An electronic device is provided that includes a display, a biometric sensor, a motion sensor, a communication circuit configured to receive a signal for obtaining information related to a location of the electronic device, and a processor electrically connected with the display, the biometric sensor, the motion sensor, and the communication circuit, wherein the processor is configured to identify repeated activities related to the user, which follow a lapse of time, based on motion information obtained according to the lapse of time by using the motion sensor and location information obtained according to the lapse of time by using the communication module, calculate a stress index of the user corresponding to the repeated activities based on biometric information obtained by using the biometric sensor, and provide at least one activity of the repeated activities and a stress index corresponding to the at least one activity.

Electronic device and method for providing stress index corresponding to activity of user

This invention, which comprises a cuff, an exhaust portion, a pressure sensor, an A/D converter, a microcomputer, a display, and an operation portion, initially determines the maximum pulse wave amplitude by comparing the size of each pulse wave, and it then determines the maximum pulse wave amplitude by comparing the sizes of the values obtained by totalling each pulse wave amplitude along with its preceding and subsequent pulse wave amplitudes, and it finally determines the maximum pulse wave amplitude by evaluating whether the different value between each preceding and each subsequent pulse wave amplitudes which occur after the maximum pulse wave amplitude has a negative(-) sign, thereby eliminating erroneous calculations caused by oscillation noise interference.
