Creativity is needed in the area of brain–computer interface (BCI). So far the interfaces seem too crude and pre-historic. Both invasive and noninvasive methods seem like dinosaurs. The noninvasive approach of electroencephalography using probes on the skin of the brain is still too far away from the neural action.  The invasive approach is having to decide where in the brain to connect to. There is a great overview on Wikipedia. These are just my thoughts today.
