Brainwave-Controlled Audio Visualisation
Using 30 channels of EEG data to control six Gaussians and their five independent parameters ( , , , and amplitude ), I created a visualisation for Jailhouse Rock, by strongly modulating the amplitude parameters of each Gaussian with a sin wave of the correct frequency. The EEG signals were lowpass-filtered to smooth and denoise them before being used.
Zombies - A Work in Progress
This project was started for a talk I gave at Leamington Spa's Cafe Scientifique on emergent systems. The simulation was an attempt to show complex emergent behaviour in a simple particle system. Humans follow two simple rules - they like to be close to other humans, but not too close, and they run away from zombies. Zombies only follow one rule - they move towards humans. When they interact, if the zombie's attack was successful, some calculations are done involving the human's health and the human either immediately turns into a zombie, or is contaminated, and will turn at a later point. The simulation in this video is still at a relatively early stage, and the interaction parameters are not properly calibrated, but visually, it's still very interesting.
This is the superposition of my structural MRI scan onto my photo. Tomohiro Ishizu, of UCL's Wellcome Lab of Neurobiology, was kind enough to allow me to leave with the data from my scan, after I participated in his experiment on the neural correlates in the perception of beauty.
Using the same EEG data as in the first video, I was able to recreate the introduction to Deep Purple's Smoke on the Water, as if it had been "played by the brain". The data was concatenated, smoothed at the boundaries, heavily resampled, bandpass-filtered at the correct frequencies and hacked at in other ways to produce this three-instrument piece. The video
