Lecture 6: Engineering Anthropometry and Workspace Design Flashcards
What is anthropometry?
study and measurement of the human body
What does anthropometry provide?
fundamental basis and quantitative data for matching the physical dimensions of workplaces and products with the body dimensions of intended users
How much of the population is design intended for?
90th percentile
What are three considerations for design?
efficiency, effectiveness, and safety
What are some factors affecting human variability?
age, generational, gender, body position, diurnal transients, occupational variability, clothing, ethnic groups
What does a percentile value of an anthropometric dimension represent?
the percentage of the population with a body dimension of a certain size or small
What are the steps to using anthropometric data in design?
determine user population
determine relevant body dimensions
determine the percentage of the population to accommodate
determine the percentile value of the dimension
design to anthropometric data
usability test to evaluate the design
What is the Accommodate Clearance Requirement of Largest Users Principle?
clearance dimensions are lower limit dimensions and should be adequate for the largest users who are planning to use the workspace
What is the Accommodate Reach Requirement of Smallest Users Principle?
the reach envelope can be accessed without leaning forward or stretching
What are some adjustments to consider in the Adjustability Principle?
adjust the:
workplace
worker position
workpiece
tool
What is the Line of Sight Principle?
design where eyes gaze 10-15° below the horizontal plan
What are some considerations for the Component Arrangement Principle?
consider frequency of use
consider importance
consider sequence of use
be consistent
Co-locate related controls and displays
avoid clutter
group by function
