#### What is Think2Switch™?
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 with 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.

**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 Scenes?
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 devices?
Yes.
Think2Switch™ works with Apple [HomeKit](/think2switch-knowledge-guide/setup-guide/control/output-options/homekit-output.md) smart plugs and switches.
You must first set up the device in Apple’s [Home app](/think2switch-knowledge-guide/setup-guide/control/output-options/homekit-output.md#step-1-add-your-device-in-the-home-app).
***
#### Do I need a Home hub?
Some HomeKit devices need a Home hub.
You can use:
* Apple TV
* HomePod
If your device already works in the Home app, you’re likely set.
***
#### Can Think2Switch™ control computers?
Yes, using [Keyboard Outputs](/think2switch-knowledge-guide/setup-guide/control/output-options/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 voice?
Yes.
The voice comes from your iOS Accessibility → Spoken Content settings. Learn more [here](https://support.apple.com/en-ca/guide/iphone/iph96b214f0/18.0/ios/18.0).
You can change:
* Voice
* Speed
* Pitch
* Volume
