Virtual reality (VR) technologies and computer-generated technologies are very useful for many industries, such as medical, education, gaming, mining, engineering, and other sectors. In engineering sector specifically for assembly department, the major problem they are facing was that traditional components of automotive engine are complex and very difficult to assemble using current method which use paper manual. The goal of this project is to create an interactive VR application such that users can quickly integrate and perform the work easily. In this work, the authors designed and developed an immersive VR application with several stages, such as 3D model creation, visual effects creation and gaming scene building. The application was built using Unreal and HTC vive headset. As this is an on-going project work, further functionality will be added to render the application immensely for users and assist the sense of pedagogy in terms of the digital method of learning.
Training and education have become increasingly crucial in obtaining new skills in a variety of fields, especially in assembly and disassembly operations. The main issue in mechanical engineering, particularly in the assembly department, was that automobile engine components assembly was found to be complicated and challenging to assemble using an existing method, where they only rely on a video-based method. The purpose of this paper is to create interactive Virtual Reality (VR) and Augmented Reality (AR) applications that allow users to efficiently assist and complete the assembly tasks. In this work, the authors designed and developed a fully immersive VR application using an HTC Vive headset and two AR applications (marker-less AR application and marker-based AR application) using EPSON MOVERIO BT-300 (AR Smart Glasses). Fourteen engineering students from Universiti Putra Malaysia were selected for the experiment. They were divided into four groups: video-based group, VR-based group, marker-less AR group, and marker-based AR group. They are required to complete all four experiments (video-based experiment, VR-based experiment, marker-less AR experiment, and marker-based AR experiment). The results showed that the marker-less AR application is the best impressive method (37% better), the VR application is the second impressive method (23% better) followed by the marker-based AR application is the third impressive method (3% better) compared to the existing video-based guideline. Therefore, the students favored AR and VR applications rather than the existing method to be used in automobile engine assembly tasks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
