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.

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.
