 Hello, everyone. I am Takumi Hamazaki from UEC Japan. Let me talk about chemical-induced summer agri-illusion. Summer agri-illusion, where TGI is a phenomenon in which the warm and cold stimuli presented simultaneously produce a burning sensation or pain, as this is a safe way to present pain. It is mainly in situations such as pain presentation in VR. Previous TGI used patient devices or heat lamps to physically present temperature. However, this devices are bulky and consume a lot of energy. In contrast, we propose a method of presenting the TGI using chemicals, such as capsaicin and menthol, which are known to present hot and cold sensation by directories to rating some receptors. Our research question is, whether application of these chemicals will induce a summer agri-illusion? We compare the four conditions, only menthol, only capsaicin, mixture, and adjacent. Since there is a relay of several minutes between the application of capsaicin and menthol and the actual onset of sensation, a time delivers the application to each subject in the adjacent condition. The responses were based on three scales, temperature sensation, pain, and co-retative subjective evaluation. Here is a timeline result, for example, axis shows time and vertical axis shows temperature sensation from minus 0 to 4, and pain sensation from 0 to 4. The pain of the menthol condition and the mixed condition is always small, and the temperature sensation shows a monotonic decrease. Therefore, the mixed solution did not generate the summer agri-illusion. In contrast, the capsaicin and adjacent condition showed a monotonic increase in both pain and temperature sensation. Therefore, we examine differences between the two conditions by subjective evaluation. The responses for these burning sensations were similar in these two conditions. On the other hand, the capsaicin condition had more responses about worms, while the adjacent condition had fewer responses about worm and harp, and more responses about cool and cold, which is a typical response about summer agri-illusion. These results suggest that it is possible to generate the summer agri-illusion by applying them adjacent to each other. Interestingly, the mixed solution did not generate the illusion, which might be due to the masking effect. We must note that the time response may be slower than the previous methods. Conclusion, unlike previous TGA, we can present summer agri-illusion using only chemists. This may enable low-energy and compact pain presentation. Thank you for listening.
