Jack 8.2 User Manual SIEMENS PLM SOFTWARE

Because this manual cannot begin to cover all of the features of Jack, a also

providedbegin considering ways in which you can effectively apply Jack in your job, even before you undertake the training.

Some of the areas where Jack excels are:

Creating a - : Jack gives you all of the advanced graphical tools for creating concept models or importing design data to the virtual world. Design changes

than in ours. Analyzing human factors in designs: Occupant or operator reach, fit, comfort, and vision are all important considerations in product designs. It is imperative to products are designed with consideration of the people that will use them! Sttirelessly perform operations in factories or offices to allow you to design the most safe, efficient, and productive workplaces possible. Evaluating maintenance operations: The maintenance phase of the lifecycle can be associated with considerable cost for many large systems. Therefore, it is critical to consider the safety and task feasibility for maintenance and repair personnel. Jack gives you the tools to evaluate maintenance operations even in the earliest product design stages. Training: Your design simulations can serve double duty: training operators, maintenance or military personnel long before products or facilities are even constructed. This is done without the danger and

real life Research: Jacks is a detailed link segment model with biologically accurate motion prediction and joint kinematics. Almost endless data can be retrieved from Jack. The Jack Toolkit and open API is an ideal location to tap into the framework of Jack or plug in your custom tools.

Jack provides the tools you need to model complex systems, to study their motions, and to simulate how humans will work with them. Our users are constantly finding new, unique applications for Jack, and we hope you will also!

Unlike many 3D design and visualization systems, Jack works natively with articulated figures. In simple terms, Jaobjects, just like in real life. Jack provides a very powerful system for modeling articulated figures. Of course, one of the most demanding applications in this area is the human body! The focus in the development of Jack has been centered on creating the most accurate human body model available in any system.

simulated humans that have proper biomechanical, anthropometric, and ergonomic characteristics. Jack humans look and act like real humans. Jack humans understand balance, walking, and lifting. They have

a task exceeds their limits. And if the action you define does exceed the limits, Jack can calculate a action You can model males and females of any stature, based upon validated anthropometric databases. Jack humans have the same joint limits (range of motion) as a typical human in the real world does. This sort of modeling, simulation, and analysis requires a powerful graphical viewing environment, an easy to use interface, and a complete set of command functions. Jack provides all of this. Jack gives you:

A System for modeling ANY articulated figure: a full hierarchical database, a complete joint library, active constraints, collision detection, real time kinematics and dynamic simulation. Human Bodies: anthropometric scaling based on a database or your measurements; high fidelity biomechanics with complex joints, and a fully articulated hand and spine model; automatic grasping to part contours with precision or power grasps and a full hand shape library, path walking locomotion, head-eye coordination, and balance behaviors. Real-time viewing environment: interactive viewing, multiple windows, lights and cameras, textures, and mirrors (real time!),


xii

Complete animation and task simulation systems: goal based animation, and task based simulation (walk, get, put), with automated frame-by-frame production of movie files. Powerful extensions: macro language, customizable menus, even embedded Lisp, Python, and Tcl/TK programming systems. Full VR system: complete, immersive capabilities; supports stereo glasses, head mounted displays (HMDs), data gloves, and full body motion tracking.

What are the Jack Products?

Classic Jack

Classic Jack is the stand alone offering from Siemens PLM Software for Human Factors and Ergonomic Analysis. Classic Jack has several add-on modules which will be covered in this paragraph and have separate training that is available. The first, 3D Body Scan can be used to create humans using existing body scans (such as the SAE CAESAR Scans). The second module, the Occupant Packaging Toolkit (OPT) can be used to maximize vehicle design for the occupant or user. The third is the Task Analysis Toolkit (TAT), which is used in the manufacturing communities to design better workplaces and maximize the safety of workers. Finally, the MoCap module, which adds the ability to connect to a wide variety of virtual reality hardware for immersive studies. Both the OPT and TAT have separate training manuals which explain the capabilities of the modules in greater detail. These modules can be obtained by contacting your Siemens PLM representative for an additional license (See Appendix E: Additional Jack Resources). Jack can also be extended through a powerful scripting interface.

Teamcenter Visualization Jack (TcVis Jack)

VisJack is the Jack human model inside of VisMockup. It offers many of the same capabilities as Classic Jack. Just like Classic Jack, VisJack enables you to:

Insert digital men and women, and scale them by stature and weight

Define behaviors that condition how the digital humans react when postured

Posture digital humans by manipulating their joints

Evaluate what digital humans can see from their point of view or through the display of view cones

Evaluate the reach capability of digital humans


xiii

Utconferencing, and visualization software, the VisMockup prototypes can be quickly and easily evaluated by a design team without the need for each individual to have access to, and knowledge of Classic Jack.

