BCI-Based Cursor Control Using EEG Sensorimotor Rhythms

Thesis by Sebastian Böhm

Supervision by Horst Eidenberger

Abstract

Brain-computer interfaces (BCIs) are human-computer interaction systems in which users communicate with a computer via a direct neural interface. Brain-computer interfaces have historically been closely associated with assistive technology for persons with disabilities, but the past few years have seen an increase in publications on human-computer interfaces for people without disabilities. The goal of a cursor control BCI is to control the position of a cursor via brain signals. While there have been a number of publications on cursor control using BCIs, most of them focus on controlling a cursor in custom-built experimental applications. The present thesis describes the design and implementation of a cursor control BCI prototype that translates EEG sensorimotor input into one-dimensional cursor movement and can be accessed using standard input interfaces. Since the BCI is accessible via standard input interfaces, existing input libraries can be used to create experimental applications and the BCI can be used to control existing applications.
