The Eye Tracking
Assessment, Monitoring, and
Visionary Sciences Methodology
An evidenced based approach to assess
monitor , and remediate various
pathological conditions while reducing
the subjective bias in several
Our goal is to apply cutting edge
technology to create the most accurate
system for evidence based medicine.

Eye tracking in action
You’ve just seen the calibration sequence
and scan paths used in the eye tracking
The machine is able to capture eye
movements at any one time and over time in
order to accurately determine where the eye
focuses (fixation point), as well as the
duration of each fixation.
The eye tracking system records all
information for analysis and comparison to
normal groups through our proprietary data
analysis software and database.
Scanpaths, density patterns, and attentional
A single stimulus image is used.
The actual fixation points are represented by
bubbles the diameter of which reflects both the
area of fixation and duration of fixation.
Additional data is recorded as a “density
pattern” which reflects the number of fixations
in a given location or the most frequently
Finally, the 3-D graphical representation of the
scan path is demonstrated as both a “hot
spot”, as well as an attentional landscape.
Visionary Sciences seeks to demonstrate
the utility of eye tracking technology with
ADHD, Autism, Autistic Spectrum
Disabilities, Traumatic Brain Injury [(TBI)
with special reference to both PTSD and
sport related injuries], and early stage
dementia, as well as changes in
sensorium or cognitive status and the
risk of falling in the elderly.
A collaboration with Advocate-Condell Medical
Visionary Sciences seeks to collaborate with
Advocate-Condell in applying our proprietary
algorithms and applications to develop statistically
accurate databases to reduce the subjective aspects
of current diagnostic and treatment methods in the
Pediatrics, Gerontology, Neurology, Rehabilitation, a
nd Outpatient Services to assess, monitor, and
remediate patients using eyetracking data to support
clinical decision-making and follow-up care.
VS proposes a model of care beginning at
intake, progressing through hospital care, and post-
discharge follow-up care and monitoring.
Our proprietary algorithms and
databases can help define whether an
individual falls within one of several
groups of pathology.
This kind of evidenced based
technology reduces the subjective
nature of evaluation and treatment.
VS Eyetracking versus the current medical
Eye tracking technology in addition to
producing more valid and reliable data is
○ Customizable (modular)
○ Repeatable (no “halo”/learning effects)
f-MRI, CAT scans, PET
scans, Neuropsychological Testing, etc.
Cumbersome (not portable)
Time consuming (multiple sessions)
Culturally biased in neuropsychological testing
One-size fits all (not customizable)
Not repeatable in most cases (imaging costs
and approvals) and by learning factors
Visionary Sciences Model for Application
Compare an individual with their own
performance over time (T1, T2)
Compare an individual with groups
(matched for age, sex, race, SES, etc)
Can track and determine optimal doses
of chemotherapeutic agents over time.
This provides accurate titration and
effectiveness measures. Currently, this
data is unavailable to physicians and
VS Model for Application
Can assess the effectiveness of other
testing, ANAM, imaging)
Can be used as a training device for
medical and ancillary staff, the
development of expert systems.
Can be used to remediate, train, and
patients, families, educators, and staff.
The Visionary Sciences Team
Richard A. Markin, PhD is the CEO of the company and is a clinical psychologist with
over 30 years of clinical experience. Dr. Markin applies complex adaptive systems and
network theory to study the timing and synchronization of the brain, the role of affect
and narrative in normal and pathological development, and various self issues. Dr.
Markin develops software applications for research and service with both clinical
populations and those in high stress situations that must optimize performance, and
designs specialized environments and training for the mental health, education and
business fields .
Leonard T. Carr, MD is a psychiatrist who specializes in both children and adults. Dr.
Carr was a civil engineer and software developer before becoming a physician. He
founded the North Shore Wellness Center, Ltd., which provides for the evaluation and
treatment of a variety of patient populations and has special expertise in children and
adolescents with co-morbid disorders and with adults and geriatrics with a number of
co-existing biochemical problems.
Anthony D. Vertino, PsyD is a clinical psychologist with a broad background in
neurobehavioral psychology. He has done extensive testing and treatment with
children, adolescents and adults and has specialized in geropsychology, both in terms
of behavioral interventions and administration. He has extensive knowledge of
computer assisted learning, database management, statistics and research design.
Jason Leigh, PhD is the director of the Electronic Visualization Laboratory and
Associate Professor of Computer Science at the University of Illinois at Chicago
specializing in advanced visualization technologies and techniques. Through the
EVL, Jason has developed and integrated eye-tracking technologies, virtual reality
environments, and statistical measurements.
