Methods and apparatuses for controlling operation of a vibrational output system and/or operation of an input sensor system

A device comprising:

• an input sensor system;
• a vibrational output system;
• a controller configured to control operation of the vibrational output system and/or the input sensor system, wherein the controller comprises:
• an input configured to receive an indication of vibration;
• and
• an adjustment module configured to adjust operation of the vibrational output system and/or operation of the input sensor system based on the indication to reduce an interference expected to be caused by the vibration;
• wherein the adjustment module is configured to adjust a drive signal or power level of the input sensor system in response to the indication of vibration.

An integrated circuit for use in a device comprising an input sensor system and a vibrational output system, the integrated circuit comprising a controller configured to control operation of the vibrational output system and/or the input sensor system, wherein the controller comprises:

• an input configured to receive an indication of vibration;
• and
• an adjustment module configured to adjust operation of the vibrational output system and/or operation of the input sensor system based on the indication of vibration;
• wherein the adjustment module is configured to adjust a drive signal or power level of the input sensor system in response to the indication of vibration.

A method for use in a device comprising a vibrational output system and an input sensor system for controlling operation of the vibrational output system and/or the input sensor system, the method comprising:

• receiving an indication of vibration;
• and
• adjusting operation of the vibrational output system and/or operation of the input sensor system based on the indication of vibration to reduce an interference expected to be caused by the vibration on the input sensor system;
• wherein adjusting operation of the input sensor system comprises adjusting a drive signal or power level of the input sensor system in response to the indication of vibration.
