Darpa combines human brains and 120MP cameras for threat detection

It's interesting that the threat signal can be subconscious, ie you notice a threat but the signal isn't strong enough to cross over your conscious threshold. But if the computer notices the same thing it will act. Pretty kurzweilian in that they're augmenting our (pretty good) brain neural networks rather than replacing them, with the result being an order of magnitude better than either alone

Incredibly cool idea. Though I wonder if they couldn't use a well trained animal instead of a human as the 'threat detector'. This would allow more direct access to the brain (implanting electrodes in soldiers is not usually acceptable). It would also allow use of multiple animals to lower error rate.

However, a quick literature search indicates that there is not something as easy to monitor as P300 in animals so perhaps this is not feasible.

Very cool, but a crucial piece of information is missing, which is the false negative rate.
