- Over the past decade, the value and potential of VR applications in manufacturing have gained significant attention in accordance with the rise of Industry 4.0 and beyond. Its efficacy in layout planning, virtual design reviews, and operator training has been well-established in previous studies. However, many functional requirements and interaction parameters of VR for manufacturing remain ambiguously defined. One area awaiting exploration is spatial recognition and learning, crucial for understanding navigation within the virtual manufacturing system and processing spatial data. This is particularly vital in multi-user VR applications where participants' spatial awareness in the virtual realm significantly influences the efficiency of meetings and design reviews. This paper investigates the interaction parameters of multi-user VR, focusing on interactive positioning maps for virtual factory layout planning and exploring the user interaction design of digital maps as navigation aid. A literature study was conducted in order to establish frequently used technics and interactive maps from the VR gaming industry. Multiple demonstrators of different interactive maps provide a comprehensive A/B test which were implemented into a VR multi-user platform using the Unity game engine. Five different prototypes of interactive maps were tested, evaluated and graded by the 20 participants and 40 validated data streams collected. The most efficient interaction design of interactive maps is thus analyzed and discussed in the study.

- This study studies the challenges of effective communication and collaboration in remote design review meetings (DRMs) and explores the potential of Extended Reality (XR) technologies to address these challenges. The research focuses on identifying recurring communication issues and the preferences of companies within the context of remote DRMs. The study involves qualitative content analysis and industry workshops to uncover the current problems with conventional approaches and the aspirations of companies regarding improved collaboration in the DRM process. Drawing upon the insights gathered from both the workshop and design review observations, this paper highlights the features that are critical for collaborative software to handle online design reviews. XR technologies offer immersive and interactive experiences that can transform communication and collaboration in the context of DRMs. By identifying the specific challenges faced in remote DRMs and understanding the desires of companies, this study sets the stage for a more efficient and effective collaborative process. It emphasizes the adaptability of XR technologies to meet industry needs and integrate seamlessly into existing workflows. The study concludes by highlighting the potential for XR technologies to enhance collaboration in DRMs, making them a valuable tool for various industries.

Exploring the current applications and potential of extended reality for environmental sustainability in manufacturing
- 2023

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In response to the transformation towards Industry 5.0, there is a growing call for manufacturing systems that prioritize environmental sustainability, alongside the emerging application of digital tools. Extended Reality (XR) - including Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) - is one of the technologies identified as an enabler for Industry 5.0. XR could potentially also be a driver for more sustainable manufacturing: however, its potential environmental benefits have received limited attention. This paper aims to explore the current manufacturing applications and research within the field of XR technology connected to the environmental sustainability principle. The objectives of this paper are two-fold: (1) Identify the currently explored use cases of XR technology in literature and research, addressing environmental sustainability in manufacturing; (2) Provide guidance and references for industry and companies to use cases, toolboxes, methodologies, and workflows for implementing XR in environmentally sustainable manufacturing practices. Based on the categorization of sustainability indicators, developed by the National Institute of Standards and Technology (NIST), the authors analyzed and mapped the current literature, with criteria of pragmatic XR use cases for manufacturing. The exploration resulted in a mapping of the current applications and use cases of XR technology within manufacturing that has the potential to drive environmental sustainability. The results are presented as stated use-cases with reference to the literature, contributing as guidance and inspiration for future researchers or implementations in industry, using XR as a driver for environmental sustainability. Furthermore, the authors open up the discussion for future work and research to increase the attention of XR as a driver for environmental sustainability.

- Virtual reality (VR) technology have become ever matured today. Various research and practice have demonstrated the potential benefits of using VR in different application area of manufacturing, such as in factory layout planning, product design, training, etc. However, along with the new possibilities brought by VR, comes with the new ways for users to communicate with the computer system. The human computer interaction design for these VR systems becomes pivotal to the smooth integration. In this paper, it reports the study that investigates interaction design strategies for the multi-user VR system used in manufacturing context though an automotive case study.

- Musculoskeletal disorders (MSD) as a result of bad workplace design and ergonomics are one of the leading causes of work-related injuries, this is especially true for assembly workers within the manufacturing industry. This paper investigates the possibilities to implement an automated ergonomics evaluation assessment into a Digital Human Modeling (DHM) software to evaluate workplace design for assembly tasks within manufacturing. A benchmarking and screening process was conducted to identify the most suitable ergonomics assessment method to be implemented into the DHM software. Furthermore, a pilot implementation, using Industrial Path Solution (IPS) Intelligently Moving Manikin (IMMA) as the referenced DHM software, was held with China Euro Vehicle Technology (CEVT) to solidify the results of the integrated function. This paper showcases that automated ergonomics assessment methods can, successfully, be integrated into a DHM software.

The Creation of a Multi-User Virtual Training Environment for Operator Training in VR

Konferensbidrag (refereegranskat)abstract
- Many industries are today heavily exposed to competition which increases the demand for continuous innovations, faster product changes and continued improvements, this is especially true for the automotive industry. Such demands raise the complexity and set a need for continuous training and development of our operators and assembly personnel to keep up with new designs and product changes. This, in combination with an aging population and a growing shortage of experienced assembly workers, increases the need for efficient training capabilities.Today most of the operator training is supervisor driven and takes place in the live production environment working with real products. This approach might introduce uncertainties and a risk to the production system as less experienced workers, still in training, might jeopardize quality, ramp ups and takt time. With the rise of virtual reality there are growing possibilities to carry out these training sessions in a more secure, non-disruptive, virtual environment without jeopardizing ramp ups, takt time or quality. This paper evaluates the possibility to introduce virtual multi-user operator training as an alternative to traditional supervised “on-site” training for assembly workers. Recreation of different assembly task from an automotive case company was created in virtual reality while introducing multi-user functionality to allow multiple operators and supervisors to observe, instruct and evaluate the performance of the operator in training. The developed demonstrator is used as the discussion basis throughout a focus group interview study with selected participants from an OEM case company and the potential of a multi-user virtual reality application as a complement for traditional operator training in operator training is discussed and future research directions for multi-user virtual reality trainings at OEMs is presented.
