Flashcards
0/25
Adjustability
Adjustability refers to the capacity of an ergonomic product or workstation to adapt to the dimensions and preferences of the user to optimize comfort and productivity.
Neutral Posture
A neutral posture is a comfortable working posture in which your joints are naturally aligned, helping to reduce the risk of stress and injury.
Repetition
Repetition refers to the number of times a person performs the same movement or sequence of movements over a period, which can potentially lead to fatigue and musculoskeletal disorders.
Workstation Layout
Workstation layout involves organizing and designing the work environment to allow for efficiency of workflow and reduction of unnecessary motion.
Force
Force refers to the physical effort required to perform a task or to control equipment or tools, and minimizing excessive force can help prevent injuries.
Task Rotation
Task rotation is a strategy used to reduce worker fatigue and exposure to repetitive tasks by periodically switching between different tasks.
Visual Ergonomics
Visual ergonomics is concerned with lighting and how it affects the visual performance and comfort of the workstation user, aiming to prevent eye strain and fatigue.
Cognitive Workload
Cognitive workload is the level of mental effort required to perform a task, which can be optimized to prevent errors and enhance performance.
Anthropometry
Anthropometry refers to the measurement of the size, shape, and proportions of the human body, used to design ergonomic products that accommodate a wide range of users.
Environmental Factors
Environmental factors include all aspects of the physical surroundings such as temperature, humidity, and noise, which can significantly impact comfort and performance.
Feedback
In ergonomics, feedback refers to the information returned to the user about the action they have taken, which is important for correction and learning.
Material Handling
Material handling in ergonomics concerns the safe and efficient movement, protection, storage, and control of materials throughout manufacturing, warehousing, distribution, consumption, and disposal.
Sit-Stand Workstations
Sit-stand workstations are designed to allow the user to alternate between sitting and standing positions, which can reduce the risks associated with prolonged sitting.
Biomechanics
Biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms, applied in ergonomics to understand how body movements can be optimized to prevent injury.
Ease of Use
Ease of use refers to the simplicity and intuitiveness of the design of a tool, machine, or process, enabling users to perform tasks efficiently and safely with minimal training.
Accessibility
Accessibility in ergonomics refers to the design of products, devices, services, or environments for people who experience disabilities, ensuring equal usage for all.
Work Rest Cycles
Work rest cycles involve designing a workflow that includes breaks and recovery periods to prevent fatigue and musculoskeletal stress.
Control Display Units (CDUs)
Control display units refer to the combination of the control (input device) and display (output device), designed ergonomically to optimize the interaction between human and machine.
Usability Testing
Usability testing is a method used to evaluate a product or system by testing it with representative users, often to improve the product’s ergonomic design.
Personal Protective Equipment (PPE)
PPE refers to protective clothing, helmets, goggles, or other gear designed to protect the wearer's body from injury or infection and can be optimized for ergonomics.
Haptic Feedback
Haptic feedback is tactile feedback technology which recreates the sense of touch by applying forces, vibrations, or motions to the user, enhancing user interface experiences.
Human-Machine Interface (HMI)
HMI refers to the point of interaction between the human user and the machine or system, aimed at effective operation and control.
Circadian Rhythms
Circadian rhythms are the natural, internal processes that regulate the sleep-wake cycle and repeat roughly every 24 hours, considered in ergonomic design to align with workers’ productivity and health.
Redundancy
In ergonomics, redundancy refers to the design principle where multiple elements perform the same function to prevent errors and enhance reliability.
Error Management
Error management involves designing ergonomic systems that are forgiving of user error, allowing for easy recovery and prevention of further mistakes.
