The concept of the second order change detection, which allows one to discriminate the local (most recent) change in an image, such as blink of the eyes, from the global (long lasting) change, such as the motion of head, is introduced. This concept sets the base for designing complete a face operated control system, in which, using the analogy with mouse, "pointing" is performed by nose and "clicking" is performed by double-blinking of the eyes. The implemen tation of such a system is described.
