A method of recording measurement data for characterizing a response of a given type of
device to an applied force, 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≥
1, 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: for a …
