Virtual Reality
platform giving
engineers easy access
to the digital product

RHEA (Realistic Human Experiment Analysis) has been co-developed by OPTIS and EADS Innovation Works and has been in daily use by EADS over the last 5 years. It offers a virtual reality platform for carrying out ergonomic studies on future products, their manufacturing process and maintenance schedules. Both the designer and ergonomist can take the place of the future pilot, driver, crew member, passenger and technician to experience multiple tasks with a view to globally exploring different technical solutions, interacting with the virtual mock-up, placing the human in the center of the design process. To enhance the realism of the analysis, RHEA enables users to place the future product inside animated environments thanks to a scenario manager. A unique CAD to VR transfer function has been developed to manage huge CAD CAM models such as complete aircraft inside your VR Center.
