Six human factors analysis tools that help you design vehicle interiors for optimal occupant comfort and performance-without building costly physical prototypes. The Occupant Packaging Toolkit is a set of six human factors analysis tools that help you design vehicle interiors for optimal occupant performance and comfort. An add-on to Jack 2.2i, OPT provides tools for:

• SAE Packaging Guidelines
• Posture Prediction
• Comfort Assessment
• Advanced Reach Analysis
• Advanced Anthropometry
• Specialized Part Libraries

SAE Packaging Guidelines

The SAE Packaging Guidelines tool implements 28 of the SAE recommended practices for various driver and vehicle design attributes. With this tool, you can:

• Quickly and easily create geometry in Jack to identify zones where physical features such as eyes, head clearance and fingers would be located for 95% or 99% of the population
• Quickly and easily create geometry to identify locations for such vehicle attributes as the seat, steering wheel, armrest, gear shift, wiper and defroster zones
• Automatically recompute the location of these driver and vehicle geometry locations just by modifying the critical reference points

Posture Prediction

The Posture Prediction tool helps you place Jack virtual humans in seated postures that represent how people of a particular anthropometry actually sit in the driver's seat of an automobile. Based on empirical studies of hundreds of occupants seated in various vehicle configurations, the tool:

• Predicts the location of Jack within a vehicle package, taking into account the size of the virtual human and the packaging layout
• Automatically computes pelvis orientation, spine curvature, and head position
• Uses inverse kinematics to solve the location of arm and leg joints based on specified hand and feet locations

Comfort Assessment

The Comfort Assessment tool helps you determine whether you've positioned a Jack human model in a comfortable posture. With five comfort models available to assess seated comfort, the Comfort Assessment tool:

• Predicts whether a given Jack model is in a comfortable seated posture based on individual joint angles and overall body posture
• Allows you to set your own comfort ranges for individual joints several options for reporting your findings, including real-time bar graphs that dynamically display the comfort ranges of individual joints or body parts as you position your Jack model

Advanced Reach Analysis

The Advanced Reach Zone tool helps you generate zones that depict the areas of maximum and comfortable reach for specific Jack digital humans. With this tool, you can generate:

• Joint-driven maximum reach zones depicting full movement of both shoulders and the waist
• Constraint-driven maximum reach zones factoring in such constraints as seat belts, steering wheel hand positions, head locations and more
• Comfortable reach zones for the shoulder, elbow, wrist, hip, knee and ankle joints based on the industry's most recognized sources of comfort data

Advanced Anthropometry

The Advanced Anthropometry tool helps you create Jack humans with specific anthropometric measurements. With this tool, you can:

• Create human models with specific anthropometric measurements for 24 different body dimensions
• Create individuals for accommodation studies in which a single dimension is changed at a time
• Scale human models to match the measurements of real subjects

Specialized Part Library

The Specialized Part Library provides an assortment of useful geometry that a designer might need to evaluate a vehicle interior design. With this tool, you can access such parts as accelerator and brake pedals, bench and bucket seats, gear shifters, parking brakes, rear view mirrors, and sun visors.
