In an aging society with a declining birthrate, increasing travel opportunities for the elderly will lead to increased revenue in the tourism industry, but simultaneously, consideration must be given to fatigue and injuries caused by unperceived fatigue. Therefore, this paper focuses on walking. Recently, the measurement of gait and analysis of gait data have been widely studied. However, most of the studies that analyze gait are aimed at understanding the health status of walkers, and there are few studies that accurately measure the degree of fatigue of the body. In this study, we developed a device to measure gait data to analyze the degree of body fatigue, and to verify a method to quantify the degree of fatigue. The device was created with a sensor that measures pressure on the sole of the foot and an IMU. The gait data were analyzed using t-SNE and SVM. From the experiment, we could classify the gait data and determine the degree of fatigue. It is expected that this device will be able to detect fatigue during sightseeing.
