The Artificial Passenger (AP) is an artificial intelligence based companion that will be resident in software and chips embedded in the automobile dashboard. The heart of the system is a conversation planner that holds a profile of you, including details of your interests and profession. When activated, the AP uses the profile to cook up provocative questions such as “Who was the first person you dated?” via a speech generator and in-car speakers.

Studies of road safety found that human error was the sole cause in more than half of all accidents. One of the reasons why humans commit so many errors lies in the inherent limitation of human information processing. With the increase in popularity of Telematics services in cars (like navigation, cellular telephone, internet access) there is more information that drivers need to process and more devices that drivers need to control that might contribute to additional driving errors. This seminar is devoted to a discussion of these and other aspects of driver safety.

The natural dialog car system analyzes a driver’s answer and the contents of the answer together with his voice patterns to determine if he is alert while driving. The system warns the driver or changes the topic of conversation if the system determines that the driver is about to fall asleep. The system may also detect whether a driver is affected by alcohol or drugs.

A microphone picks up your answer and breaks it down into separate words with speech-recognition software. A camera built into the dashboard also tracks your lip movements to improve the accuracy of the speech recognition. A voice analyzer then looks for signs of tiredness by checking to see if the answer matches your profile. Slow responses and a lack of intonation are signs of fatigue. If you reply quickly and clearly, the system judges you to be alert and tells the conversation planner to continue the line of questioning. If your response is slow or doesn’t make sense, the voice analyzer assumes you are dropping off and acts to get your attention.

The system, according to its inventors, does not go through a suite of rote questions demanding rote answers. Rather, it knows your tastes and will even, if you wish, make certain you never miss Paul Harvey again. This is from the patent application: “An even further object of the present invention is to provide a natural dialog car system that understands content of tapes, books, and radio programs and extracts and reproduces appropriate phrases from those materials while it is talking with a driver. For example, a system can find out if someone is singing on a channel of a radio station. The system will state, “And now you will hear a wonderful song!” or detect that there is news and state, “Do you know what happened now hear the following and play some news”. The system also includes a recognition system to detect who is speaking over the radio and alert the driver if the person speaking is one the driver wishes to hear.” Just because you can express the rules of grammar in software doesn’t mean a driver is going to use them.

The AP is ready for that possibility: It provides for a natural dialog car system directed to human factor engineering for example, people using different strategies to talk (for instance, short vs. elaborate responses). In this manner, the individual is guided to talk in a certain way so as to make the system work e.g., “Sorry, I didn’t get it. Could you say it briefly?” Here, the system defines a narrow topic of the user reply (answer or question) via an association of classes of relevant words via decision trees. The system builds a reply sentence asking “what are most probable word sequences that could follow the user reply.”
