Anthropometric information tools

From WikID

Eyes

As a component of the third years elective `Ergonomics in Design' a tool has been developed as aids at designing products around the eyes. This tool indicates which measures must be surveyed for designing three categories of products: products which only support on nose and ears (e.g. optical devices), products which make contact with the area around the eyes (e.g. security optical devices or goggles for underwater use) and products which are not carried on the head, but make contact with the area around the eyes (e.g. binocular or microscope).

The tool has not yet been filled with anthropometric data. It is the intention that this will happen in interaction with designing products. When the tool is used at a product design, data from the target group will be collected. These data can be stored in WikID (this wiki). Furthermore, comments on the tool can be given there: are all measures required to design the product indicated or are there still measures lacking? And how did you like working with the tool: is it user-friendly, what could be improved?

If you have used the tool, you are asked to supply the information concerning the collected data (with source indication) and concerning the usability of the tool. For background information the report of the design of the tool is available. The tool itself is printable Image:Inserts definitief.pdf

Facemasks and other headwear

In relation to course IO3015, Ergonomics in Design, given at the faculty of Industrial Design Engineering at Delft University of Technology, we performed a study for a method to measure all relevant facial anthropometric dimensions in order to design facemasks and other headwear.

Designing a facemask that fits properly on every face is difficult. This is due to the fact that faces are quite different from each other. Many facemasks have to be universal because sometimes the provision for a series of graded mask sizes is impossible or impractical. It is however important that facemasks fit properly so that in the long run health problems can be prevented. A poor fit of the face masks is not the only thing that gives problems. The strap affects the fitting performance almost as much as the shape and fit of the mask. Often these straps are not adjustable, which results in a mask that is either fitted too tight or too loose.

Landmarks

There are different landmarks that are important for the design of nose and mouth wear. Facial expressions such as laughing, yawning, coughing and sneezing change many of the baseline measurements and have to be considered as well while designing nose and mouth wear.

The most important facial landmarks, concerning the basic shape, are shown below. With these landmarks you can define the facial shape.
