Abstract
THE ACCELERATING TEMPO OF MILITARY OPERATIONS INCREASES THE TASK DEMANDS AND WORK RELATED STRESSES IMPOSED ON HUMAN OPERATORS. AS NEW TECHNOLOGICAL DESIGNS ARE INCORPORATED INTO MILITARY SYSTEMS, A METRIC IS REQUIRED TO ENSURE THAT HUMAN COGNITIVE WORKLOAD LIMITS ARE NOT EXCEEDED. SOME PROGRESS IN THIS ENDEAVOR HAS BEEN ACHIEVED IN USING AS OBJECTIVE WORKLOAD INDICATORS A VARIETY OF ELECTROPHYSIOLOGICAL TECHNIQUES, INCLUDING EEG AND NEURAL EVOKED POTENTIALS. HOWEVER, THESE OBJECTIVE TECHNIQUES TEND TO BE INTRUSIVE, RELATIVELY ARTIFICIAL, AND NON-PORTABLE. WE BELIEVE THERE ARE MORE READILY OBTAINABLE MEASURES THAT CAN SERVE AS IMPLE EXTERNAL INDICANTS OF WORKLOAD, AND WHICH CAN BE BUNDLED IN PORTABLE, VEST-POCKET SYSTEMS TO BE EMPLOYED IN APPLIED WORKLOAD ASSESSMENT. WE HAVE HAD SUCCESS IN LABORATORY RESEARCH RELATING EYE MOVEMENT CHARACTERISTICS (VELOCITY, ACCELERATION, ETC.) TO A TASK SCALED IN COGNITIVE WORKLOAD. IN PHASE I, WE PROPOSE TO DERIVE A TRANSFER FUNCTION BETWEEN THESE EYE MOVEMENT INDICANTS AND TASK DEMANDS BY USING A SET OF TASKS WHICH ARE INDEXED FOR LEVEL OF COGNITIVE WORKLOAD. FROM THESE RELATIONS, A PROTOTYPE OF A TRANSPORTABLE DEVICE IN WHICH EYE MOVEMENT DATA ARE COLLECTED AND AUTOMATICALLY SCORED WILL BE DEVELOPED FOR FIELD USAGE.
