Abstract

A wearable mobile device and a method of detecting a biosignal with a wearable mobile device are provided. A method of detecting a biosignal with a wearable mobile device involves determining whether a wearable mobile device is closely attached to a user; and providing a biosignal-based service in response to the wearable mobile device being determined to be closely attached to the user.

Claims

1. A method of measuring a biosignal, the method comprising:

determining whether a wearable mobile device is closely attached to a user; and

providing a biosignal-based service in response to the wearable mobile device being determined to be closely attached to the user.

2. The method of claim 1, wherein the providing comprises:

executing a program for measuring a biosignal from the user or a program that uses a measured biosignal; and

providing a result from the executed program as the biosignal-based service.

3. The method of claim 1, wherein the determining comprises:

measuring a range or a position at which the wearable mobile device contacts the user; and

determining that the wearable mobile device is closely attached to the user in response to the measured range satisfying a predetermined standard value or in response to the measured position corresponding to a predetermined skin area of the user.

4. A method of using a wearable mobile device, the method comprising:

attaching a bracelet comprising a sensor to an user;

determining whether the sensor is closely attached to the user based on a movement of the bracelet during attachment to the user; and

sensing the biosignal from the user by activating the sensor in response to the sensor being determined to be closely attached to the user.

5. The method of claim 4, wherein the determining comprises:

placing an analog front end of the sensor in contact with a body of the user; and

determining that the bracelet is closely attached to the user in response to the analog front end being not in a leadoff state.

6. The method of claim 4, wherein the determining comprises:

sending a microcurrent to a body of the user through the analog front end of the sensor; and

determining that the bracelet is closely attached to the user in response to an impedance measured based on a return of the sent microcurrent satisfying a predetermined value.

7. The method of claim 4, wherein the bracelet further comprises an additional sensor for determining whether the bracelet is closely attached to the user, and

wherein the determining comprises:

determining that the bracelet is closely attached to the user in response to the additional sensor entering an operating state based on a body position at which the bracelet is attached to the user.

8. The method of claim 4, wherein the sensing comprises:

identifying an activated sensor based on a position at which the bracelet is closely attached to the user; and

sensing the biosignal by the identified sensor.

9. The method of claim 4, further comprising:

in response to determining that the bracelet is closely attached to the user, executing a program associated with the biosignal or adjusting a system environment to be a predetermined value.

10. The method of claim 4, further comprising:

outputting a result of the determining of whether the bracelet is closely attached to the user.

11. A wearable mobile device, comprising:

a bracelet configured to be attached to a user by surrounding a body of the user;

a determiner configured to determine whether the bracelet is closely attached to the user based on a movement of the bracelet during attachment to the user; and

a sensor unit comprising sensors configured to sense a biosignal from the user subsequent to activation in response to the determiner determining that the bracelet is closely attached to the user.

12. The device of claim 11, wherein an analog front end in the sensors is in contact with the body of the user, and

wherein the determiner is configured to determine that the bracelet is closely attached to the user in response to the analog front end being not in a leadoff state.

13. The device of claim 11, wherein the analog front end in the sensors is configured to send a microcurrent to the body of the user, and

wherein the determiner is configured to determine that the bracelet is closely attached to the user in response to an impedance measured based on a return of the sent microcurrent satisfying a predetermined value.

14. The device of claim 11, wherein the bracelet further comprises an additional sensor for determining whether the bracelet is closely attached to the user, and

wherein the determiner is configured to determine that the bracelet is closely attached to the user based on a body position at which the bracelet is attached to the user in response to the additional sensor entering an operating state.

15. The device of claim 11, wherein the sensor unit is configured to identify an activated sensor based on a body position at which the bracelet is closely attached to the user and sense the biosignal by the identified sensor.

16. The device of claim 11, further comprising:

a controller configured to, in response to the bracelet being determined to be closely attached to the user, execute a program associated with the biosignal or adjust a system environment to be a predetermined value.

17. The device of claim 11, further comprising:

an output unit configured to output a result of the determining of whether the bracelet is closely attached to the user.
