Abstract

A pedometer includes an activity amount acquisition unit that acquires an activity amount of a user, an index acquisition unit that acquires an index relating to the activity amount, and an index output unit that outputs the acquired index. The index acquisition unit includes an activity age acquisition unit that acquires an activity age represented by a standard age of a person who does the same amount of activity as the activity amount acquired in a unit period, using body information of the user, and acquires an index enabling the active age to reach a target activity age, based on the acquired activity amount.

Claims

1. An activity meter comprising:

an activity amount acquisition unit arranged and programmed to acquire an activity amount of a user;

an index acquisition unit arranged and programmed to acquire an index relating to the activity amount; and

an index output unit arranged and programmed to output the index acquired by the index acquisition unit;

wherein

the index acquisition unit;

includes an activity age acquisition unit arranged and programmed to acquire an activity age represented by a standard age of a person who does a same amount of activity as an activity amount acquired in a unit period, using body information of the user;

is arranged and programmed to acquire the index to enable the active age to reach a target activity age, based on the activity amount acquired in the unit period;

includes a target activity amount acquisition unit arranged and programmed to acquire a target activity amount representing an aggregate amount of activity done in the unit period by a person of the target activity age;

is arranged and programmed to acquire an index, using the acquired target activity amount;

compares an activity amount of the user acquired by the activity amount acquisition unit within the unit period with the target activity amount acquired by the target activity amount acquisition unit, and acquires the index based on a comparison result; and

computes a difference between an intermediate activity amount representing an activity amount from a start of the unit period acquired by the activity amount acquisition unit to partway from the start of the unit period and the target activity amount acquired by the target activity amount acquisition unit, and acquires the index based on a computed difference;

the unit period includes a plurality of time slots;

the activity meter further comprises a storage unit arranged to store a representative value for each time slot of the activity amount acquired by the activity amount acquisition unit in association with the time slot; and

the index acquisition unit;

includes a predicted activity unit arranged and programmed to acquire a predicted activity amount in the unit period, using the representative value stored for each time slot in the storage unit and the intermediate activity amount; and

is arranged and programmed to acquire, as the index, a predicted activity age representing an activity age acquired using the acquired predicted activity amount and the body information of the user.

2. The activity meter according to claim 1, wherein the body information includes a basal metabolic rate of the user.

3. The activity meter according to claim 1, wherein

the activity amount acquisition unit includes a calories burned acquisition unit arranged and programmed to acquire calories burned by the user as the activity amount;

and

the activity age acquisition unit is arranged and programmed to acquire an activity age represented by a standard age of a person who burns a same amount of calories as calories burned acquired in the unit period, using body information of the user.

4. The activity meter according to claim 3, wherein

the activity amount acquisition unit includes an exercise intensity acquisition unit arranged and programmed to acquire an exercise intensity of the user as the activity amount;

and

the calories burned acquisition unit acquires calories burned in the unit period, from the body information and the exercise intensity of the unit period acquired by the exercise intensity acquisition unit.

5. The activity meter according to claim 1, wherein the index acquisition unit is arranged and programmed to:

acquire a standard activity amount of a person of the predicted activity age in the unit period;

compute a standard intermediate activity amount from the start of the unit period to partway from the start, based on the acquired standard amount of intermediate activity; and

compare the computed standard intermediate activity amount with the intermediate activity amount of the user, and to acquire the index based on a comparison result.

6. The activity meter according to claim 1, wherein the index acquisition unit compares the activity amount of the user in a given time slot acquired by the activity amount acquisition unit with the representative value of the corresponding activity amount in the same time slot stored in the storage unit, and acquires the index based on a comparison result.
