Machine olfaction is the automated simulation of the sense of smell. An emerging application in modern engineering, it involves the use of robots or other automated systems to analyze air-borne chemicals. Such an apparatus is often called an electronic nose or e-nose.
The properties of a compound relating to human olfactory perception includes its odour quality, threshold and intensity as a function of its concentration. The odour quality of a (odour-active) compound is assessed using odour descriptors in sensory descriptive analyses. [4] It shows the sensory–chemical relationship in volatile compounds.
Digital scent technology (or olfactory technology) is the engineering discipline dealing with olfactory representation. It is a technology to sense, transmit and receive scent -enabled digital media (such as motion pictures , video games , virtual reality , extended reality , the metaverse , web pages, and music ).
The electronic nose was developed in order to mimic human olfaction that functions as a non-separative mechanism: i.e. an odor / flavor is perceived as a global fingerprint. [7] Essentially the instrument consists of head space sampling, a chemical sensor array , and pattern recognition modules, to generate signal patterns that are used for ...
Olfactometers are used in conjunction with human subjects in laboratory settings, most often in market research, to quantify and qualify human olfaction. [1] Olfactometers are used to gauge the odor detection threshold of substances. To measure intensity, olfactometers introduce an odorous gas as a baseline against which other odors are compared.
Scentography is the technique of creating and storing odor by artificially recreating a smell using chemical and electronic means.. DigiScents Inc was among the more recent pioneers of the technology, developing DigiScent (later iSmell) in 1999 as a device that would plug into a computer's USB port and generate scents dependent on the online content being viewed.
It also may be time to invest in a new laptop if you are experiencing a system slowdown and random restarting on your Windows 11 PC, but I would recommend trying to fix the problem first before ...
The Lady and the Unicorn, a Flemish tapestry depicting the sense of smell, 1484–1500. Musée national du Moyen Âge, Paris.. Early scientific study of the sense of smell includes the extensive doctoral dissertation of Eleanor Gamble, published in 1898, which compared olfactory to other stimulus modalities, and implied that smell had a lower intensity discrimination.
