In recent years, thermal display has been studied intensively in order to represent a more realistic tactile quality of the object. Since human feels the temperature of the air without touching other objects, it is necessary to present thermal sensation in a non-contact manner. Studies on non-contact heat display have been explored; however, few studies have reported on a device that can display cold in a non-contact manner. In this study, we propose a non-contact cold thermal display using a low-temperature heat source—vortex tube, which can generate ultra-low air temperature when supplied with compressed air. We developed a cooling model that relates the flow velocity of cold air with the absorbed heat from skin; we implemented a prototype system that can control the flow velocity of the generated air; and we conducted an experiment to examine the cold sensation that the system can present. Our results revealed that various cold sensations can be generated so that the faster the flow velocity, the colder a user would feel.
