A Nugget-Based Concept for Creating Augmented Reality

Creating Augmented Reality (AR) applications can be challenging, especially for persons with little or no technical background. This work introduces a concept for pattern-based AR applications that we call AR nuggets. One AR nugget reflects a single pattern from an application domain and includes placeholder objects and default parameters. Authors of AR applications can start with an AR nugget as an executable stand-alone application and customize it. This aims to support and facilitate the authoring process. Additionally, this paper identifies suitable application patterns that serve as a basis for AR nuggets. We implement and adapt AR nuggets to an exemplary use case in the medical domain. In an expert user study, we show that AR nuggets add a statistically significant value to an educational course and can support continuing education in the medical domain.
