Abstract
Methods and apparatus to monitor an activity level of a driver are disclosed. An example method includes receiving, at a processor, eye movement data from a sensor monitoring eye movements of a driver of a vehicle. The method includes calculating, via the processor, an eye movement activity index using a substantially real-time recursive analysis of the eye movement data. The method further includes calculating, via the processor, a low activity indicator for the driver based on the eye movement activity index. The method also includes executing a task based on the low activity indicator.
