PrefaceHuman Posture Analysis is based on a best-in-class human modeling system which, for many years, has permitted detailed investigation into human-centered design issues in the context of a workplace before it physically exists. Human Posture Analysis focuses on how human posture can affect task performance by analyzing local and global postures, preferred angles, and comfort.

Human Posture Analysis permits users to quantitatively and qualitatively analyze all aspects of manikin posture. Whole body and localized postures can be examined, scored, iterated, and optimized to determine operator comfort and performance throughout the complete range of task motion in accordance with published comfort databases.

User-friendly dialog boxes provide postural information for all segments of the manikin. Color-coding techniques ensure that problem areas can be quickly identified and iterated to optimize posture. Human Posture Analysis allows users to create specific comfort and strength libraries to meet the needs of individual applications.

and choose whether or not to set the referential to a compass location.

4. If you already have an active product containing a manikin, select the manikin or double-click a segment.


User TasksThese are the tasks that a user performs using Human Posture Analysis:


Using the Posture Editor

This task describes the functions of the Posture Editor and how to use them to move manikin segments.

The Posture Editor is a tool used to move manikin segments in forward kinematics. The segments or degrees of freedom (DOF) are moved one step at a time. This tool allows you to give a precise value to each degree of freedom of every joint.

The manikin's structure consists of 68 articulated joints with 6 coupled joints (range of motion can depend on the position of a neighbor joint).

1. Select the Posture Editor icon. The Posture Editor dialog box

is displayed on the screen when the manikin is selected.


The Posture Editor dialog box is divided into five sections:

The Degrees of Freedom can be modified either through the Value section or through their graphical representations.


Segments

This page describes the Segment section functionality of the Posture Editor dialog box.

Displayed below the manikin name is a list of human body segments corresponding to the selection made in the Part menu. Click on the name of the segment in the list to select it.

Part:


The Part options menu allows you to choose the category of body segments to edit on the manikin The three categories listed are:

1. Hand:Edit the segments of the hand including the center of prehension.

2. Spine:Edit the segments making up the spinal column of the manikin.

3. Other:Edit all articulated segments excluding hand and spine segments. Other is the default option when the dialog box opens.

Side:

When you edit certain segments such as the arm, you can choose which side you want to work with: Left or Right.

Left is the default option when the dialog box opens.


Degree of Freedom

This page describes the Degree of Freedom (DOF) functionality of the Posture Editor dialog box.

1. From the Degree of Freedom list, you can choose from three types of DOFs:

● flexion/extension

● abduction/adduction

● medial rotation/lateral rotation

The default when the dialog box opens is flexion/extension.


A segment can have up to three DOFs. Examples of possible segment DOFs are:

● The forearm has two DOFs: ❍ flexion/extension

❍ pronation/supination

● The arm has three DOFs ❍ flexion/extension

❍ abduction/adduction

❍ medial rotation/lateral rotation


Each of the DOF types, flexion/extension, abduction/adduction, and medial rotation/lateral rotation, also have specific movement types. These are:

DOF Movement Type Axis

flexion

extension

dorsiflexion

hyperextension

transversal

abduction

adduction

eversion, ulnar deviation, elevation

inversion, radial deviation, depression

sagittal

medial rotation

lateral rotation

supination

pronation coronal


Value

This page describes the Value functionality of the Posture Editor dialog box.

Use the Value functionality to assign a precise posture to a segment. The value of the DOF is presented in angle and in percentage of the total range of motion (%).

Value percentage slider


The percentage (%) slider corresponds to the value in percentage of the total range of motion for the selected DOF. This value can be edited directly by sliding the cursor with the left mouse button.

Value spinner

This field allows you to enter a specific value in degrees using the keyboard. You can increment or decrement to segment rotation one unit at a time using the small arrows at the right end of this field. You can also change the step by using the spinner's contextual menu.

Motion

The motion field corresponds to the direction of movement, 0 degrees being the neutral point.

Coupling:

The range of motion (flexibility, functional limitation) for six pairs of segments on the manikin can be coupled, i.e., conditional to the position of another joint. These segments are: the claviculars, the arms, the forearms, the thighs, the legs, and the ankles.

