  • Publication number: 20250104838
    Abstract: In an activity support device, a plan acquisition means acquires a target physical activity amount of a user in a predetermined period and a predictive physical activity amount representing an expected expenditure of a physical activity amount. An expended physical activity amount acquisition means acquires an expended physical activity amount of the user up to a current time in the predetermined period. A total expended physical activity amount acquisition means derives a total expended physical activity amount of the user in the predetermined period, based on the predictive physical activity amount and the expended physical amount. An activity determination means determines a physical activity to the user from among physical activity options by comparing the target physical amount and the total expended physical amount. Accordingly, it is possible for the activity support device to support a user in making a decision regarding the physical activity.
