Patent number: 11617539Abstract: Methods and apparatuses are provided for measuring a biometric signal by an electronic device. An object having an animation effect for inhalation and exhalation is displayed. The animation effect includes the object being expanded to guide the inhalation of a user and the object being contracted to guide exhalation of the user. A sensor unit obtains at least one biometric signal related to a heart rate of the user while the object is displayed. A motion of the electronic device is detected having a strength that is greater than or equal to a threshold strength. Based on the motion ceasing before exceeding a predetermined time, display of the object and obtaining of the at least one biometric signal is continued. Based on the motion lasting longer than or equal to the predetermined time, the obtaining of the at least one biometric signal and the displaying of the object is terminated.Type: GrantFiled: October 19, 2021Date of Patent: April 4, 2023Inventors: Hyun-Jae Baek, Jung-Taek Oh, Jae-Geol Cho, Chul-Ho Cho, Gun-Woo Jin
