This paper is part of symposium entitled “Obtaining New Perspectives with Head Coupled Simulators.” The paper's purpose is to present and discuss the problems associated with assessing visual performance during translation and rotation in a virtual world. Two studies are summarized which highlight the difficulties in defining and measuring the optical and visual variables that pilots use during the control of a craft in simulated flight.
