The U.S. Army Aeromedical Research Laboratory Virtual Reality Vection System
Abstract
This presentation describes and documents the USAARL Virtual Reality Vection System (VRVS), a versatile, inexpensive, tool to investigate and characterize vection as a form of spatial disorientation (SD). In aviation, SD refers to the potentially catastrophic situation in which a pilot fails to correctly understand the position, motion, direction, or attitude of the aircraft with respect to the Earth's surface. Vection is a form of SD that generates the feeling of movement in an individual who is not moving. Since vection can be reliably generated under controlled laboratory conditions, it is a convenient model of SD. The VRVS is described, including its components, software, hardware and user interfaces. Tests and evaluations conducted while creating the VRVS demonstrate that the system reliably provokes vection-based SD. The VRVS includes two complementary methods for quantifying the presence and magnitude of the vection illusion. The VRVS enables the simultaneous measurement of vection as well as symptoms of cybersickness.Poster presented at the Military Health System Research Symposium, 14-17 August, 2023 in Kissimmee, FL.