NX Human

Based on the same Jack technology, NX Human Modeling helps enterprises across industries improve the ergonomics of product designs and associated workplace tasks during the design phase. The software enables the positioning of varying sizes of digital humans directly within the virtual design environment. By incorporating digital human modeling capabilities within the NX solution, designers can easily factor in ergonomic specifications from the very beginning in the design process.

product validation within the integrated environment for a quicker, more efficient and seamless product development workflow.

The embedded human simulation functionality extends the validation process beyond simple form, fit and function into the science of ergonomics. The ability to evaluate ergonomic considerations in a time effective manner leads to superior quality products that optimally accommodate users.

Process Simulate Human

Part of the Tecnomatix assembly planning solution that includes a broad range of applications to optimize assembly sequences; coordinate operation timing and kinematics; verify line performance, including throughput and resource utilization; perform line balancing and analyze production costs. Process Simulate (PS) Human allows users to verify the design of a workstation, ensuring that product parts can be reached, assembled and maintained. PS Human provides powerful capabilities to analyze and optimize the ergonomics of the human operation, thus ensuring an ergonomically safe process according to industry standards. PS Human also incorporates Motion Capture and Virtual Reality solutions, allowing the user to synch with their motion tracking devices. Using the various human simulation options within PS, the user can perform realistic simulation of the human tasks and optimize process cycle times according to industry standard timing evaluation methods. The result is process plan containing a full description of how a product is assembled, manufactured, tested and packaged. This plan becomes the basis for collaboration among planning teams, plants, suppliers and contractors.

All above icons perform an immediate action or pull up the appropriate dialog box except the OBJECT SELECTOR. This function effects subsequent actions in the Graphics Window and will be covered later in this manual.

Note: It is always good practice to verify that the expected object type is displayed in the OBJECT SELECTOR icon window before attempting any object manipulation.

Object Selector

The OBJECT SELECTOR works in conjunction with the GRAPHICS WINDOW. The current object type determines which CONTEXT SENSITIVE MENU is displayed when you on the object or the Object type in a Pick mode.

CONTEXT SENSITIVE MENU: Figure, Segment, Site, or Joint (These will be defined in Chapter 2). You can select through the OBJECT SELECTOR S DROP-DOWN LIST or scroll through the basic object types by pressing the in the GRAPHICS WINDOW. You can also access Window Parameters though context Sensitive Menus by Right Clicking away from objects in the GRAPHICS WINDOW. Pick Mode searches for specific object types in the GRAPHICS WINDOW. In this case, the object type is automatically changed when you press the corresponding hand selector

select Faces, Edges, and Nodes.

Move Controller

The MOVE CONTROLLER contains controls for moving all object types in the Jack environment. Since this is a major part of working with Jack, it is constantly in view and easily accessible.


Page - 5

Use the Hand Selector to select the object to move. Jack utilizes a Cartesian coordinate system, simply a triad of X, Y, and Z axes in space, to define position and orientation. You can enter the coordinates in the MOVE CONTROLLER or interactively move objects using the mouse.

Move Controller

You can move a figure along the x or z-axis by holding down the left mouse button or right mouse button , respectively. To move the figure up (along the y axis) use the middle mouse button . A large red arrow indicates the selected direction of movement. You can also rotate a figure around any axis by holding down the key and , or . The 3D Reference (XYZ) can be relative to a global reference or a local reference specific to an object. However, the coordinates displayed in the MOVE CONTROLLER are always global coordinates. LMB Translate along the x-axis MMB Translate along the y-axis RMB Translate along the z-axis

SHIFT LMB Rotate about the x-axis SHIFT MMB Rotate about the y-axis SHIFT RMB Rotate about the z-axis

Commands for moving objects with the mouse

Note: Simultaneously holding down two of the mouse buttons allows you to move objects in the plane spanned by the two corresponding axes.

Move - By

This feature allows any figure to be moved based on an arbitrary reference point. Jack already had the ability to apply "snap" to a human figure's H-Point; this feature makes it possible to snap, or


Page - 6

indeed apply any other move, to any figure, based on any existing Site or Node.

