New Eyegaze Edge

July 28, 2008

L.C Technologies is about to introduce the new Eyegaze 
system. It's called the Eyegaze Edge. The price is 
substantially lower, the camera is smaller, the performance 
is as good or better than their "blue box" system, and it 
can be configured many ways. This revolutionary system at 
this price will allow for pre-approved assignment from 
Medicare. 
 
 
 
 
 
The system offering right now is using the MAC mini (loaded 
with WIN XP) which is tiny but powerful. The price has 
substantially dropped, and comes with approximately 3 hours 
of installation and training time. Option prices, travel 
costs and extra consulting are unchanged.  
 
 
 
 
 
The price of a turnkey Eyegaze Edge system with the MAC 
mini is $8700. USD. It includes the camera, camera 
mounting bracket, and software. It doesn't include monitor 
arm, the monitor arm is available separately for an 
additional $234. USD, or you can supply one that is 
available. 
 
 
 
 
 
 
The Eyegaze System is a direct-select vision-controlled 
communication and control system. An Eyegaze user can 
perform a broad variety of functions including speech 
synthesis, environmental control (lights and appliances), 
typing, operating a television, and running both mouse- and 
keyboard-controlled applications on a second PC. Selections 
are made by looking at boxes or "keys" displayed on the 
Eyegaze System's screen. Nothing is attached to the user. 
Eyegaze programs vary from simple teaching programs, where 
the screen is divided into two or four large boxes (keys), 
to entire on-screen computer keyboards with 75 or more 
5/8-inch square keys. Eyegaze users range in age from 5 
years to 80 years old. 
 
 
 
The Eyegaze System uses the pupil-center/corneal-reflection 
method to determine where the user is looking on the 
screen. An infrared-sensitive video camera, mounted beneath 
the System's monitor, takes 60 pictures per second of the 
user's eye. A low power, infrared light emitting diode 
(LED), mounted in the center of the camera's lens 
illuminates the eye. The LED reflects a small bit of light 
off the surface of the eye's cornea. The light also shines 
through the pupil and reflects off of the retina, the back 
surface of the eye, and causes the pupil to appear white. 
The bright-pupil effect enhances the camera's image of the 
pupil and makes it easier for the image processing 
functions to locate the center of the pupil. The computer 
calculates the person's gaze point, i.e., the coordinates 
of where he is looking on the screen, based on the relative 
positions of the pupil center and corneal reflection within 
the video image of the eye. Typically the Eyegaze System 
predicts the gaze point with an average accuracy of a 
quarter inch or better.
