software is continuously
improving, so there may
be slight differences
between the actual software
and our training materials.
Control is an intuitive way of
interacting with your computer
using eye tracking.
Designed for people with
conditions such as ALS,
cerebral palsy, and
spinal cord injuries,
Control makes it easy
to navigate and control
your computer using only your
eyes with complete independence.
You might be wondering how
does eye tracking work?
First, the eye tracker at
the base of the computer
sends out near-infrared light,
which is reflected in your eyes.
Those reflections are picked up
by the eye tracker's cameras.
Through advanced filtering
and calculations,
the eye tracker determines where
you're looking on the screen,
putting you in control.
Tobii Dynavox eye
tracking technology
can track one or both eyes
across a variety of conditions
having overcome barriers like
bright sunlight, glasses,
head movement, and positioning.
Control introduces a concept
called interaction first,
which mimics the
natural way you would
use a computer with a mouse.
This means you first navigate
to the object on screen
that you want to interact
with by looking at the icon.
And then choose
what function you
want to perform whether that's
right click, double click,
or something else.
To open the Google Chrome
browser, for example,
you would activate the
double click option.
The gaze trace
provides a clear visual
of where you are
looking on the screen.
This trace follows
your gaze, locking
if a fixation is detected.
This happens when you stare
at one spot long enough.
To unlock, simply
move your gaze away.
But to interact, select the
activator icon to bring up
the interaction menu.
Let's take a closer
look at this menu.
Every time you select
the activator icon,
the interaction menu opens
in the center of your screen
like this.
Notice that a magnified
image of the selected area
is displayed in the middle with
a menu options surrounding it.
This centralized radial
menu improves eye tracking
accuracy and efficiency.
You'll find all of your
main interaction functions
in this menu including
double click, left click,
scroll, right click,
click and drag,
opening an on screen
keyboard, and adjust target
for fine tuning your
initial selection.
Let's watch how
easy it is to use
the tools in computer control
to navigate your computer.
Imagine you want to look
up today's weather online.
First, fix your gaze on
the Google Chrome icon.
Select the activator
icon to open your menu
and then choose double click.
Now that your browser
is open, fix your gaze
on the address bar.
Again, select the activator
icon and choose keyboard
to enter text.
Notice how word prediction
makes this process easy.
Select enter on the
keyboard to start the search
and then close the keyboard.
To scroll through
your result options,
fix your gaze anywhere
on the screen,
select the activator
icon, and select scroll.
Look toward the
bottom of your screen
to start scrolling down to
slow down the scrolling speed,
keep your gaze closer
to the scroll icon
or look up to go back.
When you have found the website
you want, close the scroll tool.
Now fix your gaze on the link,
select the activator icon,
and select left click.
Now you're ready
to read the weather
and you did everything
with your eyes.
For more options
with Control, simply
gaze down out of the screen area
to bring up the off screen menu.
Here you can access
the app switcher,
enable continuous click,
pause eye gaze, and even more
like adjusting settings and
calibrating the software
to your eyes.
Control even provides
quick start guides
right within the
software to orient you
to all the controls available.
All in all, Control
provides eye gaze users
with speed and
precision, reduced eye
fatigue, and more
successful interactions.
The bottom line
is Control allows
you to use the apps
you choose and pursue
the goals that matter to you.
