nose. With digital scent technology, it is possible to sense, transmit & receive smell through the internet.
For the user to feel more realistic effects of movies the very new facility of digital smell in movies or in games has been introduced. The basic idea for this was given by the perfume making companies for the advertisements of their perfumes.
Digital smell works by continuously feeding odors from vaporizing gel pellets into four air streams, one in each corner of the screen. These air streams are blown out parallel to the screen’s surface by fans, and varying the strength and direction of them spreads the scent to any given spot on the screen.

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” of 128 chemicals stored in a cartridge, and then wafts into the air with a small fan.
