Ergonomics and human factors

Ergonomics and human factors

Fundamentals of Ergonomics

  • Definition of ergonomics: This is the scientific discipline concerned with understanding the interactions among human beings and various system elements, aiming to optimise human well-being and overall system performance.
  • Human factors: These refer to environmental, organisational and job factors, including human and system capacities, which impact behaviour at work in a way which can have an impact on health, safety, and performance.
  • Harnessing ergonomics: In design engineering, ergonomics is applied to ensure that a product is safe, comfortable, and efficient to use.

Human Body and Ergonomics

  • Anthropometrics: This is the practice of measuring the human body’s physical dimensions and capabilities, which designers use when developing products to ensure compatibility with the user’s body.
  • Biomechanics: It’s the study of the mechanical laws relating to the movement or structure of living organisms, playing an essential role in understanding physical user-product interaction.
  • Physiology and psychology: Both the physical and mental capabilities and limitations of humans should be considered in product design, such as strength, sensitivity and response times.

Designing with Ergonomics

  • User-friendly designs: Ergonomics assists in developing user-friendly products and design spaces by taking into account the users’ needs, abilities, limitations, and preferences.
  • User experience: Ergonomic designs improve user experience by increasing product utility, effectiveness, and reliability, ultimately leading to higher customer satisfaction and product success.
  • Design for all: It focuses on developing products that are accessible and usable by as many people as possible without the need for adaptation or specialised design.

Ergonomics and Efficiency

  • Workplace ergonomics: Applies to designing an efficient and safe work environment by adjusting the operating settings to meet the user’s capabilities.
  • Usability evaluation: Involves determining how well users can accomplish tasks using a product, which gives important feedback to engineers for product improvement.
  • Risk analysis: Used to identify and mitigate potential hazards related to poor ergonomic design. Covers everything from slips, trips and falls to repetitive strain injuries and musculoskeletal disorders.

Ethical Considerations in Ergonomics

  • User safety: Ensuring product safety is a key element of ethical design principles, one which ergonomics contributes to substantially.
  • Inclusivity in design: Ethical principles require the designers to create inclusive products that cater to the needs of all users, including those with unique physical or psychological requirements.
  • Sustainability and ergonomics: A sustainable product means considering the environmental impact, but also designing a product that won’t break or become uncomfortable quickly - this leads to more thoughtful consumption habits and less wastage.
