Product Validation and Experience

The generic application scenario “Product validation and experience” aims at a partial or full virtual display of future products so that the user can experience them as realistically as possible. This is an essential development step, especially for human-centred products and complex environments, and it should be implemented during the early design stage. Vehicle cockpits are typical examples of product components that have a complex user interface and must therefore be checked and validated in great detail. Apart from aesthetic aspects, safety-relevant aspects for the validation of such components also need to be taken into consideration. In order to achieve the required reliability, the virtual scene must be available in high quality and with a high level of realism as well as representing an adequate image of the deployment environment of a product. A large variety of linked simulations as well as the integration and processing of different data sources ensured that the targets of creating these close-to-reality virtual environments and of experiencing a product in these environments based on the prototypes have already been achieved during the first half of the project. Geo information, 3D environment detection data, infrastructure elements of cities, landscape features, driving simulations, environment simulation, traffic, weather, on-board systems and many other components produce the overall image of the experienced environment, thereby providing the basis for assessing the product. These are predominantly independent systems or data sources that are already available. The ARVIDA reference architecture allows the integration of these functions and this data into the virtual world and the linking of these systems and data sources, which have been independent until now, as has been demonstrated during the first half of the project.

Application scenarios

The generic scenario is composed of the two application scenarios “The digital driving experience” (Daimler Protics GmbH) and “Interactive projection seating buck” (Volkswagen AG).

The digital driving experience allows an almost realistic interactive experience of a vehicle in a close-to-reality 3D environment. The experience environment is created and realistically displayed by the process to the best possible degree using information from various data sources, such as GIS systems and 3D scans of outdoor scenes. For the interactive projection seating buck, simple real models are enriched by realistic virtual details, for example by displaying instruments in their correct position using a front projection technique.

Evaluation

Based on the existing joint requirements and services, a generic application scenario for the joint evaluation is defined. While in the digital vehicle experience, a vehicle is moved in a virtual simulation environment, the interactive projection seating buck visualises the virtual data in the interior of a vehicle. As a result, vehicle properties and the status/information from individual vehicle systems can be exchanged between the two scenarios via the ARVIDA reference architecture. In this way, the interoperability and linking of two independent systems can be achieved.
