Abstract
In this paper, a display system that can present a virtual airflow and/or odor source on a screen is proposed. The system can give the user a sensation that airflow and/or odor is coming from a certain position on a computer screen. Four fans are used in the proposed display and are placed at the four corners of the screen. Airflows generated by the fans are collided with each other and deflected from their original courses. Thus, directed airflow is generated toward the user from a specific position on the screen (a virtual airflow source). By introducing odor vapor into the airflows, odor distribution spreading from a specific position on the screen (a virtual odor source) is generated. The results of airflow velocity and odor concentration measurements show that the virtual airflow/odor source can be moved to an arbitrary position on the screen by adjusting intensities of the airflows.
