Effect of geometric parameters of perspective on judgements of spatial information.
15 university students performed an exocentric judgement task in which they estimated the azimuth and elevation separating two computer-generated cubes, using a perspective display. The perspective displays were created by varying two geometric parameters of perspective, the geometric field of view and station-point distance. Further, the radial distance separating the computer-generated images was varied. Analysis indicated that azimuth errors varied as a function of geometric field of view, radial distance, and station-point distance, while elevation errors varied as a function of geometric field of view and radial distance.
