nous™ Blink is now available in the USA via Cadan Assistive Technologies!

Blink to Click

For people who have physical disabilities which affect all their limbs it can be difficult to control a computer nous™ lets people control assistive software by blinking. It only uses your intentional blinks, so you can still blink comfortably.

A wearable headset detects intentional blinks, while our software uses them to 'click' on a computer. 

nous™ is a unique switch access method, as it is affordable, simple, user friendly and faster than other blink switches

How it works

Co-designed with people who have disabilities & Built with access in mind

  • People with access needs

    nous™ is an assistive solution that helps people with a range of conditions such as:

    - motor neurone disease
    - cerebral palsy
    - spinal cord injury
    - locked-in syndrome

    Combined with a headset that detects your eye-blinks, nous™ software learns your natural blinking style. Then you can use intentional blinks to control a range of assistive software applications to communicate, play games and connect. 

    Our solution only uses your intentional blinks, so you can blink normally while you use it.

  • Family / Caregivers

    If you are a family member or caregiver of someone who is unable to communicate or use a computer because of a disability, nous™ can help.

    Combined with a computer and assistive software, nous™ acts like a switch which allows your loved one to communicate and interact through their computer.

    If they can intentionally blink, or learn to do so, then they can use nous™.

  • Healthcare professionals

    Are you a health professional, such as a Speech and Language Therapist/Pathologist or Occupational Therapist, who works with people who are unable to communicate with spoken language or use existing access technologies? If so, nous™ may be an option.

    You can think of nous™ as a switch access method that offers access to assistive software through blinks.

    By using nous™ you can help your clients or patients to communicate with you and their loved ones, opening them up to more opportunities.

nous™ works seamlessly with your software

nous™ can be used with all of the most popular communication apps available on Windows OS, such as Tobii Dynavox Communicator 5, PRC NuVoice and SmartBox Grid 3.

nous™ can also be used with other software applications that can be used with switch interfaces, such as the Windows on-screen keyboard, and cause and effect games.

Frequently Asked Questions

What is nous™?

nous™ is a switch access method that simply uses your intentional/purposeful blinks to access a computer. nous™ is both hardware and software. The hardware is a soft headband that houses the sensors which measure your blinks. The software uses the blink information from these sensors and uses them as a switch access method for computer applications

What is a Switch Access Method?

A switch access method refers to a specialist way of accessing a computer, mobile device or communication aid using a simple switch, in the place of the more varied interfaces such as keyboards and touch screens. Switches are usually used by people with physical disabilities, who can't use more traditional access methods.  

A switch is a simple device that has two states – on and off. They come in a variety of different shapes and sizes and are operated in different ways. Often this is through a push motion but you can also find ones that you grasp, pull, sip and puff or even throat vibrations.

What is blink ‘Calibration’?

Everyone’s blinks are different. Infact, on any given time or day, even your own blinks will vary. We need to understand what your “blink signal” looks like before you start using nous™. And to do this we need to go through a calibration exercise. Calibration is the process of determining the correct threshold for your blinks. It ensures that you get the most accurate experience when using blinks to control the software.

We want you to still be able to blink naturally, otherwise it will be very uncomfortable trying to use nous™.

I have access needs. How can nous™ help?

nous™ might be a useful switch access method for you, if existing  assistive technologies are too difficult to use. They may be difficult to use because you may not have the physical means of accessing them, or they may be tiring too use. Because nous™ only requires you to have the ability to blink reliably, it could be the perfect solution for you. 

As a carer what do I need to know?

If you care for an individual with an access need, nous™ may enable them to comfortably and reliably access a computer. This will help them communicate with you, and increase their autonomy. 

As a carer, you will need to assist in placing the headband on, and turning it on. You will also need to launch nous™ and go through the calibration process with them. We've made the process as user-friendly as possible, but if you have any concerns or requests, please don't hesitate to email us 

How can nous™ help health professionals?

If you are a health professional, such as a Speech and Language Therapist or Occupational Therapist, nous may help your clients who have very high access needs. For instance, your clients who cannot use any existing switch access methods, or experience great difficulty/discomfort using them.

nous™ only needs your client to be able to blink reliably! It's simple, reliable and comfortable. 

What do I need to use nous™?

You will need a Window OS computer or tablet, our nous™ software and the blink-detection headband that comes with nous™.

Does nous™ work on all computers?

nous™ currently only works on Windows operating systems. We hope that in the near future we will expand to other operating systems, such as Mac OS and iOS. Watch this space!

What software can nous™ control?

nous™ integrates with existing communication software. Currently, we integrate with the most widely used Windows-based communication software: Tobii Dynavox Communicator 5, PRC NuVoice, SmartBox Grid 3 and Clicker 7.

It can also work out of the box, as a switch access method for the Windows on-screen keyboard.

We’re still learning about other useful software applications that our customers may want to use with nous™. If there are any other windows-based software applications that you would like to connect with, please email us, and we will get back to you.

Can I try nous™ before I buy it?

Free trials are currently only available in New Zealand and Australia.

For other locations please check with our international partners.

If you are interested in partnering with us to enable trials for your clients, please contact us by emailing

How do I buy nous™?

You can purchase nous™ through our website or through our international partners.

What if I have trouble using nous™?

Although nous has been designed to work as soon as it arrives on your door-step, it can take a while to get the hang of using your blinks as a computer access method. For some people it takes minutes, for others it can take several months. Hopefully, you will have a therapist who has designed a learning program for you, so that you can see the benefits of nous as soon as possible. 

We are improving the nous product and performance everyday. If you have any ideas on ways that we could improve it, please email us. 

If you're not entirely satisfied with nous, and practice has not helped, them please email us so we can determine what the best solution is, and if a return is the best option. 

How can my organisation access nous™?

You can request a demonstration of nous™ by emailing us We are actively looking for international distributors.
