1. A controller for a device which comprises at least two force sensors in a given arrangement, the controller operable, based on input sensor signals derived from the at least two force sensors, to carry out a localisation operation in which an output sensor signal is generated based on a given weighting associated with at least two said input sensor signals and defining a location of interest relative to locations of the at least two force sensors so that the output sensor signal of the localisation operation is representative of the location of interest, the input sensor signals being input sensor signals of the localisation operation, wherein the localisation operation comprises, in association with at least one of its output sensor signals, calculation of a further output sensor signal as a function of a first ratio of the input sensor signals concerned to one another and a second ratio defining the given weighting concerned.
