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... pleasant and positive way.

The mindset headset was used for it's auto adaptive capabilities to detect mental state changes. One of eight detected brainwaves, "hIgh gamma" are experimentally related to higher mental state, like concentration, and require little training. To minimize artifacts people experimenting the installation were asked to move as less as possible.

The detected high gamma wave value was transformed in color hue and drove 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

To learn more about Brain Computer Interface project /tmp/bci aka : Neurohack
(1) DMX connectivity for Enttec USB Pro interface used a London Hackerspace program : Lighted. Pascale Gustin provided the tcp link in PureData.
