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.

EXISTING SYSTEM
Use of stimulation drinks like tea or
coffee.
Take some tablets to prevent
sleeping.

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 widely used to
prevent accident.
• Artificial passenger device is also
used for entertainment such as
telling jokes and asking questions.

• If the driver gets a heart attack or
he is drunk, it will send signals to
vehicles nearby about this so that
the driver there becomes alert.
• Therefore this is a natural
language companion and acts as a
life safety system.

About artificial passenger
 Resident in the software and chips
embedded in the automobile dashboard.
 The heart of the system is a conversation
planner that holds the profile of one or more
drivers including details of his interests and
profession.

 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.

 If the driver replies 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.

Touch sensitive wheel
The driver can answer a call using the
touch sensitive wheel. It is the touch
sensitive wheel.

Speech recognition device

Camera
A camera is used to keep track of lips
movement.

Components used…
 Automatic speech
recognition.(ASR)
 Natural language processor.(NLP)
 Driver analyzer.
 Conversational planner
 Alarm .
 External service provider.

o Automatic speech recognition (ASR)
 Decodes the driver’s voice using natural
language processor.
o Natural language processor (NLP)
 Processes the decoded signal.
 Produces variants of responses
according to the driver’s input.
o Driver analyzer
 Receives the voice data and measures
the time of response.

o Conversational planner (CP)
 Instruct the natural language processor
to produce the response.
o Alarm
 If the planner receives information
that driver is asleep, it activates the
alarm system.
o External service provider
 This 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 the frequencies of the head movements
of the driver within a selected time period.
 Determine frequency of eye blinking and eye
closing.

 Determine frequency of
yawning of the driver within
selected time period.
 Generating an alarm signal if
the above frequencies exceed a
selected threshold value.

APPLICATIONS
 Prevent driver from falling
asleep during long trips.
 Open and close the windows of
the car automatically.
 It 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.

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