Abstract: A controller for use in a device which comprises at least two force sensors in a given arrangement, the controller operable, based on input sensor signals derived from the force sensors, to carry out an arrangement-related operation in which an output sensor signal is generated based on at least two said input sensor signals and the arrangement of the force sensors in the device so that the output sensor signal is dependent on said arrangement.

Abstract: A force sensing system for determining if a user input has occurred, the system comprising: an input channel, to receive an input from at least one force sensor; an activity detection stage, to monitor an activity level of the input from the at least one force sensor and, responsive to an activity level which may be indicative of a user input being reached, to generate an indication that an activity has occurred at the force sensor; and an event detection stage to receive said indication, and to determine if a user input has occurred based on the received input from the at least one force sensor.
