Title
(EN) Systems and methods for mitigating vigilance decrement while maintaining readiness using augmented reality in a vehicle
Abstract
(EN)

System, methods, and other embodiments described herein relate to mitigating vigilance decrement of a vehicle operator. In one embodiment, a method includes monitoring the operator by collecting operator state information using at least one sensor of the vehicle. The method includes computing an engagement level of the operator according to a vigilance model and the operator state information to characterize an extent of vigilance decrement presently experienced by the operator. The method includes rendering, on an augmented reality (AR) display, at least one graphical element as a function of the engagement level to induce the operator to maintain vigilance with respect to operation of the vehicle and a present operating environment around the vehicle.
