Abstract
Researchers explain a model of navigation that proposes that local guidance and global awareness are better supported by more, and less, egocentric displays, respectively. Greater egocentrism is created by perspective viewing, map rotation, and viewpoint positions that correspond to the axis of control. The model was tested in an experiment in which 40 pilots flew simulated landings with displays that varied the degree of egocentrism between a fully egocentric viewpoint, 3 distances of exocentric 3-dimensional viewpoints, and a 2-dimensional planar display. The results generally supported model predictions: The egocentric viewpoint supported best guidance, whereas the mid-distance exocentric viewpoint supported best global awareness. Implications of the model for the design of flight displays in particular, and navigational displays in general, are discussed.
