The document discusses physical inactivity and ways to increase physical activity levels using gamification. It presents results from interviews and an online survey of 942 fitness tracker users. Reaction-based notifications that provide step count updates were found to be motivating. Gamification elements like challenges and competitions that allow users to compare progress against others were also found to increase enjoyment and motivate users to be more active. While users were motivated by both intrinsic factors like learning and enjoyment as well as extrinsic rewards, intrinsic motivation had a stronger influence on behavior. The discussion considers how gamification can motivate physical activity but may not directly translate to increased activity levels and whether impacts are sustained over time.
