Mind meld: DARPA tested its human-in-the-loop sentry system in a simulated setting.

Sentry System Combines a Human Brain with Computer Vision

A DARPA project suggests a mix of man and machine may be the most efficient way to spot danger.

Sentry duty is a tough assignment. Most of the time there’s nothing to see, and when a threat does pop up, it can be hard to spot. In some military studies, humans are shown to detect only 47 percent of visible dangers.

A project run by the Defense Advanced Research Projects Agency (DARPA) suggests that combining the abilities of human sentries with those of machine-vision systems could be a better way to identify danger. It also uses electroencephalography to identify spikes in brain activity that can correspond to subconscious recognition of an object.

An experimental system developed by DARPA sandwiches a human observer between layers of computer vision and has been shown to outperform either machines or humans used in isolation.
