00:00:00.000 --> 00:00:08.820


00:00:08.820 --> 00:00:11.570
PRESENTER: Tobii Dynavox
software is continuously

00:00:11.570 --> 00:00:13.850
improving, so there may
be slight differences

00:00:13.850 --> 00:00:17.810
between the actual software
and our training materials.

00:00:17.810 --> 00:00:21.950
Control is an intuitive way of
interacting with your computer

00:00:21.950 --> 00:00:24.230
using eye tracking.

00:00:24.230 --> 00:00:27.180
Designed for people with
conditions such as ALS,

00:00:27.180 --> 00:00:30.210
cerebral palsy, and
spinal cord injuries,

00:00:30.210 --> 00:00:33.290
Control makes it easy
to navigate and control

00:00:33.290 --> 00:00:39.050
your computer using only your
eyes with complete independence.

00:00:39.050 --> 00:00:41.770
You might be wondering how
does eye tracking work?

00:00:41.770 --> 00:00:44.660


00:00:44.660 --> 00:00:47.450
First, the eye tracker at
the base of the computer

00:00:47.450 --> 00:00:52.070
sends out near-infrared light,
which is reflected in your eyes.

00:00:52.070 --> 00:00:55.790
Those reflections are picked up
by the eye tracker's cameras.

00:00:55.790 --> 00:00:58.320
Through advanced filtering
and calculations,

00:00:58.320 --> 00:01:01.490
the eye tracker determines where
you're looking on the screen,

00:01:01.490 --> 00:01:03.010
putting you in control.

00:01:03.010 --> 00:01:05.690


00:01:05.690 --> 00:01:08.040
Tobii Dynavox eye
tracking technology

00:01:08.040 --> 00:01:11.830
can track one or both eyes
across a variety of conditions

00:01:11.830 --> 00:01:15.550
having overcome barriers like
bright sunlight, glasses,

00:01:15.550 --> 00:01:20.520
head movement, and positioning.

00:01:20.520 --> 00:01:24.520
Control introduces a concept
called interaction first,

00:01:24.520 --> 00:01:26.760
which mimics the
natural way you would

00:01:26.760 --> 00:01:29.130
use a computer with a mouse.

00:01:29.130 --> 00:01:31.800
This means you first navigate
to the object on screen

00:01:31.800 --> 00:01:34.595
that you want to interact
with by looking at the icon.

00:01:34.595 --> 00:01:37.530


00:01:37.530 --> 00:01:39.480
And then choose
what function you

00:01:39.480 --> 00:01:42.750
want to perform whether that's
right click, double click,

00:01:42.750 --> 00:01:44.730
or something else.

00:01:44.730 --> 00:01:47.350
To open the Google Chrome
browser, for example,

00:01:47.350 --> 00:01:51.240
you would activate the
double click option.

00:01:51.240 --> 00:01:53.550
The gaze trace
provides a clear visual

00:01:53.550 --> 00:01:56.010
of where you are
looking on the screen.

00:01:56.010 --> 00:01:58.380
This trace follows
your gaze, locking

00:01:58.380 --> 00:02:00.090
if a fixation is detected.

00:02:00.090 --> 00:02:03.750
This happens when you stare
at one spot long enough.

00:02:03.750 --> 00:02:06.140
To unlock, simply
move your gaze away.

00:02:06.140 --> 00:02:11.640


00:02:11.640 --> 00:02:15.210
But to interact, select the
activator icon to bring up

00:02:15.210 --> 00:02:18.440
the interaction menu.

00:02:18.440 --> 00:02:22.070
Let's take a closer
look at this menu.

00:02:22.070 --> 00:02:24.450
Every time you select
the activator icon,

00:02:24.450 --> 00:02:27.330
the interaction menu opens
in the center of your screen

00:02:27.330 --> 00:02:28.730
like this.

00:02:28.730 --> 00:02:31.580
Notice that a magnified
image of the selected area

00:02:31.580 --> 00:02:36.380
is displayed in the middle with
a menu options surrounding it.

00:02:36.380 --> 00:02:39.590
This centralized radial
menu improves eye tracking

00:02:39.590 --> 00:02:42.560
accuracy and efficiency.

