What is a brain-computer interface?

Brain-computer interfaces (BCIs) let you control things using only your "thoughts".

They work by detecting and interpreting electrical signals from your brain, through special sensors placed on your head, and translating those signals into a command to control some output device, like a computer. BCIs can help people with physical limitations who may struggle to use other types of access methods like keyboards, mice, adaptive switches, etc.

Frequently Asked Questions

What is Think2Switch™?

Think2Switch™ is a non-invasive brain-computer interface (BCI) system that translates brain activity into actionable commands, enabling individuals to control devices using thought alone. No movement required!

When paired with the Muse S Athena headset, the Think2Switch™ app allows users to communicate, make choices, and interact with their environment—without requiring physical movement or speech.

How does Think2Switch™ work?

Think2Switch™ operates through a simple, guided process:

  • The user wears the Muse S Athena headset, a soft, non-invasive device with sensors positioned on the forehead and right above the ears.
  • The system is calibrated to distinguish between an “active command” and a resting state.
  • The app interprets these brain signals in real time.
  • These recognized signals are translated into commands that activate selected outputs.

For example, a trained active command can be used to turn on a light, make a selection, or control media—without physical interaction.

For more detailed guidance, please refer to the Think2Switch™ Knowledge Guide.

What is an active command?

An active command is a consistent mental signal that triggers a selected output. It is the foundation of how Think2Switch™ functions.

During calibration, users are asked to think of a consistent command (such as a word, phrase, or imagined movement). Once trained, Think2Switch™ detects this signal and uses it to activate functions such as:

  • Communicating a word or phrase
  • Making a selection
  • Controlling devices or media

The command does NOT need to be a word. Any consistent internal thought can be used, provided it can be reproduced reliably.

Quick Guide for Calibration & What You Can Do With Think2Switch™

What is Think2Switch™ and How to Calibrate for Success

Does Think2Switch™ read my thoughts?

No. Think2Switch™ does not read or interpret your inner thoughts.

When you think, your brain generates electrical brain signals and this is what Think2Switch™ detects and interprets as your active command. It does not recognize specific words or ideas—only the unique brain activity pattern associated with a user’s command.

Who is Think2Switch™ for?

Think2Switch™ was designed primarily for individuals with severe physical and communication disabilities, particularly children who face significant barriers to interaction and participation.

The system, however, is used by adults and individuals with a range of neurological conditions, supporting communication, independence, and engagement in everyday activities.

What do I need to use Think2Switch™?

To get started, you will need:

  • The Think2Switch™ app
  • The Muse S Athena headset

Optional integrations:

  • HomeKit Output: Control compatible smart devices (e.g., lights or appliances) using HomeKit-enabled smart plugs.
  • Keyboard Output: Send keyboard inputs to a connected computer or tablet to control applications, games, or media.

What can you control with Think2Switch™?

Think2Switch™ enables control of devices and applications that respond to simple on/off or input-based commands. See examples here:

Does Think2Switch™ work with other assistive technologies?

Think2Switch™ currently supports select integrations, including compatibility with devices such as Tobii Dynavox systems.

We are actively expanding compatibility with additional assistive technologies, including AAC devices and platforms such as Alexa, Android and Google Home.

For specific integration inquiries, please contact our team at info@possneuro.com.

How long does it take to learn and use Think2Switch™?

Initial setup and calibration typically take 5–10 minutes.

Learning to use Think2Switch™ is a personalized process. Some users respond quickly, while others benefit from shorter, repeated sessions over time. Progress varies by individual, and there is no fixed learning timeline.

Is Think2Switch™ backed by research?

Yes. Think2Switch™ is grounded in neuroscience and assistive technology research.

The system is based on the doctoral research of Dr. Dion Kelly, co-founder and CEO of Possibility Neurotechnologies, which explored how brain-computer interfaces can enable children with severe physical disabilities to participate in meaningful and purposeful activities, determined by the child.

How much does Think2Switch™ cost?
  • Think2Switch™ app: approximately $35 USD / month or $350 USD / year
  • Muse S Athena headset: One-time purchase of approximately $475 USD

Does the Muse S Athena headset fit all users?

The Muse S Athena headset is designed to accommodate a wide range of head shapes and sizes.

If fit issues arise, please contact our team for support at info@possneuro.com.

I’m not sure if Think2Switch™ is the right fit. Can I try it first?

Yes. We offer options to help you evaluate whether Think2Switch™ is right for you:

  • The Muse S Athena headset includes a 30-day return policy.
  • The Think2Switch™ app includes a 30-day free trial.

This allows you to explore the system and determine if it meets your needs before committing.

Is Think2Switch™ covered by insurance?

The Muse S Athena headset may be eligible for reimbursement through health spending accounts, depending on your provider.

At this time, the Think2Switch™ app is not covered by insurance and is considered an out-of-pocket expense. We are actively working toward broader coverage options.

Is Think2Switch™ available outside of Canada?

Yes. Think2Switch™ is available globally.

All you need is the Think2Switch™ app and the Muse S Athena headset.

Is Think2Switch™ available in multiple languages?

Not yet. We are actively working to expand language support while ensuring accuracy and usability.

I represent an organization purchasing for multiple clients. What if subscriptions are not permitted?

We recognize that subscription-based payments may not align with institutional procurement policies.

We offer flexible purchasing options, including:

  • Direct invoicing for app licensing
  • Bulk procurement of Muse S Athena headsets
  • Centralized billing for multiple users

This approach allows organizations to avoid in-app subscriptions while maintaining streamlined purchasing and deployment.
