| Outline of Final Research Achievements |
In this study, the temporal resolution of human temperature sensation was evaluated in order to obtain design guidelines for a two-dimensional temperature distribution stimulation device. As an engineering application of the obtained findings, we fabricated a prototype temperature distribution stimulation device with a matrix wiring of multiple Peltier elements and confirmed that the spatiotemporal pattern of temperature stimulation is useful for tactile sensory presentation. In addition, a prototype of a flexible Peltier device was fabricated, and its usefulness and issues were clarified. Furthermore, based on the evaluation results of the temporal resolution of the human sensation of temperature, we constructed a system that can transmit vibration and temperature information as audio signals, and demonstrated the usefulness of the findings from this study with regard to the perceptual characteristics of the sensation of temperature.
