The method includes acquiring the physiological signal of a user, and controlling a haptic feedback device to activate to generate and output a haptic feedback signal in response to the physiological signal and starting a first timer simultaneously.

Abstract: Provided are a tracking method and apparatus of an exercise heart rate, a device and a storage medium. The method includes: if the user heart rate currently detected by a photoelectric heart rate device does not meet a preset heart rate standard, invoking a pre-established target model equation reflecting the relationship between a user heart rate and a user pace; and inputting the current real-time pace of a user into the target model equation to obtain the current real-time heart rate of the user. In the technical solutions, when the user heart rate currently detected by the photoelectric heart rate device does not meet the preset heart rate standard, the current real-time pace of the user is directly input into the pre-established target model equation reflecting the relationship between the user heart rate and the user pace to obtain the current real-time heart rate of the user.
