Segments
- Segments
- This is a list of human body segments corresponding to the
selection made in the part menu. Select the name of the segment in the list to
select it. The
Arm is selected.

Segment selections are:
Arm, Clavicular, Foot, Forearm, Full Spine
(Lumbar+Thoracic), Head, Leg, Line of Sight, Lumbar.
Hand Filter
- Hand Filter
- Selecting the Hand Only option, only the hand is available in the
Segments multilist. Selecting the Hand and Fingers option, all the fingers
are also available in the Segments multilist.
Side
- 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.
Degrees of Freedom
- Degrees of Freedom
-
From the
Degree of Freedom list, you can choose
from three types of
DOFs:
- Flexion/extension
- Abduction/adduction
- Medial rotation/lateral rotation
When the Posture Editor dialog box opens, the
Degree of Freedom field in the dialog box is
grayed out, and has DOF0 as its field value. This changes to the default
value flexion / extension only when one of the segments selects.
A segment can have up to three DOFs. Examples of possible
segment DOFs are: The forearm has two DOFs: flexion/extension and
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:

Value
- Value
- Use the Value functionality to assign a precise posture to a segment.
The value of the DOF represents in an 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. Edit this value directly by
sliding the cursor with the left mouse.
Value spinner
Right clicking in the Flexion window 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 context menu. Selections are Change step, Measure Between, and Measure
item.
Motion
The motion field corresponds to the direction of movement, 0 degrees
being the neutral point, flexion, or
extension.
Coupling:
The range of motion (flexibility, functional limitation) for six pairs of
segments on the manikin could couple, that is,
conditional to the position of another joint. These segments are: the
clavicular, 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
Reset DOF - This resets the degree of freedom.
Note:
The current position of referential is honored when
Reset DOF is called.
Display
- Display
- The Display function has two options: Angular Limitations and
Animate Viewpoint.
Angular Limitations (chart)
Angular Limitations (chart)
This verifies displays or hides the graphical representation of the
angular limitations for each degree of freedom.
Two arrows limit this range of motion, which is specify by default at the
50th percentile of the population.
- The green arrow that shows the upper limit.
- The yellow arrow that 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 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
- Predefined Postures
-
Use the Predefined Postures functionality to assign a predefined
posture to the worker. Select the six available postures:
- Stand Relax.
- Stand.
- Sit.
- Reach.
- Kneel.
- Stand Ready.
- Sit Relax.
