Abstract: An information processing system has a display monitor and a user-interface for text entry. The display monitor presents the set of alphanumerical characters in a spatial configuration of three parallel horizontal rows or three parallel vertical columns. The “left”-button and the “right” button of the directional buttons of the user-interface control the selection of a group of alphanumerical characters, one of each of the three parallel arrays and positioned in the same column. The “up”-button and the “down”-button of the directional buttons and the “OK”-button, sitting in between, are used to select a specific one of the alphanumerical characters from the selected group.

Abstract: A device for inputting control commands has an at least in parts light-transmitting surface and includes an apparatus for projecting a number of graphic symbols through respective symbol areas (3,4) of the surface, a control command being associated with each graphic symbol. The apparatus includes a lighting arrangement (10;16;22) for selectively illuminating symbol areas (3,4) from within the device through at least one screen (12;17;24) patterned simultaneously in accordance with a plurality of the graphic symbols. The at least in parts light-transmitting surface includes at least one area (2) corresponding to a key, each area (2) corresponding to a key encompassing at least one of the symbol areas (3,4). The device for inputting control commands further includes an input device (13;20;25) for detecting selection of an area (2) corresponding to a key by a body.
