ControllerAxispollingDeadZone Property

The polling dead zone used when polling the axis. In order for the axis to be detected when polling, the change in absolute value of the axis over the polling period must be greater than this amount. Do not set this value extremely low or noisy axes will be detected when at rest. A value of -1 means the default global polling dead zone will be used instead. [Default = -1]
