An introduction to the Gaze Interaction on the Tobii ISeries - calibrating the eye tracker, using the track status box, positioning the device, using windows controls and links to other training info

1. Tobii ISeries
INITIAL CALIBRATION AND POSITIONING

2. In this series, you will learn about
 Programming Side Buttons
 Track Status Box
 Distance and Positioning
 Calibration Settings
 Positioning Guide
 Windows Control Types

3. Side Buttons
 On the ISeries, you can program the first two buttons long the left edge of
the device.
 These are typically used for Track Status and Pause, but can be used for
many other functions.

4. How to Program The Side Buttons
 From your desktop, go to ISeries
Control Center (need image of icon)
 Select Button

5. What Do These Terms Mean?
 Track Status Box – a visual cue to help position a device in front of a user
 Calibration Points – the stimulus that a person looks at during a calibration
process
 ISeries Control Center – pink icon on desktop where one can control many
of the hardware and software settings of the device, including
programming side buttons and enabling/disabling eye tracker
 Windows Control – the ability to control the windows desktop using either
Mouse Emulation or Gaze Selection

6. Track Status Box
 The track status box is used to help
position a user in front of the eye
tracker.
 It can be brought up by the user or
carer through Tobii Communicator,
Gaze Interaction Settings or
programmable side button.

7. Optimal Distance and Position
 Optimal Distance is set by lining the
white triangle in the green area of the
bar along the right edge.
 Optimal Position is set by having the
dots (eyes) in the center of the black
box.

8. Calibration Settings – 2, 5 or 9
 When calibrating a person, you can
use 2, 5 or 9 dots
 The more dots you have, the more
data can be used to provide an
optimal calibration
 The fewer dots you have, the quicker
the calibration will go

9. When should I use 2 dots? Or 5? Or 9?
 If you have strong eye control and may be looking to hit many smaller
targets, strive for a 9 point.
 If you are new to eye tracking and are just trying to get some success
quickly, try a 2 point with larger targets.
 Note that you can always recalibrate to improve your accuracy AND
 Eye tracking will get stronger and better with practice!

10. Calibration Settings – Stimulus Size and
Design
 One can change the stimulus size,
type and speed.
 This can make the stimulus easier to
see, more motivating (videos) and
easier to track

11. Positioning Guide – Do I Need It?
 The positioning guide (circled at right)
is a guide that will pop up when the
client may be out of optimal position
and then disappear when the client is
in position.
 Useful for clients to gauge for
themselves where they need to be
positioned

12. Interaction – Fine Tune Use
 On this screen, you can change:
 The activation method – dwell, blink or
switch
 The interaction time
 For dwell, small number is faster dwell
time
 For blink, you have a range for blink
speeds
 For Switch, you have a click duration
setting
 The Visual Feedback – type, color, size
and opacity

13. Windows Control – Mouse Emulation or
Gaze Selection
 On the Windows Control settings
page, you can:
 Set Windows Control to start at boot
(we will speak more to this in a couple
slides)
 Choose between Mouse Emulation
and Gaze Selection
 Note that for interactive games such as
EyeFX and Look To Learn, Windows
Control must be turned on and set to
Mouse Emulation.

14. How do I turn off Windows Control?
 Windows Control can be turned on
and off from within Tobii
Communicator.
 Why?
 For a client whose primary access
method is Eye Tracking, it was designed
to be difficult to ‘accidentally’ close
Windows Control so that the user will
always have some control of the
device.
In Sono Key, use the
“Minimize Sono Key”
button to get to a
Windows Control On/Off
button

17. Do I Need Windows Control On
Startup?
 For a primary Windows Control user, you can set EITHER Tobii
Communicator or Windows Control to start.
 They should not be set to both start on boot.
 For a primary Tobii Communicator user, you can start Tobii Communicator
at start up, and the user can start Windows Control if needed.

18. Apply and OK
 When done, click Apply and OK and you can move into Tobii
Communicator or Windows Control.
