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

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