• The design was done collaboratively within the
Winter 2010-11 Mini-Project course taught by
Prof. Dov Dori
• In response to the call for contest at
INCOSE_IL 2011
• System creatively reduces accidents due to
drivers’ fatigue by focusing on treating the driver
after fatigue has been detected to achieve
decrease in accident likelihood
More than 20% of
highway traffic accidents
are caused as a result of
driver fatigue.
The average driver is
not always alert to his
state of fatigue
Prevention of driving
under “fatigue
influence” using law
enforcement is
impossible
Reduce the probability of accidents caused
by driver fatigue
•GOALS:
• Inform the driver of his/her awareness status
•
•
Slow down the process of falling asleep
Recommend to the driver to take an alternative way
to the nearest possible resting point

Every driver/car owner who understands the danger
of driving under fatigue condition
•
Companies who want to keep track of their workers
so they do not drive under fatigue condition
•
•
Parents, who want to take care of their children
•
The Army, police
•Vehicle
producers for use in new cars
Available systems today
•
Disadvantages:
No treatment! Just detection
High cost
Driver-dependable
Not customizable
Invasive or annoying
Not reliable
Alerts long after the driver should not be
on the road
The system principle
•
EEG – impossible in driving environment
•
Physical symptoms - unreliable
•
Eyes and face symptoms – the best way for fatigue
detection for our needs
Detection using existing technologies in order to
detect and manage driver fatigue.
•FIVE different parameters:
• Eyelid closure (PERCLOS)
• Blink frequency
• Head movement
• Fixed gaze direction
• Facial expression
Produce two signals:
Fatigue - dangerously tired – must find a way to stop
urgently
•
Drowsiness - moderately tired – can continue with
stimulations as long as not fatigue
•
SleepBuster responds differently based on driver state.
In the instance of fatigue, which we consider to be more
dangerous, we will use more extreme remedies:
•
Automatically calling a person of driver’s choice
•
Programming the GPS to find the closest rest area.
While in a drowsy state, we will try and occupy the driver in
order to keep him alert. We will request that he do several tasks
of his customize:
Raising and changing the radio volume
• Requiring the driver to grasp the wheel tight and sit up straight
• Opening and closing different windows sporadically at different
opening widths
• Tuning air-condition to be cooler
• Playing trivia and monitoring driver response
•
This should delay the driver entering the fatigue state for as long
as possible.
