HUMAN FACTORS HANDBOOK: Ergonomics, Cognitive Performance, and Error-Resistant System Design for Practicing Engineers

The equipment worked exactly as specified, and people still made costly mistakes.

Engineers are trained to express loads, signals, and tolerances in numbers, yet the human side of a design is often left to opinion, warning labels, and late-stage training. Controls that violate expectations, displays that bury the critical value, lifting tasks that overload the spine, alarm floods that teach operators to ignore alarms, and schedules that exhaust the people who run a plant are rarely the work of careless individuals. They are mismatches between a specification and the people who must live with it.

This handbook brings the human side of design into the same quantitative, testable language engineers already use. Each principle is stated precisely, each equation is defined with its variables and units, and each method is demonstrated through worked calculations you can reproduce and adapt to your own problem.

Inside, you will learn how to:

1. Estimate whether a person can respond in time with a response-time budget, and judge when a function should be automated
2. Size workplaces and equipment for a stated proportion of a user population, without the common mistake of adding percentiles
3. Assess manual lifting, energy expenditure, noise, vibration, lighting, and heat stress with established calculation methods
4. Specify legible displays, well-coded controls, and alarm systems that operators can actually handle
5. Quantify human error probability, dependence between checks, and recovery, then design systems that tolerate the errors that will occur
6. Plan task analyses, usability tests, and verification so human performance requirements can be demonstrated

Key topics include the senses, information processing and decision making, memory, workload and situation awareness, motor control, body-size accommodation, biomechanics, work physiology, workstation layout, the physical environment, display and control design, human-computer interaction and automation, human reliability analysis, teams and safety management, and evaluation methods.

Written for mechanical, industrial, electrical, software, systems, safety, and reliability engineers, and for advanced engineering students and practitioners entering the field. No background in psychology or physiology is assumed; comfort with algebra, logarithms, elementary statics, and introductory probability is enough.

Add this practical engineering reference to your library and start designing for the people who will operate, maintain, and depend on your systems.
