Press Release Summary: Bedford, Massachusetts, USA - Applied Science Laboratories
(ASL) has again answered the call by finding new ways to incorporate an eye tracking
system, namely the Eye-Trac 6 LRO with fMRI systems and has captured the attention
of many researchers who are endeavoring to increase their understanding and improve
the treatment of brain injuries and illnesses.

Press Release Body: ASL plans to continue to forge new partnerships and maintain its
leadership in developing and building systems that track, record and analyze human
eye movements and pupil dynamics for eye-tracking applications that include
medicine, cognitive psychology, training, simulation, biomechanics, human factors
research, web design, usability and many more.

In making the announcement, Virginia Salem, Vice President of Sales, of ASL said,
"The true challenge faced by our professional team is to make the theoretical come
to life by brainstorming the problem across our entire organization and designing a
practical, user-friendly eye tracking solution".

The integration of the Eye-Trac 6 LRO with fMRI equipment was not without several
obstacles as it gained widespread acceptance as a viable enhancement. The potential
for interference in the fMRI data or images by the Eyetracker as well as how best to
physically mount the two systems together were the first of many tests that team ASL
faced. The utilization of magnets ranging from 1.5T to 4T to allow the optics to
track distances of up to 16 feet coupled with placing the optics outside the magnet
room minimized the interference risk. While Team ASL are not MR experts, the
approach of working in partnership with their clients was the key to meeting the
specific technical challenges that the Eye-Trac 6 LRO was required to overcome which
included, but were not limited to:
· Working in conjunction with any stimulus display
· Measuring real time pupil size
· Record data and analyze it offline
· Adjustable between 50/60Hz, 120Hz and 240Hz
· Measuring Saccades
· Distinct and easy to identify pupil illumination (bright pupil technique) for all
subjects including those wearing glasses or contact lenses

Applied Science Laboratories has been a pioneer in the examination of human eye
movements and pupil dynamics for over 30 years. ASL was the first company to develop
a head-mounted eye tracker, eye/head integration, parallax-free optics, and many
other features that have become industry standard. For more information, visit
