Valence(Tom De Smedt, Lieven Menschaert and Ludivine Lechat, 2011) is an interactive installation that represents the player's affect (relaxation or arousal) by measuring alpha brain waves, using a wireless EEG headset. The headset prototype is developed by Imec (BE) and Holst Centre (NL). It consists of eight dry electrodes and a wireless broadcaster.Using NodeBox for OpenGL, we developed a game environment that interprets the alpha and valence state of your brain. In a follow-up project we've expanded our setup with ambient lighting. We used a home automation server to control the lighting's intensity based on the player's affect.
