Virtual reality content creation based on self-contained components in the e-learning domain: Re-using pattern-based vr content in different authoring toolkits

In the context of e-learning, it is challenging to incorporate emerging technologies, such as alternate reality games or Virtual Reality (VR), within current learning trends. Microlearning is such a current trend. It divides large and complex chunks of content into small and elementary learning nuggets. These single self-contained nuggets are then composed to overarching lessons or courses. The concept of VR nuggets dovetails this educational trend. VR nuggets are standalone, self-contained, and rather short VR experiences that can be combined with other learning nuggets. By using initial implementations of VR nuggets, they can be used to let authors create VR earning content, for example, to let learners experience alternate realities. In this paper, we further investigate the VR nugget authoring concept and extent it. We introduce two novel authoring toolkits that rely on VR nuggets – one based on context-related module interaction (CoNMoD) and one based on visual scripting (ViNS Tiles). In two separate user studies, we examine the acceptance of the toolkits and compare them to existing authoring environments that also rely on VR nuggets but utilize different interface techniques. These studies’ results emphasize the importance of exchanging content between different established tools and indicate the acceptance of our tools regarding their hedonic and pragmatic qualities, also compared to existing tools from related work. As a conclusion, we propose an exchange format for VR nuggets that supports their reusability. It enables authors that use different toolkits to work together. They can utilize VR nuggets created with other toolkits and still use their own preferred toolkit. By means of an expert survey, we draw conclusions on technical aspects and a suitable platform to make VR nuggets available to the community. This survey indicates that potential authors would use such an exchange-approach for creating and presenting VR content and that they are willing to share their work and to contribute in a VR nugget authoring community.
