1. A computer-implemented method of generating a configuration definition for configuring a given type of device for a given use case defined by a use-case definition, the given type defining devices of that type as comprising a defined arrangement of a surface and N force sensors of the device concerned, where N≥2, each force sensor configured to output a sensor signal, wherein in the defined arrangement the N force sensors are operatively coupled to a defined input region of the surface so as to sense a force applied to that input region, the method comprising:
recording measurement data for devices of the given type by:
for a specimen device of the given type, performing at least one measurement procedure, each measurement procedure comprising at least one measurement operation, each measurement operation comprising applying a defined force at a corresponding location on the input region of the device concerned and recording measurement data for that device and location based on the sensor signals of the N force sensors of that device,
wherein each measurement procedure comprises P measurement operations, where P≥2, the respective locations for the P measurement operations on the input region of the device concerned being different from one another,
wherein the corresponding locations for the P measurement operations are distributed across the input region of the device concerned, and
wherein the method comprises performing each measurement procedure using a computer-controlled machine;
generating a characterization definition for devices of that type based on the recorded measurement data, wherein the characterization definition defines a response of devices of the given type to an applied force, and wherein generating the characterization definition comprises, based on the recorded measurement data, generating a characterization function per force sensor of the N force sensors, each characterization function defining a relationship between input region location and sensitivity of the force sensor concerned; and
generating the configuration definition based on the characterization definition and the use-case definition,
wherein generating the configuration definition comprises generating cross-talk information by determining from the characterization definition, for at least one of the N force sensors, a magnitude of the sensor signal for each other force sensor of the N force sensors at an input region location where the sensor signal for the force sensor concerned has its maximum value.
