1.1a Anthropometrics Flashcards
What is anthropometric data?
Measurements of the body (eg. arm, height, weight, etc.) used by designers to best suit their design plans
What are the different measurements of anthropometric data?
Static measurements: measurements of length between different points on the body when the subject is still
Dynamic measurements: measurement of reach, movement + strength to determine the user’s physical capabilities and how they move in a space
What are the different types of data for collecting anthropometric measurements?
Primary data: when a designer collects first hand data
Secondary data: data collected by someone other than the designer
What are the limitations of anthropometric data?
Age, gender, ethnicity
What is a percentile?
Percentiles are used to show the value below which a certain group falls under (eg. the 25th percentile is where 25% of the population are at or below)
Why is taking the 50th percentile not suitable for all designs?
Averaging data or taking the mean percentile does not ensure a design is accessible for all users, it is excluding all people above the average
Percentile ranges for different contexts
Easy reach (5th)
Adequate clearance/ unwanted contact (95th)
Good match between user and product (5th-95th)
Comfortable posture (5th-95th)
Easy operation (5th)
Prevent items from being reached (5th-95th)
What is clearance?
The physical space between two objects
What is adjustability?
The ability of a product to be changed in size to suit a wider range of percentiles
What are the different measurements of reach?
Normal reach or maximal reach
What is normal reach?
The distance an individual could extend their arm comfortably, and can be accessed easily and repetitively
What is maximal reach?
The furthest distance a user could extend their arm, it is accessible but would require effort + would not be ideal for repetitive actions
