  • Automatic Transcription of the Basic MTM-2 Motions in Virtual Reality
    Item type: Conference Paper
    Gorobets, Valentina; Andreopoulos, Emmanouil; Kunz, Andreas (2024)
    Progress in IS ~ Smart Services Summit: Building Resilience in a Changing World
    This paper presents our approach for the automatic transcription of the MTM-2 basic motions in VR. We give an overview of what Methods-Time Measurement (MTM) is and how it is used for the improvement of manual workplace layouts. We describe the conventional approach used to deliver MTM codes by the MTM experts and explain the benefits of using automatic transcription in comparison to the conventional approach. We discuss the reasonability of using our approach and potential use cases for it, followed by presenting the hard- and software used for our implementation. Further, we explain the user study procedure that was used to receive data for the assessment of the proposed automatic transcription. Lastly, we present the metrics we used to evaluate our algorithm and deliver measurable results based on those metrics. In conclusion, we summarize our work and present ideas for future work on this topic.
  • BIM-Enabled Issue and Progress Tracking Services Using Mixed Reality
    Item type: Conference Paper
    Holzwarth, Valentin; Steiner, Sebastian; Schneider, Johannes; et al. (2021)
    Progress in IS ~ Smart Services Summit. Digital as an Enabler for Smart Service Business Development
    This paper reports on a case study in collaborationwith an industry partner to explore the value creation potentials of Mixed Reality (MR) in construction. MR is a technology that allows for intuitive interaction with digital data through overlays on the real world, giving immediate access to the data of a construction site to quickly track or resolve possible issues. While prior research identified potential applications of MR in construction, the evaluation of MR in real contexts is lacking. Thus, this paper describes a user study that evaluates an MR-assisted inspection task with the participation of nine construction professionals. The results reveal that the average time needed to track an issue with the Building Information Modeling (BIM)-enabled MR application takes less than a minute, compared to an hour for the standard process. Furthermore, the participants reported that working with the MR application was enjoyable and they would like to use it more frequently. Finally, based on the user study’s findings, this paper develops two service concept prototypes that could be implemented by the industry partner.
  • Virtual Reality Extension for Digital Twins of Machine Tools
    Item type: Conference Paper
    Holzwarth, Valentin; Hirt, Christian; Gisler, Joy; et al. (2022)
    Progress in IS ~ Smart Services Summit: Smart Services Supporting the New Normal
    Digital twins (DTs) provide numerous opportunities for value creation in manufacturing. Services enabled by DTs include remote monitoring of assets' conditions and predictive maintenance. In this paper, we introduce novel, previously unexplored services based on a fully virtualized machine tool, which are targeted at increasing machine operators' productivity. This allows conducting procedures, such as operator training at a virtual machine tool, which results in the real machine tool being available for value adding activities. Beyond operator training, we envision further potential applications of the virtual machine tool including the run-in of new processes and collision detection.
