A P300 Brain Computer Interface Keyboard to Control Assistive Technology For Use by People With Amyotrophic Lateral Sclerosis

A P300 Brain Computer Interface Keyboard to Control Assistive Technology for People With Amyotrophic Lateral Sclerosis

People with Amyotrophic Lateral Sclerosis (ALS) will use a P300 based brain computer interface (BCI) keyboard to type in assistive technology devices. The results of this study will be compared with a previous study of a P300 BCI keyboard used by healthy volunteers.

Inclusion Criteria:

• Age 18 or older.
• Diagnosed with cerebral palsy, spinal cord injury, neuromuscular disease, or ALS that results in impaired hand and arm function making it difficult to manipulate objects (if at all) and requires help to prepare or modify activities
• Able to see the BCI display
• Able to give informed consent
• Able to understand and remember instructions concerning participation
• Able to communicate effectively at least with familiar conversation partners

Exclusion Criteria:

• Are unable to give informed consent.
• Are currently experiencing open head sores
• Have a history of photo-sensitive epilepsy
• Have a history of cognitive deficits requiring accommodation or special education services
• Are unable to sit without moving the head and neck for at least 15 minutes
