Out-of-the-window visual simulation is a formidable challenge because of the fantastic performance capabilities of the human eye, the impracticability of producing a simulation system matching this performance and the inadequate understanding of how a human uses the visual information in a simulator. There is a continuing task to define the design characteristics that may affect perception of physiological responses, to establish the relative importance of the corresponding visual and physiological effects, and to understand their relationships with the physical continuums of the displays that can now be generated. This report addresses only a very small part of the total problem, by identifying and defining those physical parameters that characterise the simulator visual system and determine its fidelity. These characteristics are discussed in terms of the three basic categories of spatial, energy and temporal properties, and for each of the parameters there is a description of its effect, a definition of its appropriate units or descriptors, a discussion of methods of measurement and of its use or importance to image quality. There is also a presentation of the experience of the Working Group members regarding the importance of these parameters in accomplishing a given visual task under given conditions. The final chapters of this report present projections of future trends and recommendations for research.
