I had to explain some scientific journals in my laboratory seminar yesterday, so I took a paper about neurally controlled robotic arm. People with posteriori tetraplegia is implanted electrodes in the brain and, using the firing data from this electrodes, the authors estimated the robotic arm's movement by Kalman filter. Kalman filter is used in car navigation system to estimate the position of a driving car from GPS information. In this paper, the tetraplegia patient can brought a bottle of coffee and drank it for the first time after her impairment.
I can't forget her joyful face after the task.

I wonder whether I will have enough bravery when we can control many devices freely using implanted electrodes in brain.
