Empowering ALS and locked-in patients to interact and communicate through brain signals

Problem  Many ALS or Locked-in patients are unable to interact with their surroundings or communicate as they have lost the ability to control voluntary muscles including facial and vocal muscles. Being locked-in means a patient is quadriplegic, and completely unable to move but mentally 100% alert. The prognosis for these patients is poor and quality of life low as they are unable to function independently and can’t communicate. Locked-in can be caused by ALS, trauma, brainstem stroke or acute muscle disorders, but is often difficult to diagnose.

Applications The BCI technology is easy to integrate with other technologies making it suitable for a range of applications.

  • Communication through spelling
  • Emergency alarm function
  • Interaction with Internet of Things

Solution MindAffect has developed a brain computer interface (BCI) that allows ALS or locked-in patients to interact or communicate by controlling a computer with brain signals. Patients wear an EEG cap that measures electrical brain activity. Through directing their attention at specifically designed stimulus, such as a special keyboard, the BCI matches the brain signals with the stimulus and thus allows a patient to spell per letter. This method is fast, reliable and requires no training.

Advantage For patients who dislike or are unable to use Eye-tracking, MindAffect’s technology provides a way to interact with surroundings.

  • No training necessary
  • Can be used with fashionable headset
  • Reliable (95% accuracy)
  • Can be integrated with different applications
  • Robust; can adapt to movement
