Patent ID: 7352364

Claim:
A method for toggling between touch control operation modes, being applied in an electronic data processing device with a touch control device and providing a switch of its operation between a first coordinate operation mode and a second coordinate operation mode to input by using said touch control device, and said method comprising the steps of: (A) setting a predetermine area of said touch control device y a controller of said touch control device as a switching mode area; (B) determining by said controller whether or not a received position signal to act as an instruction for toggling between said first coordinate operation mode and said second coordinate operation mode, wherein said controller determines a received position signal until all position signals are received, if at least one among said all position signals is not located in said switching mode area, said determination step is set as false, and said determination is used to confirm a normal operation of said switching operation mode and prevent toggling said operation modes by mistake; and (C) setting the current operation mode to another operation mode by said touch control device, if Step (B) is determined as true.
