Veritas Scientific is working on an EEG helmet that carries a slideshow of images that could, they hope, reliably identify an enemy. The device is shaped like a motorcycle-helmet with metal brush sensors that will read brain activity as images flash quickly across the inside of the visor. Electroencephalography (EEG) is the science of measuring brainwave patterns produced by the brain in response to internal or external stimuli. Familiar images prompt spikes of electrical brain activity that indicate recognition, say scientists.
