ARTIFICIAL PASSENGER PRESENTED BY ARJUN.K.R S7 CS ROLL NO:08 DATE OF PRESENTATION :-19-08-2009
Page 1
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. Page 2
EXISTING SYSTEM.. • Use of stimulation drinks like tea or coffee. • Take some tablets to prevent sleeping.
Page 3
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” Page 4
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 .
Page 5
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. Page 6
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. Page 7
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. Page 8
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 Page 9
Mobile Indicator Device… The driver can answer a call using the touch sensitive wheel.

Components used… • • • • • •
Automatic speech recognition.(ASR) Natural language processor.(NLP) Driver analyzer. Conversational planner Alarm . External service provider.
Page 14
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 15
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 18
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
Page 19
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.
Page 20
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.
Page 21
CONCLUSION • Artificial passenger is an effective mechanism to prevent driver fatigue.
• Successful implementation of artificial passenger would decrease road accidents to a great extent.
