In this paper, a system for interactive odor presentation based on computational fluid dynamics (CFD) simulation is described. The devices to present olfactory stimuli are called olfactory displays. To provide high-presence olfactory stimuli, a model of the virtual environment shown on the computer screen is provided to a CFD solver. The airflow field in the environment and the dispersal of odor molecules from their source are then calculated. The obtained odor distribution data is stored in a database. In the experiment, the user was allowed to move around in a virtual room shown on the computer screen. The odor with the appropriate intensity was released from an olfactory display device according to the user's position in the virtual room. The results showed that to modulate the odor concentration according to the user's relative direction to the odor source is effective to further improve the sense of reality.
