A human negligence warning method based on augmented reality includes steps of: using a smart wearable device to photograph multiple physical operation elements of an electronic apparatus and obtain interface depth data; performing spatial position calculations according to the interface depth data and setting corresponding wrapping geometry elements between the physical operation elements and the smart wearable device to cover the physical operation elements, respectively; photographing a hand of a wearer wearing the smart wearable device to obtain a gesture and a spatial position of the hand; and judging whether the hand touches one of the wrapping geometry elements according to the gesture and the spatial position, and further judging whether a procedure corresponding to the physical operation element is correct if yes. If the procedure is not, then a warning operation is performed to avoid human negligence. |
