<P>PROBLEM TO BE SOLVED: To provide a method mounted in a computer for setting and operating a driver assistance system. <P>SOLUTION: The method includes steps of: visually sensing an environment of a vehicle; sensing at least one change rate of a parameter which represents the state of the vehicle and can be influenced by a driver operating a man/machine interface of the vehicle; and constituting information collected by the visual sensing by classifying at least one sensed change rate into various categories so as to find a visual characteristic associated with a specific category of the sensed change rate, i.e., associated with a specific behavior of the driver. <P>COPYRIGHT: (C)2011,JPO&INPIT
