This study presents a P300-based brain-computer interface (BCI) system for aiding individuals with physical disabilities. The developed BCI system demonstrates high accuracy and reliability for communication and control applications.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Human-Computer Interaction

Background:

  • Brain-computer interfaces (BCIs) offer potential solutions for individuals with severe motor impairments.
  • P300-based BCIs utilize event-related potentials elicited by target stimuli for control.

Purpose of the Study:

  • To design and implement a P300-based BCI system.
  • To develop practical applications assisting physically disabled individuals.
  • To optimize BCI performance for accuracy and reliability.

Main Methods:

  • Design of a novel P300-based BCI system architecture.
  • Implementation of two distinct applications: a word speller and a remote control device.
  • Utilization of specific techniques to enhance system accuracy and reliability.
