Towards Rapid Digital Prototyping for Augmented Reality Applications

In rapid continuous software development, time- and cost-effective prototyping techniques are beneficial through enabling software designers to quickly explore and evaluate different design concepts. Regarding low-fidelity prototyping for augmented reality (AR) applications, software designers are so far restricted to non-digital prototypes, which enable the visualization of first design concepts, but can be laborious in capturing interactivity. The lack of empirical values and standards for designing user interactions in AR-software leads to a particular need for applying end-user feedback to software refinement. In this paper we present the concept of a tool for rapid digital prototyping for augmented reality applications, enabling software designers to rapidly design augmented reality prototypes, without requiring programming skills. The prototyping tool focuses on modeling multimodal interactions, especially regarding the interaction with physical objects, as well as performing user-based studies to integrate valuable end-user feedback into the refinement of software aspects.
