Demo of olfactory display with less residual odor

Abstract

An olfactory display is a device which provides various scents to a user. e integration of such olfactory stimulus with conventional VR system will strongly influence human emotion and create a more immersive experience. One of the main issues accompanied by the implementations is that the odorants spread into the ambient air and it makes the user confuse what smell is presented at that time. We tried to solve this with an innovative and simple design concept of the olfactory display: installation of the air intake and inner deodorant filter. Based on the method, we include olfaction in a VR game to provide the remarkable sensation to a user with clear and various smells presentation.
