1. A controller for controlling an operation of a vibrational output system and/or an operation of an input sensor system, wherein the controller is for use in a device comprising the vibrational output system and the input sensor system, the controller comprising:
an input configured to receive an indication of activation or de-activation of an output of the vibrational output system; and
an adjustment module configured to adjust the operation of the vibrational output system and/or the operation of the input sensor system based on the indication to reduce an interference expected to be caused by the output of the vibrational output system on the input sensory system, wherein the adjustment module is configured to, responsive to the indication indicating activation of the output of the vibrational output system, adjust the operation of the input sensor system such that the input sensor system performs sensing only during one or more time intervals during which an output signal being output to the vibrational output system has a vibrational amplitude below a predetermined threshold amplitude.
