IntroductionWhat is an artificial passenger?

“ The AP is an artificial intelligence–based companion that will be resident in software and chips embedded in the automobile dashboard ”.

What does it do?Detects alarm conditions through sensors.Broadcasts pre-stored voice messages over the speakers.Captures images of the driver

Background of the invention

IBM (International Business Machines Corporation, Newyork ) has developed a software that holds the conversation with driver to determine whether the driver can respond alertly enough, called “Artificial Passenger”.The name was firstly suggested in an article in new scientist magazine.This was designed to make solo journey safer and more bearable.

Why Such System?According to a national survey in UK and USA, it is observed that the driver fatigue annually causes,

I. 100000 crashesII. 15000 deaths III. 71000 injuries which causes annual cost of $12.5

billions.Majority of off-road accidents observed were preceded by eye closure of half and even2-3 seconds where the normal human eye blinks at 0.2-0.3 seconds.

The main devices that are used

in this artificial passenger are:-

Eye tracker or Camera.

Voice recognizer or speech

recognizer.

Touch sensors.

Working ComponentsThere are some of the components which supports

for the working of the system:Automatic Speech Recognizer (ASR)Natural Language Processor (NLP)Driver analyzerConversational planner (CP)AlarmMicrophoneCamera

Working Components( contd.)Automatic speech recognition :-

There are two ASRs used in the system:First one is “speaker independent” and used for decoding voice signals of the driver.Second one operates with voice car media and decodes tapes, audio book, telephone mails etc.

Working Components (contd.) Natural language processor : -

Processes the decoded signals of textual data provided

from the ASR.

Identifies related meanings from the contents of the

decoded messages.

Produces variant of responses.

This output goes to the driver analyzer as an input.

Working Components (contd.) Driver analyzer :-

Receives the textual data and voice data. Measures the time response using a clock.Analysis is both subjective and objective.Time responses, conclusions about driver’s alertness will output to the conversational planner.

Working Components (contd.) Conversational planner:-

It is the heart of the system.

Instructs the language generator to produce the

response.

If the driver is in perfect condition CP instructs the

language generator to continue the conversation

otherwise it is instructed to change the conversation.

Working Components (contd.) Alarm:- If the CP (conversational planner) receives

information that the driver is about to fall asleep an alarm system is activated.

Microphone:- For picking up the words and separate them by

some internally used software for conversation.

Working Components (contd.)

Camera:-

This will track the lip movements of the driver.

Used for the improvement for the accuracy of the

speech recognition.

Advantages and Disadvantages Advantages:-

Artificial Passenger is broadly used to prevent accident.

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

Disadvantages:-

It is costly. It can only be installed to high profiled cars.

Application

Prevents the driver, falling asleep during long and solo trip. In any problem it alerts the vehicles near by this, so the driver there become alert.Opens and closes the doors and windows of the car automatically.It is also used for the entertainment. This system can also be used in other situations such as

I. Security guardII. Operators at nuclear plantsIII. Pilots of airplane

Future Application

Will provide us with a shortest-

time routing based on road conditions

changing because of weather and traffic,

information of about the cars on the route,

destination requirement (as flight has been

delayed).

Conclusion

Successful implementation of artificial

passenger would allow use of various services in

car like reading e-mails, navigation, downloading

music files, voice games without compromising a

driver safety.
