Performing a Human Posture Analysis

OverviewHuman posture analysis focuses specifically on examining how human posture

can affect task performance by analyzing the following:

Local Posture

Global Postu re

Preferred Ang les

Comfort and Strength

Human Posture analysis allows you to both quantitatively and qualitatively analyzeseveral aspects of human posture. Posture can be examined, scored, and optimizedto determine the optimal operator comfort and performance throughout a completerange of motion during the task. In addition to the various postures, you can alsoanalyze the effects of posture on individual segments of the manikin.

When you have finished analyzing posture data, you can create and save comfortand strength libraries that can be reused throughout various applications.

Using the

Human Posture

Analysis

Workbench

The Human Posture Analysis workbench provides the following tools foranalyzing manikin posture:

Angular Limitations Toolbarthis toolbar allows you to set restrictions on the upper and lower limits

of movement (in degrees) on a particular segment of the manikin.

Preferred Angles Toolbarthis toolbar allows you to create or edit preferred angles within the whole

manikin range of motion. For example, preferred angles can refer to areas where the manikin wouldbe more comfortable or stronger or be in a safer posture.

Saving Manikin Attributes Toolbar

this toolbar allows you to save the preferred angles that you have

created.

Postural Score Panel Toolbarthis toolbar allows you to review postural score results in a variety of

ways.

Displaying the Postural Score Procedure


From this window, you can choose

which degree of freedom (DOF) to

display, whether you want to display

results in either List or Chart form,

and you can apply filters as

necessary.

You can also create a customize jointusing a set of upper body segments,

including the spine and head.

The layout of the Postural Score Analysis dialog box might change depending on

the various selections you make.

You can select fromthe following filters: Spine and Hand:

Select Whole Spine to score all vertebrae as a single element.

Select Each Vertebras to score each vertebra individually.

Select Whole Hand to regroup each finger into a global element.

Select Each Fingers to score each finger individually.
