Sit
- Translation
- This tab includes two editors to quickly set
the height and depth of the sitting posture.
- Display
- The Display option zooms on the manikin and changes
the viewpoint in order to provide the best possible view of the
working posture.
- Constraints
- Constraints can be used to freeze sections required of the manikin.
Use the Constraints check boxes to freeze the
positions of the hands and the direction of vision while the
rest of the manikin is moving. Note:
This option cannot be used in the
Hand Grasp and the Adjust Elbow tabs.
Squat
- Squatting
- This tab includes an editor to quickly set the
height of the squatting posture
Stoop
- Stooping
- This tab includes an editor, a pelvis option,
and a trunk option.
Trunk (default): The
manikin's spine can be manipulated as a whole or as sections.
You can choose which section of the spine (whole spine, lumbar
section, or thoracic section) to flex/extend (sagittal plane) in
forward kinematics (DOF 1).
Pelvis: The manikin's trunk can be bent with pelvic
rotation; the pelvis rotates around the hips. Both pelvis
and trunk rotation can be performed independently of each other
but cannot be used together.

The stoop posture of a Manikin Human Task stores the manikin posture in terms of DOFs of the various segments. Previously the model used by HTD is not extensive to store postures relating to Pelvic bend and rotation about manikin X-axis. Therefore, additional DOFs are needed to store the pelvic bend and rotation about manikin X-axis in posture part of manikin. Previously, It was not possible to distinguish the below set of postures without the stoop angle of the manikin.

Rotation about X-axis

Pelvic Stoop

Rotation about X-axis

As of now these postures are identified based on the orientation of manikin X-axis and manikin Y-axis in the world co-ordinates and this is not a fool proof mechanism in copy/paste scenarios. Two attributes now are provided which store the incremental angle of rotation about the manikin-Y axis and manikin X-Axis as shown in the picture below. The default value of these attributes is zero.

Rotation about X-Axis |

|
The attribute storing the incremental rotation about manikin Y-axis is populated when the stoop posture is attained using the pelvic rotation in Standard Pose command. Those values also can be defined by using IK mode to manipulate manikin's pelvis. |
The attribute storing the incremental rotation about manikin X-axis would be populated when the manikin phantom is rotated with feet constrained on the ground in IK command as shown in the picture below.
Twist
- Twist
- This tab includes an editor to quickly move the
whole spine in forward kinematics (DOF 3, i.e., left/right
rotation).
Lean- TorsionX
- This tab includes an editor to quickly flex the
whole spine laterally in forward kinematics (DOF 2, i.e.,
lateral flexion).
Hand Grasp
- Hand Grasp
- Three
types of hand grasps are included in this option: cylindrical
grasp, spherical grasp, and pinch grasp. The grasps can be done
with the left or right hands independently, or with both hands
together. Use the editor to loosen or tighten the grasp.
This option can be used with the forearm model.
Constraints are not available in this tab.
This dialog box works in conjunction with the
Manikin Hand Grasp Toolbar.

Adjust Elbow
- Elevation
- This tab includes an editor to quickly adjust
the elevation, up or down, of the right or left elbow. This is
used to adjust the elbow while keeping the selected hand and
shoulder at a fixed position.
