So, neurotechnology for games is definitely on the rise. Usability and interaction research in games and player experience as well, judging from the positive reception of the talk I gave on the Quo Vadis 2008 Entwicklerkonferenz in Berlin last week. Now, I finally found the time to upload the slides. Hope they are helpful to you. If you have any questions concerning biofeedback gaming, game usability research or interaction techniques, please do not hesitate to write an email!
