Extended reality is a catch-all to refer to

augmented reality Augmented reality (AR) is an interactive experience that combines the real world and computer-generated content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be de ...

(AR) and virtual reality (VR). Sometimes the abbreviation “XR” is used to refer to both. The technology is intended to combine or mirror the physical world with a "digital twin world" that is able to interact with each other. The fields of virtual reality and augmented reality are rapidly growing and being applied in a wide range of ways, entertainment, marketing, real estate, training, and remote work.

Multisensory extended reality

Multisensory extended reality (XR) integrates the five traditional senses, including sight, hearing,

smell Smell may refer to; * Odor, airborne molecules perceived as a scent or aroma * Sense of smell, the scent also known scientifically as olfaction * "Smells" (''Bottom''), an episode of ''Bottom'' * The Smell, a music venue in Los Angeles, Californ ...

, taste and touch. Perception involves signals that go through the nervous system, as vision involves light striking the retina of the eye, the smell is mediated by odor

molecules A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and bioche ...

Scent is prominent in multisensory extended reality, as in biology, the olfactory system is integrated through the sensory nervous system. Multisensory experiences have elements of neuromorphic engineering, cognitive science,
