THE
EYEGAZE COMMUNICATION SYSTEM
The
Eyegaze Communication System is an FDA- approved communication
and control system for people with complex physical disabilities.
The system is operated entirely with the eyes. By looking
at control keys displayed on a screen, a person can synthesize
speech, control his environment (lights, call bells, etc.),
type, run computer software, operate a computer mouse, and
access the Internet and e-mail. Eyegaze Systems are being
used to write books, attend school and enhance the quality
of life of people with disabilities all over the world.
[Note: Detailed
Medical and Technical Information is available with
complete discussions of eye control, eye conditions and
diseases, positioning, possible medication side effects,
mental abilities that may have an effect, and the likelihood
that Eyegaze can be used depending on the person's medical
diagnosis.]

Who's using the Eyegaze System?
Eyegaze System users include adults and
children with cerebral palsy, spinal cord injury, brain
injury, ALS, multiple sclerosis, brainstem stroke (Locked-In
syndrome), muscular dystrophy, and Werdnig-Hoffman syndrome.
Eyegaze Systems are being used in homes, offices, schools,
hospitals, and long-term care facilities.
Please see the
Photo Gallery of Eyegaze Users for pictures and brief
biographies of several Eyegaze System users and Books
written with the Eyegaze System.
How does the Eyegaze System work?
As a user sits in front of the Eyegaze monitor,
a specialized video camera mounted below the monitor observes
one of the user's eyes. Sophisticated image processing software
in the Eyegaze System's computer continually analyzes the
video image of the eye and determines where the user is
looking on the screen. Nothing is attached to the user's
head or body. Click here to see footage of Eyegaze in use.
How does the user run the Eyegaze System?
A user operates the Eyegaze Communication System
by looking at rectangular keys that are displayed on the control
screen. To "press" an Eyegaze key, the user looks at the key
for a specified period of time. The gaze duration required
to visually activate a key, typically a fraction of a second,
is adjustable. An array of menu keys and exit keys allow the
user to navigate the Eyegaze programs independently.
What can the user do with the Eyegaze System?
The Main Menu appears on the screen as soon
as the user completes a 15-second calibration procedure.
The Main Menu presents a list of available Eyegaze programs.
The user calls up a desired program by looking at the Eyegaze
key next to his program choice.
The
Phrases program, (note: click on red
links to see program screens) along with the speech synthesizer,
provides quick communications for non-verbal users. Looking
at a key causes a preprogrammed message to be spoken. The
Phrases program stores up to 126 messages, which can be
composed and easily changed to suit the user.
Simple word processing can be done using
the
Keyboard program. The user types by
looking at keys on visual keyboards. Four keyboard configurations,
simple to complex, are available. Typed text appears on
the screen above the keyboard display. The user may "speak"
or print what he has typed. He may also store typed text
in a file to be retrieved at a later time. The retrieved
text may be verbalized, edited or printed.
The Computer Access Program permits the
Eyegaze Communication System to act as a peripheral keyboard
and mouse interface to a Windows computer. The user can
run any off-the-shelf software he chooses on the second
computer. He can access the Internet and send e-mail by
looking at keyboard and mouse control screens on the Eyegaze
monitor. The programs being run are displayed on the second
computer's monitor. Typed text appears simultaneously on
the Eyegaze monitor and the second PC's screens.
For children or pre-reading adults, Speaking
Dynamically Pro offers a wide range of
icon-based communication possibilities, and may be fully
accessed by eye control.
The Lights
and Appliances program, which includes
computer-controlled switching equipment, provides Eyegaze
control of lights and appliances anywhere in the home or
office. No special house wiring is necessary. The user turns
appliances on and off by looking at a bank of switches displayed
on the screen.
Visually controlled Games include two Paddle
games, and
Score
Four.
The Read
Text program allows the user to select
text for display and to "turn pages" with his eyes. Any
ASCII format text can be loaded for the user to access.
Electronic texts of books are available from Services for
the Blind as well as many other places on the Internet.
What skills does the user need?
- 1. Good control of one eye
- 2. Ability to keep eye in the Eyegaze
camera's range
- 3. Some reading or word recognition skill
How do you calibrate?
A 15
second calibration procedure is required
to set up the System for a particular user. To calibrate,
the user fixes his gaze on a sequence of small circles that
the system displays on the Eyegaze screen. There is no need
to recalibrate if the user moves away from the Eyegaze System
and returns later.
Can the Eyegaze System be customized?
Yes. The Eyegaze programs have many adjustable
parameters. The gaze duration, phrases and appliance labels,
for example, can all be easily changed. An assistant or caregiver
may edit the Eyegaze text or change Eyegaze data values by
running a configuration program called ECS Settings.
Is the Eyegaze System Portable?
Yes. The system consists of a small computer,
a flat panel monitor, a small camera, and an adjustable
table mount. The computer weighs only 6 lbs (2.7 kg) and
its dimensions are 8 x 7 x 3 inches (20 x 18 x 8 cm).
What environment does the Eyegaze System need?
Because eyetracking uses infrared light to
illuminate the eye, other sources of infrared light must be
kept to a minimum. Fluorescent rather than incandescent lighting
insures the best system accuracy. The Eyegaze System should
be located away from strong sunlight.
Is the Internet accessible using the Eyegaze System?
Yes. The user can independently go on-line,
through two methods - by using the Computer Access option
and connecting the second PC to the internet, or by using
the EyeMouse Option.
Where can we see an Eyegaze System?
Call us or one of our
distributors or assessment centers to come try the system
or to have a system brought to you.
