Well, there is a technology called FNIRS, which uses infrared light to detect blood flow in the brain kind of like fMRI, but without the giant expensive equipment. It's pretty new, and the signal is quite noisy. I'm skeptical of how good the quality of the interface could be when there is an unavoidable 2-4 second latency due to blood flow.

In the keynote it is asserted that the optical technology will not use blood flow but some other (more direct) measure of neural activity. It sounds to me like a near infrared form of intrinsic imaging. Very intriguing if it works.

Were there any details on what they use if not blood flow?
