Abstract
A display screen, for example a touch-sensitive screen, provides a first type of audible output when a region of the display screen is indicated for possible input, and a second type of audible output when an input is made at a region of the display screen. The display screen may be provided in a communications device such as a mobile phone, with different regions of the screen representing the numeric keys of the phone. Without looking at the screen, the user can then use the audible output indicating that he is touching a region representing a key, to determine the position of his finger on the screen
