Background The human perceptual system carries information from the operator's environment to his cognitive and action systems. Although the perceptual system gives us the illusion of being in direct contact with "the real world," it is a complex system that uses heuristics to construct a world representation from sensory data that can be sparse and unreliable without any such notification to the user. Understanding the perceptual system is necessary to predict the performance of a human operator and improve display interfaces. Objectives The goal of this program is to provide the aviation community with research and technology in perceptual systems that allows scientific assessment of perceptual system capabilities and fosters improved aviation display technology. Approach Develop improved methods for measuring perceptual system performance. 2) Collect experimental data on perceptual system performance. 3) Develop computational models and metrics that predict perceptual system performance. 4) Develop display technologies that exploit understanding of perceptual systems.
