But if the person is a quadriplegic controlling the cursor with nothing but brainwaves, now that would be interesting. And it's been done.

Brain-computer interface systems, although still in developmental and experimental stages, are becoming increasingly more powerful and applicable. Advancements in neural signaling research make it one of the hottest fields in biomedical engineering...
