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
