Visual Information Display Systems

Visual Information Display Systems; a Survey

"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.

Visual Psychophysics

A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science.
