Human Posture Analysis - Mirror Copy

Mirror Copy

The mirror copy function will copy the preferred angles of the selected segment (in all degrees of freedom) onto the opposite side of the manikin.

Mirror copy functionality can only be applied to segments that have an equivalent segment on the other side. If there is no equivalent segment, Mirror Copy will be disabled in the contextual menu. It is also disabled in the contextual menu when you select the entire manikin or the "Body" node.

Swap

The preferred angles of each selected segment will be copied to the opposite side of the manikin and vice versa. If a segment does not have an equivalent on the opposite side, Swap will be disabled in the contextual menu.

Using and Optimizing the Postural Score

This procedure describes how to use the List and Chart displays in the Postural Score Analysis dialog box and optimize the postural score. It also describes how to set segment coloring and how to customize the list and chart display in the Postural Score Analysis dialog box.

The postural score feature is used to evaluate the manikin's posture. Once the preferred angles have been specified or loaded from a library, you can evaluate the posture using the postural score function.

Click the Postural Score Analysis icon.  The Postural Score Analysis dialog box is displayed with 

the List display as default.

This combo lists the specific DOFs that may be chosen as well as the choice of an average of all DOFs.

●     Spine and Hand

❍     Choose the Whole Spine option to see all vertebras as one element. The score of that element will be the average score of all vertebras. This is the default.

❍     Choose the Each Vertebras option to see and score each vertebra individually.

❍     Choose the Whole Hand option to regroup each part of the fingers into a global element. This is the default.

❍     Choose the Each Fingers option to see and score each finger individually.

Using the List display

This is the default display and shows the percentage scores as a list. Both the List view and the Chart view contain the following elements:

●     Global Score Represents the total score of the posture for all the segments combined. In this example, the manikin scores 11 points out of a possible 22, representing 50.00%.

●     Current Score Gives the average score of all the items currently displayed in the list.

●     Selected Score Represents the score of the posture for all selected items on the multi-list. In this example, the local score is 7 points out of a possible 9, representing 77.78%.

●     Favorites Customizable, this displays preferred angles that are always displayed even if they have never been edited. By default a segment with a preferred angle is displayed even if it is not in the Favorites list.

Customize this in the Tools->Options->Ergonomics Design->Human Posture Analysis>Postural Score tab. The first Display field lists available segments. 

❍     Choose one or select more than one using the Ctrl key.

❍     Move them into back and forth from the Available field to the Favorites field with the  and  buttons.

❍     Use the  and  buttons to move entire lists back and forth.

❍     Use the  buttons to move favorite segments up or down in the sorting order.