Coupling modifies the range of motion of these segments only. It has no effect on any relationship that may exist between other body segments.


By default, coupling is inactive.


Display

This task describes the Display functionality of the Posture Editor dialog box.

The Display function has two options: Angular Limitations and Animate Viewpoint.

Angular Limitations (chart)


This check button displays or hides the graphical representation of the angular limitations for each degree of freedom.

Two arrows limit this range of motion, which is set by default at the 50th percentile of the population.● The green arrow shows the upper limit

● The yellow arrow shows the lower limit

● The blue arrow represents the segment's current position

Animate Viewpoint

This option zooms on the selected segment and changes the viewpoint in order to provide the best possible view for that degree of freedom. This improves the range of motion chart display and as well as the capability to better manipulate the blue arrow.


Predefined Postures

This task describes the Predefined Postures functionality of the Posture Editor dialog box.


Use the Predefined Postures functionality to assign a predefined posture to the manikin. From the Predefined Postures list, choose from the six available postures.

Stand

Sit


You can also select the manikin node in the specification tree. Right-click the mouse to activate the contextual menu and choose Posture->Sit.


Reach


Extended Reach


Span


Kneel


Selecting or Editing the DOF (degrees of freedom)

This procedure describes how to select or edit the manikin's DOF (degree of freedom).

The DOF icon represents the movement being edited. For example, the DOF can be flexion/extension, abduction/adduction, rotation, etc.

1. Click on the Activate DOF icon to access the list of all available

DOFs corresponding to the active segment (maximum of three).

2. Click one icon to select the corresponding DOF.

3. The system automatically modifies the viewpoint of the segment by a zoom corresponding to the DOF being selected.

DOF1

DOF2


DOF3



This procedure describes how to display the values of the angular limitations for the DOF (degrees of freedom) that is currently active. It also describes how to set angular limitations as a percentage.

1. Select the Edit Angular Limitations icon and then select a segment.

The limits arrows are displayed. These arrows are set by default at the mean values of movement limits. The colored region represents the total range of motion for that DOF.

● The green arrow shows the upper limit.

● The yellow arrow shows the lower limit.

● The blue arrow is used to change the position of the active segment.

Selecting another segment while the command is running opens the angular limitations for the new segment and closes them for the previous one.


2. When you double-click the limits arrows, the Angular Limitations dialog box appears (see below).

Using this dialog box, you can unlock the angular limits and modify the values directly with the sliders, the spinners, or by using the left mouse button to manipulate the spinner arrows.

● Select the Reset button to return to the default values.

● Select the Close button to exit the dialog box.

3. Select the Edit Angular Limitations icon to close the command and

hide the angular limits arrows.

Setting angular limitations as a percentageWith this command, you can change the angular limitations of one or many degrees of freedom at once according to the percentage you choose.

This percentage value represents the desired portion of population that must be able to reach the limit. At manikin creation, all angular limitations are set to limits that 50% of the population can reach. Using the Set Angular Limitations as a Percentage command, you may want to restrict (i.e., accommodate a narrower percentage of population) or widen (i.e., accommodate a larger percentage of population) these limits for a specific requirement of the population study.

1. Select a segment of the manikin. Hold down the Ctrl key on the keyboard to select more than one segment.


2. Select the Set Angular Limitations as a Percentage icon. The following

dialog box is displayed:

A read-only text field show the currently selected segments (or lines of sight) and their current degree of freedom.

3. Choose a percentile between 0 and 100 with the spinner.

4. Click on OK to confirm the modification of press Cancel to cancel the action. By clicking OK, both limits (min and max) of all degrees of freedom selected will take the specified percentage.

The modification cannot be done if the selected degree of freedom is locked with a value that would be outside the new limits. In this case, the following dialog box is displayed:


Angular Limitations Undo/Redo

This procedure describes how to use the Undo/Redo feature with angular limitations. Undo/Redo allows you to reverse (cancel) the last angular limitation parameters applied to the manikin.

