Physical prototypes and scale models play an important role in engineering design processes, especially in the field of industrial design. Such models are typically used to explore and discuss design concepts in various stages, from initial idea generation to manufacturing. Over the last decade, augmented reality technologies have been developed to assist prototyping in design.?we can employ head-mounted displays, projectors, or handheld video- mixing solutions, as well as 3d printing to “enrich” physical models with features, materials, and behaviour. The outcome of this project is a design support methodology, entitled interactive augmented prototyping methodology (iap-m), which utilizes augmented reality as an instrument to support design reviews. The instrument, a projection and recording unit, was patented and licensed to a techno starter for further valorisation. Although the instrumentation is central in this study, it requires procedures and methods to be applied in design processes. The insights that lead to iap-m originated from empirical studies and design inclusive research, and were implemented in a collection of demonstrators.
