Applying Standard Poses

ascenari.gif (1364 bytes) This task describes how to easily apply standard poses to a manikin without using the compass.
This feature is particularly intended for positioning the spine as a whole in order to apply squatting, stooping, twisting, leaning, and adjusted elbow postures.
  • Use the Restore Posture button in each tab of the Standard Pose dialog box to return the manikin to the posture it had before entering the tab.
  • Edit manikin posture by typing in the desired value or by using the spinner arrows. Press the Enter key. In both cases, the posture is updated automatically. You can also change the step value of the spinners by right-clicking the spinner arrows; the contextual menu appears as follows:

  • 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. This option cannot be used in the Hand Grasp and the Adjust Elbow tabs.
 
  • The Display function contains the Animate Viewpoint option. This option zooms on the manikin and changes the viewpoint in order to provide the best possible view of the working posture.
Select the Standard Pose and select the manikin in the scene or from the specification tree. The Standard Pose dialog box appears.

The standard poses are:

Sit

This tab includes two editors to quickly set the height and depth of the sitting posture.

Squat

This tab includes an editor to quickly set the height of the squatting posture.

Stoop

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 will rotate around the hips. Both pelvis and trunk rotation can be performed independently of each other but cannot be used together.

Whole Spine

Thoracic Section

Lumbar Section

Twist

This tab includes an editor to quickly move the whole spine in forward kinematics (DOF 3, i.e., left/right rotation).

Lean

This tab includes an editor to quickly flex the whole spine laterally in forward kinematics (DOF 2, i.e., lateral flexion).

 

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.

Also, you are able to store the latest Grasping posture angle specified in the Standard Pose dialog box for each posture type: spherical, cylindrical and pinch.  These values will be then use as the default posture of the Hand Grasp command. See Keeping the Settings of a Hand 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

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.
