Abstract:
1. A method for display and input, of information on a technical medical device haying at least one touchscreen, said method comprising: determining with two redundant sensors a position of a finger pressure on the touchscreen, at least one of the two redundant sensors including a plurality of piezoelectric elements; detecting with a control unit signals of the two redundant sensors that determine the position of the finger pressure on the touchscreen; determining with the control unit whether there has been an unintentional finger pressure on the touchscreen when the signal of at least one of the two redundant sensors is too low; determining whether a visual display of the touchscreen is functioning; and if the visual display of the touchscreen is determined to not be functioning, controlling the plurality of piezoelectric elements such that partial areas of the touchscreen have different tactile properties.
