Mindprocessing by Sam for MAC/VAL Image:Mindprocessing.jpg
The idea is to map brain activity (imagine a scale of concentration) to a music scale and a color scale. Mindprocessing was about making these highly intimate datas accessible to everyone in the room in a... positive way.

The High gamma wave value was transformed in color hue and drive 5 LED projectors using a classic HSL to RGB algorithm. 5 projectors to memorize and display the last 5 second "colored" brain activity. (1) The High gamma value was also to switch octave on a previously written music handled in Puredata.

A video is coming soon. The used software is available on /tmp/bci repository
