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 emo-tions, 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 inten-tionally, 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 expe-riences. This includes smart control in various uses, frequently offering mul-tisensorial interfaces. We can observe this in numerous appliances today. This paper discusses scent interfaces for controlling scent diffusion, investi-gating on the space between a scent diffuser device and its control source to define and categorize Scent Interfaces.
