Smelling screen: Presenting a virtual odor source on a LCD screen

DOI

Description

The smelling screen is a new olfactory display that can generate a localized odor distribution on a two-dimensional display screen. The generated odor distribution is as if an odor source had been placed on the screen, and leads the user to perceive the odor as emanating from a specific region of the screen. The position of this virtual odor source can be shifted to an arbitrary position on the screen. The user can freely move his/her head to sniff at various locations on the screen, and can experience realistic changes in the odor intensity with respect to the sniffing location.
