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-

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.
