Abstract
A method and a device for presenting digits, letters and other characters uses a number of signals for representing each character. Said signals are combined with signals from manually operable touch point electrodes. When predetermined electrodes are operated simultaneously with reception of a predetermind character signal or character signal combination, the combining means activates an acoustic, visual or tactile output signal so that a character representing signal code can be recognized. A code conversion between the input signals and the output signals can be provided so that the output character is presented in a code with fewer elements than the input character.
