Method & Evidence

AimTo develop a virtual environment for ergonomic assessment of a car's interior and driver's seat position using digital mock-ups, thereby validating the design early in the development process.
MethodVirtual Prototyping and Ergonomic Simulation
ProcedureVirtual humans representing different percentiles (50th and 95th percentile American males) were created using CATIA V5's Human Builder module. These virtual humans were then used to conduct ergonomic analyses of the driver's seat within a virtual prototype of the car, simulating interactions in a semi-immersive virtual environment.

Strengths & Limitations

Strengths

  • +Pioneering application of VR for ergonomic assessment in a specific regional automotive context.
  • +Clear demonstration of cost and time-saving potential.

Limitations

The accuracy of virtual ergonomic assessments is dependent on the fidelity of the virtual environment and the realism of the virtual human models.

Reliability & validity

Reliability could be enhanced by using multiple virtual human models and repeating simulations. Validity is supported by the potential for direct comparison with physical prototype testing, though this was not performed in this study.

Think critically

How might the limitations of virtual human models in terms of representing diverse body types, cultural nuances in posture, or dynamic movement affect the reliability of virtual ergonomic assessments?

Design Principles

"Validate user interaction and comfort through digital simulation before physical realization to optimize design outcomes and resource allocation."

This approach enables designers and engineers to identify and rectify ergonomic issues during the digital mock-up phase. By simulating user interactions with virtual prototypes, design teams can ensure a higher standard of comfort and usability before committing to physical production, leading to more successful product launches.

What This Means for Your Design

Using computer simulations with virtual people can help designers check if a car's seats and controls are comfortable for different sized people before they build a real car, saving money and time.
