Presentation of Odor in Multi-Sensory Theater

This paper discusses an approach to implement and evaluate odor display, with the goal of using it in multi-sensory theaters. A display system that mixes odors with an arbitrary ratio was developed, and a sensor system that is capable of measuring the concentration in a relatively short time period using a sample and hold function was devised. Experiments clarified the time delay and attenuation of the concentration in the transmission of an odor from the display to a user, and the feasibility of utilizing a quantitative mixture of odors was confirmed.
