From Touchpad To Thought-pad

An anonymous reader wrote with a story saying "Move over, touchpad screens: New research funded in part by the National Institutes of Health shows that it is possible to manipulate complex visual images on a computer screen using only the mind. The study, published in Nature, found that when research subjects had their brains connected to a computer displaying two merged images, they could force the computer to display one of the images and discard the other. The signals transmitted from each subject's brain to the computer were derived from just a handful of brain cells."

Handful of Brain Cells

That's quite an ambiguous term. For instance, my hand can probably hold about 1/3 of my brain matter.

However, my girlfriend hand (which is considerably smaller than mine) could probably hold several brains the size of her own.

Now this joke is really getting out of hand...

brain interface pfft!

My computer has been controlled by my brain for years. I think about how i want my fingers to move and the text gets entered into the system. As an added benefit, i can prevent my computer from accepting text from my thoughts by simply putting my hands in a different place!

The problem with tougth...

.. is that you cant avoid thinking. In voice controlled interfaces exist the problem of what happens when you talk with someone, but with tougth, is just worse. Imagine that the computer detect the pattern needed for some action when you watch porn, or read a particular word or phrase (that could get a new via for malware)
