Before a person has a car accident, he may have several “close calls.” These “close calls” may cause a person to experience tension and fear. People experience the “fight or flight reaction” (FFR) under such circumstances, as it is known that people exhibit the FFR when they feel anxiety, strain, or threat. If the manifestation of the FFR in a driver can be determined using a biological measurement, it would be an extremely effective indicator that might help in the prevention of car accidents. In this research, we conducted FFR-arousing experiments using a driving simulator, and the STSDA method was used to detect spatio-temporal changes in the skin temperature on facial skin thermograms accompanying the occurrence of the FFR.
