Abstract

Disclosed is an electronic device comprising a processor and at least one sensor circuit comprising at least a biometric sensor and a fatigue sensor. The processor may be configured so as to detect biometric data of an external object by means of the biometric sensor, detect fatigue data of the external object by means of the fatigue sensor if the biometric data exceeds a designated second range, and output, by means of a designated external device, a fatigue notification indicating a fatigued state if the fatigue data exceeds a designated third range. Other various embodiments identified in the description are possible.

First claim

The invention claimed is:

1. A wearable electronic device configured to be worn on a user comprising:
a display;
an accelerometer;
a heart rate sensor;
a fatigue sensor; and
a processor,
wherein the processor is configured to:
sense movement of the wearable electronic device using the accelerometer;
when the sensed movement exceeds a threshold movement, sense a heart rate of the user using the heart rate sensor;
when the sensed heart rate exceeds a threshold heart rate, sense fatigue of the user based on electric current detected by using the fatigue sensor; and
when the sensed fatigue exceeds a first threshold fatigue, output a fatigue notification on the display, the fatigue notification indicating a fatigue state.

2. The wearable electronic device of claim 1 , wherein
the processor is further configured to:
continue monitoring the movement of the wearable device using the accelerometer when the sensed movement is equal to or less than the threshold heart rate.

3. The wearable electronic device of claim 2 , wherein the threshold heart rate is set based on at least one of an age, gender, genetic characteristics or activity information of the user.

4. The wearable electronic device of claim 2 , wherein the processor is further configured to:
determine an exercise type and an exercise time based on the sensed movement of the wearable electronic device.

5. The wearable electronic device of claim 4 , wherein the processor is further configured to:
calculate calories burned based on the determined exercise type and the determined exercise time; and
output the calculated calories burned on the display.

6. The wearable electronic device of claim 1 , wherein the fatigue sensor is configured to, when the sensed heart rate exceeds the threshold heart rate:
apply a specified voltage between a first electrode of the fatigue sensor and a second electrode of the fatigue sensor, the second electrode including a catalyst layer for reaction with lactic acid;
measure an amount of current between the first electrode and the second electrode; and
measure lactic acid concentration based on the amount of current.

7. The wearable electronic device of claim 1 , wherein the heart rate sensor includes at least one of a photoplethysmography (PPG) sensor or an electrocardiography (ECG) sensor.

8. A method of providing a fatigue notification by a wearable electronic device, the method comprising:
sensing movement of the wearable electronic device using an accelerometer of the wearable electronic device;
when the sensed movement exceeds a threshold movement, sensing a heart rate of a user of the wearable electronic device using a heart rate sensor of the wearable electronic device;
when the sensed heart rate exceeds a threshold heart rate, sensing fatigue of the user based on electric current detected by using a fatigue sensor of the wearable electronic device; and
when the sensed fatigue exceeds a first threshold fatigue, outputting a fatigue notification on a display of the wearable electronic device, the fatigue notification indicating a fatigue state.

9. The method of providing a fatigue notification of claim 8 , wherein the threshold heart rate is set based on at least one of an age, gender, genetic characteristics, or activity information of the user.

10. The method of providing a fatigue notification of claim 8 , further comprising:
determining an exercise type and an exercise time based on the sensed movement of the wearable electronic device.

11. The method of providing a fatigue notification of claim 10 , further comprising:
calculating calories burned based on the determined exercise type and the determined exercise time; and
outputting the calculated calories burned on the display.
