This project specifies requirements for testing platforms and facilities that will enable the use of neurophysiological data to help improve human computer-interfaces. The data used to generate these requirements was collected as part of an advanced human factors effort aimed at improving the usability of future releases of the Tactical Tomahawk Weapons Control System (TTWCS). Cognitive state was measured using electrocardiography (EKG), galvanic skin response (GSR), and electroencephalography (EEG), in addition to traditional measures using various subjective and psychological analyses. This project demonstrated the value of neurophysiological measures into the Human Computer Interaction (HCI) design process, including increased objectivity of measures and consistency between measures. Simultaneous neurophysiological and psychological measurements will enable researchers to better understand true usability of an interface and the requirements documented herein will enable such research.
