Introduction
IBM (International business machines corporation, NY) 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.
What is an Artificial Passenger?
Natural language e-companion.
Sleep preventive device in cars to overcome drowsiness.
Life safety system.
Why Such System?
According to a national survey in UK and USA, it is observed that the driver fatigue annually causes,
• 10000 crashes
• 1500 deaths
• 7100 injuries , which causes annual cost of $12.5 billions.
Majority of off-road accidents observed were preceded by eye closure of half and even 2-3 seconds where the normal human eye blinks at 0.2-0.3 seconds.
What Does It Do?
Detects alarm conditions through sensors.
Broadcasts pre-stored voice messages over the speakers.
Captures images of the driver
Working Components
There are some of the components which supports for the working of the system:
Automatic speech recognizer (ASR)
Natural language processor
Driver analyzer
Conversational planner (CP)
Alarm
Microphone
Camera
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.
Natural language processor:-
Processes the decoded signals of textual data provided from the ASR.
Identifies related meanings from the contents of the decoded messages
Driver analyzer:-
Receives the textual data and voice data.
Measures the time response using a clock.
Analysis is both subjective and objective.
Conversational planner:-
It is the heart of the system.
Instructs the language generator to produce the response.
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.
