A method for automatic switching between a cursor controller and a keyboard of depressible touch panels includes at least the following procedures: 1. setting operation modes for a touch panel in a cursor controller state and a keyboard state that are switchable alternately; 2. detecting sliding (movement) of a user's finger on the touch panel in the keyboard state and switching to the cursor controller state when the detected sliding reaches a set value; 3. detecting all depressing signals in the keyboard state and entering designated characters of depressing locations and maintaining the keyboard state; 4. detecting the touch panel depressed by the user's finger in a set condition in the cursor controller state and switching to the keyboard state; 5. detecting the sliding of the user's finger in the cursor controller state and moving the cursor in a corresponding manner on a screen and maintaining the cursor controller state. By means of the procedures set forth above user's requirements can be judged automatically, and instant switching of the touch panel between the keyboard state and cursor controller state can be accomplished to enable users to perform various types of input operations and function execution.
