Method for measuring biological signal and wearable electronic device for the same

Abstract

According to an embodiment of the present disclosure, there is a wearable electronic device, comprising: a first sensor configured to sense a movement of the electronic device; a second sensor configured to sense a biological signal for a user wearing the electronic device; and a processor configured to compute a movement value of the electronic device using the first sensor, to detect a resting state when the movement value lasts within a predetermined first threshold range during a first time period, and to configure biological information of the user based on a biological signal measured after detection of the resting state.

What is claimed is: 
     
         1 . A wearable electronic device, comprising:
 a first sensor configured to sense a movement of the electronic device;   a second sensor configured to sense a biological signal of a user wearing the electronic device; and   a processor configured to receive, via the first sensor, information relating to the movement of the electronic device, and to determine a pulse rate of the user based on the biological signal at a first time if a movement of the electronic device is less than a predetermined first threshold range during a first time period before the first time based on the information received from the first sensor.   
     
     
         2 . The wearable electronic device of  claim 1 , wherein the electronic device comprises a wrist watch, and the processor is configured to determine whether the wrist watch is currently being worn by a user. 
     
     
         3 . The wearable electronic device of  claim 1 , wherein, if a movement of the electronic device is greater than the first threshold range during the first time period, the processor is configured to determine a pulse rate of the user at a later time after the first time. 
     
     
         4 . The wearable electronic device of  claim 1 , wherein the processor is configured to activate the second sensor to sense the biological signal if a movement of the electronic device is less than a predetermined first threshold range during a first time period. 
     
     
         5 . A method for measuring biological information using a wearable electronic device, the method comprising:
 receiving information relating to a movement of the electronic device;   determining whether a movement of the electronic device is less than a predetermined first threshold range during a first time period based on the information relating to a movement of the electronic device;   receiving a biological signal of a user wearing the electronic device; and   determining a pulse rate of the user based on the biological signal at a first time if a movement of the electronic device is less than a predetermined first threshold range during a first time period before the first time based on the information relating to a movement of the electronic device.   
     
     
         6 . The method of  claim 5 , wherein the electronic device comprises a wrist watch, and the method further comprising determining whether the wrist watch is currently being worn by a user. 
     
     
         7 . The method of  claim 5 , further comprising if a movement of the electronic device is greater than the first threshold range during the first time period, determining a pulse rate of the user at a later time after the first time. 
     
     
         8 . The method of  claim 5 , wherein receiving the biological signal of the user is initiated if a movement of the electronic device is less than a predetermined first threshold range during a first time period.
