An alerter augmentation system includes one or more processors that determine an alertness of an operator of a vehicle system. The one or more processors also generate operator input requests that are separated in time by a temporal delay. These input requests seek responses or action by the operator in an attempt to keep or make the operator alert. The one or more processors change one or more of the temporal delay between the input requests and/or a type of the input requests that are generated based at least in part on the alertness of the operator that is determined.
