An inertia sensing module is connected to a portable electronic device. The inertia sensing module includes an accelerometer unit for generating at least one of acceleration sensing signals ax, ay, az corresponding to the directions of X, Y, Z respectively; a gyroscope unit for generating at least one of angular rate sensing signals ωx, ωy, ωz corresponding to the axes of X, Y, Z respectively; and a connector module having a plug that is inserted into a docking connector of the portable electronic device. With the inertia sensing module being connected to or disconnected from the portable electronic device, a user can control a specific cursor or graphic user interface on a picture of an electronic game player via his/her own motions.
