Method and system for calibrating human state sensor

There is provided a method and system for calibrating a human state sensor, the method comprising: detecting a plurality of output values of the sensor, the output values being indicative of a mental and/or physiological state of a user; determining a boundary output value based on the detected plurality of output values, wherein a predetermined portion of the detected output values is higher or lower than the boundary output value; a threshold output value for the sensor is determined based on the boundary output value. 提供了一种用于校准人类状态传感器的方法和系统，所述方法包括：检测所述传感器的多个输出值，所述输出值指示用户的精神和/或生理状态；基于所述检测到的多个输出值来确定边界输出值，其中所述检测到的输出值的预定部分高于或低于所述边界输出值；基于所述边界输出值来确定所述传感器的阈值输出值。
