Human factors is an emerging applied design field that entails a synthesis of cross-disciplines from classical ergonomics (i.e., the science of work, system-person interaction, and functional/operational performance needs), and newer research gleaned from the allied fields of cognitive science, human physiological psychology, perception, learning, memory and brain behavior science, interaction/interactivity design, product design, media design, communication design, and information design. Human factors engineering recognizes (1) the intensely cross-disciplinary nature of the human-technology system designer’s role and the transcending cultural, economic, societal, and geopolitical importance of information utilization and knowledge generation, and (2) the field’s creative, protean, and dynamically-hybrid “human-centered, user-centered, and usage-centered” systems approaches that strives to integrate existing multi-disciplinary domains (i.e., change management, computer and information science, informatics and systems theory to management philosophy, law and ethics, human cognition and perception, human resources, usability design, industrial design, and ergonomics).
