Getting Started

Launching Motion Trainer

1. On the desktop, locate the Motion Trainer shortcut icon:

   • It will be labeled MotionTrainer.

2. Double-click the icon to launch the application.

3. When the application launches, you should see the following splash screen.

4. Click the arrow to continue.

Configuring Game Settings

Next, you should be navigated to the Settings Page. The Settings Page allows you to configure the different experimental games:

• Balloon Game – A movement-sensitivity game where users must keep their head movement within a gradually shrinking threshold.

• Fixation Game – Encourages the subject to remain still and focus for a given duration.

• Video Game – Plays a video file if the subject stays still; pauses if they move too much.

Each game has a few tunable parameters (like movement tolerance and duration), but for now, you can use the defaults to get started.

Press "Done" to begin the session after configuring your games.

Game Selection Screen

After saving your settings and clicking Done, you'll arrive at the Game Selection Screen, where you can choose which game to run:

• Blow Up the Balloon Inflate a balloon by pressing a button while staying still. The balloon grows while movement stays within tolerance and deflates if the subject moves too much.

• Stay Still A fixation-style task. The subject must remain still for a fixed period to succeed.

• Watch Video Plays a video file when the subject remains still. Movement pauses playback.

To change game parameters, click Settings to return to the previous configuration screen.

🎈 Blow Up the Balloon

In this game, the participant inflates a balloon by pressing a button on a handheld device (e.g., a button box). With each button press:

• The balloon grows slightly

• The tolerance for movement decreases, making it harder to stay still as the game progresses

Objective

• Inflate the balloon until it pops — this counts as a successful trial!

• If the participant moves outside the allowed tolerance, the balloon deflates and they are given a chance to try again

How It Works

• The movement tolerance begins at the “Movement Tolerance Start” value (set in the Settings Page)

• It gradually scales down to the “Movement Tolerance End” as the balloon inflates

• Movement is monitored continuously, so the participant must press carefully and remain still

✳️ Stay Still

In this game, the participant is shown a fixation graphic on screen and must remain completely still for a set amount of time.

Objective

• Stay still for the full duration (set via Fixation Duration in the Settings Page)

• If movement exceeds the allowed tolerance (set via Movement Tolerance), the trial fails and the participant is prompted to try again

• If they successfully remain within tolerance for the entire duration, the trial is a success

How It Works

• The fixation graphic remains visible on screen throughout the task

• A fixed movement threshold is used (does not change over time like in the balloon game)

• The trial ends automatically after either a success or a failure

📺 Watch Video

In this game, a video (e.g., a short animated clip) plays while the participant remains still. It pauses whenever movement exceeds a configured threshold and resumes once the participant is still again.

Objective

• Watch the full video without interruption

• If the participant moves too much, the video pauses

• A message saying “Stay still!” appears as feedback

• Once the participant’s movement falls back within the tolerance, the video automatically resumes

How It Works

• The video file is selected on the Settings Page

• A fixed movement tolerance (in mm) is configured for this game

• There is also a timeout value — if the participant doesn’t return to stillness within this time, the session can be stopped or retried
