How to Make a Visually Realistic 3D Display Margaret A. Hagel~, Ph.D. Deparmwm of Psychology Boston University 64 Cummington Street Boston,, Massachusetts 02215 (617) 522-0705 What is a three-dimensional display? A 3D display is basically a picture - a complex picture, a picture of a whole world you want the user to be able to enter. That world nmst carry in fommtion that is easy to understand about the state of the system and the possible actions and present options open to the user. A display that is well-designed does not require long periods of training to master. A well-designed display takes advantage of the perception and action knowledge base the user already has flom acting and interacting in the ordinary world. To make it possible for the user to enter and interact with the 3D world of the display, the display designer must follow the well established rules of creating visually realistic 3D pictures. Most of the rules for creating realistic pictures are just a subset of the rules for describing visual perception of the ordinary 3D world. As we shall see below, this subset must be coupled with the rules governing pelception of projections on a
