The purpose of the proposed research is to demonstrate a software system that makes correctional/factor type analyses of large data bases practical on microcomputer-class machines, and is able to compute the significance of psychophysiological measurements at a speed that makes real-time feedback control mechanisms possible. The software prototype developed will access a data base composed of a wide range of measurements, analyze them to discover significant patterns of response, abstract "typical" patterns for a variety of physical states for each subject, and provide for the comparison of new measurements with the previously constructed set of "typical" patterns in order to provide input for the control of subsequent external events.

In the Phase I project, "the analysis of psychophysiological measurement to support biofeed-back control mechanisms", a software system was built and demonstrated which makes correctional/factor type analysis of large data bases practical on microcomputer-class machines, and is able to compute the significance of psychophysiological measurements at a speed that makes real time feedback control mechanisms possible. The success of this project strongly suggests a generalization of the software system into a generic multichannel data analysis capability with broad applications. The Phase II project will develop commercially useful implementations of the software demonstrated in Phase I and investigate the generalization in specific areas of interest to the air force and to non-federal funding sources who have expressed interest. These areas specifically include the application area of Phase I expanded to include cardiovascular disease risk modification programs, electrocardiovascular beat classification and reconnaissance and intelligence analysis.
