A smart walking cane may include a smart cane, a smart device, and a smart software. The smart cane has a cane body, and a cane handle is formed on the top of the cane body to be held by the user. The cane body comprises a nine-axis inertial sensor, a pressure sensor, and a photoelectric sensor. The nine-axis inertial sensor has a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer, and the three-axis accelerometer is used to detect the gravitational acceleration of the smart cane along the X, Y, and Z axes, allowing for the detection of movement speed, step count, and whether the user's hand has tremors while using the smart cane.
