Exploring

I make changes happen when I look at different parts of the screen

Learning

Here we learn about cause and effect and that changes happen on-screen depending on where we look. Learning takes place through exploration, where the learner can freely look around and discover what happens when they look at different parts of the screen. When we are doing this we are also learning new vocabulary such as colours in painting activities or the names of different objects in scenes.

 

Communication

Communication at this step can come from the communication partner modelling the use of vocabulary at all areas of the screen. This teaches both navigation around the screen and new vocabulary!   

 

Calibration

For this step the learner needs to do a one point calibration. If possible, a two point calibration would work ever better. Click here for more information about calibration.

 

Give it a Try

Activities in this section are free to try if you have a Tobii Dynavox eye-tracking device. 

Practice 1: Jackson Pollock

Objectives

  • We are learning to paint different parts of the screen with different colours
  • We are learning the names of colours

 

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
  • Open Gaze Point software, start it with the play button, make sure the mouse click is turned on and the curser is hidden
  • Click here to paint!
  • The learner can paint on-screen using the movement of their gaze

 

Say

Use phrases such as these to promote communication! 

  • “I can tell that you are looking at the top of the screen as that is where you are painting!”
  • "I can see lots of different colours on the screen. I like that you changed the colurs with your eyes."

 

Top Tips

Looking for extra help with the activity?

  • The colour of paint changes automatically when the learner dwells their gaze on one point of the screen for a short amount of time. Congratulate the learner for changing paint colour with their eyes!
  • The hidden curser emphasizes the relationship between eye movement and the changes on-screen.
  • Open the Eye Gaze Pathway on the learner's device and on another device to make reading the tips and instructions possible while the learner is attempting the activities.

 

Look For

Can you see different colours in different parts of the screen? Great! The learner has shown that they can paint on-screen and dwell their gaze. 

 

Go Beyond Examples

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

Practice 2: Lights

Objectives

  • We are learning to turn on lights displayed on the screen
  • We are learning to gaze at different parts of the screen

 

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
  • Open Gaze Point software, start it with the play button, hide the mouse curser and turn mouse click off
  • Turn up the volume!
  • Open Sensory Eye FX software and select the “lights” game from the list
  • The learner can explore different parts of the screen with their eyes and see that different lights turn on depending on where on the screen they are looking

 

Say

Use phrases such as these to promote communication! 

  • “I can see that you looked at the top of the screen because a bulb turned on in the same place”
  • “You looked at a lamp on the bottom row and I heard a sound at the same time!”

 

Top Tips

Looking for extra help with the activity?

  • A sound coincides with each light that turns on. Mention that you hear sounds because the learner is causing them to play with their gaze!

 

Look For

A sign of success is if some lights are on at all times, as they turn off automatically after a few seconds!

 

Practice 3: Exploring Scenes

Objectives

  • We are learning to explore a variety of visual scenes and communication grids
  • We are learning new vocabulary associated to visual scenes and communication grids

 

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
  • Open Gaze Point software, start it with the play button and make sure the mouse click is turned on
  • Turn up the volume!
  • Open Sono Primo
  • Encourage the learner to look at the screen. Different grids or visual scenes can be selected depending on where the learner is looking
  • The learner can gaze at different areas of the screen to communicate different things once a grid or scene has been selected
  • The word associated with the part of the screen being looked will be heard through the speakers
  • Respond to what is heard!
  • We are not focusing on learning how to accurately communicate feelings or needs at this point. Let’s simply get used to idea that there are a variety of different grids and scenes that can be used for different purposes.

 

Say

Use phrases such as these to promote communication! 

  • "You said 'play outside'. We played outside yesterday and it was fun. We can play outside again today!"
  • "You said 'blow lots of bubbles'. Now I will blow lots of bubbles! I think it is fun to blow bubbles." 

 

Top Tips

Looking for extra help with the activity?

  • What is communicated at this stage is not important, though try to respond each time the user gazes at a point of the screen to promote the idea that care-giver responses are directly linked to user gaze.
  •  Feel free to give assistance to exit the grid/ scene and encourage the learner to select another

 

Look For

A simple way to assess success in this instance is to witness if the learner has selected a grid/ scene and gazed at some of the options within it. If the learner manages this for several grids/ scenes, even better!

 

Keep Growing

 

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.
