Abstract
A method for providing a driver with a warning includes determining that a vehicle is being operated in a manner that fails to comply with a constraint imposed on motion of vehicles on a section of a road, determining that a driver of the vehicle is gazing in a non-neutral direction, based on having done so, selecting a level of obtrusiveness for the warning message, and outputting the warning message at that level.
Claims20
A method comprising determining that a vehicle is being operated in a manner that fails to comply with a constraint imposed on motion of vehicles on a section of a road, determining that a driver of said vehicle is gazing in a direction other than a neutral direction, based at least in part on having determined that said driver is gazing in said non-neutral direction, selecting a level of obtrusiveness for a warning message, and outputting said warning message at said level.
An apparatus comprising a warning system for a vehicle, said warning system comprising an escalator and a level selector, wherein said level selector receives a constraint signal, a motion signal, and a gaze signal, wherein said constraint signal is indicative on a constraint on motion of a vehicle on a section of a road, wherein said motion signal is indicative of motion of said vehicle, wherein said gaze signal is indicative of whether a driver is gazing in a direction other than a neutral direction, wherein said level selector is configured to select a level of obtrusiveness of a warning signal based at least in part on said gaze signal, and wherein said escalator receives said level from said level selector and outputs a warning signal based on said level.
