Virtual reality application influences cognitive load-mediated creativity components and creative performance in engineering design

Virtual reality (VR) can promote design performance, and may generate a high cognitive load and affect creative design thinking as well. In order to examine the effect of VR application on cognitive load and engineering design creativity, this study recruited 81 eighth-grade students as participants and employed a non-equivalent-groups quasi-experimental design to examine how VR application influences creativity components and creative performance. A creativity component scale (creative motivation, creative thinking, and professional cognition), a measurement of creative performance, and a cognitive load scale were used to collect data. The study also investigated the ability of VR application to predict creativity components and creative performance, using cognitive load as the mediator. The conclusions are as follows: (1) VR application had marked effects on professional cognition and creative motivation but no effect on creative thinking skills. (2) VR application had marked effects on the novelty and usefulness aspects of creative performance, particularly with respect to usefulness. (3) VR application had marked effects on extraneous and germane cognitive load, but no influence on intrinsic cognitive load, and (4) Both VR application and cognitive load were able to predict creativity components and creative performance. Their abilities to predict creative performance approached an acceptable level. Nevertheless, VR application had no effect on general creative thinking skills; therefore, other teaching strategies are needed to strengthen creative thinking.     

An effective FoV restriction approach to mitigate VR sickness on mobile devices

It has been noted that restricting field of view (FoV) is effective to mitigate virtual reality (VR) sickness, but it is prone to reduce the immersiveness. We propose an effective FoV restriction approach to mitigate VR sickness on mobile devices. The proposed approach includes a practical and reliable method for measuring VR sickness and a method of effectively limiting the FoV on mobile VR devices. Experimental result shows that the proposed method reduces VR sickness by 31.4%. The method was successfully applied to a VR application.

Applications of virtual reality in maintenance during the industrial product lifecycle: A systematic review

As a state-of-the-art computer technology, virtual reality (VR) is considered to play an important role in helping manufacturing companies stay competitive in the international market. However, despite the achievements made in the field of VR, it is still an emerging technology that lacks deeper exploration and development in industrial application scenarios, especially in the coming fourth industrial revolution (Industry 4.0). This paper aims to systematically investigate the applications of VR in industrial maintenance to discover evidence of its values, limitations, and future directions so that VR can be guided to better serve manufacturing enterprises in remaining competitive in the coming Industry 4.0. A systematic literature review (SLR) methodology is adopted to review primary studies on this topic, by which 86 studies are ultimately included. The results show that VR has proved its value in benefiting maintenance issues through the product lifecycle. However, VR is still not an indispensable element for the lifecycle management of products regarding maintenance-related issues. Several key findings are concluded based on the analysis of the 86 studies. This review is valuable for researchers who are interested in the application of VR technology in maintainability design, maintenance training or maintenance task assistance.
