New eyesight tracking techniques improve realistic

craft SimulatorsA simulated flight environment intended for pilot training may quickly be made more realistic with the use of eye-tracking technology developed by experts at the School of Torontos Institute of Biomedical Anatomist (IMBE).

Many safety and cost benefits are received by teaching aircraft pilots under controlled conditions, but to be effective the simulation should be convicingly practical. At present, th e schooling facilities employ large domes and gimballed projectors, or perhaps an array of online video screens, to display computer-generated pictures. But these installation are very pricey and photo resolution is low. Further, it would take an enormous amount of addi to improve photo quality drastically throughout the complete viewed picture.

However , depending on the visual properties with the eye, realism can be obtained by giving a high-resolution area of interest put within a huge, low-resolution discipline of view. If the image-generating computer knows where the pilots fixation is usually, it mage there.

The technology to create this likely was developed by a research crew headed simply by Professor Rich Frecker and Professor Moshe Eizenman. The work was accomplished in cooperation with CAE Electronics Limited. of Montreal with economic support in the Natural Sciences and Anatomist Research Authorities of Canada.

Their eye-tracker can record and examine accurately about 500 attention positions per second. The system works by method of capturing and processing the reflections of a low-level light o f invisible infra-red light shone onto a persons vision.

Multi-element arrays capture the of the eye and digitize the information, which is then processed in real time by a fast, devoted signal digesting unit. The in position between your ligh tre of the pupil reveals the instantaneous direction of eyes.

Developments by IBME staff have drastically increased the speed of signal processing moreover to enhancing accuracy of eye situation estimates. Eizenman believes why these improvements help to make our eye-tracker very effective in monitoring the large G-force environment where the preliminary tends to make larger eye movements because of contraints which can be found on motions of his head.

Within a new era of plane simulators, below development by simply CAE Gadgets Ltd. of Montreal, a head tracker which tells the direction of the pilots head is mounted on top of the helmet. The attention tracker can be mounted on the front of the helmet, and is ll wherever the pilots eye is fixating.

Frecker said that good integration of your eye tracker into the novel helmet-mounted CAE flight simulator would result in a new generation of simulators that would most likely replace the existing large domes and difficult video screen units.

Primary tests with the integrated system will be performed in effort with CAE Electronics for Williams Bomber command Base in Arizona later this year.
