Abstract

A biosignal measuring method and apparatus are provided. The biosignal measuring method includes verifying whether a measured biosignal is in a range, and controlling an operation of the biosignal measuring apparatus when the measured biosignal deviates from the range based on a result of the verifying.

Claims

1. A biosignal measuring method, the method comprising:

measuring a biosignal of a user wearing a biosignal measuring apparatus;

verifying whether the biosignal is in a reference range;

and

controlling one of a temperature of a contact area between the user wearing the biosignal measuring apparatus and the biosignal measuring apparatus and a change in grip between the user wearing the biosignal measuring apparatus and the biosignal measuring apparatus based on whether the biosignal deviates from the reference range.

2. The method of claim 1, wherein, in response to the biosignal being in a range less than the reference range, further comprising

performing one of an operation of generating heat in a measurement area in which the biosignal is measured and an operation of tightening the biosignal measuring apparatus to the user.

3. The method of claim 1, wherein, in response to the biosignal being in a range greater than the reference range, further comprising

performing one of an operation of cooling a measurement area in which the biosignal is measured and an operation of releasing a grip between the biosignal measuring apparatus and the user wearing the biosignal measuring apparatus.

4. The method of claim 1, further comprising:

verifying whether the biosignal is in the reference range based on the controlling; and

determining whether to end the controlling based on whether the biosignal deviates from the reference range.

5. The method of claim 1, wherein the biosignal is an electrical skin conductance.

6. A biosignal measuring method, the method comprising:

measuring a biosignal of a user wearing a biosignal measuring apparatus;

verifying whether the biosignal is in a threshold range;

performing one of an operation of generating heat in a measurement area in which the biosignal is measured and an operation of tightening the biosignal measuring apparatus to the user, based or whether the biosignal is less than a first boundary value of the threshold range, in response to the biosignal adjustment event; and

detecting whether the biosignal reaches a measurement range based on the performing.

7. The method of claim 6, wherein the detecting comprises:

detecting whether the biosignal exceeds the first boundary value of the measurement range based on the performing of the operation.

8. The method of claim 6, wherein, in response to the biosignal being greater than a second boundary value of the threshold range, further comprising

performing one of an operation of cooling a measurement area in which the biosignal is measured and an operation of releasing a grip between the biosignal measuring apparatus and the user wearing the biosignal measuring apparatus.

9. The method of claim 8, wherein the detecting of whether the biosignal reaches the measurement range comprises:

detecting whether the biosignal is less than or equal to the second boundary value of the measurement range based on the performing of the operation.

10. The method of claim 6, wherein the biosignal is an electrical skin conductance.

11. The apparatus of claim 6, wherein the first boundary value is a lower boundary value, and in response to the biosignal increasing to be greater than or equal to the lower boundary value, stopping the one of an operation of generating heat in a measurement area in which the biosignal is measured and an operation of tightening the biosignal measuring apparatus to the user.

12. The method of claim 9, wherein the second boundary value is an upper boundary value, and in response to the biosignal decreasing to be less than or equal to the second boundary value, stopping the one of an operation of cooling a measurement area in which the biosignal is measured and an operation of releasing a grip between the biosignal measuring apparatus and the user wearing the biosignal measuring apparatus.
