D' aquesta manera, quan es facin petits moviments amb el dispositiu físic (pex;, un ratolí), encara mantindreu un control fi del cursor a la pantalla, mentre que moviments majors el mouran ràpidament a diferents àrees de la pantalla.
Thus, when you make small movements with the physical device (eg; mouse), you still have fine control of the mouse pointer on the screen, whereas larger movements of the physical device will move the mouse pointer rapidly to different areas on the screen.
