Beat Circles

Beat Circles represents music graphically, in a aesthetically pleasing and informative way, without any loading times. It allows users that are not proficient with music to better understand and interact with the piece using intuitive creative thought.
 

The Hardware

The NeuroSky MindWave Mobile is an inexpensive research-grade EEG headset. The MindWave measures and outputs the EEG power spectrums (alpha waves, beta waves, etc.), the NeuroSky eSense meters (attention and meditation) and eye blinks.

The Software

These visualizations are built using Processing, a programming language used specifically for the visual arts. Most of the illustration modes are based on sampling and frequency analysis, assigning different shades of colour depending on the pitch, and different behaviours and sizes according to the frequency amplitudes.

Various modes of information representation are available, each highlighting different aspects of the sources.
