According to the Ministry of Health, Labour and Welfare, it has been reported that the top three factors leading to the need for support are frailty due to aging, fractures and falls, and joint diseases. These are related to a decline in walking ability, making it important for active seniors to prevent this decline. However, there are challenges such as the need for specialized equipment and guidance from experts for walking training, as well as the tendency for motivation to decrease due to the monotonous nature of walking exercises. Therefore, we are developing a walking evaluation and training system that does not require expert intervention, can be used in daily life, and allows for enjoyable training. Specifically, we are building an AI for generating target walking patterns that takes into account individual physical differences, developing a walking feedback training system, and creating a walking motivation support system using VR video generation AI that reflects real-world spatial information. Additionally, we conduct gait assessments through motion analysis and emotional evaluations through biometric information measurement for each assessment.
