Five Steps For Ergonomic Workstation Design

Truck drivers tend to be heavier than average; coal miners have larger torso and arm circumferences. Self-evaluation and self-selection play important roles. Army soldiers.

Found that some dimensions ex: body weight, shoulder breadth still show trend of growth while others do not show considerable change ex: leg length. Suggests a need for: updated anthropometric databases and corresponding changes in the equipment design. Mean measure of central tendency.

ANTHROPOMETRICS AND ERGONOMICS

Standard deviation degree of dispersion in a group of measured scores. Percentiles help to estimate the percentage of the user population that will be accommodated by a specific design. A seat surface designed using the 50th percentile value of the hip breadth of U. In a normal distribution, the 50th percentile value is equivalent to the mean of the distribution. Anthropometer with curved branches, d. Sliding compass c.

Spreading calipers. Person being measured required to adopt a standard upright, straight posture specified by a measurer.

Subject is placed in front of the surfaces and body landmarks are projected onto grids for measurements. Most surveys carried out with special populations e. Used U. Functional dynamic data measurements are obtained when the body adopts various working postures Example: area that can be reached by the right hand of a standing person standing reach envelope. Most anthropometric data are static, although work activities can be more accurately represented by dynamic data.

Who is going to use this data? Who will use the product or workplace? Determine the relevant body dimensions. Which body dimensions are most important for the design problem? Determine the percentage of the population to be accommodated. Design for extremes Design for adjustable range Design for the average. Which percentile value should be used: 5th, 95th, or some other value?

Engineering Anthropometry and Work Space Design

Need to be clear whether designing a lower or upper limit. Make necessary design modification to the data from the anthropometric tables. Most anthropometric measures are taken with nude or nearly nude persons. Adjustments need to be made to accommodate real-life situations e.

Use mock-ups or simulations to test the design. Critical to include a representative sample of users. Work-space design is one of the major areas in which human factors professionals can help improve the fit between humans, machines, and the environment.

The study of anthropometry has had some less-than-scientific applications throughout history. For instance, researchers in the s used anthropometrics to analyze facial characteristics and head size to predict the likelihood that a person was predisposed to a life of crime when in reality, there was little scientific evidence to support this application. Anthropometry has also had other, more sinister applications; it was incorporated by proponents of eugenics, a practice that sought to control human reproduction by limiting it to people with "desirable" attributes.

In the modern era, anthropometrics have had more practical applications, particularly in the areas of genetic research and workplace ergonomics. The typical body measurements used in anthropometrics include height, weight, body mass index or BMI , waist-to-hip ratio and body fat percentage. By studying the differences in these measurements among humans, researchers can assess risk factors for a host of diseases.

Ergonomics is the study of people's efficiency in their working environment. So ergonomic design seeks to create the most efficient workplace while providing comfort for the people within it. For the purposes of ergonomic design, anthropometrics offers information about the average human build. Desk manufacturers can build desks that don't force workers to hunch in uncomfortable positions, and keyboards can be designed to reduce the likelihood of repetitive stress injuries like carpal tunnel syndrome.
