Measurement of useful field of view in eye and head-free condition while driving

Abstract

In this study, we conducted an experiment aimed at developing an effective method for measuring the useful field of view when driving while maintaining free visual (eye and head free) conditions with completely unobstructed head and eye movements. In the experiment, the mental workload was changed in a stepwise manner in order to test the hypothesis that the useful field of view becomes narrower as the mental workload (MWL) increases, as well as to verify the accuracy of the proposed method. The results confirmed the validity and accuracy of the proposed method for measuring the useful field of view under completely unobstructed visual conditions. © 2013 The Japan Society of Mechanical Engineers.
