Abstract Virtual reality (VR) has re-emerged as a low-cost, highly accessible consumer product, and training on simulators is rapidly becoming standard in many industrial sectors. Combined with the continued advancements in VR technology, the interest in platforms that generate immersive experiences has increased. However, the available systems are either focusing on gaming context, featuring limited capabilities (embedded editors in game engines) or they support only content creation of virtual environments without any rapid prototyping and modification. In this thesis, we focused on authoring tools and systems that generate or modify VR content, utilizing visual node-based editors or directly support prototyping from within the virtual environment (VR Editors). Thus, we propose an innovative coding-free, visual scripting platform to replicate gamified training scenarios through Rapid Prototyping via newly defined VR software design patterns. We implemented and compared three authoring mechanics a) classic scripting, b) visual scripting and c) VR Editor for rapid reconstruction of VR training scenarios based on our novel design patterns. Our Visual Scripting module is capable generating training applications utilizing a node-based scripting system whereas the VR Editor gives the user/developer the ability to customize and populate new VR training scenarios directly from within the virtual environment. In addition, we present the scenegraph architecture as the main model to represent training scenarios on a modular, dynamic and highly adaptive acyclic graph. To the best of our knowledge, there is no similar system that generates VR training scenarios utilizing such visual and virtual scripting tools. Inspired from game programming patterns, we implemented new design patterns for VR experiences. Such custom action prototypes support a variety of commonly used interactions and procedures within training scenarios offering great flexibility in the development of VR metaphors.
