Analyses of aviation accidents ascribe about 75% of all incidents to human (Pilot) behaviour. A strong effort is being made to improve ergonomic cockpit layout, because of dramatic changes in the airspace structure, the increase in air traffic, and larger aircraft. One part of an interdisciplinary research project investigates the potential of stereoscopic flight-guidance displays in order to improve pilots ' situation awareness.This experimental approach, which aims to research and apply ergonomic design recommendations for stereoscopic flight displays, is based upon a new type of perspective flight-guidance display. The examination of existing research regarding stereoscopic flight displays reveals a lack of basic knowledge, as well as a need for further systematic research into cockpit application.Thus the project contains experiments on different levels of abstraction, ranging from classic parameter experiments to flight simulator tests. Both current knowledge and recent discoveries are applied to superimposed 2-D fi ight parameters and to real and synthetic 8-D elements, such as a perspective landscape, other airplanes or flight prediction. The stereoscopic layout takes into consideration specific informational needs within different flight phases and is evaluated by means of pilot performance and pilot strain. Selected symbols of the flight guidance display and actual results are presented as examples of the research approach.
As part of an interdisciplinary research project, sponsored by the German Research Community (DFG), the Darmstadt University of Technology investigates the potential offered by stereoscopic flight guidance displays for improving pilot situation awareness. The research aims to formulate ergonomic design recommendations for this type of display.Recent developments in display technology offer new opportunities to improve human-machine interfaces in the cockpit. The utilization of three-dimensional display symbology, as a depiction of three-dimensional sensor or database information, has become an accepted practice in modern enhanced and synthetic vision systems. Nevertheless, the information is depicted on a conventional two-dimensional screen. This can cause problems and errors during the cognitive process of depth perception. The application of stereoscopic technology can add an additional cue which is intuitively seized by the observer.The project concentrates on stereoscopic perspective flight guidance displays as a head down display. The extension to other display types like navigation or head-up display is possible. Because of the complexity of a modern synthetic vision display, the project contains experiments on different levels of abstraction, ranging from classic parameter experiments to flight simulator tests. The stereoscopic layout takes into consideration specific informational needs within different flight phases and is evaluated by means of pilot performance and pilot strain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
