Abstract
New technology for submarine periscopes requires that all information be presented on a graphics workstation. The research presented in this paper is concerned with the design of periscope workstation displays for orientation information. In this experiment 24 people made judgments of orientation using three types of component displays (submarine, periscope, and relative) and two types of worldviews (north-up and track-up). Results revealed that the judgments of orientation were best with the north-up display, with relative questions the most difficult to make. When rotations were required for a response, characteristic mental rotation curves were found. The results are discussed in terms of factors affecting the design of displays for orientation information, selecting the best display format for the periscope workstation, and the processing strategies used to process orientation information.
