Background:

  • Brain-computer interfaces (BCIs) offer novel communication and control pathways.
  • Electroencephalography (EEG) is a non-invasive method for capturing brain activity.
  • Recognizing subject-specific EEG patterns is crucial for effective BCI operation.

Purpose of the Study:

  • To develop a BCI system leveraging subject-specific EEG patterns.
  • To enable real-time control applications, such as cursor manipulation.
  • To evaluate different EEG feature extraction and classification techniques.

Main Methods:

  • Recording EEG signals from sensorimotor areas during imagined movements.
  • Implementing on-line classification of EEG patterns.
