“…This can improve situational awareness and make interaction simpler [22]. Alongside the improved spatial perception of the objects, virtual environments can enhance the communication between the dislocated participants as they enable speech and gesturing while at the same time viewing the product in true scale 3D environment when compared to the regular video conferencing tools [23]. Gong et al [24] investigated the application of VR collaboration in a globally distributed manufacturing company.…”

The study aims to explore the usefulness of existing VR 3D modelling tools for use in mechanical engineering. Previous studies have investigated the use of VR 3D modelling tools in conceptual phases of the product development process. Our objective was to find out if VR tools are useful in creating advanced freeform CAD models that are part of the embodiment design phase in the context of mechanical design science. Two studies were conducted. In the preliminary study, the group of participants modelled a 3D part in a standard desktop CAD application, which provided information about the key characteristics that must be satisfied to obtain a solid model from a surface model. In the research study conducted with a focus group of participants, who were firstly trained in the use of VR, the same part was modelled using a VR headset. The results were analysed and the fulfilment of key characteristics in the use of VR was evaluated. It was found that using VR tools provides a fast way to create complex part geometries, however, it has certain drawbacks. Finally, the ease of use and specific features of the VR technology were discussed.

“…Among these, human-RO interactions, which are interactions between a human and a real object, is difficult to apply to various remote collaborations since they require a physical object in the real world. Therefore, as a result of an investigation into research on remote collaboration based on MR, virtual reality (VR), and augmented reality (AR) conducted over the past three years on the other two interactions, the human-VO interaction was used more frequently than the human-human interaction [14][15][16][17][18]. These results seem to be due to the purpose of applying MR to remote collaboration.…”

“…In the remote expert scenario, the human-VO interaction was performed for the remote expert to manipulate the shared virtual object and to give work instructions to field workers. Coburn et al [17] conducted a remote collaboration application study of the co-annotation scenario, focusing on annotating objects or environments of user interest. In the co-annotation scenario, human-VO interaction was performed for users to check annotations that were left or to jointly annotate things or environments.…”

Various studies on latency in remote mixed reality collaborations (remote MR collaboration) have been conducted, but studies related to interaction latency are scarce. Interaction latency in a remote MR collaboration occurs because action detection (such as contact or collision) between a human and a virtual object is required for finding the interaction performed. Therefore, in this paper, we propose a method based on interaction prediction to reduce the time for detecting the action between humans and virtual objects. The proposed method predicts an interaction based on consecutive joint angles. To examine the effectiveness of the proposed method, an experiment was conducted and the results were given. From the experimental results, it was confirmed that the proposed method could reduce the interaction latency compared to the one obtained by conventional methods.

“…Mechanical engineering research predates the discipline of software engineering, and knowledge of design teamwork is an ongoing area of inquiry in our field [6][7][8][9][10][11][12][13]. However, in the case of real-time collaboration, software engineers have embraced the working style much earlier than mechanical engineers, and thus we look to practices in this field for inspiration.…”

With the availability of cloud-based software, ubiquitous internet and advanced digital modeling capabilities, a new potential has emerged to design physical products with methods previously embraced by the software engineering community. One such example is pair programming, where two coders work together synchronously to develop one piece of code. Pair programming has been shown to lead to higher quality code and designer satisfaction. Cutting-edge collaborative Computer-aided Design (CAD) technology affords the possibility to apply synchronous collaborative access in mechanical design. We test the generalizability of findings from the pair programming literature to the same dyadic configuration of work in CAD, which we call pair CAD. We performed human subject experiments with 60 participants to test three working styles: individuals working by themselves, pairs sharing control of one model instance and input, and pairs able to edit the same model simultaneously from two inputs. We compare the working styles on speed and quality, and propose mechanisms for our observations via interpretation of patterns of communication, satisfaction, and user cursor activity. We find that on a per-person basis, individuals were faster than pairs due to coordination and overhead inefficiencies. We find that pair work, when done with a single shared input, but not in a parallel mode, leads to higher quality models. We conclude that it is not Industry 4.0 technologies alone that influence designer output; choices regarding work process have a major effect on design outcomes, and we can tailor our process to suit project requirements.