00:02:42.560 --> 00:02:44.660
You'll find all of your
main interaction functions

00:02:44.660 --> 00:02:50.330
in this menu including
double click, left click,

00:02:50.330 --> 00:02:56.030
scroll, right click,
click and drag,

00:02:56.030 --> 00:03:00.140
opening an on screen
keyboard, and adjust target

00:03:00.140 --> 00:03:04.250
for fine tuning your
initial selection.

00:03:04.250 --> 00:03:05.960
Let's watch how
easy it is to use

00:03:05.960 --> 00:03:08.710
the tools in computer control
to navigate your computer.

00:03:08.710 --> 00:03:12.800


00:03:12.800 --> 00:03:16.070
Imagine you want to look
up today's weather online.

00:03:16.070 --> 00:03:20.390
First, fix your gaze on
the Google Chrome icon.

00:03:20.390 --> 00:03:24.570
Select the activator
icon to open your menu

00:03:24.570 --> 00:03:26.555
and then choose double click.

00:03:26.555 --> 00:03:30.690


00:03:30.690 --> 00:03:33.720
Now that your browser
is open, fix your gaze

00:03:33.720 --> 00:03:35.970
on the address bar.

00:03:35.970 --> 00:03:41.340
Again, select the activator
icon and choose keyboard

00:03:41.340 --> 00:03:42.230
to enter text.

00:03:42.230 --> 00:03:46.530


00:03:46.530 --> 00:03:50.250
Notice how word prediction
makes this process easy.

00:03:50.250 --> 00:03:53.490
Select enter on the
keyboard to start the search

00:03:53.490 --> 00:03:56.640
and then close the keyboard.

00:03:56.640 --> 00:03:59.100
To scroll through
your result options,

00:03:59.100 --> 00:04:01.380
fix your gaze anywhere
on the screen,

00:04:01.380 --> 00:04:05.790
select the activator
icon, and select scroll.

00:04:05.790 --> 00:04:07.410
Look toward the
bottom of your screen

00:04:07.410 --> 00:04:11.530
to start scrolling down to
slow down the scrolling speed,

00:04:11.530 --> 00:04:17.250
keep your gaze closer
to the scroll icon

00:04:17.250 --> 00:04:18.739
or look up to go back.

00:04:18.739 --> 00:04:23.040


00:04:23.040 --> 00:04:27.960
When you have found the website
you want, close the scroll tool.

00:04:27.960 --> 00:04:31.910
Now fix your gaze on the link,
select the activator icon,

00:04:31.910 --> 00:04:33.205
and select left click.

00:04:33.205 --> 00:04:37.490


00:04:37.490 --> 00:04:39.680
Now you're ready
to read the weather

00:04:39.680 --> 00:04:43.400
and you did everything
with your eyes.

00:04:43.400 --> 00:04:45.590
For more options
with Control, simply

00:04:45.590 --> 00:04:50.630
gaze down out of the screen area
to bring up the off screen menu.

00:04:50.630 --> 00:04:53.600
Here you can access
the app switcher,

00:04:53.600 --> 00:04:59.330
enable continuous click,
pause eye gaze, and even more

00:04:59.330 --> 00:05:01.940
like adjusting settings and
calibrating the software

00:05:01.940 --> 00:05:02.530
to your eyes.

00:05:02.530 --> 00:05:05.690


00:05:05.690 --> 00:05:08.240
Control even provides
quick start guides

00:05:08.240 --> 00:05:10.520
right within the
software to orient you

00:05:10.520 --> 00:05:13.580
to all the controls available.

00:05:13.580 --> 00:05:16.430
All in all, Control
provides eye gaze users

00:05:16.430 --> 00:05:18.830
with speed and
precision, reduced eye

00:05:18.830 --> 00:05:21.920
fatigue, and more
successful interactions.

00:05:21.920 --> 00:05:24.050
The bottom line
is Control allows

00:05:24.050 --> 00:05:27.080
you to use the apps
you choose and pursue

00:05:27.080 --> 00:05:30.350
the goals that matter to you.

00:05:30.350 --> 00:05:35.350
