Extra-high-quality audio devices, which is reproducible sound of broadband, have appeared in recent years. Such audio devices of broadband can feel like a deeper sense of realism as an air field by feeling the vibration of the air with entire body. This technology is expected application as sense of presentation technology. Using this technology, development of the new stimulus medium that is the field generating device, such as wrapped up in air is enabled. The purpose of this study is to create a completely new sense with the airflow stimulus termed “air-sensation” by using the air field. In this study, we measured the psychophysical quantities to clarify the cognitive characterization of air-sensation as a basic examination. Specifically, we measured the absolute thresholds to detect the air-flow stimulus and sensitivity characteristics with respect to the strength of the stimulus. Consequently, it was revealed that cognitive characterizations vary with the properties of signal waveform, stimulus-presentation site, and stimulus-presentation order.
