THE MAIN MENUTHE MAIN MENUThe Main Menu appears on the screen as soon
as the user completes a 15-second calibration procedure.
THE PHRASE PROGRAMTHE PHRASE PROGRAM
The Phrase program, along with
the speech synthesizer, provides
quick communications for non-
verbal users.
The Phrases program stores up
to 126 messages, which can be
composed and easily changed to
suit the user.
THE TELEPHONE PROGRAMTHE TELEPHONE PROGRAM Non-verbal users may access the speech synthesizer
to talk on the phone
RUN SECOND PC RUN SECOND PC As a keyboard

OPERATIONAL ENVIRONMENT OPERATIONAL ENVIRONMENT
The Eye gaze System must be
operated in an environment
infrared light.
The System works best away
from windows, and in a room
lit with fluorescent or mercury-
vapor lights, which are low in
infrared.
It is a sophisticated system with
a high tracking rate and excellent
working range.
It can accommodate rapid or
involuntary head movements
Intelligaze uses the latest
camera technology, very
sophisticated image processing
and calibration methods
IntelliGaze IG-30IntelliGaze IG-30
ADVANTAGESADVANTAGES It helps the user to generate text on a computer.
Can construct words and sentences that can be spoken
aloud by the system.
It helps the user to answer/dial a call
It helps the user to operate his environment.
The user can be a keyboard/mouse and operate a system.
DISADVANTAGESDISADVANTAGES The high cost of eye tracking equipment
The limitation that gaze communication applications
may only work with a particular dedicated eye tracking
device
Finally that eye tracking devices are often hard to
use and require experts to operate them.

CONCLUSIONCONCLUSION
The main reason for eye-gaze based user interfaces
being attractive is that the direction of the eye-gaze can
express the interests of the user-it is a potential porthole
into the current cognitive processes-and communication
through the direction of the eyes is faster than any other
mode of human communication.
