Brain Control Club progress meeting Project: EEGgames

  1. 1. Capture the alpha wave Capture motor movements Next steps Eeggames Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling March 6, 2017 Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  2. 2. Capture the alpha wave Capture motor movements Next steps Goal : Playing video games with eeg Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  3. 3. Capture the alpha wave Capture motor movements Next steps Capture eeg signals To make this work, we need to isolate some eeg signals Capture the alpha wave (Henri and Charles) Capture motor movements (Alexandre, Marc and Charles) Set up eeg (Heloise and Charles) Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  4. 4. Capture the alpha wave Capture motor movements Next steps Section 1 Capture the alpha wave Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  5. 5. Capture the alpha wave Capture motor movements Next steps Capture the alpha wave Goal : Online tracking of the alpha Detection of the individual alpha frequency Three approaches to obtain the alpha wave, implement the three, keep the best Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  6. 6. Capture the alpha wave Capture motor movements Next steps Three approaches Fourier transform F(f ) : z −→ +∞ −∞ f (x)e−izx dx Fitting a sinus minB||Y − XB|| Gabor filters f : z −→ exp (2πjf0z) × exp − (x − x0)2 σ2 Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  7. 7. Capture the alpha wave Capture motor movements Next steps Section 2 Capture motor movements Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  8. 8. Capture the alpha wave Capture motor movements Next steps Capture motor movements We wish to isolate: Right-hand movements Left-hand movements Feet movements Maybe expand to movements intentions Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  9. 9. Capture the alpha wave Capture motor movements Next steps Isolating online: Approach combining cnn and rnn Individual learning is possible. Implementation is done under python-tensorflow-keras Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  10. 10. Capture the alpha wave Capture motor movements Next steps Convolutional layer The convolutional layer is a morlet layer: Φσ(t) = cσπ−1/4 e−1 2 t2 (eiσt − κσ) Figure: Real valued morlet Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  11. 11. Capture the alpha wave Capture motor movements Next steps Section 3 Next steps Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  12. 12. Capture the alpha wave Capture motor movements Next steps Next steps Finish to implement algorithm Test it Work to make it perform better Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  13. 13. Capture the alpha wave Capture motor movements Next steps Problems Setting up the eeg 16 channels Computational power Data Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
  14. 14. Capture the alpha wave Capture motor movements Next steps Na tota Alexandre Kempf, Henri Vandendriessche, Marc Moreaux, Heloise Thero and Charles Findling Eeggames
