Method and system for providing directions for driving
First Claim
1. An apparatus for providing information to the driver of a vehicle, the apparatus comprising:
- a touch screen display that iteratively displaysa first display that presents a menu of driver-selectable destination categories, each of the driver-selectable destination categories corresponding to a predefined geographic region, anda second display that in response to a selection by the driver of at least one of the driver-selectable destination categories presents a list of destinations corresponding to the at least one of the driver-selectable destination categories selected;
a positioning and motion determining device which determines a location of the vehicle and whether the vehicle is moving or at rest;
a storage device including stored information, wherein the stored information comprises information about a location of a desired driver action, the location of the desired driver action being based upon a destination selected by the driver from the list of destinations, and wherein the stored information further comprises at least one among location-related information, e-mail, advertising, weather information, and traffic information; and
a comparator which compares the location of the vehicle with the stored information about the location of the desired driver action and which provides a signal when the location of the vehicle is in a predetermined relationship to the location of the desired driver action, wherein the predetermined relationship is determined based upon an estimated time when the driver should take the desired driver action; and
a projector which displays a message on the windshield indicating the desired driver action in response to the signal;
wherein when the positioning and motioning determining device determines that the vehicle is at rest the projector displays images corresponding to at least one among the location-related information, e-mail, advertising, weather information, and traffic information.

Abstract
A system and method of providing information (such as directions) to a driver of a vehicle while driving the vehicle without requiring that the driver remove his eyes from looking out the windshield at the road ahead. A positioning device is associated with the vehicle and determines the present location of the vehicle which is compared to a desired location (e.g., the location of a desired turn at an intersection) necessary to reach a preset destination which has been stored. When the vehicle is in a predetermined location (e.g., 500 feet or 10 second before the intersection), an advisory message to the driver is projected onto the windshield using a heads-up display projector so that the driver can prepare for and make the necessary movement (e.g., turning the correct way at the desired intersection). An optional auditory signal can provide a message indicating the necessary action, either in general or specifically (through a speech synthesizer), with optionally different sound indicators, depending on the urgency of the action. A wireless receiver used with the present invention can display other information such as road conditions, traffic and weather information, as well as advertising and e-mail. The present invention contemplates that images of intersections (live pictures, photos or sketches) may be displayed to indicate the proper turn and provide landmark information to assist in determining the appropriate turn.

19. A method for providing information to the driver of a vehicle comprising:
-
performing, via a processor, the steps of; receiving at least one desired destination associated with the driver; determining a route for the driver to reach the desired destination including at least one turn for the vehicle to reach the desired destination; determining a location of the vehicle and when the vehicle is approaching the at least one turn, and providing a message to the vehicle, wherein the determining of when the vehicle is approaching the at least one turn is determined based upon the location of the vehicle and a comparison of the location of the vehicle with stored information about a location of the at least one turn, wherein the location of the at least one turn is determined based upon an estimated time when the driver should make the at least one turn; displaying the message on a windshield of the vehicle when the vehicle is approaching the at least one turn so that the driver may be informed of the at least one turn at an appropriate time without requiring the driver to remove his eyes from the windshield; and determining when the vehicle is at rest and, when the vehicle is determined to be at rest, providing at least one among location-related information, e-mail, advertising, weather information, and traffic information, which is presented as at least one of a visual image displayed on the windshield of the vehicle and an audible signal produced within the vehicle.
