Abstract
An apparatus and method are disclosed for real-time assessment of driver workload by a vehicle device. To determine driver workload, the system monitors the driver interaction with the vehicle device. The driver interaction is then used to determine an estimated driver workload based on the driver interaction. In one embodiment, the vehicle device has one or more buttons configured to be pressed by the driver and each of the one or more buttons has an assigned driver workload value. The system sums the workload value of the buttons pressed by the driver over a moving time window to determine the estimated driver workload.
