The Grail for Brain-Computer Interfaces (BCI)–or at least an interim grail–is being able to think words into a computer. Through what seems to be a fairly painstaking process, this can now be accomplished.
It’s an exciting proposition, I think, because it suggests the idea of typing at the speed of thought. Of course, it turns out that we have a really nicely designed thoroughfare to the brain in our hands, and it shouldn’t be surprising that bypassing the hands to go through the skull makes things more, rather than less, complicated. I don’t expect that we will be bypassing physical manipulation any time soon, but I can dream of a day when my clumsy hands don’t get in the way of a quick blog entry.
