Display system for advertising image with scent and psychological effect

Abstract

We propose a new method in which scents are ejected through the display screen in the direction of a viewer in order to enhance the reality of the visual images. A thin LED display panel filled with tiny pores was made for this experiment, and an air control system using a blower was placed behind the screen. We proved that the direction of airflow was controlled and scents properly travelled through the pores to the front side of the screen. Moreover, the effectiveness to an advertising field of this system was estimated by simulating an actual situation in which various advertisements are around using the immersive VR System. The subjects' eye movements and impressions, when they look at the scented advertisements while walking, were analyzed. © 2011 Springer-Verlag Berlin Heidelberg.
