NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIRCRAFT SIMULATORS
|
|
|
|
A simulated flight environment for pilot training may soon be made more
|
|
realistic through the use of eye-tracking technology developed by
|
|
researchers at the University of Toronto's Institute of Biomedical
|
|
Engineering (IMBE).
|
|
|
|
Many safety and cost benefits are obtained by training aircraft pilots
|
|
under simulated conditions, but to be effective the simulation must be
|
|
convicingly realistic. At present, th e training facilities use large domes
|
|
and gimballed projectors, or an array of video screens, to display
|
|
computer-generated images. But these installations are very expensive and
|
|
image resolution is low. Further, it would take an enormous amount of addi
|
|
to improve image quality significantly throughout the whole viewed scene.
|
|
|
|
However, based on the visual properties of the eye, realism can be
|
|
obtained by providing a high-resolution 'area of interest' insert within a
|
|
large, low-resolution field of view. If the image-generating computer
|
|
'knows' where the pilot's fixation is, it mage there.
|
|
|
|
The technology to make this possible was developed by a research team
|
|
headed by Professor Richard Frecker and Professor Moshe Eizenman. The work
|
|
was carried out in collaboration with CAE Electronics Ltd. of Montreal with
|
|
financial support from the Natural Sciences and Engineering Research
|
|
Council of Canada.
|
|
|
|
Their eye-tracker can record and analyze accurately up to 500 eye
|
|
positions per second. The system works by means of capturing and processing
|
|
the reflections of a low-level beam o f invisible infra-red light shone
|
|
onto the eye.
|
|
|
|
Multi-element arrays capture the image of the eye and digitize the
|
|
information, which is then processed in real time by a fast, dedicated
|
|
signal processing unit. The difference in position between the ligh tre of
|
|
the pupil reveals the instantaneous direction of gaze.
|
|
|
|
Developments by the IBME team have significantly increased the speed of
|
|
signal processing in addition to enhancing accuracy of eye position
|
|
estimates. Eizenman believes that "these improvements make our eye-tracker
|
|
very effective in monitoring the large G-force environment where the pilot
|
|
tends to make larger eye movements because of contraints which exist on
|
|
movements of his head".
|
|
|
|
In a new generation of aircraft simulators, under development by CAE
|
|
Electronics Ltd. of Montreal, a head tracker which tells the direction of
|
|
the pilot's head is mounted on top of the helmet. The eye tracker is
|
|
mounted on the front of the helmet, and is ll exactly where the pilot's eye
|
|
is fixating.
|
|
|
|
Frecker said that "successful integration of our eye tracker into the
|
|
novel helmet-mounted CAE flight simulator would result in a new generation
|
|
of simulators that would likely replace the current large domes and
|
|
cumbersome video display units."
|
|
|
|
Initial tests of the integrated system will be carried out in
|
|
collaboration with CAE Electronics at Williams Air Force Base in Arizona
|
|
later this year.
