“…Such alternating authoring can also introduce novel challenges. Existing work on VR authoring tools that incorporate immersive authoring techniques mentioned within our literature research focuses on creating a virtual environment entirely in a VR [e.g., (Dunk et al, 2010;Dunk, 2013)] or decoupling immersive and non-immersive authoring tasks to separate author roles within collaborative VR development [e.g., (Coelho et al, 2019;Nebeling et al, 2020)]. However, with respect to VR-nugget-based approaches, authors might perform such switching between immersive and desktop UIs frequently and multiple times, for example, for authoring several concise VR experiences.…”

Virtual Reality (VR) systems and VR content are complex, and their creation can mainly be conducted by experts in VR and related areas. That makes the use of VR challenging for experts from other domains, such as educators. In this paper, we build up on existing work and investigate the VR nugget concept—small self-contained VR systems that are built from educational design patterns. Particularly, we extend this concept and introduce structured authoring processes based on VR nuggets that show how standalone, combinable, and reusable VR software can serve as a meta-level guide for various VR applications and involve educators as domain experts. We conduct a user study with VR Forge, a VR-nugget-based authoring software tool, to draw conclusions on how pattern-based VR authoring tools should be designed to support domain experts. We compare our results with those of a related study of the VR nugget tool IN Tiles. Based on the comparative results of usability and hedonic quality measures, both anecdotal evidence and statistically significant results support the concept’s potential for VR authoring conducted by practitioners who are not experts in VR. We derive the recommendation that the design of a VR-nugget-based authoring environment will benefit from using both immersive and desktop user interface (UI) technologies and that the authoring workflow will need authors to frequently alternate between the technologies. We state findings and lessons learned from the development and the studies. We contribute insights in developing reusable and use-case-specific VR content and tools and propose authoring processes that focus on the tasks and goals of domain experts as the primary authoring role within educational VR development. Finally, the relevance of VR-nugget-based authoring is supported by anecdotal evidence gathered from over 3 years of investigating and applying it within three educational institutions and a company providing education services.

“…Collaboration as a concept for AR/VR tool creation has been around for some time, for example Schmalstieg et al 's Studierstube [70]. More recent AR/VR prototyping tools, such as XRDirector [60], additionally incorporate roles based on tasks or interdisciplinary collaboration [10]. However, the roles proposed in Section 4 are still at a high level and not yet unique to AR/VR teams as they can also be found in other software and game development teams.…”

“…In addition to approaches from classical UI development and flmography (e.g. [52,60,61]), we encountered gray boxing, a method applied in game design for creating low-cost prototypes to construct spatial layout and scaling properties. This bears striking similarities to the use and study of prototyping in systems design, as described by Floyd to include widget toolkits, very high level programming languages, and database-systems, in order "to make efective work possible" [33] , generate human-feedback, and "keep trying until you get it right" [16].…”

“…However, based on our fndings, this diferentiation between design space and application space is still imposed by authoring tools used in practice. In contrast to that, current trends in AR/VR authoring tool development, for example Nebeling et al [60] and Leiva et al [52], follow the "What You Experience is What You Get" (WYXIWYG) Editor principle from Lee et al [49][50][51], who proposed an immersive authoring tool for concurrent content creation and validation in the application space. WYXISWYG leans on the "what you see is what you get" approach of todays' graphical user interface editor prototyping tools.…”

Augmented/Virtual Reality (AR/VR) is still a fragmented space to design for due to the rapidly evolving hardware, the interdisciplinarity of teams, and a lack of standards and best practices. We interviewed 26 professional AR/VR designers and developers to shed light on their tasks, approaches, tools, and challenges. Based on their work and the artifacts they generated, we found that AR/VR application creators fulfll four roles: concept developers, interaction designers, content authors, and technical developers. One person often incorporates multiple roles and faces a variety of challenges during the design process from the initial contextual analysis to the deployment. From analysis of their tool sets, methods, and artifacts, we describe critical key challenges. Finally, we discuss the importance of prototyping for the communication in AR/VR development teams and highlight design implications for future tools to create a more usable AR/VR tool chain. CCS CONCEPTS• Software and its engineering → Collaboration in software development; • Human-centered computing → Human computer interaction (HCI); Interaction techniques.

“…The display of information (text or 3D representation) in space without connection to reality constitutes much less added value. This consideration is the heart of many augmented reality works [23,24]. Tracking consists of hooking a real element by identification to a defined virtual element, in order to position the entire virtual overlay in space.…”

Global industry is at the heart of its fourth industrial revolution, being driven by the emergence of new digital solutions: Augmented reality allows us to consider the evolution towards the “the augmented operator”. This technology is currently little used in higher education, especially for mechanical engineers. We believe that it can facilitate learning and develop autonomy. The objective of this work is to assess the relevance of augmented reality in this context, as well as its impact on learning. The difficulties for a student approaching a technical system are related to reading and understanding 2D and even 3D representations, lack of knowledge on components functions, and the analysis of the chain of power transmission and transformation of movement. The research is intended to see if AR technologies are relevant to answer these issues and help beginners get started. To that end, several AR scenarios have been developed on different mechanical systems, using the relevant features of the AR interfaces that we have identified. Otherwise, these experiences have enabled us to identify specific issues linked to the implementation of AR. Our choice of AR devices and software allows us to have an integrated digital chain with digital tools and files used by mechanical engineers. Finally, we sought to assess how this technology made it possible to overcome the difficulties of learners, in different learning situations.
