    Study Notes

    Ergonomics

    • Ergonomics is the study of the effect of health and safety in the working environment on productivity.
    • Bad working conditions affect productivity adversely, while good working conditions make workers more interested in their job.
    • The science that considers factors such as comfort and safety in workplace design is called ergonomics.

    Definitions of Ergonomics

    • Ergonomics is derived from the Greek words "Ergo" (work) and "Nomos" (natural laws).
    • Ergonomics is the study of relations between humans and their environment, occupation, equipment, and particularly, the applications of anatomical, physiological, and psychological knowledge to solve problems.
    • Ergonomics is the science of work that deals with the relationship between humans and their working environment, implying "Fitting the job to the worker."
    • Ergonomics is the process of designing or arranging workplaces, products, and systems to fit the people who use them.

    Objectives of Ergonomics

    • Enhance safety and reduce injuries by minimizing the risk of musculoskeletal disorders and preventing accidents.
    • Improve comfort by ensuring workplaces, tools, and equipment are comfortable to use, reducing physical strain and discomfort.
    • Increase productivity and efficiency by designing systems and workplaces that enhance productivity.
    • Enhance performance by improving the performance of tasks and facilitating better decision-making.
    • Improve the quality of work life by creating work environments that promote well-being and satisfaction.
    • Facilitate accessibility and inclusivity by ensuring products, environments, and systems are accessible to people with varying abilities and disabilities.
    • Support human-centered design by emphasizing the importance of designing systems around the needs and characteristics of users.

    Man-Machine System Interface (MMSI)

    • MMSI is the combination of humans and machines interacting to bring about the desired output from given input.
    • Components of MMSI include the human element, machine element, and interface.
    • Human element factors include capabilities, limitations, and physical and cognitive characteristics.
    • Machine element factors include hardware and software.

    Objectives of MMSI

    • Enhance efficiency and productivity by designing interfaces that are intuitive and reduce task time.
    • Ensure safety by designing interfaces that provide clear and timely feedback, preventing user errors and enhancing safety.
    • Improve usability by creating user-friendly interfaces that require minimal training and are easy to navigate.
    • Enhance user comfort by considering ergonomic factors such as posture, reach, and visual comfort.
    • Support decision-making by designing interfaces that present information clearly and concisely.

    Design Principles of MMSI

    • User-centered design: design should be based on the needs, capabilities, and limitations of the user.
    • Consistency: maintain uniformity in interface design.
    • Feedback: provide clear feedback to users about their actions.
    • Simplicity: keep the design simple and uncluttered.
    • Error prevention and recovery: design to minimize errors and provide ways to recover from them.
    • Affordance: design elements should suggest their functionality.
    • Accessibility: make interfaces usable by people with a range of abilities.

    Examples of MMSI Applications

    • Industrial control panels
    • Aviation cockpits
    • Medical devices
    • Consumer electronics

    Effect of Environment on Worker Performance

    • Lighting: proper lighting reduces eye strain and fatigue, improving focus and productivity.
    • Temperature and humidity: maintaining optimal temperature and humidity helps create a comfortable working environment.
    • Noise levels: high noise levels can be distracting, leading to reduced concentration and increased stress.
    • Air quality: poor air quality can cause respiratory problems, headaches, and fatigue.
    • Ergonomics: ergonomically designed workspaces can prevent musculoskeletal problems and reduce fatigue.
    • Color and aesthetics: colors can influence mood and energy levels, and aesthetically pleasing workspaces can enhance mood and reduce stress.
    • Workspace layout: the layout of a workspace affects communication, collaboration, and efficiency.
    • Access to nature: access to natural elements can reduce stress and improve mood and cognitive function.
    • Break and rest areas: providing areas for rest and breaks can reduce fatigue and improve concentration.
    • Psychosocial environment: a positive psychosocial environment with supportive leadership, clear communication, and opportunities for social interaction can improve morale and productivity.
