  2. 1. Classifying of EEG Signals Recorded During Right and Left-hand Finger Movements

    University essay from Chalmers tekniska högskola/Institutionen för signaler och system

    Author : Sima Shahsavari; Hector Montes; [2006]
    Keywords : Brain Computer Interface BCI ; Event Related Potential ERP ; Event Related Synchronization Desynchronization ERS ERD ; spatial patterns; CSP; CSSD; single trial classification; electroencephalogram EEG ; finger movement; linear Fisher’s; discriminant; kernel Fisher discriminant; Gaussian mixture models; support vector machine; Quadratic Bayesian discriminant; Mahalanobis distance classifier;

    Abstract : Brain Computer Interface (BCI) technology allows a person to control a device by bypassing the use of muscular activity. Signal processing and classification methods play a decisive role in the performance accuracy in BCI application. In this thesis extensive comparison among novel electroencephalic(EEG) pattern recognition methods is provided. READ MORE

  4. 2. A Real-Time Classification approach of a Human Brain-Computer Interface based on Movement Related Electroencephalogram

    University essay from Linköpings universitet/Institutionen för konstruktions- och produktionsteknik

    Author : Martin D. Mileros; [2004]
    Keywords : Technology; Real-Time Brain-Computer Interface RT-BCI ; Blind Signal Separation BSS ; Canonical Correlation Analysis CCA ; Electroencephalogram EEG ; Artificial Neural Networks ANN ; Real-Time Classification RTC ; Ten-Twenty Electrode Application System 10-20 System ; TEKNIKVETENSKAP;

    Abstract : A Real-Time Brain-Computer Interface is a technical system classifying increased or decreased brain activity in Real-Time between different body movements, actions performed by a person. Focus in this thesis will be on testing algorithms and settings, finding the initial time interval and how increased activity in the brain can be distinguished and satisfyingly classified. READ MORE

  5. 3. A Neural Network Based Brain-Computer Interface for Classification of Movement Related EEG

    University essay from Linköpings universitet/Institutionen för konstruktions- och produktionsteknik

    Author : Pontus Forslund; [2003]
    Keywords : Brain-Computer Interface; Neural Networks; EEG; Autoregressive modeling;

    Abstract : A brain-computer interface, BCI, is a technical system that allows a person to control the external world without relying on muscle activity. This thesis presents an EEG based BCI designed for automatic classification of two dimensional hand movements. READ MORE
