The electrical activity of the brain in response to a visual scene is being used as an adjunct to measurement techniques in several human engineering and medical applications. Recorded from electrodes placed on the subjects scalp, this evoked potential sensitively measures the way that the human responds to differing presentations of the outside world. It permits evaluation of the effects of changes in the sensory qualities of a displayed scene, as well as the cognitive demands and response requirements of a specific task. As such, the evoked potential provides a unified metric that allows the engineering psychologist to assess the total requirements placed on the subject, from sensory input to motor output. Several studies are reported using this technique to answer questions of display design and operator performance.
