Abstract Brain-Computer Interfaces (BCIs) are systems allowing people to interact with the environment bypassing natural neuromuscular and hormonal outputs of peripheral nervous system (PNS). These interfaces record a user’s brain activity translate it into control commands for external devices, thus providing PNS additional artificial outputs. In this framework, BCIs based on P300 Event-Relate...

The ability to communicate by speech, text or gestures is essential to human interaction. This ability is impaired in many people who are affected by debilitating neuromuscular disorders such as amyotrophic lateral sclerosis (ALS), brainstem stroke, or spinal cord injury. Conventional assistive devices (e.g., letter boards, cheek or tongue switches, or eye trackers) that aim to restore communic...
