The value of spatial cues in 3D air traffic displays
2007 (English)In: The International journal of aviation psychology, ISSN 1050-8414, E-ISSN 1532-7108, Vol. 17, no 2, 109-129 p.Article in journal (Refereed) Published
Abstract [en]

Interest in implementing 3D pictorial displays for traffic information in aircraft has been prevalent for decades without any obvious implementation in the cockpit. Our research is focused on design issues for these displays. The purpose of the experiments discussed here was to investigate where and when additional spatial cues, e.g., drop-lines, could contribute to better performance and whether such additions could replace shifts between 2D and 3D presentation for different tasks. Our results show that drop-lines are beneficial in focused attention tasks but are not necessarily beneficial in more integrated tasks. This speaks to the need for an adaptive approach to the presentation of flight situation displays.

Abstract [en]

The purpose of this thesis is to evaluate the possibilities of using 3D perspective displays in different military settings, and to illustrate the limitations of 3D displays, that is, when 2D displays are to be preferred. More specifically, this thesis explores (a) readability during vibrations, (b) perception aspects on perspective aircraft displays, and (c) the value of spatial cues in 3D air traffic displays in military settings.

The results show, for example, that vertical vibrations influence recognition performance negatively. The recognition of 2D and 3D symbols, as well as judgment of relations between symbols on a 3D display, may indeed be an arduous task. Results, further, indicate improved performance for relation judgments between objects in 3D space in dynamic rather than static scenarios in tactical indicators. In situations where perception of a direction nevertheless is problematic, enhancements like, for example, drop-lines may improve performance.

From a practical point of view the goal has been to investigate the possibility to develop and use a 3D perspective display in an airplane like JAS 39 Gripen. A general conclusion is that 3D displays indeed can be used in many situations but it is important to seriously consider any possible limitations of 3D displays. The future work should be focused on implementing and testing the tactical display in a real setting with real military pilots.
