Enabling Non-Professional Users To Bring Physical Processes Into The Industrial Metaverse

Augmented reality is essential for the Metaverse because, with this technology, people, spaces, and things can be digitally and physically intertwined. But the creation of AR content is a very complex process carried out by technically skilled developers. For the Metaverse, it is necessary to enable non-professional users to create AR content. We, therefore, want to study the challenges that non-professional users face while creating AR content for process guidance systems that represents a physical process. For this reason, we conducted an exploratory analysis using ten AR authoring experts and arranged a focus group with domain experts and AR authoring experts. As a result, we identified four fundamental design requirements on how an AR authoring tool must be designed to bring physical processes into the Metaverse. Thus, we contribute to understanding AR-based process guidance systems and enable the instantiation and evaluation of an AR authoring tool in large DSR project

User-Centered Requirements for Augmented Reality as a Cognitive Assistant for Safety-Critical Services

Augmented reality (AR) is widely acknowledged to be beneficial for services with exceptionally high requirements regarding knowledge and simultaneous tasks to be performed and are safety-critical. This study explores the user-centered requirements for an AR cognitive assistant in the operations of a large European maritime logistics hub. Specifically, it deals with the safety-critical service process of soil sounding. Based on fourteen think-aloud sessions during service delivery, two expert interviews, and two expert workshops, five core requirements for AR cognitive assistants in soil sounding are derived, namely (1) real-time overlay, (2) variety in displaying information, (3) multi-dimensional tracking, (4) collaboration, and (5) interaction. The study is the first one on the applicability and feasibility of AR in the maritime industry and identifies requirements that impact further research on AR use in safety-critical environments
