The eye passes on more information to the brain than the brain will process. In that sense, the brain functions as a filter. But on the battlefield the risk of neglecting information could mean the difference between life and death. To take away the filter is the idea behind a pentagon-funded project to develop “brainwave binoculars”.
Intelligent binoculars can tap into the brain’s ability to spot patterns and movement to help soldiers detect threats from miles farther away than they can with traditional binoculars. Electrodes on the scalp inside a helmet will record the user’s brain activity as it processes information about high-resolution images produced by wide-angle military binoculars. Those responses will train the binoculars over time to recognize threats.
