Pretty interesting. The speed with which science and technology are advancing... who knows where it will lead. From what I understood from the info, the key problem is that they have to calibrate the reading device for each individual person. So they show Bill an X and based on the specific brain readings for Bill, they arrange the large pixels on the "reading" screen to make an X. Latter when they have Bill think of an X, the "reading" screen shows a close version of the X. The challenge with all of this is that the various neural pathways not only vary among individual brains but also change over time (Neuroplasticity). The brain amazes me. I would love to someday see my dreams on a screen. Of course, by the time it happens, you wouldn't be watching a screen, but instead holographic 3D images in the middle of a room.

Thanks for posting the links.
