Development of Oculometrics for Operational Based Vision Assessment.

摘要

This project is part of a larger program conducted at the USAF School of Aerospace Medicine's (USAFSAM) Operational Based Vision Assessment (OBVA) laboratory to determine whether an individual's motion sensitivity is predictive of their operational performance. The Air Force does not currently have a standard method to measure an individual's motion sensitivity and a first step was to research the feasibility of using such an approach. Previous research with the University of Birmingham used perceptual tests to estimate the distribution of motion thresholds, found a significant range of thresholds in the normally-sighted population and demonstrated that scores on these tests are predictive of driving performance. In the effort described here, USAFSAM defined project objectives and funded NASA's Ames Research Center (ARC) to investigate an alternative method that uses eye movement measurements (oculometrics), which were developed at ARC, to estimate an individual's motion sensing capability. This final report describes their work. NASA-ARC conducted experiments in their laboratory and delivered oculometric data for a normally-sighted cohort of 40 subjects.
