I’ve recently created a small hack which combines the output of my Neurosky Mindwave EEG with the Philips Hue system which allows me to change the colors of our living room lights with my mind. Currently the lights change depending on my concentration levels. This is just the tip of the iceberg for this brain to computer (BCI) interface since we can use all kinds of different readings, not just attention levels, to change the colors and brightness levels of the lights. Of course this relates to a bigger project that I’ve been working on, Cognichrome, which will allow someone to paint a real painting with their mind. A three minute demonstration video here:
Update: Changing colors through meditation.
