Abstract
Methods and systems for reducing driver distraction and situation non-awareness related to a dialog of an automated dialog system in a vehicle. For a dialog policy learning session, driver distraction is introduced as an input into a penalty assigner that assesses dialog quality, and dialog acts are extended to include dialogs and dialog act presentation styles which reduce driver workload related to dialogs. The automated dialog system policy is developed during the learning process by optimizing the penalties, so that automated dialog workload is reduced in response to increased workload or anticipated workload on the driver. Methods and systems are presented for responding to both actual workload in regular vehicles as well as anticipated workload in autonomous vehicles.
