Visual ergonomics As well as looking at how these components perform at the system level, OEMs are increasingly looking at how the complete systems work together in a complete package. Especially of interest is how these new features interact with each other, how they are perceived by the driver, and how they affect the visual ergonomics of the car's interior. More light and more innovative design and materials means more reflections and possible problems with legibility. Many car makers are turning to advanced simulation solutions to identify potential issues and provide alternatives to physical mock- ups through simulation to find solutions for optimizing the driver's vision. Using the Visual ergonomics package from OPTIS, customers are able to create accurate models of the car interior, using interior and exterior light sources, taking into account human vision thanks to OPTIS's unique human eye model. This model allows customers such as Fiat to identify potentially intrusive reflections, glare and legibility issues, in a simulated environment to eradicate these issues at source. Such a setup means that customers can still benefit from these advances in design and innovation without compromising the driving experience. " The fact that our solution is embedded in native CAD systems such as CATIA V5 means that any issues shown as a result of the simulation can be modified in the native CAD format and simulated and verified without leaving the design environment," explains Moorhouse. " Using OPTIS' Visual ergonomics package, customers are able to create accurate models of the car interior, using interior and exterior light sources"
" This immediate response to design and styling demands means that designers and engineers can work together early in the design stage with no time or effort lost from inaccurate translation processes". By working in a physics- based environment users can simulate the effect of different materials on the car interior and how these interact with different lit conditions. This means that very early on, designers can make important choices on the exact materials and which LEDs to choose. They can also see subtle changes in reflective or diffused materials and finishes to create the right ambient lighting effect that will attract potential customers - making it stand out without compromising the driver's visual comfort. What's next? As engineers and designers work more closely to create more visually pleasing solutions, today's standard design reviews that discuss and review engineering and styling options can now include lighting design and optimization. The next challenge for OPTIS is to display these simulation results in a 3D design review environment using large screen projections or caves. Through an interactive VR environment, users, designers and maybe even consumers, will be able to make not only style, but quantitative decisions, based on the simulations provided by this technology. These decisions can be taken not just on a rendered image but in 3D, physics- based simulations built using CAD geometry, real materials, light sources and environments, human vision- based software to give the user the experience of a very human perception of light in the dark. Through large screens and VR- based caves, design reviews will allow designers and engineers to review designs and style issues in a more natural and realistic environment than through a computer screen.
