7.2 Anthropometric Data
1. Determine the User Population
Measurement of Data
No one is exactly average
Anthropometer - measures distance between two body landmarks
Standardized measurement devices and methods
must pay close attention to the charts and where they are referring to.
Civilian and Military Data
Military data is public (paid for by the government)
Civilian data is private
Types of Data
Structural and functional data; in the chart if there is a parenthesis, it comes from a non military source.
Static data, or stationary.
Body is in standard and still positions
Dynamic data, or moving positions
Body adopts various working postures
Steps of Using the Data
2. Determine Relevant Body Dimensions
Determine the percentage of the population to be accommodated.
Extremes - everyone must use, ex. doors
Clearance - use 95% male measurements
Reach - use 5% female measurements
Safety - accommodate 100% of the population
Adjustable Range - if possible
Average - last resort, one size fits all
4. Determine the percentile value of the selected anthropometric dimension
Lower Limit of
- can't be smaller or ill be unusable by the largest person
- High percentile
- ex. door
Upper Limit of
- can't be larger or will be unusable by the smallest person
- Low percentile
- ex. button in a car
5. Make necessary design modifications to the data from the anthropometric tables
Changes due to wearing gloves/shoes/etc
Adjustment in calculations for things like clothing and conversions from static to dynamic data.
6. Use Mockups or simulators to test the design
