Engagement and Physical and Mental Fatigue for Artificial Intelligence-Based Personalized Strength Training Equipment

Tonal is a state-of-the-art workout system equipped with artificial intelligence, designed to cater to a high-end market where user engagement and satisfaction are paramount. Mental and physical fatigue have been identified as key factors that deter user engagement and reduce the likelihood of returning users. This study aimed to assess the mental and physical fatigue experienced by users while utilizing the Tonal equipment. Research indicates that changes in the eyes can reliably reflect both mental and physical fatigue; therefore, Tobii Pro II glasses, considered the gold standard in eye-tracking technology, were selected to monitor the changes in the eyes of the subject. The results revealed that users experience both physical and mental fatigue while using the equipment. However, the degree of fatigue observed in this study does not appear to significantly impact overall user engagement, as users demonstrated relatively quick recovery. Nonetheless, mitigating these fatigue-related barriers would further enhance user satisfaction and promote consistent engagement. To address physical fatigue, recommendations include implementing features such as overexertion monitoring, hydration reminders, and overtraining warnings. Similarly, mental fatigue can be reduced by simplifying the interface navigation to streamline the user experience and minimize cognitive load. By effectively reducing both physical and mental fatigue, these enhancements would lower barriers to continued use while developing an environment for the user that encourages sustained engagement and satisfaction.
