<p>The method allows handicapped users, in particular users with impaired vision, to control an apparatus (20), such as a fare collection apparatus of a transportation network, by means of a system interface comprising a display unit (1), preferably a flat panel display, enhanced with touch screen functionality, on which for each transaction to be executed one or more pages with selectable fields are sequentially displayed. The system interface can be operated at least in one mode, designed for handicapped users in such a way, that when a user touches the screen (1-1, 1-2, ...) of the display unit (1) with one hand and subsequently moves on the the screen (1-1; 1-2; ...), the system interface acoustically announces and/or optically displays the contents of the input fields visited on the screen (1-1, 1-2, ...) and accepts a field selection when the user lifts his hand or an object held therein from the currently visited input field.</p> |
