Objective With the increasing affordability of virtual reality (VR) technology, VR exergames are emerging as promising tools for promoting physical activity and engagement among older adults. However, little is known about how VR-generated game metrics and user experience data evolve over time and influence long-term adherence. This study examined the feasibility of a custom VR exergame- Seas the Day -for at-home use during the COVID-19 lockdown. Methods Thirteen community-dwelling older adults completed 18 seated VR sessions over 6 weeks (3×/week), integrating Tai Chi, rowing, and fishing activities. Automatically recorded in-game metrics included rowing repetitions, Tai Chi completion time, fishing response times, distance traveled, and in-game errors. A difficulty-adjusted performance index (DAPI) was computed using session one as baseline to track progress over time. Participants also completed a Game User Experience Scale at weeks 3 and 6. Results Most participants showed improving or stable performance across sessions, with a smaller subset declining, highlighting individual differences. Significant gains were observed in Tai Chi completion time, rowing efficiency, and fishing response times. DAPI results confirmed overall upward performance trends despite repeated exposure. Game User Experience ratings remained high, particularly for enjoyment and ease of use, indicating sustained engagement and adherence. Conclusion Custom VR exergames can support physical activity and engagement among older adults in home settings, even during periods of social restriction. Game metrics and self-reported experience offer complementary insights into feasibility, adaptability, and individualized progress, underscoring VR exergaming's potential to promote well-being while emphasizing the need for personalized engagement strategies.
