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.
