Abstract
Historically, map projection problems have been 2-dimensional. With air and space travel however, the need for accurate 3-dimensional projections has come about. This paper describes an experimental comparison of a fixed 2D projection and a user-defined 3D display for the depiction of satellite altitude and coverage area. Sixteen subjects completed 24 trials, 12 with each display orientation, which required them to make a True/False decision concerning a statement describing the altitude and coverage area of a particular satellite on the display. Reaction time (RT) and errors were collected and analyzed via separate ANOVAs.
The results of the study revealed that subjects preferred a “3D-looking” display, even though there was no significant difference between display orientations with respect to RT or errors. From research of this type we hope to produce user-oriented guidelines for future space situation displays.
