"Visual information display systems connected to computers are fast becoming commonplace. They are found now in stock brokers' offices and schools as well as in jetliner control panels. The National Aeronautics and Space Administration and its contractors have developed and operated display systems of this type that can span nearly the whole spectrum of applications. This survey of computer-related visual information display systems was undertaken for the NASA Office of Technology Utilization so that others may benefit from NASA's experience. The input-output capabilities of human beings, which determine the requirements for such systems, are likely to be much the same outside of the aerospace field as they are within it. This publication is intended especially for middle management personnel in areas in which the potential benefits from such modern technology have not yet been realized. The report describes hardware and software with wide applications and explains the large-scale checkout and control systems used at the John F. Kennedy Space Center, the Marshall Space Flight Center, and the Manned Spacecraft Center. It also reviews findings in the Ames Research Center, the Jet Propulsion Laboratory, and other government and private laboratories. The reader is introduced to interactive display systems, simulation displays, and image enhancement techniques. Most of the examples cited are from aerospace work, but they were chosen because of their potentially broad utility."--Foreword.
