A method for controlling a graphical display receives a user input at a touch-sensitive user interface. Responsive to receiving that user input, a user is automatically recognized from biometric data gathered at that touch-sensitive user interface, such as by comparison to a locally stored database of authorized users. A visual cursor at a graphical display is then automatically activated. The visual cursor is removed from the graphical display when the user input is no longer received at the touch-sensitive user interface. So long as the visual cursor is not removed and after user authentication, movement of the visual cursor at the graphical display is made to correspond with movement sensed at the touch-sensitive user interface.
