A notification control system (NCS) is configured to coordinate the delivery of notifications issued from a set of devices to the driver of a vehicle. The NCS registers all interactive devices residing in a vehicle and causes those devices to conform to specific directives generated by the NCS. The NCS analyzes and predicts the cognitive and emotional load on the driver and also estimates the cognitive and emotional impact on the driver potentially caused by any incoming notifications. The NCS then coordinates the delivery of notifications to the driver in a manner that avoids overwhelming the cognitive and/or emotional capacity of the driver. Accordingly, the NCS may avoid situations where device notifications cause the driver to unsafely divert attention away from driving.
