Valence (Tom De Smedt, Lieven Menschaert & Ludivine Lechat, 2010) is an interactive installation developed in NodeBox for OpenGL (http://www.cityinabottle.org/nodebox) 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).
