Continued Performance Assessment Methodology (PAM) Research (VORPET). Refinement and Implementation of the JWGD3 MILPERF-NAMRL Multidisciplinary Performance Test Battery (NMPTB).

Abstract

The Vestibulo-Ocular-Reflex Performance Evaluation Test (VORPET) developed at the Naval Aerospace Medical Research Laboratory gives a measure of left- an right-directed gale shift threshold time used to assess the type of head/eye coordination relevant to the aviator who routinely makes large shifts in gaze during his scan of cockpit instruments and the outside environment. Automation of the VORPET requires the use of a voice recognition system for the collection and scoring of the subject's voice response. We tested the accuracy of the VOTAN voice recognition system in collecting subject's voice response to that of the present method that uses a test administrator to listen and hand enter subject's responses when administering the VORPET. Thirty-six subjects were administered the-VORPET test under three different conditions (a) direct viewing of the stimulus digits presented on the CRT, involving no head movement VORPET administration using a test operator for subject's voice recognition and manual data entry, and (c) VORPET administration using the automatic voice recognition system for subjects voice acquisition and recognition. Four, three, and two digits were used as visual stimulus for each method used. The hypothesis to be tested was that there would not be a significant statistical difference in the results when methods (b) and (c) were used. Analysis of variance of test resultS indicate that there were significant differences between the thresholds obtained when method (b) and (c) were used to administer the VORPET. The VOTAN automated voice recognition system cannot be used to automate the VORPET. VORPET, Gaze Shift, Scan, VOTAN voice recognition, RA V, MIPR, Performance, Test.
