DIGITAL SMELL TECHNOLOGY Digital scent.docx (Size: 13.24 KB / Downloads: 42) INTRODUCTION To smell is to believe! Scents have an immediate and compelling effect. The sensors in your nose, by contrast, can sense as many as 10,000 different odors. Scents are unambiguous and unmistakable. It is the medium that makes us decide instinctively. Until now, online communication involved only three of our senses. Soon it will involve a fourth, as new technology is being developed to appeal to our sense of smell. As broadcasting smell on the Internet would do wonders, consequently there has been a large amount of research into the effects of smell on human behavior. Smell is a potent wizard that transports us across thousands of miles and all the years we have lived. We can communicate by smell without knowing it. In fact the sense of smell could be said to be at the mind-body interface. CHRONOLOGICAL HISTORY The Return of the scent: A few years ago, Dexter Smith and Joel Bellenson were vacationing bio-technology executives found themselves overwhelmed by all the wonderful smells of Miami’s south beach. They thought about the idea of digitizing them and formed DigiScents to create the hardware and software necessary to digitize and reproduce smells. DigiScents Company had the basic outline of scent recording and reproduction technology ready for launching. After that a neurobiologist Linda Buck in 1991 discovered the family of genes responsible for odor detection. In 1998, researchers in Stuart Firestone’s lab at Columbia engineered a virus to stimulate a rat's odor receptors, heightening its experience of smell and theoretically, paving the way for the genetic "transplant" of receptors from one type of animal to another. In 1999 February: 1999, Oakland, California.-based DigiScents has been working on a way to encode smells into a computer file that can be delivered over the Internet in a number of ways, including embedding it in a Web page or sending it as an email attachment. It was also successful in the creation of a scent index and then used trial and error to fine-tune the odors, testing them on an odor output device they would design. BACKGROUND How do we smell: a brief introduction? Brief understanding of the sensory perception of smell is necessary to understand some fundamental facts about how computer generated smell can and cannot work by taking a quick look to the working of the human nose. The nose can distinguish more than 10 thousand different smells. This is because we have 20 million smell sensors in the inner part of the nostrils. Any color can thus be mapped in three dimensions. Mapping a smell would require a 1000-dimensional space. This is the fundamental problem of computerized smell production. The olfactory system can distinguish thousands of odors. The brain may interpret as different odors. The appropriate molecule and receptor fuse, a sequence of events is initiated. Scientists are just beginning to learn how the olfactory system works. They are discovering: 1. Processes thought to underlie odor recognition. 2. Ways odors may affect human behavior. 3. Strategies for helping people who suffer from anosmia. |
