Abstract: A method for operating a driver assistance system for a motor vehicle, a viewing direction of a driver of the motor vehicle being monitored and compared to at least one setpoint value. The at least one setpoint value is determined as a function of the course of a route, and an attention value is determined for the driver as a function of the comparison.

Abstract: A method for avoiding a tunnel vision of a motor vehicle driver includes detecting an instantaneous viewing direction of the driver; comparing the instantaneous viewing direction with at least one previous viewing direction; detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached; and stimulating the motor vehicle driver to avoid the tunnel vision. A device for avoiding a tunnel vision of the driver includes a camera for detecting an instantaneous viewing direction of the motor vehicle driver; a control unit for comparing the instantaneous viewing direction with at least one previous viewing direction and for detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached, and a device for stimulating the motor vehicle driver to avoid the tunnel vision.

Abstract: A method for detecting the viewing direction of a person having a visual aid includes providing at least one optical property of a visual aid of the person, observing at least one eye of the person, and correcting data ascertained from the observation based on the at least one optical property of the visual aid. An apparatus designed to detect the viewing direction of a person includes an observation device set up to observe at least one eye of the person, a data record containing at least one optical property of a visual aid of the person, and a computing device equipped to correct the observation based on the data record.

Abstract: In a method for detecting the face of a driver of a motor vehicle having a camera, in order to ensure that an unfavorable posture of the driver or an unfavorable position of the steering wheel or of the driver's seat of the motor vehicle does not prevent recognition of the face using the camera, provision is made that a positioning signal for the steering wheel, for the driver's seat, or for a pedal is generated if the face is not detectable in the image data.

Abstract: A navigation system is provided with various interlinked facilities, including a user I/O facility, a route planning facility and a position determining facility. In particular, the navigation system is arranged to physically interface to a data communication facility pertaining to organizer device. An embodiment of such system includes the navigation system arranged to signal actual route data to said organizer device for consideration in a preexistent timetable or diary context. Such system is preferably characterized in that said organizer device is arranged to signal actual diary or timetable data to said navigation system for consideration in a preexistent or future route scheme context.

Abstract: In a method for displaying primary and secondary information in a motor vehicle by reproducing symbols on a display, the symbols are shown with different brightnesses according to their importance. Their brightness is changed as the importance of the information changes.

Abstract: In an automotive vehicle a road map is displayed that features an indicator of the actual vehicle orientation and position. Such orientation and position are on a long term basis maintained steady with respect to a display field. In particular, a geographical window is set up regarding actual movements of the vehicle. It is checked whether the vehicle remains inside or outside of the window. If inside, the movements are displayed while at least partially suppressing the maintaining. If outside, the movements are displayed while substantially upholding such maintaining.

Abstract: A device for unwinding elongated material from a coil which includes a plate which is placed on top of the coil, with the plate including a rotatable guide means for guiding unwound material, and at least two elongated arcuate members which extend into the coil interior and define a cylindrically shaped shell. The arcuate members are pivotally mounted to the plate, and are provided with a means which exerts a force against the arcuate members to press the arcuate members against the coil interior to hold the interior windings as the coil is unwound.
