|Session Title||Code generation and domain-specific modeling for user interfaces of embedded devices
|Session Type||Case Study
In this session, we report on our product development experience based on state-of-the-art domain-specific modeling and code generation technology applied to user interface development for embedded medical devices. We discuss the technological challenges which have been encountered and solved as well as the business rationale behind our approach (in terms of ROI).
Our experience comes from an ongoing product development project in the embedded medical domain. B.Braun Medical Hungary and CJP LLC have teamed up for a 4-year development cooperation targeting the development of a modern touch-based graphical user interface for an extracorporeal blood treatment (ECB) equipment product line. From previous experience, it is known that UI development is a difficult and expensive endeavor, and a major source of software errors. However, from the marketing point of view, it is an extremely important aspect of the product, hence we consider the lessons we learned to be of significant value to any company involved in the embedded device business.
As for the novelties of this project, our aim is to create an attractive, modern, yet functional UI, based on vector graphics, touch-based interactions, and animations. Our flexible platform is powered by a web browser-based front-end. The UI itself is developed with our own end-to-end domain-specific modeling and code generation tool platform (based on Eclipse technology), which supports full code generation with the flexible integration of hand-written components and model-based documentation generation with complete traceability support.
In addition to the technological novelties, we discuss our business rationale behind developing such complex custom technology. From development and training costs to changes in development processes, adapting to such a state-of-the-art approach requires a significant investment. Our experience so far already clearly shows the advantages, long-term benefits, but also the pitfalls. Overall however, we firmly believe that this technology is the way forward in embedded UI development.