JT figures do not have native Jack geometry, and in particular, no Nodes. For these figures, the "Move By Node" is not available. However, "Move by Site" presents an alternate method of moving these figures when the root site is defined at the scene's global origin rather than local to the figure's geometry. Create a site on the object's geometry by using the "snap-to-cursor" move command to set the site location. Now one can move a JT figure by a site on the geometry which makes transformation adjustment more intuitive.

For human Figures, a Move By Site other than the root may contradict some behaviors or constraints. For example, requiring that an Arm "hold relative to object" and then trying to move the human by its shoulder! Be aware that some combinations may cause the human figure to "collapse" under the contradictory demands. It is usually best to only move a human when its Balance behavior is "release".

Global vs. Local Transformations

Movement operations described so far operate along the global coordinate axis. It is sometimes convenient to translate or rotate along an axis associated with the figure itself. Global and Local Transformations provide a method to interactively position an object relative to the global environment or its current orientation.

Global Transformation

Local Transformation

Snap to Geometry

Direct manipulation is well suited for global or gross movements but it can be difficult to adjust things relative to other objects. The SNAP TO options provides a powerful way to precisely position objects relative to each other. They are available anytime you are using the MOVE CONTROLLER. The different snap to options are described below and more detailed definitions can be found in the Appendix.

Graphics Window

The GRAPHICS WINDOW contains the 3D scene. You can have multiple GRAPHICS WINDOWS with different camera views or attachments in each and the GRAPHICS WINDOW can be resized at any time. The computation, graphics, user interface, and the total processing rates are displayed in the upper right hand corner. Additional information describing the overall efficiency of the scene is also presented here.

Graphics Window

Change View

Changing the view is a very basic operation in Jack. A view change can be done at any time just by holding down the key. Whenever the key is depressed mouse movement manipulates the camera location. Releasing the key returns operation to whatever you were doing before.

View Coordinate Reference

A yellow cross hair or coordinate frame will appear in the window when you change view. This represents the focus point or View Reference of the camera. Notice that as you move the mouse with the pressed the camera rotates about the center focus point. The focus point stays fixed relative to the geometry as you do this. Notice the difference between side-to-side mouse movement and up/down mouse movement.

Mouse movement with the pressed translates the camera. The focus point moves relative to the geometry during the translation. Again, notice the difference between side-to-side movement of the mouse and up/down movement. Finally, the zooms the camera in and out on the focus point. The only functional movement with the mouse when zooming is up/down. Depressing the and keys simultaneously manipulates the scene by moving the View Reference. Notice that now as you move the mouse with the pressed the geometry in the scene rotates around the camera. Pressing the translates the focus point relative to the camera. The geometry moves relative to the focus point. Notice that the end result is the same as when only the key was depressed.

Commands for changing view with the mouse

Note: A great mnemonic device is to remember:

Ctrl = Camera Shift = Spin Figure

Context Sensitive Menus

Context sensitive menus allow you to easily access menu options that are specific to a certain type of entity (human figures, non-human figures, segments, joints, sites, nodes). The provides rapid access to these context sensitive menus. The OBJECT SELECTOR ICON (on the Toolbar) controls the type of entity that will be selected and which menu options will appear when you press the . The OBJECT SELECTOR will be covered in more detail in subsequent chapters.


Page - 12

Context Sensitive Menus

The Window pop-up menu that appears provides access to basic view and window commands. The Window pop-up menu is available anytime you hold down the over an area of the window where there is no geometry, no matter what the OBJECT SELECTOR ICON is set to. Context sensitive menus differ for different objects, as they will display only the options relevant to that object.

Picking with the Middle Mouse Button

When objects (figures, segments, sites, joints etc) are overlapping, close together or obscured by other geometry it can be difficult to indicate unambiguously which one you wish to select. Sometimes simply manipulating the view can help. At other times, an alternative method of resolving the ambiguity is needed. In Jack the provides a way to resolve this ambiguity during a pick. If multiple selections surround the pick position, a SELECT ENTITY DIALOG will appear that contains a list of these selections.


Page - 13

Select Entity

Space Bar Completion

If you know the name of a figure, segment, site or joint you are trying to pick it can be easier to just type the name rather than trying to pick it with the mouse. SPACE BAR NAME COMPLETION makes it even easier. This feature is available in most text entry boxes.

Space bar completion

Note: Names are case sensitive.

International Menus

Jack allows users to customize the menus. For more information on available menus or customizing your own, please contact SIEMENS PLM SOFTWARE.
