Abstract
A driver attention system is configured to determine a drowsiness level of a driver of a vehicle by means of data provided by a monitoring unit configured to determine one or more driver parameters based on the current drowsiness level, determine a current driver focus level and an estimated time of remaining driver focus level, wherein the driver focus level is inversely proportional to the drowsiness level, and determine an estimated remaining travel time until a desired destination is reached by means of data provided by a navigation system. During selected conditions, a binaural beat at 20 Hz or higher is generated via at least two first loudspeakers of an audio system of the vehicle, wherein the binaural beat is audible for the driver.
