Abstract
A programmatic organisation method, or concept, for augmented use of a standardized keyboard, capable of detecting depression/touching of single keys as well as simultaneously depressed/touched combinations of keys. According to the invention, simultaneous depression/touching of two or more adjacently or non-adjacently located keys of said keyboard is decoded as a predetermined character, symbol, note, action etc., whereby the input capability of the keyboard is considerably enhanced. Advantageously are predetermined functions, e.g. a 'shift' ('CAP') or num lock function by predetermined single keys or predetermined key combinations, i.e. the input capability can thus be enhanced even further, each such function resulting in a new and independent input capability The keyboard may advantageously be a conventional numerical 3×4 keyboard.
