Computational Modeling of Foveal Target Detection. (Special Section)
INTRODUCTION Need and Scope Visual detection by human observers to is considered to be the major operational threat to individual vehicle and unit operation security. The U.S. Army, as well as the NATO countries, have recognized the need for...
Computational Motor Control and Human Factors: Modeling Movements in Real and Possible Environments. (Special Section)
INTRODUCTION Imagine the great advances the field of human factors could make if there were a perfect computer simulation of all human behavior. With this extraordinary tool, industrial engineers could design a multitude of efficient and comfortable...
Control and Perception of Balance at Elevated and Sloped Surfaces
INTRODUCTION Falls from roofs account for about one third of all fatal fall incidents in the construction industry each year (Bureau of Labor Statistics [BLS], 1999). In addition, injury statistics indicated that 3843 serious injuries (involving...
Effects of Head-Slaved Navigation and the Use of Teleports on Spatial Orientation in Virtual Environments
INTRODUCTION Virtual environments (VEs) are three-dimensional computer-generated images that can be presented in various ways: for example, on a conventional desktop monitor, on a large projection screen surrounding the operator, or on a head-mounted...
Empirical Assessment of Expertise. (Special Section)
INTRODUCTION All people depend on experts to make life safe (e.g., by providing basic resources) and interesting (e.g., by entertaining with music and art). Most people would claim to be experts, at least at something. But are they really expert?...
Mathematical Modeling of Decision Making: A Soft and Fuzzy Approach to Capturing Hard Decisions. (Special Section)
INTRODUCTION The role of human judgment and the factors associated with the "fallibility" of decision making have been central facets in many areas of human performance research (Guion, 1998, p. xi). Attempts to understand decision making have generated...
Modeling the Effect of Task and Graphical Representation on Response Latency in a Graph Reading Task. (Special Section)
INTRODUCTION The ability to interpret and reason with charts and graphs is increasingly important in this information-rich society. Charts, graphs, and other diagrams are used extensively in science, engineering, business, and the media. To be able...
Production Compilation: A Simple Mechanism to Model Complex Skill Acquisition. (Special Section)
INTRODUCTION In such diverse environments as air traffic control and nuclear power plant operation, researchers in human factors have accumulated extensive empirical knowledge of human performance in complex and dynamic tasks. However, the development...
Returning Human Factors to an Engineering Discipline: Expanding the Science Base through a New Generation of Quantitative Methods -- Preface to the Special Section. (Special Section)
ENGINEERING IN HUMAN FACTORS Human factors is a disparate discipline. Academic programs in human factors are found in departments of industrial engineering, psychology, mechanical engineering, architecture, optometry, and elsewhere. Human factors...
Steps toward Building Mathematical and Computer Models from Cognitive Task Analyses. (Special Section)
INTRODUCTION To understand the role of a human in a task, one frequently performs thorough task analyses. In contrast, mathematical and computer models are constructed infrequently and incompletely, perhaps because the perceived benefit of a model...
Time Estimation during Prolonged Sleep Deprivation and Its Relation to Activation Measures
INTRODUCTION Disturbances in the sleep-wake rhythm and sleep deprivation are frequent events. Many people - for instance, night-shift workers, truck drivers, airplane pilots, soldiers on military operations, and on-call doctors - can be chronically...