Undo

Click the Undo icon in the Standard toolbar to execute the Undo command. To load

a library of angular limitations, see the library management task, Load Angular Limitations.

The images below show the state of a manikin after applying the Undo command to a particular set of angular parameters.

Initial angular limitations

New angular limitations applied

Undo command applied

Redo

This command repeats the last cancelled action. Click the Redo icon in the main

menu toolbar to execute the Redo command.

A Redo operation can also be undone. For example, you can restore the last angular


limitation parameters by invoking the Undo command.

Redo applied Undo applied

In the current version of the Human Posture Analysis product, the angular limitations Undo/Redo applies to the following operations: ● Applying a set of angular limitations from a library .


Direct Kinematics

This procedure describes how to manipulate manikin segments.

When you select the Edit Angular Limitations icon or the Edit

Preferred Angles icon a blue arrow is displayed. You can change

the position of the active segment by manipulating the blue arrow.

The cursor changes to pickable when it is moved over the blue

arrow. Press and hold down the left mouse button to manipulate the blue arrow and the segment.


Selecting Manikin Display Attributes

This procedure describes how to access the various display attributes available for your manikin.

1. Select the Display Attributes icon . The Display Attributes

dialog box is displayed.

3. Various attribute display types can be selected at the same time.

Segments


Ellipses


Surfaces


4. The line of sight is designed to facilitate the manipulation of the manikin's field of vision. It can be selected as any other segment of the manikin.


5. The center of gravity cannot be selected and manipulated. If you manipulate any segment of the manikin, the center of gravity is dynamically updated.

6. By default, the manikin display is set to surfaces with a resolution of 32. The range of this parameter is from 4 to 128.

Surface resolution: 4


Surface resolution: 128


Library Management

This procedure describes the commands that allow you to create, read, and update angular limitations and preferred angles libraries.

A library is a collection of manikin-related data (i.e., postures, angular limitations, anthropometries, preferred angles, etc.) saved into a binary file. This file type usually bears the extension .swl.

The two library management commands are:


Load Angular Limitations

This command allows you to load an existing library file.

1. Select the Load Library icon . The Open Human Library File


2. Enter a file name and click Open. The Load Human Library dialog box is displayed showing the contents of the selected file.


3. Select an item and click Apply (or double-click the item). The progress indicator at the bottom of the window shows the load action. Depending on the type of item selected, select the Edit Angular Limitations icon or the Edit Preferred Angles icon

to display the newly loaded values.


4. Select an item in the list and click on Remove to remove the item.

5. Select Close to exit from the dialog box.

5. Click OK. The file is saved automatically and the progress indicator shows the save action. If the description is missing, an error window is displayed.

6. Select Cancel to exit the dialog box or to cancel the save action.


Locking and Unlocking Degrees of Freedom (DOF)

This tasks describes how to lock and unlock individual manikin degrees of freedom. Locking a degree of freedom means that the corresponding segment will not move by this DOF, either in forward kinematics or in inverse kinematics.

The Lock/Unlock command will lock/unlock the current active DOF on the selected segments. The current active degree of freedom is indicated by the DOF icon.

It is possible to lock/unlock the entire manikin for one particular degree of freedom if the Body node is selected in the specification tree when activating the lock/unlock command.

For more information on locking and unlocking degrees of freedom, read the following sections:● Locking DOFs

● Unlocking DOFs

A manikin must be created or imported to complete the following procedures.

Locking DOFs1. To lock a degree of freedom, select the lock icon and then select the

segment(s) to be locked. Multiple segments can be locked at the same time if they are pre-selected before the activation of the command.

If the operation is successful, a message window will appear displaying the segments that have been locked.


2. Follow these steps to discover the existing locked segments on a specific manikin:

a. Access the manikin Properties panel. To do this, right-click on the manikin from the product tree and select Properties.

OR select Edit -> Properties from the main menu.

5. Click the Edit Preferred Angles icon to cancel the command

and hide the arrows.


Preferred Angles: Reset, Mirror Copy, and Swap Functionality

This procedure describes how to copy and modify more than one set of preferred angles using these functions:

● Reset

● Mirror Copy

● Swap

For more information on preferred angles, see Editing Preferred Angles.

