Abstract: An input system having at least one sensor board, at least one recording medium and at least one input device/stylus. The at least one sensor board is divided into at least two virtual sub-boards or the at least one sensor board is in the form of two separate sensor boards. The two sensor boards have, on at least one side edge, a structure for mutual fixing. A multi-page recording medium is arranged over the at least one sensor board. The at least one input device/stylus has an analogue application function. The at least one input device/stylus has a digital input function/signal function for sensor boards.
