Four years ago DARPA launched a program aiming to dramatically improve soldiers’ awareness of their surroundings. CT2WS (Cognitive Technology Threat Warning System) is a portable visual threat detection device that integrates different technologies such as flat-field, wide-angle optics, large pixel-count digital imaging, cognitive visual processing algorithms, and on top of that an EEG brainwave scanner, namely a B-Alert headset.The CT2WS is capable not only of identifying up to 91 percent of targets during testing with extremely low false-alarm rates, but also widening a soldier’s field of view to 120 degrees when all components of the kit are is use.
The system consists of a 120-megapixel camera on a tripod, based on the battlefield, and a computer system, where a soldier sits in front of the computer monitor with an EEG strapped to his head. A cognitive visual processing algorithm identifies potential targets (enemy combatants, sniper nests, IEDs) and these possible threats are then shown to an operator soldier wearing an electroencephalogram (EEG) headset that monitors the operator’s brain signals and records when the operator detects a threat.
The components can be configured as necessary to work with existing systems and meet specific mission requirements.
In testing of the full CT2WS kit, absent radar, the sensor and cognitive algorithms returned 810 false alarms per hour. When a human wearing the EEG cap was introduced, the number of false alarms dropped to only 5 per hour, out of a total of 2,304 target events per hour, and a 91 percent successful target recognition rate.
