A processing system adapted for use in a gaming environment is configured to detect when a user might accidentally drop an input device, such as a handheld game controller. The processing system includes an input device, a processing unit and a warning unit. The input device has one or more pressure sensors operable to sense pressure inputs from a user. The processing unit is operable to identify an imminent dropping of the input device from measurements obtained by the pressure sensors. And the warning unit is operable to provide a warning to the user when the processing unit identifies an imminent drop of the input device.
