Human Factors Engineering aims to improve the interaction between humans and their work environment, resulting in enhanced user experience, increased productivity, and reduced errors.

Human Factors Engineering emphasizes the importance of understanding human capabilities and limitations to design systems that are compatible with our physical, cognitive, and perceptual abilities.

Ergonomics is the branch of science that deals with the relationship between humans and their work environment, focusing on optimizing the efficiency and safety of work systems.

Physical ergonomic risk factors are physical aspects of the work environment that can lead to musculoskeletal disorders. Repetitive motions, awkward postures, and forceful exertions are common examples.

Cognitive load refers to the amount of mental effort required to perform a task. It can be influenced by factors such as task complexity, time pressure, and distractions.

User testing involves observing and collecting feedback from users as they interact with a product or system to identify usability issues and areas for improvement.

Error proofing involves designing products and systems with features that prevent or minimize the occurrence of errors. This can include using warning signals, providing clear instructions, and eliminating potential hazards.

Affordance refers to the perceived and actual properties of an object that suggest how it can be used. In Human Factors Engineering, affordances are considered when designing user interfaces to make them intuitive and easy to use.

Task analysis involves breaking down a task into its component steps and identifying the human factors requirements, such as the necessary skills, knowledge, and abilities, to perform the task effectively and efficiently.

Observation is a widely used method for collecting data on human factors issues in the workplace. It involves observing workers as they perform their tasks to identify potential hazards, inefficiencies, and areas for improvement.

Universal design refers to the process of designing products and systems that can be used by people of all abilities, regardless of their age, disability, or other characteristics.

Flexibility in use is a key principle of universal design, emphasizing the need for products and systems to be adaptable to different users and situations.

Human factors evaluation involves assessing the effectiveness of interventions designed to improve the interaction between humans and their work environment. This can include evaluating changes in productivity, safety, and user satisfaction.

Experimental studies are a rigorous method for evaluating the effectiveness of human factors interventions. They involve manipulating independent variables and measuring the impact on dependent variables to determine cause-and-effect relationships.

Safety engineering involves designing products and systems to minimize the risk of accidents and injuries. This can include incorporating safety features, providing clear warnings and instructions, and conducting risk assessments.
