Targeting

I can gaze at a particular part of the screen to make something specific happen 

 

Learning

At this step we are learning that performing a “mouse-over” action with our eyes will make an action happen. This step really focuses on training the learner to focus their gaze on a part of the screen that they have chosen.  

 

Communication

This is the first step where the learner is actively selecting what they want to say with their eyes! Since audio is only heard if the learner looks at a specific part of the screen, communication can be based around what the learner has decided to look at. The communication partner can then respond to the audio that the learner has played with their eyes.   

 

Calibration

For this step the learner needs as good a calibration as possible with as many calibration points as they can manage. How to do the calibration can be different for different pieces of software, check out the Support & Training pages for your software for videos about calibration.  

 

Give it a Try

Activities in this section are free to try if you have a Tobii Dynavox eye gaze device (separate or integrated eye tracker).  

Practice 1: Catch Me

 

Objectives

  • We are learning to actively target gaze on specific areas of the screen
  • We are learning that targeting our gaze leads to an action

 

Get Ready

To get up and running with this activity you will need: 

 

Let’s Go!

Following these steps makes it simpler to get going with the activity. 

  1. Connect your eye tracker/ start your device.
  2. Depending on eye gaze software:
    • Open Gaze Point, start it with the Play button and turn off Mouse Click. Hide the Mouse Cursor.
    • Or open Windows Control and select Sticky Move Cursor.
      • To select this option, start by going to Settings -> Taskbar -> Tasks -> Change and turn on Place Cursor.
      • Go to Taskbar -> Selection and turn on Tertiary Selection.
      • Exit Settings and gaze at the taskbar to activate the tertiary selection.
      • In the popup that shows, select the Sticky Move Cursor task.
    • Or open Classic Gaze Interaction Software.
      • In Settings, select Mouse Emulation.
      • Exit Settings and select Mouse Cursor.
  3. Click here to play Catch Me.
  4. Turn up the volume and watch out for the spider eyes on the screen.
  5. The user can catch the spider by directing their gaze towards it.
  6. Key vocabulary at this stage can be built around the circle that appears on-screen that indicates where the user is looking.

 

Say

Use phrases such as these to promote communication! 

  • “I can see that you are looking at the bottom of the screen. You are close to the spider!”
  • "You looked at the spider and I heard sounds play!"

 

Top Tips

Looking for extra help with the activity?

  • If you feel that accuracy is a little off, why not try calibrating your device?
  • Encourage the learner to look at all parts of the screen by modeling words from different areas of the screen

 

Look For

Simply revealing the spider shows that the user has successfully gazed at the correct place on the screen. The spider can escape though, so catching the spider more than once would be a good indication of success!

 

Go Beyond Examples

 Here are some extra ways to practice the skills connected with this step. 

Practice 2: Painting!

 

Objectives

  • We are learning to actively target gaze on different items and colours to give different results
  • We are learning new vocabulary connected to the scenes we look at

 

Get Ready

To get up and running with this activity you will need: 

 

Let’s Go!

Following these steps makes it simpler to get going with the activity. 

  1. Connect your eye tracker/ start your device.
  2. You don't need to start your gaze software to use Communicator 5 with eye tracking, it just needs to be installed. 
  3. Open Communicator 5 and the Sono Primo page set, found in All Page Sets -> Emerging Communication -> Add-On Products.
  4. Make sure the volume is turned up!
  5. Open “Paint Activity”.
  6. The user can select the scene of their choosing by gazing at it.
  7. Different elements of the chosen scene can then be painted by gazing at a colour to choose it before gazing at the object to paint it with the chosen colour.
  8. Communication can be fostered by discussing the different scenes, the content within the scenes and the different colours. This can be instigated by the care-giver in response to what items and colours the user is painting.

 

Say

Use phrases such as these to promote communication! 

  • “I see that you painted the barn blue. Blue is my favourite colour!”
  • "I can see the a sun on the screen. The sun is in the corner of the screen."

 

Top Tips

Looking for extra help with the activity?

  • Encourage the learner to look at all parts of the screen by modeling words from different areas of the screen

 

Look For

Are any items within the scene painted? Then we can consider that to be a success. Are all items within the screen painted? Fantastic! 

 

Practice 3: Look & Listen

This practice activity is for the Windows version of Tobii Dynavox Snap Scene. Try for free by downloading the Snap Scene LITE app or buy the full version. Note that Snap Scene is also available for iPad on the App Store (only Touch access, no Eye tracking).

 

Objectives

  • We are learning to understand the connection between what is looked at and the audio that plays
  • We are learning new vocabulary from the selected scenes

 

Get Ready

To get up and running with this activity you will need: 

 

Let’s Go!

Following these steps makes it simpler to get going with the activity. 

  • Connect your eye tracker/ start your device.
  • Depending on eye gaze software:
    • Open Gaze Point, start it with the Play button and turn on Mouse Click. Hide the Mouse Cursor.
    • Or open Windows Control and select the Sticky Left Click task.
      • To select this task, start by going to Taskbar -> Selection and turn on Tertiary Selection (unless it's already on).
      • Exit Settings and gaze at the Left Click task on the taskbar to activate the tertiary selection.
      • In the popup that shows, select the Sticky Left Click task.
    • If you use Classic Gaze Interaction Software, it only needs to be installed, you don't need to start it.
  • Open Snap Scene.
  • Explore Snap Scene and when you feel comfortable, upload a picture from your computer.
  • Add “hotspots” around different parts of the scene. For example, draw a hotspot around a friend or family member performing an action such as throwing.
  • Add audio to the hotspot that describes what is happening, such as “throw the ball”.
  • Make sure the volume is turned up.
  • Encourage the learner to explore the scene and listen for audio!

 

Say

Use phrases such as these to promote communication:

  • "You looked at the scene and said 'throw the ball'. I want to throw the ball too. Let's throw the ball!"

 

Top Tips

Looking for extra help with the activity?

  • Download the Pathways app for iPad, a free supplementary learning app for Snap Scene!
  • Choose familiar locations, people and situations for the visual scenes to give extra context and meaning!

 

Look For

Hearing audio associated with different parts of the visual scene represents that the learner has targeted their gaze effectively.

Words to Remember

Calibration

In order for eye tracking to work as accurately as possible, the eye tracker must know more about your eyes. This is why you need to do a calibration. During the calibration the eye tracker measures how your eyes reflect light. The calibration is done by following a point, video or other graphic element that moves across the screen. This calibration data is then combined with our unique 3D model of a human eye, and together they give you an optimal eye tracking experience.

The learner can calibrate within the settings of Gaze Point, Windows Control or Classic Tobii Gaze Interaction Software. 

Modeling

Modeling is when the communication partner talks to the learner while also pointing/ selecting keywords on the learner's AAC device. This helps develop the learner's understanding of both language and symbols.