To access these functions, right-click on a segment, a segment node, a body, or a manikin.

The following contextual menu appears:


Reset

The preferred angles of the segments selected will be erased and will return to their default state.

The default state of the preferred angles in the following:● only one preferred angle on the angular limitation range

● a score of zero

● a white color

● a transparency of 127


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.

● Filters

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 ScoreGives the average score of all the items currently displayed in the list.

● Selected ScoreRepresents 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%.

● FavoritesCustomizable, 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.


Using the Chart display

Select the Chart radio button to view the percentage scores as charts. The Chart view also contains the same basic elements as the List display.

The text for selected segments are turn blue.

Customizing bar colors

To customize chart bar colors, select Tools->Options->Ergonomics Design->Human Posture Analysis->Postural Score tab. Colors may be individualized for the whole hand, the whole spine, the global score, the current score, and the selected score.


Segment Coloring

Access to segment coloring is through the Properties dialog box.

1. Right-click the manikin in the specification tree and select Properties from the contextual menu. The Properties dialog box appears.

2. In the Manikin tab, select the Coloring sub-tab.

● Show Colors:These radio buttons are used to enable and disable the coloring. ❍ None deactivates the coloring.

❍ All activates the coloring.

❍ All but Maximum Scores activates the coloring on all segments except those with scores at their maximum. This feature can be used, for instance, to display colors only if the manikin goes out of its comfort zone.

● Degree of FreedomThis combo is used to choose the degree of freedom to activate. This combo is enabled only if the coloring feature is active.


❍ Flexion/Extension (DOF1)The color shown for each segment is the color of the preferred angle defined for DOF1 of the corresponding segment, if it exists. Otherwise, no coloring is applied.

❍ Abduction/Adduction(DOF2)The color shown for each segment is the color of the preferred angle defined for DOF2 of the corresponding segment, if it exists. Otherwise, no coloring is applied.

❍ Rotation (DOF3)The color shown for each segment is the color of the preferred angle defined for DOF3 of the corresponding segment, if it exists. Otherwise, no coloring is applied.

❍ Worst DOFThe color shown for each segment is the color of the preferred angle defined for the lowest scoring DOF of the corresponding segment, if it exists. Otherwise, no coloring is applied.

● Element to color:These checkboxes are used to select the parts that will change color. They are enabled only if the coloring feature is active.

Optimizing the postural score

In the Preferred Angles toolbar, select the Find Best Posture command. This command changes

the position of the body so as to maximize the global postural score of the manikin (i.e., yield a perfect score).

If this command is invoked and there are no preferred angles or if the manikin is already in an optimal posture, the following message is displayed:


Adapting Range of Motion to Keep Best Posture

The purpose of this task is to set the angular limitations of the selected segments so that these limitations correspond to the best range of motion, that is, the range of motion where the postural score is the highest.

Please refer to Editing Preferred Angles for information on how to create preferred angles and assign scores to individual ranges of motion.

1. To optimize the range of motion of any particular set of segments, first select the desired segment(s) and then click on the Optimize Posture icon.

For each selected segment and for the current active degree of freedom, the command looks for all preferred angles created that have been assigned scores. The command then sets the angular limitations to the range containing the highest score.

When this command is run, the posture of the segment(s) may change in order to reflect the new angular limitations.

It is possible to use this command to optimize the posture of the manikin as a whole. To do this, select the Body node in the specification tree before activation the Optimize Posture command.

This is particularly useful if the manikin's movements must be restricted to the "comfort zone". The postural score of such a manikin will stay at its highest, no matter how the manikin is moved. For more details, please refer to Using the Postural Score.

It is possible that some or all of the selected segments may contain no preferred angle information or some of the angles may be locked. In these cases, and these cases only, the Optimize Posture command might fail. If the command fails for a subset of the selected segments, a message window will appear displaying the list of segments for which the optimization failed.


2. To reset the angular limitations of a manikin, select the segments that must be reset and click on the Reset to Default Angular Limitations icon.
