A smelling screen is a type of digital scent technology, unveiled in 2013, that combines a display screen, similar to a television or computer monitor, with an odor emitting device capable of pinpointing the smell to a specific portion of the displayed image.
Odor stored in tiny gel packets is emitted and blown parallel to the screen.
[2] By varying the speed and strength of each fan, an emitted odor is moved to a specific spot on the screen.
[3] In 2013, a group of researchers from the Tokyo University of Agriculture and Technology unveiled a prototype smelling screen to the public at the ACM/IEEE Virtual Reality Conference.
[citation needed] The product is in the early stages of development with no plans for commercial distribution in the near future.
