nous™ Wearable Blink Switch

nous™ Wearable Blink Switch


Think “blink to click”.

nous™ is a switch access method that simply uses your blinks to access a computer. For people who have physical disabilities which affect all their limbs and their voice, it can be difficult to access or control a computer. That’s where nous™ comes in- nous™ lets people control assistive software by blinking.

nous™ is both hardware and software. The hardware component is a soft headset that houses the sensors which measure your blinks.

These sensors measure the electrical signals of eye movement, called "electrooculography" or EOG. With nous™, the headset measures the EOG signals produced when a person blinks. Everyone’s blinks are different. Infact, on any given time or day, even your own blinks will vary. The software part of nous™ needs to understand what a person's “blink signal” looks like before they start using it as a switch access method. This ensures that they get the most accurate experience when using blinks to control software applications.

We want people to still be able to blink naturally, otherwise it may be uncomfortable trying to use nous™. So users of nous™ will go through a calibration process that teaches nous™ what a person's intentional/purposeful blinks look like.

Once the calibration is complete, nous™ can be used as a switch access method for Windows OS based computer applications, such as Communicator 5 by Tobii Dynavox, NuVoice by PRC and Grid 3 by Smartbox, as well as other software applications that can be used with switch interfaces. nous™ might be a useful switch access method, if existing assistive technologies are too difficult to use. Because nous™ only requires you to have the ability to blink reliably, it could be the perfect solution.

For additional information, you can find our introduction and tutorial videos on the website here, and videos of nous™ being used with a number of popular AAC applications here.

nous™ is now available for purchase.

The nous™ package includes:

  • The wearable blink sensor.

  • The companion nous™ app that connects the sensor to your AAC software of choice, handles calibration etc.

  • Online support, should you need it.
