INTRODUCTION
• According to national survey in UK and USA it is observed that the driver fatigue annually causes
1000 crashes. 1500 deaths. 7100 injuries.• Majority of road accidents observed were caused
by eye-closure of one-half second to as long as 2 to 3 seconds.
• It is said that the normal human eye blinks lasts 0.2 to 0.3 second.

EXISTING SYSTEM..
• Use of stimulation drinks like tea or coffee.
• Take some tablets to prevent sleeping.
Page 4
In order to avoid the disadvantages of the existing system IBM developed a software
to determine whether the driver can respond alertly enough .
The device is named as
“ARTIFICIAL PASSENGER”

What is artificial passenger?
• Artificial Passenger is broadly used to prevent accident.
• Artificial Passenger device is also used for
entertainment such as it telling jokes and
asking question .

What is artificial passenger?
• Artificial Passenger component establishes interface with other drivers very easily .
• 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.
• Therefore AP is a Natural language companion and acts as a Life safety system.

About Artificial Passenger…..
• Artificial intelligence based companion
• Resident in the software and chips embedded in the automobile dashboard.
• The heart of the system is a conversation planner that holds a profile of one or more drivers including details of his interests and profession.

About Artificial Passenger…..
• A microphone picks up the driver’s answer and breaks it down to separate words with speech recognition software.
• An in-built camera placed on the dash board keeps track of the driver’s facial state.
• A voice analyzer looks for signs of tiredness.

About Artificial Passenger…..
• If the driver reply clearly and quickly then he is
alert.
• If the response is slow the device assumes that he is sleepy.
• If he is not active the AP will try to get the attention of the driver by even sprinkling water onto the driver’s face

Components used…
• Automatic speech recognition.(ASR)
• Natural language processor.(NLP)
• Driver analyzer.
• Conversational planner
• Alarm .
• External service provider.
Page 15
Components• Automatic Speech Recognition(ASR) Decodes the driver voice using NLP
• Natural Language Processor Process the decoded signal. Produces variants of responses
according to the driver’s input
• Driver Analyzer Receives the voice data and it measure
the time of response
Page 16
Components
• Conversational Planner(CP) Instruct the natural language processor to
produce the response• Alarm If the CP receives information that driver is
asleep it activates the alarm system.• External Service Provider The AP also has a wireless internet which is
used to constantly update the NLP library

Working• Aiming a single camera at the head of the
driver.
• Detecting frequencies of the head movements of the driver within a selected time period.
• Determine frequency of eye blinking and eye closing.
Page 19
Working
• Determine frequency of yawing if the driver within selected time period.
• Generating an alarm signal if the above frequencies exceeds a selected threshold
value

APPLICATIONS…
• Prevent driver from falling asleep during long trips.
• Open and close the window of a car automatically.
• It will answer a call for the driver.• Artificial Passenger is also used for
entertainment.

FUTURE APPLICATIONS
• In the future, based on road, weather and traffic conditions, AP will provide the driver with shortest time routing.
• This is done with the help of GPS and speech generator.

CONCLUSION
• Artificial passenger is an effective mechanism to prevent driver fatigue.
• Successful implementation of artificial passenger would decrease road accidents to a great extent.
