Think2Switch™ lets you use your thoughts to control things like sounds, words, pictures, apps, or smart home devices. \ It works by learning two brain states: * Rest (nothing should happen) * Command (make something happen) *** #### What is a command? A **command** is the thought you use to activate an output. A command can be: * A word in your head (like “go” or “yes”), or * A movement attempt (like trying to press or push) \ What matters most is using the same command **consistently**. *** #### What command should I try first? Many people start by repeating a short word in their head, such as: * “Go” * “Yes” Others do better with a movement attempt, like: * Trying to press a button * Trying to push something \ There is no right or wrong choice. You can change your command later if needed. *** #### Can I change my command? Yes. You can try different commands to see what control feels like with each one. For example, you might want to compare: * A word command * A movement attempt command \ This can help you decide which command works best for you. **Important to know:** Each time you change your command, you should **reset your calibration** and practice again. This helps Think2Switch™ learn one command at a time. If you don’t reset, the app may get confused because it is seeing different thoughts mixed together. {% hint style="info" icon="lightbulb" %} **Good to Know** * Trying different commands is normal * You can take your time to find what works best * Resetting calibration is part of the process {% endhint %} *** #### Why is calibration important? Calibration teaches Think2Switch™: * What your brain looks like at rest * What your brain looks like when you use your command This helps the app tell the difference between “do nothing” and “do something.” \ If calibration is skipped or rushed, control may feel harder. *** #### What should I do during rest? When practicing rest: * Sit comfortably * Keep your eyes open * Stay as still as you can * You don’t need to think about anything special \ If your mind wanders, that’s okay. *** #### What should I do during command? During a command trial: * Use the same thought each time * Keep it simple * Don’t switch between different ideas **Consistency matters more than effort.** *** #### What do the waves on the screen mean? The waves show how clearly the app is seeing your command. * Big waves = strong signal * Small waves = signal not clear yet \ Low waves are common when starting. You can practice again if needed. *** #### What does accuracy mean? Accuracy shows how well Think2Switch™ can tell the difference between Rest and Command. * Around 70% or higher usually works well * Lower scores are common at first \ Accuracy is only a guide. **The best test is how control feels when you try it.** *** #### What are outputs? Outputs are what happen when you use a command. For example, an output can: * Say a word * Play a sound * Show a picture * Press a keyboard key * Turn on a smart plug \ Each output appears as a square on the Control tab. *** #### What are ccenes? A scene is a group of outputs used together. \ Scenes help organize outputs by: * Activity (Food, Mood) * Place (Kitchen) * Purpose (Communication, Play) \ You can switch between Scenes anytime. *** #### How do I activate an output? 1. Tap Start 2. Perform your command 3. When the signal goes above the dashed line, the output activates To stop: * Stop performing your command * Return to Rest * Or tap Stop *** #### Can I activate outputs by touching them? Yes. \ You can tap an output to activate it manually. This is helpful for testing or setup. *** #### What are control modes? Control modes decide how commands control outputs. Think2Switch™ chooses the best mode automatically based on: * How many outputs you have * How many commands you use \ You don’t need to memorize the modes to use the app. *** #### Do I need two commands? No. Many people do very well with one command. A second command can give more control options, but it’s optional and can be added later. *** #### What devices do I need? You need: * An iPhone or iPad (2019 or newer recommended) * A compatible Muse headset (Muse 2 or Muse Athena) Muse Athena is recommended for children or long wear. *** #### Can Think2Switch™ control smart plugs? Yes. Think2Switch™ works with Apple [HomeKit](/think2switch-knowledge-guide/setup-guide/control/scenes/homekit-output.md) and Matter compatible smart plugs and switches. See [HomeKit Outputs](/think2switch-knowledge-guide/setup-guide/control/scenes/homekit-output.md) for more information. *** #### Do I need a Home hub? Some HomeKit and Matter accessories need a Home hub. You can use: * Apple TV * HomePod If your device already works in the Home app, you’re likely set. See [HomeKit Outputs](/think2switch-knowledge-guide/setup-guide/control/scenes/homekit-output.md) for more information. *** #### Can Think2Switch™ control computers? Yes, using [Keyboard Outputs](/think2switch-knowledge-guide/setup-guide/control/scenes/keyboard-output.md). Think2Switch™ can act like a Bluetooth keyboard to: * Play/pause videos * Control games * Navigate apps \ You’ll need to pair your iPhone or iPad with the computer once using Bluetooth. *** #### Why isn’t my Keyboard Output connecting? If you see an exclamation mark (!): * Bluetooth may need to be reset * The device may need to be re-paired \ Make sure: * Bluetooth is on * A Keyboard Output is in the Scene * Only one computer is paired at a time *** #### Why is my Mac or iPad receiving keystrokes without pairing? If devices share the same Apple ID, keystrokes may be sent automatically. To prevent this: * Use a different Apple ID on the device running Think2Switch™ *** #### Can I change the voices? Yes, see [Control Settings](/think2switch-knowledge-guide/setup-guide/control/control-settings.md). The app uses voices from your iOS Accessibility settings.
