1. A smart watch, comprising:
a dial;
a watchband connected to the dial; and
a processing device disposed on the dial or inside the watchband; wherein
the processing device comprises:
an optical emitter configured to emit light;
an optical receiver configured to receive reflected light, the reflected light being generated by the light emitted by the optical emitter irradiating a skin for conversion into an electrical signal;
a processor connected to the optical emitter and the optical receiver, respectively, configured to process the electrical signal to obtain heart rate information of a user;
an accelerometer sensor configured to detect and obtain motion information of the user, wherein the motion information comprises at least one of: direction information of the user, location information of the user, and speed variation rate of the user; and
a gyroscope sensor configured to detect and obtain angular velocity information of the user;
wherein the processor is connected to the accelerometer sensor and the gyroscope sensor, respectively;
the accelerometer sensor is configured to send the motion information to the processor;
the gyroscope sensor is configured to send the angular velocity information to the processor; and
the processor is configured to:
receive the motion information and the angular velocity information;
generate motion-tolerant heart rate information by combining the motion information and the angular velocity information with the heart rate information; and
control the smart watch to send a second reminder message in response to the motion-tolerant heart rate information exceeding a first threshold; or,
control the smart watch to send a second reminder message in response to the motion-tolerant heart rate information exceeding a second threshold for a predetermined period of time, wherein the first threshold and the second threshold are the same or different, and the second reminder message is configured for reminding the user of the motion-tolerant heart rate information.
