2What is an artificial passenger? It’s a software.It's an intelligent presence packed into the dashboard electronics.Sleep preventive device in cars to overcome drowsiness.Life safety system.The software is used for entertainment.
3WHY IT WAS DEVELOPED?Driver fatigue according to the NHTSA annually causes100,000 crashes1,500 fatalities71,000 injurieswhich cause annual cost of $12.5billion.IBM received a patent for a sleepprevention system for use in automobiles
4MAIN USES: Used to prevent accident. Used for entertainment such as it telling jokes and asking question .Establishes interface with other drivers very easily
5Open and close the window of a car automatically and also answer a call for you.If the driver gets a heart attack or he is drunk it will send signals to vehicles nearby about this so driver there become alert.
6What does it do? Detects alarm conditions through sensors. Broadcasts pre-stored voice messages over the speakers.Captures images of the driver.
9Devices that are used in AP The main devices that are used in this artificial passenger are:-Eye tracker.Voice recognizer or speech recognizer.
10How does eye tracking work? Collecting eye movement data requires hardware and software specifically designed to perform this function.Eye-tracking hardware is either mounted on a user's head or mounted remotelyBoth systems measure the corneal reflection of an infrared light emitting diode (LED), which illuminates and generates a reflection off the surface of the eye
11This action causes the pupil to appear as a bright disk in contrast to the surrounding iris and creates a small glitch underneath the pupil.It is this glint that head-mounted and remote systems use for calibration and tracking.If the eyes have been closed for more than approximately 40 of the last approximately 60 frames, the system declares that driver has his eyes closed for too long.
13How does Voice recognizer works?: Heart of the system is a conversation planner.A microphone picks up answer and breaks it down into separate words with speech-recognition software.
14WORKING… A camera built into the dashboard also tracks your lip movements to improve the accuracyof the speech recognition.
15WORKING: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.
16WORKING:If your response is slow or doesn’t make sense, the voice analyzer assumes you are dropping off and acts to get your attention.
19ADVANTAGES 1. Voice control interface 2. Embedded speech recognition 3. Driver drowsiness prevention4. Workload Manager5. Privacy and social aspects
20Other applications 1) Cabins in airplanes. 2) Water craft such as boats.3) Trains and subways.
21conclusionSuccessful implementation of Artificial passenger would allow use of various services in cars (like reading , navigation, downloading music titles , voice games etc.) without compromising a driver safety.
