How has human-factors engineering been applied to computer-assisted instruction?

Human-factors engineering is applied to computer-assisted instruction by utilizing the same core principles and methods used to solve other complex technological and social problems.1

In the context of human-factors engineering—which is recognized as a branch of bioengineering focused on optimizing the relationship between humans and machines—this approach seeks to integrate the user into the system through rigorous scientific methods rather than intuition. When applied to educational software, these principles ensure that the design of the human-machine interface accounts for human physical, mental, and behavioral capabilities.234

By leveraging insights from psychology and physiology, engineers aim to create systems that are effective, efficient, and satisfying for the learner. Because design decisions often require trial and error to address the unpredictable nature of human behavior, human-factors specialists use empirical techniques to identify and resolve mismatches between the learner and the instructional technology.42
