[0053] In some embodiments, the first controller is configured to determine the third emotion code as the target emotion code when the power ratio is less than a second power threshold. For example, if the second power threshold is 0.8 and the power ratio is 0.7, the first controller is configured to determine the third emotion code "0x02" as the target emotion code.

[0054] In some embodiments, the second controller is specifically used for: If the target emotion code is the first emotion code, the first color temperature is determined as the target color temperature; or If the target emotion code is the second emotion code, then the second color temperature is determined as the target color temperature; or If the target emotion code is the third emotion code, then the third color temperature is determined as the target color temperature.

This application does not impose any specific limitations on this.

[0058] In practice, the heart rate acquisition device may also include a noise amplifier to amplify the PPG signal.

[0059] In actual implementation, the heart rate acquisition device may also include an analog-to-digital converter (ADC), which can convert the acquired heart rate signal into heart rate data based on the analog-to-digital converter.

[0060] Step 320: Based on heart rate data, determine the target color temperature, and control the emission of the light-emitting array based on the target color temperature to regulate the user's cortisol.

[0061] In some embodiments, the control unit may store a heart rate data-color temperature curve, which includes several heart rate data points and the color temperature corresponding to each heart rate data point. The color temperature corresponding to the heart rate data in the heart rate data-color temperature curve can be determined as the target color temperature.

[0068] In some embodiments, the power ratio can be obtained based on the following formula: ; Where R represents the power ratio, LF represents low-frequency power, and HF represents high-frequency power.

[0069] In some instances, when the power ratio is greater than a first power threshold, the first emotion code is identified as the target emotion code; the first emotion code represents an anxious emotional state. or If the power ratio is less than or equal to the first power threshold and greater than or equal to the second power threshold, the second emotion code is determined as the target emotion code; if the second power threshold is less than the first power threshold, the second emotion code represents a normal emotional state. or If the power ratio is less than the second power threshold, the third emotion code is determined as the target emotion code; the third emotion code represents a relaxed emotional state.

[0070] In actual execution, both the first power threshold and the second power threshold are preset values.

[0071] In some embodiments, the first emotion code can be determined as the target emotion code if the power ratio is greater than a first power threshold. For example, if the first power threshold is 2.5 and the power ratio is 2.8, the first controller is used to determine the first emotion code "0x01" as the target emotion code.

[0072] In some embodiments, the second emotion code can be determined as the target emotion code if the power ratio is less than or equal to a first power threshold and greater than or equal to a second power threshold. For example, if the first power threshold is 2.5, the second power threshold is 0.8, and the power ratio is 1.7, the second emotion code "0x00" can be determined as the target emotion code.

[0073] In some embodiments, the third emotion code can be determined as the target emotion code if the power ratio is less than a second power threshold. For example, if the second power threshold is 0.8 and the power ratio is 0.7, the third emotion code "0x02" can be determined as the target emotion code.

[0074] According to the desktop color temperature control method of this application embodiment, the control unit determines the target color temperature based on the heart rate data of the user's sympathetic-parasympathetic state, and controls the light emission array to emit light based on the target color temperature, so as to achieve the purpose of adjusting the desktop color temperature based on the user's emotional state, further regulating the user's cortisol and improving the user experience.

[0075] In some embodiments, when the target emotion code is a first emotion code, the first color temperature is determined as the target color temperature; or If the target emotion code is the second emotion code, then the second color temperature is determined as the target color temperature; or If the target emotion code is the third emotion code, then the third color temperature is determined as the target color temperature.
