VREUD - An End-User Development Tool to Simplify the Creation of Interactive VR Scenes

Towards Sustainable Virtual Reality: Gathering Design Guidelines for Intuitive Authoring Tools

“…In terms of usability evaluation methods, nine studies adopted Likert-scale surveys [32] [33] [37] [8] [17] [10] [40] [41] [12], three used SUS [35] [10] [12], four adopted other types of questionnaires like ASQ and NASA TLX [35] [37] [39] [41], three used qualitative retrospective interviews [36] [8] [10], two implemented other methods like the "thinkingaloud method" or measured the number of errors and time taken to complete the activity [38] [39], and only one didn't use any evaluation methods [34]. Table 2 shows how almost all of the authoring tools, using various methods of evaluation, presented similar conclusions, which are often described in terms of being intuitive.…”

“…[40] "We choose user interface elements [...] to minimize learning time [...]" "it was useful to see each others' work in real time to improve workspace awareness, and it was easy to share findings with one another" [41] "Evaluation results indicate the positive adoption of non-experts in programming [...] participants felt somewhat comfortable using the system, considering it also as simple to use." [12] "[...] we have analyzed the effectiveness, efficiency, and user satisfaction of VREUD which shows promising results to empower novices in creating their interactive VR scenes. "…”

“…• "Compared to the logic used in the construction of interactions, the task construction uses generic activities which should be also clear to novices without a technical background, since they are comparable to actions in the real world" [12].…”

“…These factors contribute to the technology's lack of maturity, leading to the difficulty of defining best practices for multiple user applications, the lack of standardized processes, the lack of recommended practices, the lack of a common language, and the lack of interoperability between VR tools and between pre-existing data such as 3D assets and codes [6] [11] [14] [17]. Combined with the complexity of virtual reality systems architecture, these barriers contribute to the persistence of novices' learning difficulties, requiring good prior knowledge to utilize the full potential of the tool [12].…”

Collaborative Software Modeling in Virtual Reality

“…Avatars) are in. Overall, the fast development in VR concerning prototyping [13] and engineering of VR applications [14] as well as the mentioned technological advances allow us to extend the research field to improve the quality of UML and collaborative modeling. Thus, the main goal of this paper is to explore the potential of using Virtual Reality (VR) technology for collaborative UML software design by comparing it with classical collaborative software design using conventional devices (Desktop PC / Laptop).…”
