aircraft simulators essay
A simulated airline flight environment pertaining to pilot schooling may rapidly
be made more realistic through theuseofeye-tracking
technology developed by analysts at theUniversityof
Torontos Commence of Biomedical Engineering (IMBE).
A large number of safety and cost rewards are obtained by teaching
aircraft aviators under controlled conditions, but for be effective
the simulation must be convicingly reasonable. At present, th e
training facilities use large domes and gimballed projectors, or perhaps
an array of online video screens, to display computer-generated images.
But these installations are incredibly expensive and image resolution
is low. Further, it will take a significant amount of addi to
improve picture quality drastically throughout the entire viewed
landscape.
Nevertheless , based on the visual real estate of the eye
realism can be obtained by providing a high-resolution area of
interest insert within a significant, low-resolution discipline of look at.
In case the image-generating laptop knows where pilots
hinsicht is, it mage there.
The technology to make this possible was developed by a
research crew headed simply by Professor Richard Frecker and Professor
Moshe Eizenman. The job was carried out in collaboration with
CAE Electronics Limited. of Montreal with economical support through the
Natural Savoir and Executive Research Authorities of Canada.
All their eye-tracker can easily record and analyze effectively up to
500 eye positions per second. The system works by means of
recording and finalizing the glare of a low-level beam o f
undetectable infra-red mild shone onto the eye.
Multi-element arrays capture the of the eye and
digitize the information, which can be then highly processed in real time
by a fast, devoted signal digesting unit. The in
position between the ligh tre of the pupilrevealsthe
instantaneous direction of gaze.
Developments by the IBME staff have drastically increased
the velocity of sign processing additionally to enhancing accuracy
of eye placement estimates. Eizenman believes thatthese
improvements produce our eye-tracker very effective in monitoring
the top G-force environment where the preliminary tends to make
much larger eye motions because of contraints which exist on
actions of his head.
Within a new era of aeroplanes simulators, beneath
development by CAE Gadgets Ltd. of Montreal, a head tracker
which tells the path of the pilots head is usually mounted on top rated
of the helmet. The eye tracker is attached to the front of the
head protection, and is lmost all exactly where the pilots eye is fixating.
Frecker said that effective integration of our eye
tracker into the new helmet-mounted CAE flight sim would
cause a new technology of simulators that would probably
replace the present large domes and difficult video screen
units.
Preliminary tests of the integrated system will be carried out
in collaboration with CAE Electronics for Williams Air Force Base
in Arizona after this year.
