Abstract

An exercise detection apparatus determines body movements based on data detected by a detection unit, judges movement states for each body movement based on data detected by the detection unit, corrects the movement states based on a predetermined rule, calculates an exercise state of a user based on a result of the judgment, and stores the calculated exercise state in a storage unit. Accordingly, it is possible to provide an exercise detection apparatus capable of reducing erroneous judgments of the exercise states of the user.

Claims

1. An exercise detection apparatus comprising a main body unit, a control unit, a storage unit, and a detection unit,

wherein the control unit includes:

a first judgment means that judges body movements based on data detected by the detection unit;

a second judgment means that judges a movement state for each of the body movements based on data detected by the detection unit;

a calculation means that calculates an exercise state of a user based on the respective judgment results from the first judgment means and the second judgment means;

a storing means that stores the exercise state calculated by the calculation means in the storage unit; and

a correction means that corrects the movement state based on a predetermined rule,

wherein the predetermined rule is a rule for correcting the exercise state based on a transition of the exercise state; and

the transition occurs between the body movement that is a target of the judgment and body movements before and after the body movement that is a target of the judgment.

2. The exercise detection apparatus according to claim 1,

wherein the predetermined rule is a rule that, for transitions of the exercise state between the body movement that is a target of the judgment and the body movements before and after the body movement that is a target of the judgment, corrects an abnormal transition differing from a transition that can occur to a non-abnormal transition.

3. The exercise detection apparatus according to claim 2,

wherein for the exercise states calculated by the calculation means for each body movement in a range of a predetermined number of body movements from before to after the body movement that is the target of judgment,

the abnormal transition is a transition in the case where the exercise states of the first and last body movements are the same and body movements of an exercise state that differs from the exercise state of the first and last body movement make up less than half of the range of body movements, and

the non-abnormal transition is a transition in which the exercise states of the first and last body movements are the same and the exercise states of the body movements in the range are the same.

4. The exercise detection apparatus according to claim 1,

wherein the exercise state is a combination of the body movement and the movement state.

5. The exercise detection apparatus according to claim 1,

wherein the detection unit detects an acceleration value in at least one axial direction;

and

of the exercise states of the user, the first judgment means judges the body movement based on the acceleration value detected by the detection unit.

6. The exercise detection apparatus according to claim 1,

wherein the detection unit detects an absolute pressure value;

and

of the exercise states of the user, the second judgment means judges the movement state based on the absolute pressure value detected by the detection unit.

7. The exercise detection apparatus according to claim 1,

wherein the control unit further includes:

an exercise intensity specification means that specifies an exercise intensity based on the exercise states stored in the storage unit; and

an exercise amount calculation means that calculates an exercise amount using duration times of the respective exercise states stored in the storage unit and the exercise intensity specified by the exercise intensity specification means.

8. A control method for an exercise detection apparatus that includes a main body unit, a control unit, a storage unit, and a detection unit,

wherein the control unit executes:

a step of judging a body movement based on data detected by the detection unit;

a step of judging a movement state for each of the body movements based on data detected by the detection unit;

a step of calculating an exercise state of a user based on a result of the judgment;

a step of storing the calculated exercise state in the storage unit; and

a step of correcting the exercise state based on a predetermined rule, wherein the predetermined rule is a rule for correcting the exercise state based on a transition of the exercise state; and

the transition occurs between the body movement that is a target of the judgment and body movements before and after the body movement that is a target of the judgment.
