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 that is configured to be worn or carried by a user, the exercise detection apparatus comprising:

a main body unit, the main body unit including a display unit and a display switch;

a storage unit;

a detection unit; and

a control unit configured to;

judge whether predetermined movements of a body of the user are occurring based on data detected by the detection unit;

judge a movement state for the body across a predetermined unit of body movements based on data detected by the detection unit;

calculate an exercise state of the user during the predetermined unit of body movements based on the respective judgment results;

store the exercise state calculated by the control unit in the storage unit; and

correct a target exercise state based on a predetermined rule, wherein

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

the transition occurs between the target exercise state and exercise states before and after the target exercise state; and

the display unit displays the corrected target exercise state.

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 target exercise state and the exercise states before and after the target exercise state, corrects an abnormal transition to a non-abnormal transition.

3. The exercise detection apparatus according to claim 2, wherein

for the exercise states calculated by the control unit for each unit of body movements in a range of a predetermined number of units of body movements from before to after the unit of body movements that is the target of the exercise state calculation,

the abnormal transition is a transition in which the exercise states of the first and last units of body movements in the range are the same, and exercise states that differ from the exercise states of the first and last units of body movements in the range make up less than half of the exercise states of units of body movements in the range, and

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

4. The exercise detection apparatus according to claim 1, wherein the exercise state is a function of both the identity of the movements of the body 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

the control unit judges whether predetermined movements of the body are occurring based on the acceleration value detected by the detection unit.

6. The exercise detection apparatus according to claim 1, wherein

the detection unit detects absolute pressure values;

and

the control unit judges the movement state based on the absolute pressure values detected by the detection unit.

7. The exercise detection apparatus according to claim 1, wherein the control unit is further configured to:

specify an exercise intensity based on the exercise states stored in the storage unit; and

calculate an exercise amount using duration times of the exercise states stored in the storage unit and the exercise intensities of the respective stored exercise states specified by the control unit.

11. The exercise detection apparatus according to claim 7, wherein the display unit displays the exercise amount, and is contained in a housing with the detection unit.

8. A control method for an exercise detection apparatus that is configured to be worn or carried by a user, the exercise detection apparatus including a main body unit having a display unit and a display switch, a control unit, a storage unit, and a detection unit, wherein the control unit is configured to execute the control method comprising:

a step of judging whether predetermined movements of a body of a user are occurring based on data detected by the detection unit;

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

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

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

a step of correcting a target exercise state based on a predetermined rule, wherein

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

the transition occurs between the target exercise state and exercise states before and after the target exercise state; and

the display unit displays the corrected target exercise state.

9. The method according to claim 8, wherein the control unit method further comprises:

a step of specifying an exercise intensity of the exercise states stored in the storage unit; and

a step of calculating an exercise amount using duration times of the exercise states stored in the storage unit and the specified exercise intensities of the respective stored exercise states.

10. The method according to claim 9, wherein the exercise amount is displayed to a user who is wearing or carrying the exercise detection unit.
