Scent interfaces definition: Diffuser devices interaction and control

Abstract

Interface’s definition, in its various perceptions, is explained as the relation between different systems interaction with or without human intervention. Scents are perceived with a direct link to the brain cortex that handles emotions, often triggering immediate emotions [1]. Aroma cannot be seen, heard or touched; it must be dispersed in the air to be perceived. To do so intentionally, a diffusing device built with the purpose of spreading smell into an environment is usually needed and it requires a controlled source. High-tech scent diffusers make use of new technologies reaching new usage and experiences. This includes smart control in various uses, frequently offering multisensorial interfaces. We can observe this in numerous appliances today. This paper discusses scent interfaces for controlling scent diffusion, investigating on the space between a scent diffuser device and its control source to define and categorize Scent Interfaces.
