1. A method for detecting abnormal device operation, suitable for an electronic device connected to a movable input device, the method comprising:
obtaining action data of the movable input device, wherein the action data comprises a plurality of action events, and each of the action events comprises a time stamp of the movable input device;
generating a plurality of absolute coordinates corresponding to the action data based on the action events;
estimating a plurality of speed vectors corresponding to the action data based on the absolute coordinates and the time stamp of each of the action events;
estimating a plurality of acceleration vectors corresponding to the action data based on the speed vectors and the time stamp of each of the action events; and
estimating a probability of the action data corresponding to abnormal operation based on the speed vectors and the acceleration vectors.
