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 0.3second.


3/26

EXISTING SYSTEM..

y Use of stimulation drinks like tea or coffee.

y Take some tablets to prevent sleeping.


4/26

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



5/26


y A sleep prevention dialogue based car system.

y Design to make long solo journey more enjoyable and safer.

y Prevent drivers drowsiness via the speech interactivity.


6/26

What does it do?

y Engage in conversation with driver related to his interest.

y Also amuse the driver with the interactive games or jokes.

y More stimulating content for driver who appears to be

fatigued.


7/26

Components used

y Automatic speech recognition.(ASR)

y Natural language processor.(NLP)

y Driver analyzer.

y Conversational planner

y Alarm.

y External service provider.


8/26

AUTOMATIC SPEECH RECOGNITION

(ASR)

y To convert the acoustic signal captured by microphone to the set

of words .

y Output of the ASR act as an input to further Natural language

processor.


9/26

FEATURES OF ASR

y Should be working in real time circumstances.

y Large vocabulary.

y Speaker independent.


10/26

NATURALLANGUAGE PROCESSOR

(NLP)

y Form of human to computer interaction.

y Required as computer cannot understand human language.

y Produce variant of responses according to driver response.


11/26

DRIVER ANALYZER

y Measure the time response using the in build clock.

y Time response give us conclusion about the drivers alertness.

y These responses will pass on to the conversation planner.


12/26

CONVERSATIONAL PLANER

y It is heart of the system.

y Hold the profile of the driver that include his hobbies and

profession.

y Instructs the language generator to produce the response.


13/26

ITS FUNCTION

y If the driver is in perfect condition CP instructs the language

generator to continue the conversation.

y otherwise , it will change the conversation or sound an alarm ,open up the window.


14/26

ALARM

y If conversational planner receive that driver is about tofall asleep an alarm system is activated.

MICROPHONE

y For picking up words and separate

them by some internally used softwarefor conversation.


15/26

CAMERA

y A camera is built on the dashboard or middle of steering so as

to track your lip movement to improve the accuracy of the

speech recognition.


16/26

EXTERNAL SERVICE PROVIDER

y For facilitating the communication in between the dialog system

and remotely located external service provider.

y External service provider is coupled through the adapter to thecar media ,driver analyzer module and conversational planner.

WORKING

y A microphone picks up your answer and breaks it down into

separate words with speech-recognition software.

y

A camera built into the dashboard also tracks your lipmovements to improve the accuracy of speech recognition.


20/26

WORKING..

A voice analyzer then looks for signs of tiredness by checking

to see if the answer matches your profile. Slow responses and

lack of attention 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.


21/26

WORKING.

y If your response is slow or doesnt make sense, the voiceanalyzer assumes you are dropping off and acts to get yourattention.

y If driver displays signs of fatigue, the artificial passengermight be programmed to open all the windows, sound a

buzzer, increase background music volume, or even spray thedriver with ice water.


22/26

APPLICATION

Interface with Neighboring Cars -Determines if a driverpresents a high safety risk for ex. falling asleep, tired,inexperienced or under the influence of alcohol and signalsthe cars nearby to be careful of the driver.

Medical Application -The system can monitor a driver anddetect if they are sick ,for ex. having a stroke or heartattack.

It is also used for the entertainment.

Also used in cabins in airplanes, trains, boats etc


23/26

FUTUREENHANCEMENTS

y Will provide us with shortest time routing based on road

conditions changing because of weather and traffic,

information about the cars on the route, destination

requirement.


24/26

CONCLUSION

y Method for monitoring driver alertness

y Sufficient time to avert an accident.
