A survey of technologies related to localized scent delivery by using vortex rings is provided. Scent delivery is one of important technical fields that compose olfactory displays. Among various techniques for scent delivery, use of vortex rings has been proposed to deliver scents relatively long distance through free space. Equipment that expels vortex rings is called an air cannon. Although several researchers have designed and built air cannons as parts of their display systems, design parameters of air cannons have not been discussed systematically. In this paper, technical fields that compose olfactory displays are briefly surveyed to clarify the standpoint of scent delivery techniques, and then relationship between design parameters of an air cannon and its performance is discussed. In addition, some ongoing studies on air-cannon-based olfactory displays are introduced.
