Often adjustability is used in design contexts where a range of sizes is not possible or expensive to produce.
#Anthropometrics graphical analysis driver#
Car driver seats have many adjustments that can accommodate many people, eg seat height, distance to sterling wheel, even height of the steering wheel.Term: Adjustability: The ability of a product to be changed in size, commonly used to increase the range of percentiles that a product is appropriate for. Term: Reach: A range that a person can stretch to touch or grasp an object from a specified position. eg: two people in a doorway or the space between sitting people.Term: Clearance: The physical space between two objects. Which is the longest arm length and which group do they belong to?.Identify the sitting height of the 50th percentile.Interpret percentile tables in order to calculate dimensions related to a product.If a product is in short use and safety or comfort such as a school desk or waiting room seating, then the 50th percentile would be appropriate.For example motorcycle helmets need to fit snugly in order to function properly in protecting the head. If comfort or safety are important than a range of percentiles must be considered.When considering percentile ranges the design context factors in as well.interpret percentile tables based on different national and international populations, gender and age.Take note of when dynamic or static data is used. Ergonomic4schools’ Anthropometry section has a nice table showing design contexts.In the table (Male Rowers) below of the lightest (least heaviest) rowers are the 5th percentile and they weigh 69.8 kgs or less.Consider the 5th, 50th and 95th percentiles in particular, and percentile ranges such as 2.5th to 97.5th and 5th to 95th.You need to be able interpret percentile tables for user populations in a design context.Term: Percentile range: That proportion of a population with a dimension at or less than a given value. Body shape and sizes can change over time.Age, gender, ethnicity, etc need to be considered.Reliability and limitations collecting anthropometric data. It is collected and stored in databases or in books.There is a great deal of anthropometric data available.Term: Secondary data: Data collected by someone other than the user. It is collected by the researcher or designer themselves.This would be carried out if there is a specialised group of people that may not have been studied.Term: Primary data: Data collected by a user for a specific purpose. Can opener – requires the dynamic data of grip and torque.īutterfly Can Opener – can be hard to use for some people.Įrgonomically designed – big easy grip handles and wing nut.Īctivity: On the Padlet match 1 dynamic and 1 static data with a design context.
