For my university thesis research I worked on mapping brain waive activities to emotional states and behavior. The goal was to utilize that as a control interface for performances.
The EEG headset I used was a Neurosky MindWave, to overcome the device’s slow refresh rate and latency I re implemented a communication library that would analyze and re calculate the brainwave bands at faster rate. Those brainwave bands as well as the raw data was then recorded and key stoned with different emotional states. After that an artificial neural network was trained with the recorded data sets to recognize those emotional states on real time incoming data.
During the early stage of experiments I also mapped the neural network output and brainwave bands to the MIDI protocol, enabling interaction over audio and visual material, that would then feedback and change the emotional state of the user.
