Two terms are used to describe the application of scientific information about human variability and adaptability to the design process. Ergonomics (also known as Human Factors) describes information about humans in 'working' situations. Anthropometrics deals with information about human body size and shape.
As an item of furniture is rarely used by only one individual, most furniture must accommodate the variations of a wide range of end users. The 'average' person is a mythical creature. Win big 21 casino no deposit codes. When measurements are taken from a target population for a particular design, a mid-point (termed the 50th 'percentile') divides users into two groups - one above and one below the 'average.'

It may be logical to use this mid-point/average number to determine the height of a chair seat but not the height for the top shelf in a storage cabinet. In the latter case, it is standard practice to use a dimension that accommodates 90 to 95 percent of users who can reach an object on the top shelf. Rocfall rocscience crack. The design ideal is to provide for adjustability and use anthropometric data to determine the upper and lower limits for the range of adjustments, e.g., for workstation chairs.
Furniture designers should have a library of texts (or software) on this people).
The data may be dated (the population may be changing year over year).
Technology changes, e.g., computer keyboards have a lower profile than traditional typewriters.
Country of orgin may affect the data.

Measurements are taken with nude subjects (normally, people wear clothes and shoes at work).
The Industrial Design Engineering program at Delft's Technical University makes available a database of anthropometry. Designers can search the DINED data for human body dimensions specified by age, sex, country or other factors.

Workstation information
The design of workstations requires the application of anthropometic and egonomic data. furniturelink has provided a sample of relevant data taken from the Marine Corps study (listed above) and other sources. furniturelink added the information for the angle of sight (Z) from various sources that recommended angles between 5 and 15 degrees. For simplicity furniturelink shows the popiteal height (F) measured to the same baseline as the compressed seat height. To adjust for shoe height, add 25 mm for men or 45 mm for women (1).
