The idea of a computer controlled smell output display has been around for nearly 50 years but it is only recently that the technology has become more economically viable and commercially available, however it is still being developed.
Humans have difficulty is ascertaining the quantity of a smell but are very good at identifying qualities and differences in smells. There are many different methods for olfactory display. There is an airbrush-like system that uses compressed air to pick up liquid particles of scent and emit them. There are various systems that use heat to increase the evaporation of a scented oil or wax. It is also possible to use a mechanical scratch and sniff type system. Each system has its faults but different systems have optimal applications.
In the present nearly all multimedia applications have two main components, Audio and Visual stimuli. The aim of most applications is to immerse the user into the created world. Smell used properly could be a very powerful tool in recreating a world. Smell can bring someone straight backs to a childhood memory, if this were used effectively in a horror film for example; the viewer would be very easily scared. Issuing the effect that many contemporary horror films have recently been trying to emote. However there are possible problems with immersing a user too much into a computer simulated world. Although the debate between computer games manufactures and doting parents still rages on. Whether violent games breed violent people or violent people are attracted to violent games. If the former were true, creating a more immersive world through smell would mean that it would become difficult to separate game from reality. Possibly becoming a sociological issue.
The development of this technology could affect different parts of the art world as well. The film, Perfume: The Story of a Murderer, uses very clever camera, editing and CGI effects to portray smell on screen. If the olfactory display technology were widely accepted and used by filmmakers, large parts of the film would be greatly enhanced. Although the concept has been around for a long time, the execution is now near completion and will hopefully be available and affordable soon.
