A user input as shown in Figure 1, having a first mode of operation relating to the entry of a command is indicated on a display device (108) prior to the actual execution of the command, afterwhich a second mode of operation may be entered wherein the command is actually executed using the displayed information (118) for confirmation purposes. In a preferred embodiment, the user input device takes the form of a hand-held remote-control unit (104) and the display device is a television monitor. The display may show a textual information relating to the pushbutton (112) in closest proximity to the user's finger or, alternatively, the display may show a graphical representation of at least a portion of the keypad, along with an icon that moves relative to the graphical display in relation to movements made by the user. |
