A touch sensitive method for simulating a stylus as a joystick, comprises: maintaining a mode parameter for recording an operating mode of the stylus; detecting, by a touch panel, a position, an axial direction and a tilt angle of the stylus with respect to the touch panel; and when the mode parameter indicates a joystick mode, converting the axial direction and the tilt angle into a first-axis tilt angle and a second-axis tilt angle and transmitting the first-axis tilt angle and the second-axis tilt angle to an application via a joystick driver, when the mode parameter indicates a stylus mode, transmitting the position to a touch sensitive driver, wherein the joystick driver, the touch sensitive driver and the application are executed under an operating system environment run by a central processing unit of a host.
