The aim of the invention is to provide a device for inputting text by a single actuation of a key on a numerical keypad and a method for processing input impulses for portable electronic devices comprising a display. To achieve this, sensors that measure the finger position of the operator on the key are located under each key and control electronics, which evaluate said position and assign the latter to one of the possible input options, are provided. During the actuation of a key on the keypad, a list containing the possible input options appears on the display and a single input option that corresponds with each respective actuation position is highlighted by a block. The actuation position can be modified during actuation, thus displacing the highlighting at will onto the displayed input options. When the respective key is released, the input option that was last highlighted is registered as the keyed input.
