Resolution and Performance Effects of Three-Dimensional Display Rotation on LocalGuidance and Spatial Awareness Measures

摘要

Computer technology has made it possible for the traditional paper map to bereplaced with a realistic, three dimensional, easily updated picture of the world. Possibilities abound as to exactly how this new computer map should be designed and implemented for use in aviation. what kinds of tasks should such a map support. Should the map depict the pilot's viewpoint or should the aircraft be viewed from a distance. If from a distance, how far and from what angle should the ownship be presented. In the present research we intend to give insight to the answers to some of these questions by investigating manipulations of two important properties of three dimensional displays (their elevation and azimuth angle), and assessing how these manipulations influence performance or interact across aviation relevant tasks. We will begin by describing three categories of navigational tasks. Next, we will describe a general model of three dimensional space and the biases created by perspective viewing, and will continue with a review of the research that has addressed these subjects.
