This paper discusses user-interface and data structures for a triggered vision system, the Engine-VideoScope 513D. Usually, vision-systems for sophisticated evaluation purposes provide separate software-products for system configuration, online-inspection, digital image processing, and presentation. Individual products for various tasks originate only from the developers--but not from the customers-point of view. The user has to work with powerful tools although only a few features might be sufficient for his work. Instead of concentrating on his problem, he repeatedly has to operate with applications from various vendors, interfaces, data management and documentation. Our approach is not just to provide an application for image acquisition. We referred to the users needs for a delimited field of applications, considering both, hardware technology and typical evaluation steps. We will show, that a properly designed user-interface can drastically improve the working- efficiency and the level of acceptance from the users. The Engine VideoScope was originally designed to inspect and interpret processes in the field of powertrain engineering. However, providing an open software architecture and data- structures could be suitable for prototyping machine vision systems or even the base for products in various fields.
