Abstract: A method of changing the identified type of a touching object is provided. The touching object is on a touch pad. The method includes the following steps: (A) when the type of the touching object is determined as a palm, determining the type of the touching object again; (B) when the type of the touching object is determined as a finger in step (A), informing the operating system that the touching object has left the touch pad when the touching object does not leave the touch pad; and (C) after step (B) is done, informing the operating system that the type of the touching object is a finger.
