Abstract: A method of measuring the aura of a human body is provided wherein the method comprises putting a system for measuring aura of a human body to an initial status by first selecting from a program a mode of operating said system, wherein the mode comprises a camera-using mode and a camera non-using mode. The system is capable of measuring physiological signals of a human body. According to the method, a timer function is selected on the system to use a timer through a program that delays the reading of the physiological signals of the person tested for about 5-10 seconds, two palms are contacted on aura sensing part for measuring physiological signals of a human body, the physiological signals of the human body are read from the sensors with the system, and the aura image of the physiological signals is displayed on a monitor.
