An evaluation of perceived urgency applied to amplitude modulated stimulus for military applications
by Moore, Tyrone D., M.S., IOWA STATE UNIVERSITY, 2011, 184 pages; 1494705

Abstract:

Virtual and augmented reality is being developed for applications such as training, engineering design visualization, and controlling Unmanned Aerial Vehicles (UAV's) in combat zones. These environments contain complex sets of visual information and at the same time provide the opportunity to create virtual environments that overload the cognitive ability of a human user. To reduce the cognitive load of the visual channel, audio can be introduced utilizing a dual-channel processing with auditory and visual information. Being able to augment the virtual environment with audio signals can provide a higher quality response to visual information and increase overall user performance. The proposed research will investigate the potential for using the psychoacoustic qualities of a background sound to continuously monitor the health of a system and trigger a task in the virtual environment.
