Three-dimensional versus two-dimensional displays for air traffic control.
(pp. pp. 431-441).
© 1997 by Mark A. Brown.An empirical study was carried out comparing two-dimensional and three-dimensional displays for air traffic control, exploring.the suitability of 3D displays for ATC. Experiments compared the performance of two subject groups (air traffic controllers and novices with no ATC experience) using three types of display (2D, pseudo-3D and stereoscopic 3D) over a number of tasks: Observations of azimuth angle and distance between two aircraft; selecting two aircraft from a scene based on criteria of highest and lowest, and closest horizontally; and a conflict detection task. The results largely supported the findings of 3D display research, but behavioural differences were observed between the novices and controllers. Evidence was found that subjects tended to detect conflicts by examining horizontal and vertical separations separately rather than exploiting the integrated characteristics of the 3D displays. This may negate some of the benefits of a 3D visualisation, but whether controllers can be trained to exploit fully the integrated presentation of a 3D display remains to be investigation. Finally, controllers invited to view and comment on a virtual reality demonstration rejected immersive VR technology for radar control, but found it potentially useful for visual control room simulation and for workspace design.
