The 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. 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. This research suggests that we can make predictions about various aspects of driver performance based on what we glean from the movements of a driver’s eyes and that a system can eventually be developed to capture this data and use it to alert people when their driving has become significantly impaired by fatigue. 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. What is an artificial passenger? Natural language e-companion. Sleep preventive device in cars to overcome drowsiness.
