# 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.
The Motion Trainer splash page shows the version (v1.0) and an arrow button to enter the application.
## 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.
The “Game Settings” page of the Motion Trainer Application. Sections include: Balloon Game, Fixation Game, and Video Game. The upper right corner shows that the current settings are the default.
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.
The “Select the game you would like to play” page of the Motion Trainer application. Options include: “Blow Up the Balloon”, “Stay Still”, “Watch Video”, and “Settings”.
## 🎈 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
An example of the "Blow Up the Balloon" game. A white background contains a small image of a nail toward the top of the screen, and a balloon below.
## ✳️ 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
An example of the "Stay Still" game. A black fixation cross is displayed over a white background.
## 📺 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
An example of the "Watch Video" feature of Motion Trainer. A default childrens video is shown on screen.
